Chapter 190 Sister Sucks Sleeping Sibling #4

Jill looked very seriously down at us and replied, 'Andy, really; go ahead. I want to watch. Fuck her.' Jenna looked at her sister, smiled, and looked back at me. She started moving again and guided my almost-but-not-quite limp dick back into her cunt. She moved her hips back and forth until I felt the blood rushing back to my cock. Jill watched intently as we resumed our fucking. My little sister bounced up and down on my dick with renewed fervor. Soon we had resumed our previous rythm. Jen began grunting with every in-stroke. 'Yeah, that's right,' Jill breathed. At first, I sort of felt 'on display'; I'd never had sex in front of anyone before. 'Yeah, Jen, fuck him...fuck his big fat cock...' Her words spurred me on. As my big sister watched me and my little sister fuck, I became more turned on than ever. Jill looked on with an evil look as we slammed away at each other. Jill took a few steps back to take everything in and then began stripping out of her clothes.
