I always liked to think it was all for me.And then she met my stepdad, which led to meeting my stepsister. She was every bit as attractive as my mom. ...She was a little chubby, and her tits were only 34 DD, but her ass was huge. It was hard not to notice it sticking out, especially wearing her yoga shorts.She had a boyfriend who was in his early twenties. Every night became torture. My room was perpendicular to hers and mom and dad's rooms. And when her boyfriend was over, it was like a cacophony. Alex and Ryan fucked and torture both of them the entire day. Amy and Trudy were having one of the best days of their life and all this was just a beginning. Both their holes were filled with either a dick or a dildo.That day, Amy was the slut who was getting tortured. Ryan had tied her to a cross bar in the dungeon, blindfolded and was whipping her body. Her mouth was stuffed with panties which were stuffed in Trudy’s pussy after Ryan and Alex had cum in her pussy. Those panties were soaked in. Deep down."No, I'm fine. Just something in my eye". I lied. She rang up the merchandise. The total. God. All my money, from my hands into Melanie's, for all intents and purposes. It felt so right. It felt so wrong. It felt so damn thrilling.The cashier eyed me a bit. She knew that they weren't my size. Melanie has nice size boobs, but I'm bigger, quite a bit. Melanie is also quite a bit taller than me. A bit different in the hips. The sales girl was a pro, she knew these had to be for someone. The triangular tops were each scalloped like a crescent moon to expose even more skin. And the bottoms were cut in a thong pattern that left her perky buttcheeks out in the open air.But even that yellow polka dot bikini couldn't draw my attention away from Amber. Like that one time by the pool at our Stanford apartment complex, my girlfriend had found a way to be supremely sexy without showing as much skin as the others. Her hot pink bikini with black trim actually covered the majority of her.
