My stepson Riley was about 10 when I married his mother. It took him a while to get to a point where he wasn't standoffish with me. Things have improved over the couple of years we've been married. There have been times I've wondered if the distance was because of something else because I've often caught him taking long looks at the bulge in my clothing. I'm not gonna lie and say I haven't thought about doing things with him. I'm not really into guys (though I did occasionally mess around with my bestie when I was a teen), but there's something about his blonde hair, fair skin, and thicker lips that just gets me when I see him checking out my crotch.
One morning things took a nice turn. His mom started a new job where she has to leave a lot earlier in the mornings. I usually get up a bit before Riley wakes. That morning I was lazing in bed since it was a weekend. I was feeling pretty horny and decided a nice slow jack would be a nice start to my day. I had the blanket and sheets off, and my Johnson was standing at full attention when I heard the doorknob start to turn. Instead of covering up, I decided to just see what happened. I pretended to be asleep.
As the door opened, I slightly creaked one eye open so I could see his response. When he saw my hard cock, his eyes got really big. He slid into the room and slowly walked toward the bed. His curiosity made my dick twitch. 
I quickly thought of how I could maybe test things out. “Mmm, Maggie. You're so hot,” I said, using his mother's name.
He stopped by the bed.
“Yeah, Maggie. Come on, take my cock. You got me all hot, baby.”
He stood motionless. Deep down I wanted to just grab his hand and guide it to my stiff meat, but I knew that would freak him out. Plus I wanted him to be the one who started stuff. Just to be safe.
“Come on, baby. You got me all hard. Don't leave me suffering.” I squirmed a little for effect.
I couldn't see his face well since I had to keep my eyes mostly closed, but it did seem that he was tempted.
“Maggie, you're being such a bitch!”
I almost jumped when I felt his fingers wrap around my dick.
“Yeah, baby. Take care of me.”
He began slowly stroking me. I felt so fucking fantastic. I could see his small hand on my hard-on, and man it made me excited.
After he did this for a bit, I got brave: “Suck it, baby.” I waited hopefully, but he stood frozen. “Don't be mean, Maggie. Put it in your mouth for me.”
I saw him move his head downward just a bit, but then he stopped. I went ahead and put my hand on his arm. “Come on, baby. You know how much I like a good blowjob. Make me happy, Maggie.” I slid my hand up his hairy arm. When I reached his shoulder, I slid it up his soft neck. Then I ran my fingers through his hair. Once I was at the top of his head, I guided his head down. My heart was pounding in my chest!
He didn't resist, and soon his lips were pressed against the tip of my straining meat. “Open wide, baby,” I said. A couple of seconds later, I melted as I felt my cock slide into his mouth. “Baby, you got me so hard! Move your head up and down. Let me get more in your mouth.”
He began blowing me, and I felt him relax as he started getting going. He was slowly moving his lips up and down my shaft, and it was marvelous. With his attention focused on my cock, I could open my eyes a bit more. It was so fucking hot to watch him working my rod.
As he sucked me, he started getting into it more. I rubbed his back through his shirt. Eventually I was brave enough to let my hand go down his back. Soon I was rubbing his butt through his pajamas. “Oh baby. You have such a fine ass.” When this didn't seem to scare him, I went ahead and yanked his bottoms down. “Let me feel that hot ass.” He was wearing briefs, so I had to pull those down, too. I began rubbing his bare, soft butt.
He seemed to really like this as he began sucking me faster and going down on me more. I decided to see where things could possibly lead. I wet my middle finger and began rubbing it on his tight hole. I went ahead and pushed it into him. He stopped sucking just for a moment. I opened my eyes a bit more and was pretty sure I could see a look of pleasure on his face. I reached out with my other hand and gently guided his head.
As I fingered his hole, he started sucking me more earnestly. Soon I felt him using one of his hands to explore my ball sac. I started moving my hips back and forth, and I pushed his head down more firmly. After this, I added my index finger. I was pretty sure I heard him moan.
“Oh gawd, baby! Yes, suck that fucking cock!”
He had me close, so I sped up my finger banging and pushed them in deeper. He moaned again and began making himself gag trying to devour more of my cock.
“Fuck yes, Maggie! Take as much of that big cock as you can!” I knew he wouldn't be able to get it all in his mouth, but I was so thrilled he was going to try.
It didn't take long before I was ready to blow. “I'm gonna cum, baby! Remember to swallow it all like you promised.”
A few moments later, my dick was blasting his throat with my jizz. He started swallowing right away, and my meat gave him quite a few bursts to work down.
“Thank you, baby. That was fucking awesome. One of the best you've ever done.” As I watched him pull up his pajamas and underwear, I spotted his little erection. “Let's do this again tomorrow morning, baby.”
I waited until he was out of the room and closed my door before I sat up. What the fuck! I thought. I was amazed and ecstatic that had just happened. 
After several minutes, I heard a knock at the door. I covered myself and sleepily said he could come in. I rubbed my eyes like I had just woke up. “Hey, Ri, how's it going?”
He looked a bit nervous when he came in. “How, how did you sleep?” he asked.
“Really well. Had the best dream. How about you?”
We chit chatted, and I noticed he relaxed. We decided we'd get up and have breakfast. “I'll wait for you to leave,” I said.
“Why?”
“Well, I sleep naked.”
“So? We're, we're both boys.”
I shrugged, even though inside I was kind of elated. When I got up, I exaggerated my stretching so he could get a nice view. I tousled his hair before going to grab my bathrobe. I stood facing him while putting it on. I could tell he was enjoying the view which gave me hope.
During the day we hung out, did some chores, and a couple of times we wrestled. Once I was pretty sure he popped a boner. He rolled over immediately once I let him go.

The next morning I wondered if I would get a return visit. I was halfway hard when I heard him at the door again. I went back into sleep mood. I had the sheet still covering me this time. Soon I felt his hand on my growing cock through the fabric. “Ah, Maggie. You came back for more cock.”
I rubbed his earlobe between my fingers.
“Go on, baby. Get that meat.”
I felt him move the sheet off me, and he didn't waste any time before going down on me again. As he got started, I began rubbing his butt through his pajamas again. He surprised me by lowering his clothing and bearing his ass for me.
“You like that ass being fingered, don't ya baby?” I happily slid my middle finger into his cherry and began slowing moving it back and forth.
He was working my dick well. I grabbed the bottle of lube I had put beneath my pillow, and I got three of my fingers ready. I imagine he must've seen me doing this, but he didn't stop. I kept my eyes closed like I was still asleep, though.
I could work his hole more now, and it didn't take long before I had three fingers inside his butt.
Soon I said: “It looks like your ass is liking those fingers, baby. Maybe it needs my dick in there.”
He didn't stop sucking and didn't change position, so I decided to just leave things as they were.
A little while later I did tell him to come suck on my nipple, and he did do that. I could smell his kid's shampoo in his hair. For some reason that was a turn-on for me.
When he returned to my dick, I used my hand to guide him down a bit more. He coughed a couple of times, but soon enough he was doing it on his own. “You're such a great cocksucker, babe. I just love how you swallow my meat.”
A bit later I kind of pivoted onto my side toward him. I took hold of his neck and started using my hips to face fuck him. Feeling how small his neck felt beneath my hand compared to his mom's just made it even hotter. As I began picking up the pace, I felt him grab onto my butt for balance.
“Yes! Take that dick, Maggie!” I figured it was safe enough to open my eyes more. Goddamn what a sight! Seeing his red lips sliding up and down my thick shaft drove me wild. My large hand next to his small head was hot. The look of pleasure on his face was even better. It was awesome to have visual confirmation of how much he enjoyed blowing me.
I needed to see that ass better so I moved my body further away from him. “Join me on the bed, Maggie. I need that ass.”
He immediately climbed onto the bed.
“Get on your knees, baby.”
He didn't stop sucking me as he got into this position. I noticed his red and black tartan pajama bottoms and his white briefs bunched around his ankles. I used both hands to spread his butt-cheeks apart and gazed at his sweet hole. Fuck I wanted to be inside there so badly! Watching my finger slide into his butt really fired me up.
He sped up in response, and I could hear him trying to take more of my rod into his mouth.
“Yes, baby! Take that fucking cock deep.”
Once I had three fingers inside him, he had to take a breather from sucking me. He seemed to arch his butt up into the air more.
“Your ass is fucking amazing.”
I closed my eyes when he went to suck on my balls so our eyes wouldn't meet. I didn't want him freaked out. I began thinking of how I was going to get things to the next level because I desperately needed to fuck him.
My climax was starting to build, so took hold of his head and started guiding him more aggressively. I bent my legs so I could use my hips more and began humping his mouth. He responded like he was on fire, and a few seconds later I could feel his dick twitching from inside. I wanted to grab his stiffy, but that would be too obvious for him at this point.
It didn't take long before he was back to blowing me steadily, and soon I was unloading in his throat. He initially coughed but kept swallowing and sucking. “That's right, Maggie. Milk my cock. Get all that jizz.”
He still sucked me slowly for a bit after I let go of his head and pulled my fingers from his butt. 
I watched as he moved off the bed and pulled his clothing up. I closed my eyes quickly as he turned toward me. When I felt safe, I cracked them a bit and could see him staring at my dick. Finally he left the room.
This time it took longer before he returned to my room and was knocking. I didn't bother covering up. He had a hard time not looking at my groin while we were talking. After a few minutes, I noticed him readjusting his dick through his pajamas.
He was sitting next to me, and I placed my hand on his knee and just left it there. I saw his wood twitch, and his face turned a bit red.
“You know, you're a good-looking kid,” I said. He blushed and I used my thumb to move over his lips. “I bet you're a great kisser.”
“Really?”
My dick was starting to swell. I sat up and leaned forward. He looked scared and desirous.
“Your eyes are so blue,” I noted.
I moved my head in closer. When he didn't move, I softly kissed him on the cheek. He licked his lips nervously, and I kissed him lightly on the nose. I looked into his eyes and could see the fire inside him as well as the anxiety. “Do you want more?” I asked.
He nodded, and I kissed him gently on the lips. I moved my hand up to his thigh, and I could feel his heat. This time I took his bottom lip between both of mine and lightly sucked on it. Without breaking the kiss, I took hold of his hand and moved it to my now rock-hard meat. As he took hold of my dick, I slowly slid my tongue into his mouth and begin kissing him more passionately. 
He took firm grip of my meat and relaxed into our kiss more. I moved my hand to his groin and rubbed his hard-on through his pajamas.
When I finally broke the kiss. I reached down and took hold of his shirt. As I began pulling it slowly up his body, he quickly raised his arms so I could pull it off. I smiled at him as I let my fingertips slowly explore his shoulders, slide down his arms, move to his belly, and slowly go up his chest.
“You and I are going to do something very special today,” I said as I guided him onto his back. I softly sucked on his neck which made him moan and writhe. Then I moved to one of his nipples and sucked on it.
Next I sat up. I reached down and slowly undid the ties on his pajama bottoms. We maintained eye contact the whole time. Then I took hold of the waistband and slowly pulled them down his thin legs.
My cock was throbbing with anticipation and lust. I rubbed his wood through his briefs. “You ready to be as naked as I am? You ready to move our relationship to a higher level?” I asked.
He nodded briskly.
I smiled as I took hold of the elastic band of the underwear at both of his hips. Then I languidly slid those down his body. His dick sprung straight out as soon as it was free. After I tossed his briefs onto the floor. I gazed at his nude young body. I put my hands on his ankles and slowly slid them up his legs, his stomach, and his chest. Once I was over him completely, I lowered my head to his, and I kissed him harder.
I ground against him as we kissed, and after a bit I held onto him and rolled onto my back. As soon as he was on top of me, I slid my hands down his smooth back and took hold of his ass. I kneaded those perfect cheeks as we tongue kissed.
After we kissed a bit longer, I moved his head backward some. Looking into his eyes, I said: “Today you're going to become a man and my very special boy. You ready for that?”
He nodded briskly and replied: “Yes, Max!”
“Good. I've wanted to get closer to you for a long time. There's no way of getting closer to someone than being inside them. I want to be deep inside you, Riley.”
“What does that mean 'be inside' me?”
I swept some of his blonde hair away from his forehead. “I'm going to put my dick inside you, Ri. I want to get as deep as possible. Since you don't have a vagina, that means I'm going to put it in your butt. I want to make love to you in this very special way.”
I squeezed his butt-cheeks as I kissed him again. I rolled so that we were on our side, and I draped my muscular leg over his tiny hip. “So what do you say, Riley? Will you let me become one with you?”
“So, it's like you're going to have sex with me like you do my mom.”
“Yes, only more slowly and gently as this is your first time. I want this to be a special moment for you, well, for us both.”
I could tell he wanted it, but he was also nervous.
“Will it just be this one time?” he asked.
“If that's all you want, I'll respect that. I'm hoping, though, that this will just be the first of many times.”
“Once we do this, there's no turning back is there?”
“I'm not sure what you mean, but our relationship will be very different. Very special and close.”
“I want that,” he said.
I kissed him gently. “I want that, too, son.” I had never called him that, and it surprised us both.
“Okay then . . . Dad,” he said. I felt him moving so relaxed my touch on him. He turned over onto his other side so his back was facing me.
I ran my hand up and down his body getting lost in how sexy it felt to me now. I put some lube on my finger and inserted it into his butt first. Then I put a large amount on my cock and moved into position. 
I could feel my pulse in my ears my heart was pounding so hard. I placed the tip of my dick against the sacred entrance to his hole and paused. Since he didn't move or say anything, I took that as the final green light, and I entered him.
As my meat moved into his hole, I was feeling things I never had before. “Oh my fucking gawd, Riley! You feel fucking amazing!”
I watched his face as I slowly advanced my rod. The previous ass play seemed to have helped because he was able to quickly relax as more of my wood slid into him. When I needed to let it just stay in place for a bit, I reached over his hip and found his hard-on. I slowly stroked him while I nibbled on his ear.
“I'm getting inside you, boy. I can't believe how awesome you are.” Soon I started moving my hips back and forth a little. “How does that cock feel inside you Ri?”
“Good,” he slightly grunted.
“You can push backwards any time you want more, too,” I said. I smiled when I felt him do just that.
I slid my hand up his body until I found a nipple and began playing with that.
“I want to see how it feels buried all the way inside you, Ri. Do you want my whole cock inside you, baby?”
“Yes,” he moaned, and I slid more of it in.
“My cock loves you so much, and I love you, too.” I started humping him a bit more now. “Take me all the way, baby.” I moved my hand to his chin and turned his head toward me. I kissed him passionately as I slid more of my dick in.
I couldn't believe how fucking fantastic this felt. “Oh, Riley. Do you want that cock, baby? Do you want it deep inside you?”
“Yes, Max! Give it to me.”
I pushed it in deeper. “I love your lips. I love your lips on mine, and I love how they feel on my big cock.”
“So you weren't dreaming.”
“I was awake, but it was like a dream for sure. You're an awesome cocksucker, buddy. I couldn't wait until you woke up.”
He relaxed much more, and I was able to bury more of my meat. I moved my hand back down to his crotch and stroked his small dick.
“How long have you wanted my cock, Ri?”
I pushed more into him as I began sliding it back and forth faster.
“Go on, you can tell me. Be honest.”
“For . . . for a while I've been curious.”
“And now you've got it,” I said.
I wrapped my arms around his chest as I continued humping his butt. When I couldn't take it anymore, I whispered into his ear: “It's time, baby. I'm going to give you all my meat.”
“Yes . . . Daddy,” he said.
I rolled with him so that he was on his stomach. While holding him in my embrace, I pushed my dick forward and kept going until my body was pressed into his.
“I'm all the way inside you now, Riley. You're my special boy.”
“And you're my special man.”
We kissed again while I rested against his hot, young, small body. My knees were on the bed as I began slowly moving my hips.
“Our bodies are fused together, little man. Me and my cock need you.”
“I want it, baby,” he said in a way that surprised me.
“We just need to make sure we don't call each other that in front of your mother,” I said while chuckling.
Soon I was ready to go a little harder, so I rested on my forearms to take the weight off him. I began pulling back a bit farther before each thrust. I saw him grab fistfuls of the sheets, and he moaned loudly. “Oh gawd!” he cried out.
That egged me on, and soon I was doing deep thrusts.
A little bit later he cried out: “Yes, Max! Fuck me!” Just like his mother. I grabbed a pillow and slid it under his hips. This gave me a better angle to work. I moved onto my hands and started pounding him. Soon our bodies were slapping together, and the bed was creaking beneath us.
“That cock feel good, boy?”
“Fuck yes! Give it to me!”
His moaning grew louder, and I picked up speed in response. Then he yelled out. I felt his ass muscles gripping me, and I could feel his dick twitching from inside again. I reached under him and took hold of his dick which made it twitch more. I felt a little wetness, and when I looked at my hand I could see a small amount of clear fluid. I licked it off my fingers. It didn't have much flavor.
When his hole relaxed again, I returned to pounding him. Every so often I would stop and just leave my buried cock inside him. Sometimes I would make small circular motions with my hips before picking up speed once again.
I didn't last much longer, and even though I had cum recently, my dick was unloading like crazy because of his tight ass.
Once my meat was finished unloading I pulled out and collapsed next to him. He moved the pillow and readjusted so he was cuddling me. We kissed again, but more gently this time. “You're no longer a virgin. I feel honored you gave it to me.”
“I'm your little man.”
“Yes you are, Ri.”
He lay down next to me, and I turned onto my side facing him. I used my fingertips to explore his body once again. His smoothness and silky skin was so fucking hot. He was getting a bit of muscle development, and it looked like maybe he was just starting to grow a six-pack.
Hunger hit us both, and we decided it was time for breakfast. I put on my bathrobe, and he pulled on his pajama bottoms before we went to the kitchen. After eating, we sat together on the couch and turned on the TV. A few minutes later, I heard him ask “Can. . . can I see you naked?”
“Go ahead,” I said and watched as he undid my robe and pulled the fabric aside. He ran his small hand over my chest and abs. 
“You have a lot of muscles.”
“It's one of the things your mother loves about me.”
“She often says you're sexy,” he said.
I smiled at him. “And what do you think?”
He blushed boldly before answering “I agree with her.”
“Yeah, you find me sexy little man?” I rubbed his chin.
His hand moved to my soft meat, and I leaned over and kissed him. While we watched TV, his fingers enjoyed playing with my black bush and feeling the hair on my muscular legs. I ran my fingers through his blonde hair on his head. It was so pleasurable having this uninhibited moment with him.

After a while, we needed to run some errands, so we got dressed. We ate lunch out. When we got home and put the groceries and other stuff away before returning to the couch.
When the first program ended, he got up and stood in front of me. I watched his hands go to the strings on my sweatpants. He undid them, took hold of them and started pulling them downward. I lifted up my hips to make it easier for him. As soon as they were off, he returned for my boxers.
I smiled at him as I watched him get onto his knees. I spread my legs wider as he moved forward, and soon his lips were on my sac. As soon as my dick started rising, he licked upward from the base to the tip. Once he got to the head, he opened his mouth and went down on me. I pulled my shirt off as he brought my cock back to life.
“You're needing a lot of meat today,” I said with a big grin.
He nodded while he continued working my rod. Soon he stopped and stood up.
“Why'd you quit?” I asked.
“I . . . I want it . . . I want it in my butt.”
I stood up and took him gently by the chin. “I will happily fuck you again my boy. Take me to your room so I can do you on your bed this time.”
He took me by the hand, and I followed him to his room. Once he was at his bed, I stopped him. I pulled his shirt off his small body and bent down and tongue kissed him. I looked at his kid decorations and his Spider-Man blanket, and for some unknown reason it made my dick twitch.
I guided him to lie on his bed on his back. I undid his jeans and took hold of them and his briefs and pulled them both off his stick-like legs in a slow manner. I spread his legs apart and rubbed his little nut sac. It was tight against his body as his little hard-on twitched.
I smiled at him and moved between his legs. He looked surprised when he realized what I was about to do. I noticed his back arch as soon as I took him into my mouth and began sucking on him. His small fingers took handfuls of my black hair as I worked his peter.
After I blew him for a bit, I kissed up his skinny torso. He wrapped his bare legs around me as I gently sucked and kissed his neck. I had to remember to be careful to not give him a hickey!
When I moved to his lips, I felt one of his hands grab my cock and begin stroking it.
“You addicted to my cock, little man?”
“I want it!”
I smiled. “Yeah? Where do you want it, son?”
“In my butt! Fuck me, Daddy!”
I grabbed his legs and shoved them up by his head. I took hold of them with one hand, and I gripped my cock with the other and guided it to his hole. My eyes closed with ecstasy as soon as I entered him. He was stretched out enough I didn't have to stop too often, but it still was a slow process. “Watch my cock disappear into your sweet ass, Ri.”
“It's so big, Max!” He took a breath. “I want it!”
I went ahead and started pushing it in faster. It was so hot to be able to look down and see his hole swallowing my meat. I thoroughly enjoyed watching the expressions on his face as my dick filled his insides. Soon I was leaning down and kissing him while I was fucking him.
After I was done pounding his hole, I collapsed next to him and was practically gasping for air. We cuddled naked and ended up falling asleep. I was glad we woke up with plenty of time to get showered. He was happy when I told him to join me in the shower. We made out while the hot water rinsed our sweat from our bodies.
That night at dinner, Riley asked his mom if it was okay if he started calling me Dad. She was surprised and looked thrilled. She said it was up to him and me, and I announced I was fine with that.
Later that night I tucked him into bed. We lightly French kissed, and he gave my dick a gentle squeeze through my sweats.

In the morning I awoke as the bed moved. “Good morning!” Riley said as he pulled back the blanket and sheets.
“Umm, good morning, little man.” I noticed he was naked as he moved between my legs. I spread them as he took my balls in his mouth. “What a fucking lovely way to wake up,” I said as he began sucking my dick.
“I want to taste that salty stuff again,” he said.
Life was turning out to be fucking wonderful.
