First, our plan "A", we decided to build on the experience we had with Hannah and Clay when they lived with us. We encouraged Lindy to move in with us...as soon as they could. Once here in the house, Liz would start walking around in just her bra and panties to give Bill an eyeful. We also would leave our bedroom door open at night so they could see and hear us making love. Lindy said, She would do the same so we could see in and hear them. I was to walk around in my boxer shorts and make no. I was repositioned now, lying on my back with my legs up and opened and Derrick moved in. I had ridden his cock for I don't know how long but it was time now for him to do the fucking and I felt ready. His cock felt more like heaven and less like an intrusion as he entered me again. Jon and Kate were on either side of me and were observers now as they caught their breath. I'm sure they got to witness one of the hottest sights as Derrick fucked me into a flow of orgasms like I never had before. He was too cute. He moaned with every entrance. He held his cage. His moans got louder and louder. I felt myself going too. I plunged my cock deeper and deeper till his chastity cage filled with white semen. He screamed in pleasure and fell apart in front of me. I saw and felt his arsehole grip my strapon and watched it pulse as he came. I enjoyed the watching of it so much.Again, I didn't realise I'd started to fuck again. The little buttons were working there magic as I opened my eyes I saw. Her tongue came out to play, finding my own, and they began a teasing dance of their own. She wickedly sucked my tongue into her mouth, held it between her teeth, then released it.Alexa stood and stepped between my knees, then sat on one of my legs, wrapping her arms around my neck as she kissed me again. My arms automatically encircled her, my hands began caressing her back and shoulders. What I could feel under the silky kimono was warm, firm, and very sexy.Alexa stopped kissing me and pulled.
