Then I thought that having a couple of brats with me would add to my cover of being a kid going to play on the beach.I gathered my things together and...started to put them in a big bag then changed my mind and just put the smaller items in a small bag. I wanted the towel and bucket and spade to be visible.I was just locking up when the kids appeared with a bag. I was pleased to see that the girls still only had her bikini bottoms on.“Are you going like that?” The girl (Kate) asked.“Yes; why?” I. Rich took more lube and dabbed it on Nat's ass and then his and it was clear he wanted to be first. Not knowing what to really do I got the head close to his hole and slid in slowly. First the head, then half way I stopped before easing back and forth all the while Nat had her face in a pillow and fingering her pussy in front of me and using an anal plug herself. I pulled out and moved to Nat slowly entering her. She was also tight and I stopped half way not wanting to hurt her either. A. On but nothing that day i guess everyone checked out on time but as i was making my way down i remember awhile back we were talking about some of are fantasy that would not come true and one of her's was to be fucked by a stranger cause we were together she said it would not come true so i thought to myself that this the prefect time for her to have it come true in my head i thought it'll be fun for me to sneak up from behind and just fuck her i had i smile on my face as i turn into the rooms. I would talk to him after he’s changed. I waited a few extra minutes after I was done changing then headed out. Nearly everyone was out of the changeroom but I assumed he would take his time. I came around the corner and he was sitting by his locker on his phone. “Umm, your Black right?” I blurted out. He didn't look up right away. He kept on typing, sending a text or something. After about 5 seconds he looked up. “Yea, fuck do you want?” he finally responded.“Umm, I think you met my sister.
