That was a good question. "Then maybe I shouldn't use it at all." I looked at Yvonne and how the borrowed tank top stretched to hold her increased bus.... "Well, I could use it to try and give Yvonne her figure back."She looked down at her chest and then hugged it with both arms. "No! If you change me back then I won't have the figure you prefer." She looked at Nadia, Erin and Renée to point out her meaning.The others chuckled. I didn't think it was that funny. "I only suggested it, Yvonne,. She kept cumming, her legs shaking like crazy, I thought her legs were going to give out soon, but Charles helped her to stand there by wrapping one arm around her waist. He did not slow down his fucking he just pushed his dick into her harder and faster. Tamara was still cumming and screaming as Charles let out a loud grunt, he pushed his cock in deep a few times and then held his cock in her for a minute or two. He gave her about four or five more deep pushes and stopped grunting. Cum dripped. "I could sense Cynthia's rising excitement as she thought about it."Well what are we waiting for? Let's get to it. We'll need several different species including horses of course." Not so fast Cye." I touched her arm. Jenny and Vee must agree to all this. It will be them that will be affected. There is also the species virus aspect. If we create animals compatible with humans, we might also create viruses that can cross the genetic boundaries. In fact it?s almost a certainty." That shouldn?t be. ..I didn't realise I'd slid my hand inside my pants at this moment. What's a man to do after all? And it was so easy with no underwear.My neighbour didn't miss a thing. She was looking at me and mouthing: "Get it out for me, dear."I didn't need any persuading. It felt the biggest erection I'd ever had. The management evidently knew what they were doing sitting me here. Again my neighbour leant back to show me to her friend. Quietly they made me sit between them. 'Left-hand Lady' took my dick.
