MICHAEL<br/><br/>Heck, I thought mom would have put me to work teasing Rachel with her, but with a glance at Sarah, I realized she was doing exactly that.  Poor Rachel was going to be in a sad state before too long, denied all the fun, and forced to watch hungrily from the sidelines.  I leaned to kiss Carmen's shoulder again,<strong>"Of course, Mother.  Anything to help out."</strong>I allowed my right hand to stray down her back, to cup, and gently squeeze one firm cheek of her ass, just copping a quick feel, as I turned my attention to Sarah, who was already lost in a small forest of arms, legs, and cocks, which I would soon add too.<br/><br/>Getting into position would be a little tricky, and I didn't want to dislodge my Father, or little Brother from their attentions, so I mentally planned my route under her, while sitting next to sweet little Sarah.  I reached beneath her, and cupped one swaying breast,<strong>"Hi Sis, you have room for one more?" </strong>, then gave her nipple a firm pinch, and gentle tug, before laying on my back beside her.  My cock had already began lifting in subtle jerks at the delights Sarah's body promised, as I wriggled, and maneuvered my way beneath her, all the while trying to stave off the stupid joke that was trying to run it's way through my mind, (what has 8 legs, 8 arms, and 3 cocks?  Sarah!).  Yes, it was stupid, but my mind loves puerile jokes.<br/><br/>In position, finally, little sister tits, and wonderfully erect nipples rubbing deliciously across my chest, I turned to look at Rachel, as I took my cock in my hand, and rubbed it's swollen head between the slippery wet lips of Sarah's pussy.  To me, she looked tortured, which I'm sure was what my Mom intended.  Lifting my hips, slowly, I pressed my cock into Sarah's cunt.<br/><br/><br/><br/>
