Had an older cousin who married at 25.  I was 16.  One of the bridesmaids took me into the parking lot of the country club and sucked my dick.  In SOMEBODY ELSE’S parked car!  Hot.

A step-cousin, or something like that. The first family gathering was in their home's vacant carriage house -- or rental unit in the rear.  That was the first of about twenty family gatherings over the next decade.  Got to the point where a week or two prior to the event whoever had better intel on where the extended family was gathering for the holiday, figured the best location for the dalliance. When I got invited to her wedding I sent her a good luck card with "I dare you," written inside.  

No, We didn't.

Mia Khalifa!!!  
I’ll drop my ALOT!!

My worthless stepson had a smoking hot gf.  She was 19 with a two year old.  Fortunately she was a crackhead.  We had several play for pay sessions on my wife's bed.  I don't regret a thing.  Fortunately my stepson ended up in prison.  His gf ended up as a hardcore street rat.  Unfortunately she left Orange County with her new daddy.  

...that when planning a friends and family destination birthday party for one of my toddler children, I chose the location partly because of its reputation as a sex tourism hot spot. No doubt the location was a major reason for the high turnout amongst my male friends. So while I was at the hotel dealing with caterers and clowns, they had themselves an orgy in a rented villa before eventually showing up at the party.

set meetings up with new friends and guests at the event to take place at a later time.  Usually a lunch or dinner meeting followed by BCD time.   I came of age in the late 70's and early 80's when pick-up bars were the most popular venues for hooking up for casual sex for both men AND women.  Its like riding a bicycle, once you learn the skills required, you never really forget how to meet someone socially and get them into bed fairly quickly.  

When I was in the military and single, I dated a woman who lived alone in an apartment way across town from the base where I was stationed, sometimes we'd only see each other in the weekends, which was when we screwed each other's brains out.

One of her sisters (who was married and had children) lived about half the distance between the apartment and my base. One weekend, my girlfriend and her sister were planning to attend their family reunion in another city, and would be driving there the next morning on a long road trip. Because they would be leaving early in the morning, my girlfriend would spend the night at her sister's house. There were a few other family members going along too, they also met at the sister's house and were spending the night, so the place was packed. I drove over to her sister's place to see her, she and I went out on a date and afterwards, I dropped her off late that night just as everyone else in the house was getting ready for bed. I went inside with her and chatted for a minute or two with sis and her husband and I met the other family members who were spending the night. They had to leave very early the next day, so one by one they said good night and soon it was just my girlfriend sitting there with me.

We talked in hushed whispers because there were people sleeping everywhere. In fact, the house was so crowded that she was relegated to a fold-out couch from the den that had been moved to an alcove by the hallway. She asked me to stay a few moments while she excused herself to change for bed and brush her teeth, and she joked that once she had done that, she wanted me to "tuck her in". She went into the half bathroom and closed the door.

I waited in the living room, the house was almost completely silent except for the symphony of faraway snoring from different directions. My girlfriend came out of the bathroom wearing a long flannel nightgown down past her knees, looking quite different in this household surroundings than these kitten I knew. She took my hand and led me to where she'd be sleeping. With a house jammed with family members, especially children of all ages, we had to be decent. At any minute, someone might get up to go to the bathroom or get something from the kitchen, and there we were right off the open hallway.

We sat down on her little bed and tried to keep it to a simple goodnight kiss and then I would leave, but the first thing I noticed when I hugged her was no bra strap when I touched her back. She whispered seductively in my ear that she had taken it off when she changed out of her clothes. We kissed, her breath the aroma of toothpaste and mouthwash, her soft lips teasing mine. Dirty pool, I was trying to be good. She playfully slipped her tongue into my mouth and I sucked on it, but she quickly withdrew it and broke off the kiss. Four hands were traveling everywhere over the clothing, but hard nipples and a hard dick aren't easily hidden by layers of material.
"I'd better go now, or we'll do something we're not supposed to do," I whispered to her.
"You're right, you're right," she answered. I wanted her and she wanted me, our normal weekend of raunchy sex was being interrupted by this family reunion, but we had to respect her sister's home.
"Ok, good night, Baby," I whispered, but then I cheated, I kissed her along her neck, not once, but a series of tiny wet kisses that tickled her. She moaned softly and hugged me tighter. "You'd better go," she said, even though her arms and body were saying something else.

I can't remember if she went for a handful of my dick first or if I went for a handful of her boob first. Verbally, we kept saying no, physically, we kept saying go. French-kissing each other all the way, we maneuvered to lift nightgown and lower pants, no condom, no lube, she straddled me and lowered herself, each of us had a hand on my dick guiding it in. We fucked slowly, silently and softly, she grinding downward, me thrusting upward. We couldn't afford the slightest noise or movement that would give us away, no squeaking furniture, no loud moaning, no thumping on the walls. We even had to control our breathing, accomplished by clamping our mouths together and not letting go.  

I was deep inside of her when I came. She kept riding me and milked my dick as I spewed again and again into her, the spooge oozing out and coating both our inner thighs and my balls. We held each other, still trying not to wake the house. Slowly, as I became softer and eventually receded from inside of her pussy, we unstuck ourselves from each other.

Unsure of how we hadn't been caught yet, I had to make my exit before that happened. We unceremoniously finished our goodnights and I let myself out. This was in the days long before cell phones, so we didn't have a chance to speak with each other until I called her from my barracks when she got back to her apartment a few days later. She told me that just like I had hobbled out of there that evening with my dick glued to the inside of my leg, instead of washing it off, she chose to spend the rest of the night with my sticky jizz between her thighs...
