As she was walking away, the cockiness came out of me and I said, “that ass is mine tonight”, she looked back, with this come and get it smirk on ...her face.About twenty minutes passed and both of Mike's friends left with the women they came to the party with, both of Mike friends were also idiots that’s probably why they were all friends. This is normally when Mike leaves the party and goes to bed, at least that seems to be his pattern from the last two parties I attended. It seemed like most. Piper went to her back, I pushed up her shirt and bra to bare her tits. I licked and tickled her nipples while she jostled around then pulled me into place between her thighs. Again, we didn’t need a lot of foreplay, we were brother and sister, not lovers, so there was no reason for a lot of warmup or anything. I plunged, she gasped and grabbed my back so hard she scratched me. Piper pulled me flat on her, wrapped her arms around my shoulders, her legs encircled my thighs and I put my hands. As I started to take off my spandex, Anna stopped me.“No, no my dear let me do that for you,” she said in her sultry voice.Anna peeled off my top and sport bra and complemented me on my breasts again. “They are so lovely and just the right size. I love you hard little nubs,” she said as she kissed, sucked, fondled my tits and tweaked my nipples.She was so gentle for such a physical woman. She worked her way down my body to my abdomen and kissed me along the waistline. She pulled my shorts down. I’m hungry. We are not going to go home, take showers and get dressed and go out again in three hours.”Lizzie protested as well, then the two began digging through their bags for hairbrushes. “We don’t have any makeup!” Lizzie complained.“You two are only fourteen and you don’t need any makeup.” he replied disapprovingly.The girls protested at that, though their aunt smiled to herself. She would need to work on her brother this week. She had noticed both girls weren’t wearing their bikinis.
