His arm had no hair and was no larger than before, but the skin was turning a dark brown. This wasn't his body!He looked up to see Quince watching in ...fascination. "Why?" asked Paul, on the verge of tears."You never knew what was going on here, did you?" said Quince. "Too wrapped up in your own problems. You're being changed by a stronger version of the virus. We had to see if it could work."Paul was too terrified to speak as he felt the virus make its way up his arm and across his shoulder. I licked the base of her head with playful little flicks of my tongue followed by one light, slow lick up her entire shaft before wrapping my lips around her dick and before you know it I was sucking her dick. If there was one thing that seemed less likely than my sister sucking my dick, it was me sucking hers. And goddamn, was I glad it was happening. And apparently she was too, because in the lightest, breathiest whisper, she said, “Alex, that feels so good…” Which she didn’t really have to. After finishing with her back I suggested I could give her a “butterfly” massage on her buttocks. She agreed to this, so I pulled her bikini bottoms down to the top of her thighs to expose her bum cheeks and started the butterfly massage and by now I was feeling a little horny so I did it unevenly on alternating sides so that her cheeks rub her slit lips across themselves. I wanted this to give her a good feeling in her genitals. I then started massaging her legs from her feet to finish up at. You and me, us. Joyce said you'd probably find it easier with just me, instead of having to deal with both of us, and then you still having to make another choice."I made no further comment, instead I turned and carried my bag up to my room. I went down to the children's play room and spent time with all eight that were there. I couldn't help feeling sad about the other four. I wondered why I couldn't just be happy about the eight I was there playing with and talking to? I knew it had to do.
