I realize that Sara has cuddled up closer to me than usual & that my morning wood is now lodged in her ass crack. I kind of like the feel of my hard c...ck being in my sister's crack, so I begin to slowly and gently start moving my cock back and forth in her ass crack. I take my hands and start caressing Sara's breast, tweaking her nipples with one hand, while the other is creeping down between her legs towards her sex. I get the response I expected, a low moan from deep within her and a shiver. As she doffed her tank-top, I could see her tits straining inside the plain white bra. Without removing her bra, she slid her running shorts down her firm legs, exposing her firm ass and blonde muff. The tan lines from her French cut bikini made her look even more naked. She reached between her breasts, and released the catch on her bra. The full melons popped out, the small dime sized nips a bright coral color. Mary cupped her full tits in her hands, massaging them where the bra had cut into. Between His legs... and staring... myopically... at His ratherlarge... and sweaty nutsack... with His testicles... still... constantlychurning... and writhing... in their dirty sack... even in His fuckingsleep... and as you place one silky palm... of your left hand...gently... on top of His naked thigh... to try and push yourself away...at least... to try and escape His crotch... just enough to get... Hiscoarse... and crinkly... black pubic hair... out of your nose... withoutwaking Him... and. Oh God! he's found out ... was her first thought but then shedismissed it, realizing that his voice sounded quite friendly. She knew if Ronnie everfound out that she had sucked his son's cock he would probably kill her!"Come in Ronnie," she called out."Thought I'd bring this bottle of champagne over for us to celebrate my birthday, thatis, if you don't have anything else to do," Ronnie added quickly, noticing how lovelyhis sister-in-law looked this evening. Especially lovely, all soft and dewy.
