Guys/ girls. share your most insane, wild, naughty, nasty, and fun sexual experience?

Hmm, heres one that was unexpected, happened a few day ago.

Me and my S/O were haning out at his house in one of the bedrooms. He was just sitting there watching TV when he turns to look at me, he had this weird, somewhat frightening look in his eyes, then suddenly he leaned forward and told me I was in trouble.

I got a bit upset and simply asked why and what I did wrong. He stood up and told me to get up, he yanked me, gently, but firm by my wrist and told me he was very angry with me. I just looked up at him, pouting, almost crying, and a little scared.

From there he pressed me up against the back wall with one hand over my wrists above my head and another around my neck.

From there he started biting a licking my neck, telling me I was a very bad girl =P

It kinda just got rougher and louder from there.

Once, we were staying staying over at my in-laws place one summer(wife's sister and her husband) I got up for a 2AM snack and I bumped into my wife's little sister, me in my boxers, and her white cotton panties and a thin tank top. We had been friends since we were kinds, so it was not that awkward. We both giggled a bit and sat down to eat. After a little small talk she burst out with, "So my sister told me you have a big dick..." I didn't know what to say, all I could get out was, "Really? She said that?" "Yeah. Do you think I could see it?" I thought to myself what the hell, "alright I guess" and I poked my flaccid penis through the hole in my boxers. "Wow" she was impressed, "how big does it get?" I looked at her and said, "well.." and I started to stroke myself. It was not long before I was fully erect, and I just kept going. We were both straddling the same kitchen bench seat so I had a very nice view of her moist white cameltoe which was now only about a foot away from my dick. I held out for a few more minutes before I shot my load right at her, getting most of it where I was aiming, the crotch of her panties. "Wow, that was hot!" she said "You know, I should probably go take care of this before anyone else sees" she said referring to the cum that she had started fingering as it soaked into her underwear. She said good night with a little smirk then gave me a little wave before she stuck her fingers in her mouth for a taste
