My sister's boyfriend Donovan has interested me ever since they started
dating. He has blonde hair and bright blue eyes. He's a swimmer, so I've
had a chance to see his body, and it definitely has my interest. I've also
not been able to help but notice the big bulge in his Speedos. At first I
thought my curiosity was just because we have no other men in the house.
It's just my mom and my sister and me. But whenever I look at him, I'm
always very curious about what he has in his pants. Especially since I've
overhead him and Jean talking, and I know they aren't having sex. He's
always nice to me. I just couldn't resist anymore.

He was downstairs hanging with me while my sister got ready for their
date. We both knew that would be a long affair.  We were sitting together
on the couch. I couldn't think of any other way to say it, and so I just
blurted it out: "Don, would you let me see your penis?"

He had been taking a drink and almost spit it out. "What?"

"I'm just curious what another guy's looks like."

"You'll have health class soon. Maybe then. Or try the Internet!"

"But, those aren't real. I want to see one up close. Please?" He looked
like he was considering it, so I added, "I'll make it worth your while."

He chuckled. "And how would you do that?"

"I'll give you a blowjob."

His mouth fell open, and I saw his cheeks turn a bit red. "Dude, how do you
even know that word? You're like 11."

"I looked stuff up on the Internet. I'm curious. Please?"

"What about Jean?"

I rolled my eyes. "We both know she won't be down here any time soon." As
he was thinking about it, I began undoing his zipper.

He looked at the stairs but didn't move to stop me. "Okay, you can look,
but don't tell a soul!"

"I won't!" I said cheerily. He undid his belt and pants, and slid them down
before shoving his boxer briefs down as well. I turned on the light next to
him so I could see better. He had big balls and a thick dick. There was a
bush of light-colored hair around his cock. It was similar to his other
hair, but a bit darker.

He turned down the TV so he could hear better while I continued examining
him. I touched the wiry hairs before running my finger along his penis and
balls. "I didn't say anything about touching little man."

"If I suck on it, won't I be touching it?"

He looked at me surprised again. "You were serious about that?"

"Fair's fair," I said. To prove my point, I leaned down and put his dick
inside my mouth. As I sucked on it, his dick began swelling rapidly. I
could smell the scent of chlorine on his skin. I ran my tongue up and down
the shaft feeling the veins and the skin.

When I went down on him again, I looked up and saw him looking at me
intently. His blue eyes seemed to burn as he watched me suck on his tool. I
got on my knees so I could be right over his lap, and I started pushing
more of his dick into my mouth. "You liking that?" he asked. I nodded and
went down on him more. I think they call it deep throating. But it made me
gag, so I couldn't go as far as I wanted.

Soon his hand was on my head pushing it down while his hips started
pumping. It made me feel amazing to have his dick in my mouth and to feel
his excitement. He pushed his clothes down more and spread his legs wider
before telling me to suck on his balls. They had a lighter coating of that
same fur on them, and I loved how they felt in my mouth.

At one point, I started going really fast, but he told me to slow
down. "There's no reason to rush this," he said. He let me go to town on
his dick, and I adored every second of it. Especially when he would put his
hand on my head or neck and push me down. It excited me.  After going for a
while, he finally told me I could speed up again. I heard him softly
moaning, and I could feel his leg muscles shaking. His dick seemed to swell
inside my mouth, and a few moments later I was coughing as salty stuff
sprayed inside my mouth. I had read guys want you to swallow when this
happens, so I just kept going which prompted him to say "Fuck!"

"Am I doing it wrong?" I asked, worried.

He shoved my face back down, and I returned his cock into my
mouth. "No. Not a damn thing wrong."

I continued sucking him until his dick stopped twitching as much. He had me
suck on his balls again before giving his dick another cleaning before he
had to pull up his clothes. I managed to talk him into leaving them down
until we heard my sister so I could check them out more. He even let me
push up his shirt and feel his muscles. I got to suck on his nipples, too!

Jean was done, so we had to end our little play. "I hope you'll let me do
that again, Don," I said as he stood up to get his pants back on.

"You had fun with that, huh?" I nodded my head. He looked at me seriously
for a couple of seconds before tousling my hair and saying, "Well, that
might be able to be arranged." Just then my dumb sister called for him, so
he said goodbye and headed upstairs.

Two days later I was at home after school and heard a knock on the door. I
opened it to find Don standing there. I greeted him and stepped aside so he
could come in. "Jean's at work," I said as he took his shoes off per Mom's
policy.

"I know. I came to see you."

"You did? Cool! Want to play some video games?"

"Maybe later, bro. Actually, I was hoping for another blow, Brady."

YES! I was so excited! "Sure! But this time can you be naked?"

"You're a bit of a little freak, you know that?" he asked.

"I'm not sure what that is, but will you?"

He looked at his watch. "What time does your mom come home?"

"She's working a double, so she won't be home until after I'm in bed."

He rubbed his hard-on through his jeans. "Tell you what. I'll get naked if
you agree to give me another blowjob if I want it."

"Any time you want!"

"I mean today."

"That's fine with me!"

"Cool. Let's do this in your room."

I walked hurriedly to my room. He shut and locked the door. I sat down on
my bed and watched eagerly as he stripped out of his shirt. He smiled at me
and came over to my bed. "You want to feel?" he asked playfully. I stood up
and ran my hands over his chest and abs. "You like that?" I nodded. "You
know, not even your sister has seen me naked."

"Yay! I'm first!"

He laughed at that and started to unbuckle his belt but stopped. "Actually,
why don't you take my clothes off me. That will be hot."

I smiled and began undoing his belt. He rubbed my head gently as I next
undid his jeans. I slowly unzipped them getting excited about the tent I
could see in them. I lowered his pants and began to grab his
underwear. "Just a second," he said. "Take the pants and socks off first,
then the underwear."

I did as he said, and when I returned for his briefs, he guided me. "You
want to make this fun for the guy. Tempt him. Get him so excited he can't
stand it anymore." He took my hand and slowly ran it over the outline of
his cock in his boxer briefs. Then he had me wrap my lips around the
outline and move up and down the shaft. "Now slide your fingers inside the
fly and stroke my dick. You want me to feel like you treasure my cock."

"I do!" I said, doing as he instructed. This was so much fun! As I slowly
felt his hardness, I also put the head of his dick in my mouth through his
briefs. He had me tease the head with my lips.

"There you go! Now slowly lower my underwear. Let your fingers run along my
skin. The more contact you make, the hotter it is. When you go slow, it
also increases the anticipation, and guys like to feel like you're serving
them." I looked up at him as I did this, and he said "Yes! Hot, dude!"

When I stood back up, I was going to put his dick in my mouth, but he
stopped me. "This ain't a rush job. You wanted to see my naked body, now
you need to worship it. Lick my muscles. Make my cock ache for your mouth."

I did my best to do what he wanted. Around his belly I noticed a thin trail
of hair leading to the blonde bush above his dick. I teased the hairs with
my teeth as I worked my way down. I ran my tongue from the base of the
shaft slowly to the head while he said "Fuck! What do you think of my
body?"

"I love it! You're like. . . a god!"

"Nice touch. Now take your clothes off." He wanted me naked, too! That was
even cooler. He watched as I stripped out of my clothes. He had me show him
my hard pecker. "I knew you'd be excited. How bad do you want my cock,
Brady?"

"Bad!"

"How bad?"

"I. . . I'll do anything!"

He sat me down on the bed, and he gently slapped me in the face with his
hard dick a couple of times. "Now make it happy, little man."

I opened my mouth, took him into it, and began slowly sucking him. When he
pulled his dick up so that it was against his belly, I sucked on his
balls. "You're gonna make a damn good cocksucker."

After a while of moving back and forth on his thick shaft, he got on my
bed. He stretched out, sitting against my headboard with his legs wide
open. I moved between his legs and continued where I had left off. I looked
at him and his amazing body as I blew him. Soon his hand was on my head
again, pushing it down at a faster pace. I reached under him and took hold
of his butt as he began pumping his dick into my mouth. Tears streamed down
my cheeks as he kept making me gag with his big dick, but I never stopped.

Soon he slowed down, and I wiped my face and sucked on his balls to give my
throat a break. "Damn, I'd love a photo of you sucking my cock," he said.

"You can take one."

"Better not have evidence." I continued sucking him slowly until he asked,
"Okay if we get a little rough?" I nodded with his dick in my mouth.

He smiled and moved off the bed. He grabbed me by the legs and pulled my
body down the mattress some. He had me flip onto my back. He straddled me,
and I watched as he lowered his body toward mine. I opened my mouth and
took his dick into it. He began slowly moving up and down, but soon he was
pushing his cock down my throat even harder. I grabbed onto his waist as he
filled my throat and kept it in that position for a bit before pulling it
back.  Every so often he would do rapid thrusts into my throat making me
gag, although I did notice that as we started to get a rhythm going it was
getting easier to take more of his thick meat.

After a while of this, he was back in his former position. "Suck on my big
toe," he said.

"That's gross!"

"You said you'd do anything for my cock."

"Eww. Not that. That's nasty."

"Okay," he said, and started to get up.

"No, no, no! Okay, I'll do it."

He took hold of my chin. "If you want to keep sucking on this fantastic
dick, you have to do what I say when I say it, even if you don't like it."
I nodded. When he let go of me, I went down to his feet and started sucking
on his toe. It actually wasn't that gross. When I looked up at him, he was
slowly stroking his cock. "Now get back on the bed between my legs with
your butt facing me."

I did that and went back to sucking on his toes and licking his feet, after
he told me to do that, too. As I did this, I felt his hands rubbing my
legs. His fingers slowly ran up the inside of my legs. I shivered as his
finger grew closer and closer to my balls. He lightly rubbed my sac and
gently stroked my dick as I treated his toe like his dick. Then his hands
cupped my butt and slowly rubbed my cheeks. "Okay, back to my cock," he
said finally.

I turned around and went back to sucking him. We changed positions a few
times, and he alternated between fast and slow throughout until at last I
was drinking his salty liquid. When I was finished milking his dick, he let
me cuddle naked with him. I ran my hand up and down his shaved legs and
torso, and I also loved playing with his pubic hairs.

We took our clothes downstairs so we could play video games while naked but
could get dressed in a rush if needed. When it was getting close to the
time my sister was getting off work, we got dressed, and he left. Later
that night I was online, and he popped in. We did a video chat, and he
showed me his hard cock and told me he was thinking of me.

He came the next two days for blowjobs. After we had finished the last one,
he joined us for dinner. While eating, Mom mentioned she needed Jean to
watch me Friday night. She had an away cheerleading competition.

"I can stay with Brady," Donovan chimed in.

"You sure?" Mom asked.

"Yeah, he's a good kid. I'm sure he'll mind, won't you?" I nodded my head
vigorously. "There you go."

"It would be overnight, Donovan."

"No worries. We'll have plenty to keep us busy."

"If you're sure," Mom said.

"Absolutely positive."

It was settled! I almost jumped for joy.

He had to skip the next day, so I was extra excited by the time Friday
rolled around. Mom was already at work, and Jean was on the bus, so I was
home alone for a bit. As soon as I got home, I stripped out of my
clothes. My little dick was hard almost the whole time until I heard the
knock at the door. I stood behind the door and opened it. He entered and
peeked around the door. "Well, someone is a bit eager to begin."

"Yes, I am!"

I followed him to Mom's room, and he set his stuff down. "You ready for
lots of cock?"

"Always!"

"And you'll do anything I say?"

"Of course," I said bouncing on my mother's bed.

He gave me a beautiful smile. "Good. Now come over here and get started."

I sat on the bed in front of him and undid his jeans. I quickly pushed his
pants and boxers down so I could get his delicious dick into my mouth. As I
began blowing him, he peeled his shirt off. I loved looking at his body. He
stepped out of his clothes before taking hold of my head. I knew what he
was going to do so relaxed while he started pumping his cock into my mouth.

He made me choke a few times as he shoved his dick down my throat, but he
kept going. Several moments later he stopped and pulled out of my mouth. "I
want to try something new with you," he said, grabbing his bag.

"What is it?"  He pulled a plastic bottle out as he responded, "I'm going
to fuck you." I watched as he squirted stuff from the bottle onto his cock
and rubbed it up and down the shaft.

"What is that?"

"I'm going to put my dick inside you."

"Don't you do that when I suck on it?" I asked as he guided me onto my
tummy.

"This will be even better for me. I'll get to bury my whole cock in your
tight hole, and nothing feels better than that." He pulled me back so that
my hips rested at the edge of the mattress. My legs hung over the side as
he moved in behind me.

"How are you going to do that?"

I felt his dick sliding between my butt cheeks as he answered, "I'm going
to fuck you in the ass, the closest thing you got to a pussy."

I felt him enter me, and I didn't quite know what to do. This was really
weird. I knew about sucking dick, but I hadn't come across a guy putting
his boner up another guy's bum.  I started to breathe a little harder as
his meat pushed inside me and stretched my hole open wider.

"I'm not sure I like this, Don."

He pushed more of his hardness into my butt before saying, "You told me
you'd do whatever I said, remember? Now you like my cock, don't you?"

"Yes," I squeaked as he got more of it inside me.

"Good. Because I really like giving it to you. But if you want my dick,
you're going to have to let me fuck you sometimes, too. That's our
deal. You solid?"

I didn't like this new deal at all, but I also didn't want to stop getting
to suck and play with his cock. "Okay."

"Don't worry. I'll get that tight hole of yours stretched out a bit more,
and you won't mind being fucked." He began moving back and forth helping me
get used to his thick tool. "I knew you were going to be pretty tight, so I
jacked off before I came over so I could last longer."

He kept humping my butt as I tried to relax and breathe. It was kind of
hard, though, with his rod opening up like it was.

"Fuck this feels good! I bet your sister's pussy ain't even this tight."

I didn't want to imagine her pussy, so I didn't care. Besides it was taking
almost all my attention just to be able to keep my lungs inflating and
deflating. My butt stung as he kept pushing into it.

"You asking to see my dick was the best thing that ever happened to me," he
said just before he shoved more of his cock into my hole. He was moving a
little faster now, his fingers digging into my hips. "You doing okay,
Brady?"

"Yep," I said through grit teeth.

His hands slid up my back giving me chills. He gripped my shoulders almost
painfully, and I felt him shove the rest of his tool forward. I took a
mouthful of blanket as my hole ached bitterly. I could feel his hairs
against my butt. He was moving his cock back and forth in small movements,
occasionally doing a circular pattern. I kicked my legs a little bit, but
the pain started to die quickly.

"Once you get you used to it, you're going to love getting fucked," he
said.

I didn't believe a word of it, but I wasn't about to argue. He was moving
again. I could feel sweat forming on my back. He kissed me on the shoulder
before moving his lips to my neck. He moved his cock back and forth slowly
as he sucked on my neck. I found it even harder to breathe with him doing
that. I almost forgot about the thick meat in my butt.

Soon he was humping me harder. I grunted as his dick slid backward and
forward in my hole. "Goddamn!" he said, gripping my hips once again as he
sped up.

I started to feel pleasure from this. I had small fistfuls of blanket as he
moved faster. He smacked me hard on the butt which made me jump a bit. His
pace quickened for just a few more minutes before he yelled out "FUCK!" He
slammed his cock all the way inside, and I could feel it jerking in my butt
like when he was shooting that stuff into my mouth. He collapsed against my
back. I could feel his ragged breath on my damp skin.

"You know we're having sex all night, right?" he asked.

"I sure hope so!"

He kissed me on the cheek and said, "Best babysitting day EVER."
