The reason is simple. A hard cock in Jennifer's mouth, or in her hands for that matter, makes her uncontrollably horny and she feels compelled to stop...sucking it because she wants it in her wet pussy.Since I had just returned from a seven day business trip to Germany, I was extra aroused. Jennifer slipped off my underwear and lightly ran her fingers over my balls. With her other hand, she grabbed my throbbing cock and stroked it. She then asked me how I would feel if she was doing this to. At that time I didn't really mean for it to happen but I guess my cock has a mind of it's own at times because as the people were shifting the buldge in my pants starting growing to the feeling of her hands there. The doors opened and two people exited, at this point I thought for sure my mother in law would adjust herself now and remove her hands from touching my crotch. As people started to spread my mother in law instead of moving forward to make space in between us, I instead felt her hands. He reciprocated and kissed her back content to let her be in control. "Clothes off now!" She demanded leaving no room for debate as he started stripping watching her slid her dress off her shoulders suductivly.As he slid his boxers down his legs she grabbed his six and a half inch member and started to jerk him slowly he moaned savoring the moment. Then suddenly she threw him on to the bed stardiling his face and grindingnher dripping pussy onto his lips. "Eat my pussy!" She demanded. I was so embarrassed I couldn't respond, and tried again to hide."Awww, she's shy," cooed Clair, beaming at me in the way women do withsmall children.Without even glancing at him Amanda asked Magestone, "Who is she? She'sadorable."What was making this situation worse for me was that before I had metSarah I had dated Amanda, and now all I was as far as she was concernedwas a pretty little girl."This is my half sister Jessica, say hello to Amanda, Jessica." Magestone was well aware of my history.
