His eyes magnetized to her breasts, they were shaking lightly, her chest moving with nervous breaths. He sat up and pulled his shirt off then peeled h...s shorts down his legs. When he lay next to his sister again he was nude, his erection long and strong, pointed at the junction of her legs. She was watching him raptly as he took her thong and pulled it down, she lifted her legs and kicked free of the tiny garment then reached for him. He rose up and over her, she splayed her legs then with. Kumar knew he couldn’t last long. He felt the pressure, the impulse build-up inside of him, multiplied with each wet kiss, each stroke, each lick. Yet, he tried to hold on, using all his willpower to keep it at bay.Mamta only increased her intensity. Her grip on his penis tightened, her head moved up and down his penis at terrifying yet exhilarating speed.“Mamta, I am…” His semen burst through and into Mamta’s mouth, the thick ropey seed forcing its way down her throat. Kumar himself felt all. We were both panting hard.She recovered from her orgasm and then wiped both of us with her clothes. Then she walked away naked towards the kitchen to cook lunch for us.I was also hungry. I went to the kitchen and held her from the back as she was cooking. We were smooching then and there with clothes on. My dick was rubbing her ass, just a few hugs, and kisses.Later we had lunch together. When she gave me the glass of water, I held her by hand and made her drink some of it. Then I sealed her. I said yes and he said not to be afraid and he came over and got in the shower. This was the first time anyone ever saw me naked since diaper changing times. I froze as he got in but could not stop looking at him and could not cover my self up. After he got in he started to rub my shoulder and then worked his way down to my throbbing cock. He was able to rub my cock with two fingerers and ran my hand gingerly around my ass until I was cumming. Then he took my hands and used them to rub his.
