Chapter 736 Neuro Submission Transmitter: 160

"Oh fuck!" she breathes. "Keep doing that!" I rub my thumb in a circular motion over her love button as I drive my hard shaft up into her fiery pussy. We are both bucking feverishly and I'm getting awfully close to shooting my load. I glance at the video screen and it looks like Susan is getting ready to climax, too. I want to cum with my sister but I don't want to leave Tracy hanging. I work my thumb faster on her clit and she goes crazy on my cock, rocking and bouncing like a wild woman. "I'm cumming," she yells, "Oh fuck! I'm cumming!" I pull my hand away as Tracy lunges forward, tightening her pussy muscles around my cock and jerking wildly through the first wave of her orgasm. On the video screen, Susan is spasming against Danae's face. Awesome! I trigger my own release, shooting another load of cum deep inside Tracy's pussy while my eyes are glued to my sister's tit's heaving up and down on her chest. I watch her orgasmic facial expressions gradually transition from painfully gnarled to blissfully relaxed.
