They heard the shower running, then CC called the girls. After 10 minutes, CC called Alton. He walked in to see CC on her knees ass up. Her jet black ...exy night gown covering her. He looked at the girls with wicked smiles on their faces until they lifted her gown baring her ass. Between her pink cheeks he saw her brightly red ass hole lips. It seemed to be 6 inches long much larger than normal. He stripped and eased behind her, CC said “Cock and balls, Dear! I want it all. The girls helped me”.. She sucked all the blood and rolled over me to come up. It was her turn to bite me. My sister started kissing me all over my face, my neck and went to my chest now. She bit me there several times while I dug my nails in her back!Then my sister removed her t-shirt and I started pressing her boobs. My sister wasn’t wearing a bra at night. I sat up and started to suck her melons and bite her nipples. They were all erect. Nothing is better than a sight of erected nipples on huge boobs! My sister. “Off, Buddy. This thing is mine.”“Yeah? Finder’s keepers, Heather, right?”I heard her laugh as she let go of my knee and grabbed on to the tube and tried to lever herself on board. Instead the tube flipped over and as I fell into the water I grabbed Heather and hung on. In our tangle my nose ended up almost in her armpit, which sounds gross even if it wasn’t. She smelled of chlorine and of something else I couldn’t identify. When I think back on it now mostly I remember being confused.Heather. I could hardly sit still on the chair as she slowly took off the thong and came closer. She spread her legs and showed a trimmed bush with black hair. My eyes nearly stood out of my head as she took her hand down to her pussy and put one finger into it. When she took it out again she put it in her mouth and licked it. Then she took my hand and took it to her pussy and said Put your finger in and feel how wet I am. I slowly introduced my finger in her pussy and felt the softness of her pussylips.
