Seeing her laying on the towel placed on the dark volcanic sand, wearing just a pair string tied bikini bottoms, the type that adjusted at the front a...nd back by pulling the material along the string to cover as much, or as little of her private parts as required, really turned him on.Sam would encourage her to reduce the size of the bikini so that only a two-inch strip covered her pussy and pubic mound. Sam, only 23 at the time, had to twist onto his front to hide his hard-on for anyone looking. Safely out of sight from the rest of the apartment, I quickly shed my bulky clothing and stuffed it into a corner.Underneath the top layer I was wearing an outfit that I'd picked up in a costume shop in New York. It was a Catholic school girl's uniform with a super-short pleated skirt, tight button-up shirt, and white knee socks. I'd put my hair into ponytails and finished it off with my black high-heeled mary janes. I checked my makeup in the mirror over the fireplace, making sure that it was. Almost failing to speak, she said, “Oh, my god; I didn’t know you were THIS big!” and, being a virgin I couldn’t really tell if I was a good size or not, but if she said it then I believed it. Amy then leaned back and began bouncing her pussy up and down on my cock, letting me see every inch of it go in and out of her juicy, wet lips. Just the sight of it alone almost made me orgasm, but I managed to contain myself. Not wanting to do all the work, Amy got off my cock and said, “Do me from. "Do you have a fitting room?" Sure, just through that curtain."Brenda gave me the panties and had me lead the way with her just behindme. She had me take off my shirt and try the blouse on first."The blouse really looks good on you." Brenda, do you mind if I do this alone!" Oh come on, in the apartment we've seen you in your underpants andyou've seen us in our bra and panties. So, what's the big deal? Now tryon the panties...you don't have to show me how the thong looks. Try onthe pale blue.
