I was not in the mood for any tom-fuckery from my sister Jenn, but as you can guess, that's the day this story is set in. I had barely even walked in ...he door when the berating began..."Hey kitchen bitch, Sam left you a gift in front of the dishwasher and dad wants you to clean it up" Jenn lazily demanded from the couch with her back to me. Sam was our Boston Terrier puppy that Jenn just had to have despite her inability to show affection for anything but herself. I glanced over and sure. The dress was sheer and tight around her waist and until knees. I was in shorts. I got an instant boner she noticed it and she said, “You, dirty boy.” I said, “I want you to be my dirty friend.” We were both sitting on the sofa and we are feeling like a newly wedded couple.I got the courage to ask, “Would you mind if I kiss you?” She was confused and said yes and closed her eyes. We started kissing, sliding our hands across each other. She really liked the way I was kissing her. She never had. I massage her shoulders and neck for sometime with oil and are constant relaxing moans were exciting me and getting me a hard on.After massaging her shoulders and neck she heated and comfortable and I asked her to remove her sports bra and unhook her padded bra to my surprise she told me to remove it by myself and I was excited,i saw towards her husband and he was falling asleep so I took the advantage and removed them by myself.After removing her bra and sports bra I poured some oil on her. At once I squirted and spreadmy sperm over chest and belly. One spurt even hit my throat.When mother saw that, she began to laugh as high as a bell, unfolded a paperhandkerchief from her skirt pocket and wiped away the sperm puddle on my throat. "Shall I wipe away the rest too?" she asked, and before I could think over this,a "Sure, yes" escaped from my mouth. Only then I realized with delay that she hadto touch my willy for this of course. She worked down from my chest, put thetotally sticky.
