I am 21 years old working in a office which is 50 kms away from Chennai, medium complexion, weighing 65 kgs. My sister is 30 years, married (widow), h...aving a male child of 2 years old, medium complexion, sexy body, big breast and weighing 60 kgs. After my sister’s marriage 5 years ago, she lived in Trichy with her husband till 6 months back when my uncle was met with an accident and die on the spot. Then my sister came with her son to my parents living in Chennai. I stay in my bachelor’s room. She moaned, then broke free. Her hand came up and squeezed my straining hard on. Gosh that’s like a rock, she whispered huskily. I didn’t say a thing, but unzipped my trouser. She leaned forward and kissed my huge erection through my bursting frenchie. I couldn’t hold myself any longer. My hands reached down and squeezed her full breasts through her shirt then, I opened the first button, and saw the straps of her black bra against her lovely shoulders. I slid my hand underneath the bra and. She came on top of me, held my dick in her hand and guided it slowly into her wet horny pussy....Aah, the tightness, i cant tell you how wonderful it was. She was as tight as my ex girlfriend who was just 19 when I last fucked her.'Rita!' I moaned as she started her slow rhythmic motion over my cock that was rubbing tightly against her pussy walls. After 3-4 minutes of slow sex she had her first orgasm. It was like she hadn't had an orgasm since ages, she was sweating and countinuously chanting. But as I pressed her boobs harder I think she was turned on completely and she opened her legs and I got my fingers slowly touch her panty and I pulled it aside and I noticed she was very wet and she unloaded her cum before a short time. Now I was rubbing her pussy gently and with passion with my head looking outwards. And she again started pressing her thighs with my fingers on her pussy.This made me feel her entire heat and I started rubbing her pussy faster and faster, now she was unable to.
