'No, I won't manipulate people with them anymore,' I thought right back at her vehemently.'You're not manipulating her, your helping her. Do it, or I ...on't help you with the demons.'I knew the threat was an empty one. She had to help me, or we were all dead. Despite knowing this, I decided to help mom. If only Lela's people hadn't abandoned us, leaving us as bait for their escape. I touched Summer's hand, so that any switches I made could only be affected if I was with her. That way I wouldn't. I was trying mybest to cum again so she could get a mouth full of fresh, hot cuntcream. I was getting close, but I had to pee. “Just a second,sis. I have to pee.”“Go ahead.”“Pee how?”“Sure, let me taste all your juices.”What the hell, I thought. I really had to go. So I let a smallstream flow out of me. Lisa continued to lick and suck at my cunthole as my pee poured down on her nose and into her mouth.“Come on sis, you can do better then. Suddenly but gently I felt her fingers on my cock. I couldn't believe it. I didn't know anything could feel so good. Her touch was light and yet at just the right spot. Her hand wasn't moving but it didn't need to. I couldn't help myself and came spontaneously. My jism went all over her hand. She gently took her hand away and wiped it on her pajamas.As I thought back on it later, that night marked a turning point in our relationship. Always friendly and cooperative, we now treated each other. I just wanted to let it go and fill Joanne’s ass with cum. Joanne was moaning and enjoying it. She finally looked back over her shoulder and said, “Pound me, baby. I need to be pounded hard!”I complied. I grabbed her hips and started forcefully thrusting my dick into her; burying it to the hilt and then pulling out until just the mushroom head was left inside. She kept moaning. I could feel someone playing with her pussy, rubbing her clit to get her off. I couldn’t tell if she was doing it to.
