Now all those beers were really taking effect on both of us, and we were becoming less and less inhibited."You said you were going to teach me about d...cks, so teach me," she said boldly, not hiding the fact that she was checking out my penis. I was almost afraid to touch it, but I had calmed down a little over the last minute after her pussy had disappeared from view, so I gently grasped my cock with my right hand."This is the shaft," I said, sliding my hand up and down my throbbing, veiny, red. " I was starting to answer her as his cock slipped out of my mouth. He started cumming and squirted all over my face and chest. She was fingering my asshole while I sat there covered in cum and said, "How does that feel?" as her cum coated fingers slipped inside me. I moaned. She said, "Imagine how good a cock would feel" and I said just went along with her and moaned. Just then, the door opened and Shelly was standing there again holding her camera. I got dressed and followed Denise and Shelly. “Oh hell Pattycake, I’m sorry. I shouldn’t be talking like that around you.” She stared at her father’s slumped shoulders and decided to take the risk. Patty slid her hands under her father’s shirt and continued down his back. “It’s okay. I already knew.” “What? How?” “Can’t help but to hear mom fucking herself with her vibrator every other day.” Patty’s hands moved onto his lower back. Her touch mellowed to. She winced at the entry of Betsy's finger up her own fist-raw pussy, but she took it like a trooper, then pulled the finger out and steered it to her own tingling asshole.The slim finger ventured inside, screwing and reaming with a passion and fury that echoed the hard thrusts of Bob's cock up Betsy's shitter."Oh, Daddy, Daddy, Daddy!" Betsy cried. Becky punctuated the cries by thrusting her fingers deep into her twin's cunt, rubbing harder at the girl's totally aroused clit while she fingered.
