I enjoy hanging with my mom's boyfriend Lou. He's super friendly, really fun, and kind of affectionate. I often cuddle with him at night on the couch. Since I turned 12, I've noticed that I've been feeling more interested in him and other dudes. I especially am curious about noticeable bulges. Lou's is definitely hard to miss, especially when he wears basketball shorts. I'm pretty sure I've caught him with a hard-on a few times, too. He doesn't seem to care to hide it.
I really enjoy cuddling with him when he's shirtless. He has nice chest muscles and what Mom calls six-pack abs. He has a light amount of dark brown hair on his chest, and a line of it runs from his belly button down into his shorts. It matches the hair on his head. He also has green eyes. I love resting my head against his chest, hearing his breathing and heartbeat, and being able to look down at his bulge.
Last night he was playing with my hair, and I rested my hand on his thigh. I so badly wanted to move my hand up higher, especially when I'm pretty sure his dick was kind of growing. Mom asked him to go help her with something, I didn't get to see if he was going to get harder. When he first got up, I saw his hand adjusting his groin area, and he smiled at me.
Today I was surprised when Mom announced Lou was taking me to the place with private hot tubs. I really like going there but have never gone with him.
While he was driving, I was pretty sure I saw him adjust a stiffie a couple of times. 
Once we got into our private tub room. I grabbed my trunks and headed toward the bathroom to change. 
“What you doing?” he asked me while removing his shirt.
“Changing into my trunks.”
“Nonsense. Come on over here. We're both men.”
I sat down on the bench and took my shoes and sock off. I couldn't help but notice that he was standing almost in front of me as he removed his shorts and boxer briefs. I also couldn't stop myself from practically staring at his big dick and balls as soon as I saw them. He had a thick brown bush of hair, and I noticed that line from his belly led straight to this bush.
“You like what you see?” he asked with a big grin.
“Hmm? What? Oh, I wasn't looking.”
He moved in closer to me, and I had to swallow my saliva. I felt his rough fingers gently grip my chin, and he made me look up at him. His dick was right in front of my face. His green eyes seemed darker. “I know you were looking. I know you look down there a lot, and I'm okay with that.”
I swallowed again and could feel the heat in my face as I blushed strongly.
“Your mom can't give me as much sex as I need. So you and I are going to have some fun. Since you're family, it ain't cheating.”
My heart was pounding. I glanced toward his groin real quickly and noticed his thing was growing stiff.
“You like seeing me naked, Teo?” he asked.
I wasn't thinking, and I caught myself nodding my head.
He grinned even more. “Good. You're pretty hot, too. You make my cock hard.”
As I looked at his groin again and confirmed his thick meat was standing straight out from his body, he moved and his dick slid across my face. I felt a dampness, and so I put my fingers there.
“Put your fingers in your mouth now.”
I did as he said and tasted a mild saltiness. When I removed my fingers, the tip of his hard-on was rubbing on my lips. “Go on,” he said softly and smiled at me again. I felt a fire spread inside me, and I opened my mouth. As his meat slid into my mouth, I began sucking. He slowly moved it back and forth in my mouth, and I thought I might pass out. There was something about doing this that drove me wild. At this point I also noticed my own dick was stiff.
As he began moving faster, I felt one of his hands on my head. His dick went deeper into my mouth. I found myself grabbing onto the back of his muscular legs as he fed me his rod. I glanced upward to see his expression. It was much more intense now. He had me suck on his low-hanging balls. I gazed into his green eyes as I did this.
“My cock sure does belong in your mouth.”
In response I returned to sucking him. I tried to take more of his meat and started going faster.
After a bit he pulled back. I saw a long string of saliva spread from my lips with the other end attached to his meat. I wiped it with the back of my hand.
“My cock taste good, Teo?”
I nodded silently.
“Good. I'm looking forward to it being in your mouth often.”
My heart was pounding in my chest.
He had me stand up. I raised my arms as I felt him pulling my shirt off. He lay it gently on the bench, and I swallowed hard again. I couldn't believe this was happening. His fingertips lightly explored the skin on my shoulders and chest. He rubbed my nipples which sent thrills through me. Soon his hands were on my shorts. I could feel my pulse in my ears, and I know my dick twitched when I felt his fingers on my skin.
He slowly slid my trunks and briefs down my legs a bit before letting them loose. Then I felt him take hold of my much smaller wood. He slowly stroked me as he bent down. His lips lightly touched mine, and I found my mouth opening as we began to kiss. I reached out and grabbed his cock, too, as our tongues met.
After we gently tongue kissed, he picked up a small bottle from his bag and grabbed my underwear. He took me by the hand, and we walked toward an area with mats near the hot tub. I watched him turn the music up in the room and wondered why he was doing that.
When he returned he guided me to lie down. I was on my back, and his body covered mine. Our dicks rubbed together as we kissed some more. Soon his lips were gently sucking on my neck. My toes curled, and electricity swept through me.
He whispered into my ear: “Do you want my cock, Teo?”
“Yes,” I almost hissed in ecstasy.
“You're about to become my very special friend, and I'm going to make you a man.”
He began sucking on my nipples and slowly kissing and licking downward. As his mouth approached my groin, my legs spread instinctively. When I felt his tongue slowly slide from my balls up my hard meat, I thought I might pass out. 
He sucked my dick slowly for a few moments before continuing to work his way down my legs. After sucking on my big toe. I watched him take the bottle and squirt some clear stuff onto his hand. He stroked his cock with the gel while smiling at me.
I still hadn't figured out what was going to happen, but I was having enough fun I didn't care. He had me roll over. When I did he pushed my legs apart, and I felt his lips on my skin again. Soon he was at my butt. I felt him pull apart my cheeks. “It looks like heaven,” he said right before he began licking my butthole.
As he worked my hole, I felt my body adjusting so that my butt rose higher into the air. When this happened, I felt what I think was a finger slide into me. “We need to get this nice and relaxed.” I tried to force it to loosen up, especially after another finger slid into me. His other hand took hold of my dick and slowly stroked me as the fingers stretched and relaxed my bottom.
After removing his fingers, he moved behind me. He bent down and kissed my cheek and ear before saying, “And now I'm going to make you mine, baby. I'm going to fuck your tight, sweet ass, Teo. It may hurt at first, but you will come to love it.” I felt him readjusting, and within seconds I felt the first part of his cock enter me.
My eyes widened in surprise at the feeling as more of his dick slid into me. 
“We're gonna spend a few hours fucking, Teo. I want that ass used to having my cock buried inside it. You're going to be sucking and getting fucked by my big dick a lot now, buddy.” My fingers clawed at the mats beneath me as his meat invaded me deeper. 
I was breathing through my mouth now. I saw him place my white briefs in front of my face. “If you need to make a lot of noise, just stuff your mouth with these first.”
He sank more of his cock into my hole, and I felt a mixture of extreme pleasure as well as fire flash throughout my body. I grabbed my underwear and stuffed it into my mouth as I made a loud sound I'm not sure I can describe.
“You're doing amazing just like I thought you would. We're going to have so much fun, Teo.” He began moving his meat back and forth in my butt. I forced my hole to relax more, and as he began to pick up speed he also began plunging his dick deeper with each forward thrust.
Soon he rested more of his body against mine. It was amazing to feel his hot skin against mine. He pulled the briefs out of my mouth and kissed me hard. “You like that cock, baby?”
“Yes,” I croaked, even though I wasn't sure that was entirely true.
“My cock sure loves you. It wants you badly. It wants to be deep inside you. You're going to take every one of those eight inches aren't you, baby?”
“Yes, Lou! Yes!” I said as he picked up speed a bit more. We kissed hard and suddenly more fire swept up from my hole as more of his meat entered me.
“Take a couple of deep breaths, Teo. You got this.”
I did as he said, and I felt him go deeper. Soon I could feel the hairs of his bush against my skin. I felt his arms slide underneath mine to support my chest, and he was guiding me into a kneeling position. Soon I was sitting in his lap.
“Yes, Teo! Every. Fucking. Inch.”
He kissed my cheek and neck while one hand rubbed one of my nipples and the other was rubbing against my now-soft dick.
“Tell me you want my big, beautiful cock, baby,” he whispered.
“I want it, Lou! I want your big, beautiful cock!” I almost shouted. I wasn't sure it was convincing, but I wasn't completely lying either.
Soon he was moving me back into a flat position. He pulled his meat out quite a bit and shoved it back in making me almost yell out. He shoved the briefs back in my mouth. He did this maneuver again, and I found it helpful to let myself moan and make whatever noise I needed.
“Your mouth and ass are all mine now, Teo.”
Shortly after this he was fucking me so hard I could hear a slapping noise from how our bodies hit together. 
He pulled the briefs out of my mouth. “I want to hear your moans, baby.”
He slowed down now, and when he did his forward thrust I could feel his body moving slightly forward too, like he was trying to go even deeper.
I let myself moan, and I heard him reply, “Oh fuck yes!”
He continued humping my butt. He would change speed and depth so that sometimes he was doing short thrusts and other times it was slow and deep. Soon I felt pressure building up in my dick. It felt really rough at one point before suddenly releasing. I gasped and could feel something inside me twitching. 
His hand moved beneath me and grabbed my dick for a bit. “You just had your first orgasm, although it's still dry.”
I didn't know what that meant but holy fucking shit was it amazing!
His pounding my hole felt even better as the effects of the orgasm continued for a while. Soon he was frozen in position while his dick twitched inside me. He lay pressed against me for a few minutes before rolling off and lying next to me. He was breathing hard, and we were both covered in sweat. He pulled me over to him, and I lay my head against his chest. This time cuddling against him was so different.
After a while, he said “That was fucking amazing. Let's hit the hot tub.”
As we got up, I headed to get my trunks. 
“Where are you going?” he asked.
“For my trunks.”
“Dude, we ain't wearing clothes until it's time to leave.” He held out his hand for me. I went over, took his hand, and joined him to get into the Jacuzzi. I noticed I was walking funny. I also felt something wet going down my leg. I wiped it with my fingers and saw some white stuff.
“What is this?” I asked showing Lou my fingers.
“That's my . . . special milk. My jizz. Taste it.”
I licked it and found that it was slightly sweet and salty.
“Later I'm going to have you suck my dick until my cock shoots that stuff down your throat.”
We got into the soothing hot water. It seemed to help my hole feel less sore, too. I swam around in the big tub. Sometimes Lou would pull me over, and I'd sit in his lap while we kissed. I kind of enjoying making out with him. It was really fun to be in the tub naked, too.
At some point when we were making out again, he began rubbing my groin. My dick perked up, and I liked feeling him playing with my dick. Soon I reached down and felt his hard meat.  He positioned me so that my legs were on either side of him. We tongue kissed as his hand moved his cock to my ass again. He had me move up so that he could get to my hole.
I tensed a bit as I felt him enter me again. My hole still stung from the last time. His hands grabbed my hips and pushed downward, and I figured out he wanted me to sit on his dick. I started sitting back down. He held onto his rod as my butt slowly swallowed his stiff meat.
“That's right, Teo. Take that fucking cock!”
I bit my lip as he got deeper. It didn't hurt like last time, but it still wasn't totally enjoyable either. Soon he began moving his hips so that his dick slid back and forth inside me. This began to make things feel better, and soon I found that I started to move myself up and down as well.
“Yes, boy! You want that dick badly,” he said.
No, I didn't want it that much, but things were starting to feel good. I started moving up and down faster and this brought out a moan from my lips. He pushed up, and I moved down and was finally sitting completely on his legs. I put my arms around his neck as he took hold of my butt cheeks and guided me up and down.
“Feel my cock deep inside you, baby.” He took hold of my hard-on again and rubbed the head of my cock. I moaned out loud.
I rode him like this for what seemed like quite a while. Soon he asked, “You ready for it to get a little rougher?”
I had no idea idea what he meant, but I was feeling so amazing I just nodded my head. He got up and moved to one of the sides of the hot tub. He carried me. Once we got there, he lifted me off his cock. He set me down on the rim of the tub. He had me move so that my chest and stomach were on the floor, but my legs and part of my butt were in the water. 
He put some more of that gel on his cock and got behind me. This time there was only a little sting as he entered me. He grabbed the area between my shoulders and neck, and I felt him shove the rest of his cock into me. “Unhh!” I said. I kind of bit my hand as he began slowly pulling his dick backward. He shoved it back in again. 
After doing this another time he began moving faster, and soon he was yanking me backwards as he shoved his dick deep. The pain was quickly being replaced by pressure, and soon I heard myself say “Fuck me, Lou! Ohmigawd, yes!”
Every so often he would bury his cock and leave it sit for a bit, or he'd move his hips in almost what seemed like a circle. At one point, he grabbed my long blonde hair and pulled it back. “Your fucking ass is mine, ain't that right, boy?”
“Yes! It's all yours!”
He continued fucking me hard like this for a little longer. Then he suddenly pulled out, and I saw him getting out of the tub. He roughly pulled me all the way onto the floor and flipped me over onto my back. I opened my mouth because I thought he wanted me to suck on him again, but he grabbed my legs and pulled me around so he was basically between them. He shoved my legs toward my head so that my ass went high into the air.
I watched as he got into place and began feeding his dick into my hole again. “I want you to watch my cock disappear inside you.”
I stared at his thick meat as it sank into my hole. It was weird to feel it moving inside me while I could also see it. Soon his brown bush was touching my skin. I watched as he returned to humping my hole. Somehow it made it even hotter to see all this.
Soon he put my legs around him, and I gripped him with my feet. His mouth crashed against mine, and we kissed hard as he fucked me. I lost all sense of time and anything else. There was just these amazing jolts of thrill that ran through me as his body slammed against mine.
After a while he stopped suddenly again. I opened my eyes and saw him removing his dick from my hole. He grabbed a towel and wiped it off. Once again he grabbed me by the hair, and he yanked my head toward his groin.
As soon as it was within reach, I opened my mouth and took his meat and started sucking on it. “You're going to swallow my cum this time.”
I wasn't sure if that was different than jizz but whatever! I sucked him eagerly. As he grabbed my head and guided it back and forth, I grabbed onto his tight ass cheeks for support. A few times he shoved his cock in a bit too far, and I gagged. It didn't seem to affect him, and I just focused on making him happy.
Soon I heard “Get ready to swallow! Fuck!” Then I started coughing as salty liquid shot in my mouth. I swallowed as he held my head in place. He let me go when his dick stopped twitching as often. I continued sucking, though, for a bit.
When he pulled his dick out of my mouth, he stretched out over me. We kissed gently this time. He rubbed his dick against mine. When he lay down, he guided my head down toward his groin, so I voluntarily moved in and continued sucking him but slowly. He played with my cock and balls as I worked his meat. He also had me spend some time on his balls. Every so often, I got a small amount of more jizz, and I licked it up.
We went back into the Jacuzzi for a while. Occasionally we made out. When we got out, we picked up our towels and dried off. I went back to the bench to get my clothes. I felt him there soon after. I looked up and was staring at his hard dick.
“We have time for another fuck,” he said. He took me by the hand, and we walked over to the mats again. We kissed while standing up. He sank to his knees so we could kiss more easily. Soon I felt his hand on my dick. “You're hard. You want this.”
I watched as he put more gel on his fingers. Soon he was fingering my ass while he sucked on my small dick. He guided me to the ground and had me get on my belly. I watched him rub the gel on his meat and get into position on top of me again. This time he entered me much more easily, and it didn't take as long before our bodies were touching again.
He began slowly humping me. “This one I'm going to make this one last,” he said.
It definitely felt different as he moved differently. There were times when I could feel my ass raising into the air as he worked my hole. At one point he moved me onto my knees. His fingers gripped my hips and butt as his meat moved back and forth.
After a while of that and a couple of position changes, I had that dry orgasm thing again. This time it seemed even more intense.
“See? Your ass loves my cock. You want my cock deep inside you, baby.”
I couldn't argue even if I wanted to. This orgasm thing was amazing! “Yes! Give me your cock, Lou!” I replied.
He pulled out and had me flip over. I immediately pulled my legs back this time because I knew what was going on. He smiled as he returned his thick meat into my hole, and we kissed deeply. I locked my legs around his back again. Sometimes I dug my heels into his butt cheeks.
“You want me. Every single fucking inch.”
“Yes, baby! Ohmigawd give it to me!” He pulled his cock backward so far it actually popped out. He replaced the head and shoved the his whole length into me. “YES!” I cried out. He switched in between doing rapid and slow thrusts which drove me wild.
Soon he wrapped me in his arms, and he changed positions. He maneuvered us so that I was basically in his lap. My legs went behind him. “I want to see you fuck yourself with my dick.”
I moved my legs so that I could raise and lower my body, and I began riding him. At first it was slow, but I needed to move faster, and I just let my body do what it wanted. My fingers dug into his shoulders as almost bounced on his meat.
He kissed me hard every so often. We couldn't really keep kissing because of the way I was moving.
“YES! FUCK!” he said as I picked up speed. Soon he stopped me. At first I was confused, but then I could feel his dick twitching inside me. This time we tongue kissed more gently before it was finally time to separate our bodies.
As we showered together, I enjoyed exploring his body more with my hands and eyes. He had me kind of run around the room to help me walk better because I was walking funny still. 
We got dressed and headed home. As we drove, we talked about how this was our special secret. He didn't want my mom to be jealous. That made sense to me. We held hands as he drove, and that made it feel even more awesome.
I can't wait to see how things develop between us!
