When I was 5 I used to let my older first cousin, a girl of 9, watch me when I peed outside at our farm She liked watching me make marks in the ground as I squirted around. Twenty five years later, when we were both single and at a family reunion I hosted she was the last person to leave. She helped me clean up the dishes. Afterward we sat on the couch, then we kissed, then she asked me if I remembered showing her my penis when I peed. We slipped into the bedroom and fucked all night.

Here's a little story that I've only told a couple times in my life. You know it's true because there's basically no climax. It's almost boring, actually.

I live in Japan. A couple years ago, I lived on the 2nd floor of an apartment building that had a house right behind it. A family lived there, and from the 2nd floor hallway of my building, you could see through the house's glass back-door into their living room.

To make a long story short, I happened to look in one day to see the roughly six year old girl that lived their making out with one of her older siblings. I think the older one was also a girl. And that's it. They did it for a couple minutes, then the little one ran off while the older one slept on the couch.

It was hard for me to believe. I once visited my cousins in Florida, and while playing with the youngest one, we did the touch-foreheads-together-and-make-funny-faces game. My much older cousin later said that when she saw us doing that, she thought we were kissing at first. Here in Japan, I asked myself if I could be confused like she was. It's definitely possible. However, it really looked like they were making out.

I never saw anything else like that happen again at their house. I moved away a few months later.

I fucked my 1st cousin's wife at a wedding in early August, didn't pull out of her and I just found out she's pregnant (5 months later).
Heather was already a bit tipsy when she got to the wedding reception. My cousin was arguing with her that she needed to "chill out," but she wasn't having it. I always thought Heather was a pretty girl, only 23 years old (I'm in my mid 40s), and she was always showing off her cleavage. Heather is slightly chubby, nice and thick and has some massive tits to be proud of and I always wondered what they looked like and how they felt. Well I got to find out.
During the reception, she kept stepping outside to have a cigarette, avoiding her husband since they were arguing. I haven't had a cigarette in years, but followed her outside and asked to bum one off her. It was a primal urge, just to get a nice glance at her sexy tits and have some conversation too.
"Sure, you need a light too?" She asked, looking right into my eyes. I glanced down at her beautiful tits.
"Yeah," I told her, and she lit my cigarette, and as she did she pressed her massive tits into the side of my body.
She giggled, "sorry, I'm a bit tipsy. I didn't mean to offend you by pushing my tits into you."
I blushed, "Oh not a problem at all!" I said laughing.
"Oh really?" she pushed them into me again, this time a bit harder. My cock was twitching, ready to spring into action.
“It’s like I’m in heat,” she whispered drunkenly.
"Yeah, really Heather, I'd never deny you pushing your tits on me!" I laughed.
She grabbed my hand, threw her cigarette down and said, "come with me."
I followed her, looking around to see if anyone else was watching us sneak off. Luckily no one else was outside with us, and it was nice and dark out.
She found her minivan in the parking lot and opened the door, and when she climbed into the back seats, she slid her panties off, revealing a pretty nice trimmed bush.
"I don't know if..."
"Shut the fuck up and get in here," she told me. Heather was drunk, and my morals were out the window.
I did, she pushed me down on the seat, unbuttoned my pants and pulled my hard cock out and started to suck on it. She went all the way down to my balls, making slurping and sucking noises. I could smell her perfume, and alcohol she consumed combined with cigarettes.
I reached under her dress and pulled out one of her massive tits, she had lovely nipples and large pink areolas. I saw her lifting her dress and start fingering her pussy as she sucked on my cock. I pinched one of her nipples softly as she moaned.
She pulled up for air, "damn this is a big dick, I miss big dick."
"It's not that big it's only 6 or 7 inches," I tried to tell her as she got on top of me and shoved my dick inside of her.
She started bucking and I pulled at the top of her dress and pulled her breasts completely out. I put them in my mouth, trying to pay attention to each one - I thought ironically, "this is the way I want to die, big ass titties in my face," as she kept bucking on my cock.
She twitched a little and told me she was coming, and moaned. She kissed my lips, and then started moving up and down on the shaft of my dick with her wet hot cunt.
"Your turn," she said, biting her lip.
And I did cum, I came a lot. I felt her moving faster and faster as her beautiful tits bounced in my face and I grabbed her ass and kissed her lips as my cum shot deep inside her. After I was done nutting in her, she got off, and pulled her panties up, straightened out her dress and hair.
"Oh, that was so fucking hot," she said taking a deep breath, "phew!"
Reality was setting in for me; I just fucked my cousin's wife.
"Um, this never happened ok? Shit."
"Oh don't worry silly, no one will ever know. Get back to the wedding, I'll be inside in a bit."
I put my cock away, zipped up my pants and got out of her van. That was the last time I actually saw her, as we really never get together for family get-togethers.
Now my family isn’t that close, and I really don’t talk to my cousins that much at all so it’s only rare occasions we get together.
The other day my mother called me with the news, "Oh, Uncle Bobby called, your cousin's wife Heather, she's pregnant! We just found out. She's due in May!"
I did some quick math. May is 9 months away from August. I’m 90% sure I bred my cousin’s wife.
If given the chance, I'd definitely fuck her again. My cousin is a lucky guy. Kinda wish I could see her big milkers filling up with milk.

I kissed my gf's much younger cousin and I feel guilty about it. I'm just hitting 30 and her cousin is 19. I've known her forever and we're close. She's always told me she loves my hugs which I blew off for years because she was literally underage and a kid. But the other day she asked for a big hug and when giving it to her I instinctively kissed her neck. It was an accident, I wasn't thinking. But she squeezed me tighter, let off a bit of a sigh, pulled my head back then full on started french kissing with me.

It was hot, my hands went down her back just above her ass, I was getting turned on, then it stopped. The whole thing was over in seconds and then she said 'that was hot. And then -- nothing. She acted like it never happened.

I have no idea what to do. Honestly, I never really thought of her that way until then, even though her body type is pretty much what I look at on motherless to stroke to. I've never fantasized about her - she was like a sister to me. Now, it's all I think about.
