One of my favorites and most memorable was during a group skinny dip. This is back before FWB was a thing. This girl and I had been teasing each other mercilessly all night. As a group, we decided a swim was in order so the six of us shuck our clothes and hit the water. We’re now all hanging out in the water, up to our chins and it’s dark so not much to see. Four guys two girls. For the most part we’re all arms length apart and just making stupid jokes about fish nibbling, etc. So this girl, who has been driving me crazy all night, gets cute and slowly gets closer to scare me by grabbing my ass. It escalated into an all around water wrestle match between the two of with our friends rooting us on. I finally get her wrapped up and pulled up against me, my arms across her chest, her bare ass against me.... now recall we are all just friends and the most we’ve ever seen has been in bathing suits or maybe the locker room...needless to say...the playful wrestling moved to a bit of rubbing and touching...and, as a group, the other four decided they should leave us to sort the rest out. And we definitely did.
