I wanted to run to the bathroom to try and get his cum out of me, but I was frozen with fear and exhausted from the alcohol. It turns out I passed out...on the bed. When I awoke, another couple were going at it on the bed, mostly nude from what I could see in the low light. They noticed I was somewhat awake and asked if I was okay. I hummed a quiet ‘mhmm’ sound and they continued ravaging each other by the foot of the bed. I finally found the nerve to turn over a bit and see if the 28 year old. Faster, faster, faster, faster until she stops and starts again, this time grinding hard before bouncing again.Up and down. Hard and fast. Starting, stopping, and starting again. Both of us are moaning, groaning, and growling.Grabbing and holding her hips as she fucks me, deciding to join in, I thrust up and down a few times before rolling her on her back. With her legs wrapped around my body, her ankles digging into my ass, I plow into her. She screams for more, so I give her more. Hard, fast,. "Um... I don't have it on," I replied. "You don't? Where is it?" she asked, smirking again. "It's in the beach bag," I said, blushing and thinking about how scandalous they'd all think it was. "I'll get it!" said Leah, who took off for the kitchen and was back in a flash. I rummaged through the bag and found the bottoms, holding them up between my fingers. "That's not a bikini! That's tissue paper!" laughed Olga. "I'd buy that as lingerie!" said Denise. "You can see right through it,". About the time I was undressed and naked, Sharon suddenly walked in, asking what I was doing the next day. I did not have a chance to cover myself very quickly, and she sure got an eye full. “Oops sorry”, she gasped. She looked embarrassed, and quickly walked out. After changing, I went downstairs and in a few minutes Sharon came down, changed out of her bikini and into dry clothes, just ready for a shower. We said our goodbyes and Sharon gave me a pretty close hug as I left and I felt all.
