.here drink this."He handed me another glass of drink. It smelled like the concoction Idrank earlier."Umm...what is this?" I asked."This is a stabili...zer...it will finish the serums job. If you don't drinkthis your body might..well....dematerialize, or turn into goop..there isonly a 1% chance you would revert..and I don't think we want to take thatchance," he said to me."Ahhh....1%..." I looked down at the glass... "Well, at least I am aliveright? Ha ha could be worse," As I drank the last of. She recovered immediately. “Thank you Master.” She managed to strangle out. Yves grinned at her distress then said. “I will test you now Carol.” He seemed to think for a few seconds. Then he said “Dog.” With out thinking Carol spun around and dropped to her elbows. With her legs spread, she raised her ass presenting her sex for use. “Very nice child.” He remarked pulling his long massive cock out. “Remember you training Carol while I use you.” He finished with a sneering voice. Yves parted her. I whispered softly into her ear, "Your pussy tells me your enjoying David chatting you up, go back in and I'll bring the drinks in a moment." "What are you up to?" she asked. I was so turned on thinking about another man chatting up my wife. I took a deep breath and told her what David had said about her panties and he'd love to see her in them. I told her the way what he'd said had really got me going. She smiled then told me to tell him that she was wearing the same sort of panties that had. Her relaxed body jerked as he wormed his penis into her from behind. She hadn’t expected him to be able to do this again so soon. Her knees came up, automatically, to give him room to get in deeper, and she arched her back, for the same reason. He continued kissing her back, and letting his hands slide all over her, as he thrust gently.No orgasm threatened. This just felt marvelous.Then he was manhandling her onto her hands and knees again, his hands on her hips. She didn’t have the energy to.
