Maine jhat se apni pant aur kameez khol di aur unki chut ke samne baith gaya, unhone apna petikot uthaya aur maine unki chut ke hontho ko do ungaliyo se khol diya aur chut ke ander tak dekhane laga tabhi unki chut se bhi mut ki dhar nikali aur mere chehre par giri. Maine apna muh khol diya aur unki dhar mere gale mein lagane lagi, mujhe unka mut bahut tasty laga wo bilkul ladko ki tarah mut rahi thi.

He thought for a second and then he opened his lips and took the nipple in. started sucking on the nipple and reached out with his hand for her other boob. Lisa started moaning.Lisa: AhhhhhhWhile Rohit was fondling with her other boob he kept sucking and nibbling on her right boob. He needed no further instructions.

His tight ass wrapped around my cock as I pushed down on him, hands on his hips now as I started thrusting. Both of us moaning together as we fucked. Looking at eachother time after time as I continued to pound him. Looking down at my cock sliding in and out of his ass, seeing his round smooth ass, it all looked so good. He reached back and grabbed me as he sat up, looking back at me as I had my face right net to his and we started kissing and fucking. My hands came up and ran all over his hot.
