It all started one evening, I was in the shower and had forgotten to lock the door. I hear banging on the door and my sister came in. She’s wear...ng a dress. I think, “Holy shit, she’s out of his mind, this is crazy!”I gasped and told her to get out. I guess I said the wrong thing. I didn’t want her to feel dirty or uncomfortable. I didn’t even know what she was feeling. My sister glanced down at my dick. I watched the reflection in the window. She made a sad. Prissy then mounted Tuck again, this time squatting above his torso and slowly sliding down onto him taking his erect prick into her sloshy wet pussy.Prissy began to ride him sliding back and forth. She screamed, “I’m going to ride you like a race horse!”Tuck could not believe his eyes. It usually took much cajoling to get her to fuck him cowgirl style and now she was doing it without his asking and with overwhelming enthusiasm. For a few minutes Tuck thought Prissy might break the springs in. ‘Ohh, um, yes Tony. I’m just out from the shower.’ ‘Okay then. When you wasn’t in the kitchen, I thought, I better check up on you.’ ‘Thanks Tony, but I just overslept,’ Carmen replied, ‘I’ll be out in a minute or two.’ ‘All right. Maybe I should go check on Ryan. I didn’t see him either.’ I quickly bent down and whispered into Carmen’s ear, ‘Say, you heard me leaving for a run.’ ‘I….I think he went for a run,’ Carmen stammered. As the words left her lips I flexed my still hard cock inside of. Yavara was breathing laboriously, her lids fluttering, a vein in her forehead revealing itself and pulsing with her temple. Prestira yawned. A vessel burst in Yavara’s eye, and Prestira collapsed on the floor. I gawked disbelievingly as Yavara let out a whoop, and leapt to her feet. Prestira rose slowly to her knees, her hands dangling from her arms as though she was a dog. Yavara strutted over to her new pet and stroked her hair, and Prestira reciprocated with panting canine affection. .
