I was glad to feel her riding me, to experience this amazing pleasure surging through me.“Oh, Daddy!” she whispered, being quiet while her throaty...moans burst from her lips.Her snatch massaged me. Teased me. It was the absolute best. I groaned and then thrust my hips upward. I bounced her on my cock. She gasped then clamped a hand over her mouth. She slammed back down my dick.I fucked upward into her again. And again.Delight shone in her blue eyes as I bounced her on my cock. Squeals of girlish. .reminding her that my girlfriend who liked to lay on her back as I jacked on my cock would finger her pussy. We watched each other come to orgasm. It would be helpful for this test you want to do if you would masturbate as well."sister Prudence, naked now and breathing heavily, lay back on the floor and said, "That was my intention Peter. Actually though, I don't think it is a betrayal of my vow when someone stimulates my vagina with a finger. Is that something you might want to do. Almosttearfully I went back to Kate's bedroom and took off her pretty yellowdress and then her pink bra and panty girdle and put them back in thehamper along with the panties I had used in the bra cups.When I returned to Ted's room he was still spreadeagled on the sofa. Helooked up at me and shook his head. "What can I say Greg. I'm going tomiss you."I said, "I'll miss you too Ted." What I didn't say was how much I wasalso going to miss the yellow dress.***A few days layer Ted and Kate were all. I spent alot of time at their house and I was close to my girlfriend's family. Her sister would regularly sit on my lap, lay across me on the couch, or just let me hold her in a non-sexual way. She acted all innocent like she was just treating me like a brother but I regularly got hard when she was touching me, especially when she was laying or sitting on my crouch. I would purposely push my hard cock against her just to make sure that she felt it and she occasionally grin like she liked it..
