I've been viewing my dad differently ever since we went to the gym a few months ago. I mean I've always been interested in his body. He has a crooked smile which makes me feel a bit warm inside. I like looking at his muscular chest and his abs. He says he's proud that he has six-pack abs while in his 30s.
He usually works out by himself, but this time he took me with him. It was fun working out with him and seeing the big weights he can use. But what really got me was when we were in the locker room. We stripped out of our clothes and showered together. 
They have private showers, and I was thinking of going into my own when he suggested I join him since there are a bunch of strangers here. I couldn't help staring at his dick and the bush of dark brown hair he had right above it. I noticed his balls were hairy, too.
As I soaped up, I admired his whole body. I'm 11, and think this is the first time I felt someone looked sexy like what I've heard teens and adults say. I also noticed my dick was getting hard, so I had to stop looking at Dad.
When he moved by me to grab his towel, he brushed up against me, and it felt like electricity was going through me. I'm pretty sure his penis touched me, and I just wanted to put it in my mouth.
I was tempted to do it again another time when we went to a public pool. We were changing in the same space. I was sitting on the bench. His dick was swinging right in front of me as he moved. 
With all of these weird thoughts, I started what some boys call jacking off. I don't shoot any of that white stuff I've seen in pictures, though. In sex ed they said that probably won't happen until someone is 12-14. Still, it does feel good.
At my best friend's house, we often look at his brother's porn mags. I like to imagine I'm the woman and Dad is the dude.
A couple of times I've also played with myself while listening to Mom and Dad doing it. He likes when Mom moans. I've heard him almost begging for “head” or a “blowjob” a few times. I guess Mom doesn't like to do that as much. One time I heard her say “I don't like it when you come in my mouth.”
I had to look all those things up. I found out that white stuff is also called cum. 
Dad and I have been building a treehouse. Because of the heat, he often wears only shorts. When I'm on the ground or below him on the ladder, I discovered he often doesn't wear underwear either. 

Dad had a road trip and invited me to come along since we weren't having school. It was really fun getting to spend even more time with him. The first morning I woke up before him, and there was a big lump in the sheet. I moved my head under the covering and saw his hard dick! It was sticking out of his boxers. I couldn't believe it. I so badly wanted to grab it or suck on him. Unfortunately, he woke up before I could gather my courage.
I joined him in the bathroom as he peed. We played sword fighting with our streams, and I enjoyed staring at his stiff meat until he tucked it back into his underwear.
Two nights later was when things really changed. We had gone to bed, and I woke up because of flashing lights like when you watch TV in a dark room. I looked over, and Dad was kind of sitting up. In one hand he had his iPad. I could see he had his earbuds in. Motion caught my attention, and I saw his other hand was rubbing his hard dick. Dad was jerking off!
I felt hypnotized by seeing his hand moving up and down his cock. He was going slowly, so I figured he had just started.
I couldn't help myself. I was pretty close to him already so I was within reach. I put my hand out and gripped the bottom part of his dick when his hand was up by the head.
I started moving my hand even though his had frozen. 
“Max!”
“Please, Daddy,” I said in almost a begging tone. I kept moving my hand up and down and looked up at him. He look startled but also curious. I bumped my hand into his a couple of times, and he let go of his dick.
He relaxed against the pillow that was behind his shoulders. I saw him put the iPad down and close his eyes.
I moved in closer. He moved the arm that was under me, and I felt his hand resting on my bare back. This gave me the courage I needed. I opened my mouth and went down on him.
I felt his body go rigid. I glanced up at him while I continued sucking on his salty flesh. He was biting his lower lip. I went up and down a few times before he said: “I sure hope you're going to finish me off.”
“I want to taste your cum, Daddy.”
He gently ran a few of his fingers against my cheek before putting his hand on the top of my head and pushing me down more. I started trying to take more of his big dick into my mouth.
“We shouldn't be doing this,” he said, but he didn't do anything to stop me. Soon his hands were shoving his boxers down. I moved and watched him quickly yank them off. He tossed them onto the table where we'd be eating breakfast. As soon as he was naked, he spread his legs apart. He guided my head to his balls, and I started sucking on them.
“This is our little secret, OK?”
I nodded my head before quickly saying “Promise” and returning to blowing him.
He seemed to relax, and I began sucking him more eagerly. A few moments later I felt him pushing my pajama bottoms and briefs down. He pulled them down until they were at my knees. He rubbed my butt cheeks gently before moving his hand so he could feel my hard-on.
As he began stroking me, I picked up speed on sucking him. His hand began guiding me, and I followed that pace and struggled to take more of him into my throat. I gagged a few times but kept going.
A bit later he had both of his hands on my head, so I figured he must be getting close. I sped up, and sure enough he soon said “Fuck!” and I coughed as his thick, salty load blasted my throat. I started swallowing right away so I wouldn't have to move my head. It might be crazy, but I was hoping he would want this from me again.
“Oh, Max!” he said as I continued swallowing and moving my mouth up and down to get more of his yummy cum.
When his dick started softening, I finally let him go.
“Holy shit that was incredible, Max! Thank you so much. I needed that more than I realized.” He kissed me on the forehead. I wanted his tongue in my mouth. I pulled my clothing off so I was naked like him and cuddled up against him once he readjusted in bed so he was lying flat.

We got home the next day. Nothing was said even though I really wanted more. We finished the treehouse and went to the store to pick up some stuff for the inside, and some lights I wanted.
On the way back to the house, I asked Daddy if we could spend some time naked. We were driving by a park, and he went ahead and pulled into the parking lot.
“Max, are you asking because you enjoy being naked, or because you want . . . more of what happened the other night?”
I blushed.
“You can be honest.”
“Well, I want more of that.”
He smiled and ran his thumb along my lower lip. “Max, how far do you really want to go?”
I blushed again. “All . . . all the way.”
“Like Mommy and me 'all the way'?”
I nodded my head.
He stared at me intently before looking around. “Let's try something out,” he said. He leaned forward while putting his hand on the back of my head and pulling me toward him. He kissed me, and as soon as I felt his tongue I opened my mouth. I copied his movements with my tongue.
When he broke the kiss, I was rubbing my hard-on through my shorts.
“Pull down your shorts. Show me your butt.”
I undid my shorts and shoved them and my briefs down before moving onto my side so he could see my rear.
I melted as I felt his fingers rubbing my butt cheeks. I moaned when his hand moved into my crack, and soon I felt a finger entering me.
“Oh, Daddy!”
He fingered my hole briefly. “Fuck, another car,” he said and pulled it out. I quickly slid my shorts back up. We pulled out of the park and drove for a while in silence.
“Tell you what, Max. Tonight we can spend the night in the treehouse as its breaking-in. You'll go up first. When I join you, if I find you naked, I'll know for sure you want to go all the way.”
“I'll be naked!”
“Just make sure you really want this, bud. I don't want to get started and have you change your mind.”
“Deal!” I practically shouted. He tousled my hair.

After dinner, he helped me get stuff up into the treehouse. When it was close to bedtime, I said goodnight to my mom and quickly went outside. As soon as I was inside, I practically ripped off my clothes. It was fun sitting there naked while I waited for Dad.
It took longer than I had expected, and I was starting to get worried he wasn't coming. Finally, I heard the sliding glass door open. I looked out the window and saw it was definitely Dad. He was wearing only lounge pants.
As he began climbing up, I lay down on my open sleeping bag. I wanted him to see me right away. As soon as his head popped up through the entry, he saw me and smiled. “I was hoping you hadn't changed your mind.”
He sat down while he took off his shoes, and I watched him as he slid off his lounge pants. He took a bottle out of a pocket and placed it next to the sleeping bag. He crawled over to me, and we began tongue kissing. 
As we kissed, my hand sought out his hard dick. I began stroking him.
“You want that big cock pretty badly, huh?”
“Yes, Daddy!”
“I sure hope you can handle it. May hurt at first.”
“I can take it!” I just hoped it didn't want to make me scream.
He picked up the bottle and squirted some stuff onto his dick. “Rub that up and down for me.”
I did as he said while he turned on some music.
Once it was playing and he adjusted the volume, he had me move onto my side. I was breathing hard already. I felt him sliding into my crack, and I pushed my butt toward him.
He chuckled. “Eager to get it in there!” I felt it push against my hole, and he entered me. 
I pulled the pillow up so it covered my face because I was so happy this was happening. He slowly pushed into me. The stinging began. I decided to make this go quicker and started to move backward. I took a couple of deep breaths when the burning began and continued pushing my butt onto his stiff dick.
“Fuck, Max! I want to be all the way inside you so bad.”
“Do it, Daddy!” I hissed.
He guided me onto my stomach. I loved feeling him on top of me. “This is gonna hurt, Max.”
“I don't care! I can take it.” I buried my face in the pillow again.
He made a few back-and-forth passes before plunging it in the rest of the way. I was glad I had a mouhtful of pillow! White light flashed before my eyes, and I had to remind myself to breathe.
I guess I was wrong he was all the way in because a couple of breaths later, I could feel more of him sliding into me, and I could feel his body pressed against mine.
“You doing OK?” Dad asked as his chest rested against my sweaty back.
I nodded my head.
“You're doing such a great job, Max.”
He was supporting some of his weight on his hands, and I could feel him moving his hips side to side a bit. Soon I could feel his dick moving again. He was pulling it back a bit slowly before returning it. This motion seemed to help my hole relax. After a bit, I was able to release my bite on the pillow.
“How does that cock feel?” he asked.
“It still hurts a little, but it also feels really good.”
“Your mom had a hard time taking my dick for the first time, too. You'll get used to it.”
He started moving it more now.
“So . . . are we going to do this more?” I asked.
He kissed my cheek. “Oh, buddy, I plan on having you suck my dick and me fucking you often.”
We tongue kissed.
“You want that, too, don't you, bud?”
He started moving his dick back more. He was still moving it forward slowly after each of these moves, and it was making it hard for me to think. “Gawd, yes, Daddy!”
His hot body felt good being against mine as he gently slid his meat back and forth in my hole. “I can't believe how good you feel, and how well you're taking my big cock.”
As he continued humping my butt, the stinging calmed down. Mostly. After a bit, he guided me onto my knees. My chest was still on my sleeping bag. He took hold of my hips as he began moving a bit faster. I was feeling things I had never imagined, and I wanted to moan loudly, but I knew I couldn't do that in case Mom heard. So I bit into my pillow.
A few moments later I heard him say “I love watching your ass swallow my dick. You're such a good boy.”
“I want to make you happy, Daddy.”
“Oh, Max. I'm the happiest and luckiest dad alive!” he said as he began moving a bit faster and harder. “You're so tight I'm not going to last long, buddy!” I felt him plunging his dick into me harder, and I had to take a mouthful of pillow again.
He kissed me hungrily as I felt him moving his meat fast and steadily in my aching hole. Soon he wrapped his arms around my chest, and I could hear our bodies slapping together. It didn't take long before he was lying against me still while I could feel his dick pumping inside me. 
We kissed more gently as he caught his breath. When he rolled off me, I cuddled up against him. He guided my head up so we could tongue kiss some more. “I love you so fucking much, Max!”
“I love you, too, Daddy!”
We lay snuggled together for a bit. The only noise I could hear was his breathing and his heartbeat as my head was on his chest. His fingertips moved up and down my arm that was lying across his chest.
Soon I felt movement so I moved. He had a wet wipe and was cleaning his semi-swollen dick and his big balls. When he was done, he kissed me again but harder. “Why don't you use that sweet mouth of yours to get me hard again.”
I smiled and moved down his body so I could suck on his sac and his rod. As I began working on his dick, I felt him readjusting my body, and soon I felt his mouth on mine! His hands massaged my butt cheeks as we worked each other's meat.
Once he was good and hard again, he guided me so that I was straddling him. “This time you're going to sit down on it and ride it like a cowboy.” He gripped the base of his dick as I tried to get into the right position. It took a few tries before I felt the mushroom-shaped tip enter me.
“Yeah, Max. Sit down on that cock!”
I bit my lower lip as I felt his thickness enter me. His hands massaged my upper thighs as I continued moving downward on his rod.
As I took more of him into me, his hands moved up and down my bare body.
“I want you so bad, baby!” he said softly, and I forced myself down more. That time it hurt more so I stayed in place with my eyes closed as I tried to push aside the pain.
Once I began moving again, he said “Yes! Take that fat cock, boy!”
Soon he was moving his hips, and I kept lowering myself as fast as I possibly could. He was rubbing both of my nipples. After a bit I felt him sliding his feet so that his knees were bent. He started thrusting upward more.
“Your ass is such perfection!”
I took a few deep breaths and just forced myself all the way down. Even though my eyes were closed, I could see bright light. I leaned backward a bit so my back could rest against his legs. I focused on my breathing as I adjusted to the feeling of his thick meat filling my insides.
Once I had adjusted I started moving myself up and down since I figured that's what he meant when he kept telling me to ride him. During part of this time, he pulled me down to him so we could kiss.
When he finally came, I was exhausted. It seemed like I fell asleep as soon as I lied down. In the morning I was awakened by him sucking on my nipples. His lips moved down my body until he had my dick in his mouth. “I'm gonna need more of that ass before we go down for breakfast,” he said after getting me nice and hard, and I felt him lifting my legs up.
It was nice being able to see him while he was on top of me, and because of the sunlight I could see the look of lust and pleasure on his face. This treehouse was definitely a new beginning, and I was loving it.
