Anusha was thin, about 5’6”. She had an athletic body. Her boobs were not so mature, but pretty cute. The really eye-candy for me was her arse. He... figure was 34-29-37. The curvature on her back-side was really a turn-on for any man. Generally they would sleep with my Mum in a room and I would sleep with my Dad in the other room. The monsoons were at the peak and my parents had to urgently go to Pune for some work. They were supposed to return the same day but it turned out that they would take. Damn that sheer silky under wire bra! I looked down at my shivery nipples and there they were, hugely erect and jutting out my thin ribbed turtleneck sweater like jumbo peanuts! The girls smiled back knowingly, then turned back to the screen, but some evil person beside me sneaked her right hand up under my arm where the others couldn’t see and cupped my right breast. All our eyes sparkled as we watched a willowy, sort-haired brunette poke and tease the pussy of an anxious, belt-bound. She stood up and dropped her yoga pants and panties. She sat back down, this time her hand clutched my cock, aiming it towards her pussy. Next thing I knew, I was inside my Stepmom. She bounced on my penis, her ass making loud clapping noises in the process. The two of us moaned. I was shocked that this was happening. She continued bouncing on me for 5 minutes and then stood up. She went to a flattened bench and bent over, her breasts squishing out of the side of her bra. She stuck her ass out,. I had no idea we were going to have sex, I just wanted to explain what you and I were joking about. Dont worry, I will not say anything, but if he had seen you he would have been deeply embarrassed. He did not realize the door was left open. I closed it before he noticed. She was still upset so I hugged her, but that did not help. She started to cry. She was shamed by her tears and went to the bathroom. I sat and waited for a few minutes. When I knew she was no longer crying I went to see if.
