Cousin Seduction on a Summer Birthday: A Forbidden and Erotic Family Secret

My cousin Jade and I have really close birthdays, hers is July 28th, and mine is the 27th, so we always just celebrate both on the same day. We were always pretty close, but not in a brother sister way. We almost never saw each other except for 2 or 3 days around our birthdays but we text a lot about everything.

When I was 12 I had my first kiss with her. It was an accident, I was laying on the couch and she tripped and fell straight on top of me, but we kept going for a few seconds because it was good. She winked at me when she got up and just kept walking, so maybe it really wasn’t an accident now was it…

Back when we were 14 we would experiment a bit… That year we were all stuck there for over a week because of a storm. There were only two extra bedrooms at my grandparents. My parents and Jade’s parents slept on the second floor with my brother (he has downs so yeah...), my grandparents on the first floor, and I always slept in the basement with my cousin. We were supposed to sleep on separate couches but after we kissed “by accident” we never did. We touched each other alot acting like it was an accident. Sometimes she swatted at a fly and her hand would just happen to fall onto my cock afterwards. I would stretch and my hand would fall over her breasts. They were small back then.

When we were 15 she wasn’t very attractive. I found myself not sleeping on the same couch as her that year, and it actually felt weird.

Now, I didn’t see her again until our 18th birthday, and damn how she had changed. Her hair used to only be shoulder length, but she had grown it out almost down to her cute ass. The freckles she once had were gone, and her piercing green eyes were gorgeous. Not to mention her breasts were the exact opposite of small now. I wasn’t bad looking then either. I had put on some muscle and such. My penis had grown a lot since I was 17. It was a little over 7 inches now and really thick.

At the time we were both virgins. Both our sets of parents and our grandparents had gone out for dinner and some stupid movie neither of us had any interest in. I had actually slept all day because the two of us were up until about 4 in the morning talking about all sorts of random things and “accidentally” touching each other. My grandparent’s house is actually relatively separated from the rest of the houses in town. They also have an 8 foot fence around the house because they have a pool, so there’s basically no way for anyone to see in. I woke up at around 6pm and walked out the back door, and found my cousin bouncing up and down on the trampoline in just her bikini. She was a little wet still from what I assumed was the pool. I sat down on the steps behind a bush just watching her. Her big breasts bounced up and down wonderfully, and when she stopped bouncing they continued to jiggle for just a couple seconds. She began walking toward the door and I hurried back inside and ran downstairs. She came down as well and I acted like I had just woken up. As I was about to get up she plopped herself down on top of me. My penis was getting a little hard and I could feel the lips of her pussy slightly threw her bikini bottom. Her boobs were right in my face and all I could do was stare at them…

At that moment the basement door opened. We both panicked and Jade practically flew to the other couch. As soon as I heard the loud thumping footsteps down the stairs I knew it was only my brother. He wanted goldfish and there was none left upstairs so I promptly got him a new bag of goldfish, pretzels, cheese-itz, and 6 pack of Gatorade just in case, and he went back to the top floor to watch his TV shows, overjoyed with all his favorite snacks. I took the opportunity to get up and get a shower. While I was standing there I got to fantasizing about Jade. What if we had sex? What if I saw her naked? What if we fucked all night long? I felt the sudden need to shave my penis and balls along with my face, so after I finished my face I went down low. One of the best feelings in the world is a fresh shave, and that goes for everywhere, not just the face. I stepped out of the shower, dried off, threw on a pair of shorts, and opened the bathroom door…

Sitting on the couch was Jade, still in her bikini, and her hand was down in her crotch. As soon as she saw me she pulled it away embarrassed. I really wanted to see what all of her looked like. I went and sat down on her couch with her, and just like old times her hand magically found my cock, and my hand founder her boobs. I looked into her eyes and before I even knew what was happening we were making out and groping each other. After a about a minute we came to a natural stop, and we just stared at each other. For a good 3 or 4 minutes we were just sitting there, looking each other up and down.

“You know how it’s illegal for someone who’s 18 to have sex with a minor?” She said softly.

“Yeahhh…?”

“Well you know I won’t be a minor anymore at 1:52am”

“That’s right isn’t it… well then…”

“I haven’t given you a birthday present yet…”

“Nope…” I knew what she wanted…

“Are you a virgin?”

“I might be.. are you?”

“Yeah”

“Well so am I”

“Do you watch porn?”

“Occasionally…”

“I bet you know how to fuck then don’t you,” she said slowly.

I knew what she wanted me to say… “I don’t know… why don’t we find out?”

“At 1:52am,” she said, and winked at me.

She got up and turned the lights down. Then she curled up and I let my body wrap around her. Soon we both fell asleep.

===================================================================================

“Hey Shawn… Shawn… Wake up Shawn…”

It was 1:51am. Jade was sitting on top of me smiling. We both turned to watch the clock. 10…9…8…7…6…5…4…3…2…1… 1:52am.

As soon as that second hand hit 12 she was all over me. I grabbed her ass as she ground it on my cock. She stripped my pants right off to reveal my big dick as I untied her top and bottom to reveal her beautiful body.

We rolled over and I kissed her from her neck down to her tits. I sucked on her nipples as she reached down and stroked my cock. Finally I continued down her body down to her sweet little shaved pussy. I ate her out just like I saw the pornstars do it as she moaned and writhed every which way. Then she pulled me back to her, reaching for my cock again. I still wasn’t completely hard yet.

“I’m so horny,” she whispered, “fuck me all night long Shawn.”

She got down on her knees and started sucking my thick cock. Her head bobbed up and down as I pushed her long hair back. I didn’t care about the blowjob I just wanted to fuck her.

Finally she lay on her back on the couch and I slapped her dripping wet pussy with my rock hard cock. I just wanted to shove it in there. But instead I slowly pushed the head of my penis in. I went deeper as slow as I could. Her eyes widened as the fattest part of my cock tore open her tight pussy. I couldn’t wait anymore and finally I slammed it the rest of the way in, balls deep, popping her cherry and all. She gasped loudly, trying not to scream, as I pulled out of her again. Then I went back in slowly and I could feel her pussy pulsing around me. As I fucked her slowly she shuttered a bit in an orgasm.

“Your cock… It’s so hard… Fuck me more…” She said.

I went faster and faster. I rammed my big cock in deep and back out of her as my balls slapped her ass. Her big tits jiggled as my pelvis smacked her over and over and she let out all kinds of moans and gasps of pleasure. I could feel her warm pussy clenching even tighter around me as I fucked her as hard as I could.

“I’m gonna cum soon,” I gasped. I was tired from fucking her so hard.

As I went to pull out of her she wrapped her legs around me, and my hot cum gushed out into her pussy as she shuddered again in another orgasm. She got out from under me and sucked away the sticky cum from all over my cock.

We kept fucking for hours as I came and she orgasmed over and over. She got on top and rode me when I was tired, and we switched again when she was tired. All the time her godly tits bouncing and jiggling mesmerized me. My cock had definitely permanently stretched out her tight little pussy that night.

When we woke up in the morning she was sitting on top of me. My cock was still in her and there was cum everywhere. She got on all fours and I fucked her doggy style one last time, and finally when I had to cum again I pulled out of her and she turned around. I let the cum fly out all over her big beautiful tits and we collapsed on each other utterly exhausted from sex.

We fucked again every night, every year after that. She told me later she had wanted this the moment she saw me again and had been on birth control. I have a girlfriend now and she learned about our little secret yesterday. She wants to come along next year and I’m really looking forward to that.
