Next Thursday after my third period, I faked stomach pain and took leave for rest of the day. Once out of school loitered around for an hour and waited at the backside of the bus stand in front of our apartment block. The gate to our apartment block was visible to me. After fifteen minutes I saw my maami and Pratip alighting from an auto rickshaw. After settling the fare they went inside the apartment block. I waited for 10 minutes and then started for my apartment.
I pressed the calling bell on reaching my apartment. I could sense someone watching through the door hole. After a few minutes the door was opened by my maami. She greeted me with a smile and asked how come I am so early back from school. I replied that I wanted to learn all about sex by watching my cousin and my mother. She frowned. I looked at her and for the first time I realized how sexy she is, fuller breast and hips. I developed an instant erection. Noticing the bulge in my pants she gave a naughty smile.
I proceeded to my bedroom and changed. Then i approached the master bedroom. I could hear the voices of my mother and Pratip. I pushed the door lightly and it opened. My mother was in her blouse & petticoat and Pratik in his briefs. They were sitting on the bed and discussing.
My mother said that they need to be careful as I am aware of their incestuous relation. Pratip said that she should try to convince me not to disclose their relationship to anyone. My mother replied that this is possible only if she has sex with me. I was surprised to hear that. Pratip commented that she should please me sexually, having sex with one's son is very pleasurable. She asked how did he know. Pratip said that 's how his mother feels when he makes love to her. My mother asked who pleasures him most in bed. He said off course its you, I can fuck you the way I want and whenever I want. Saying all these he embraced my mother and kissed her. They kissed for for a long time. I could see a bulge in Pratip's brief. Pratip said something in my mother's wife.
My mother immediately stood and then knelt in between Pratip's legs. The she pulled down Pratip's brief and his penis sprang out. Almost my size but smaller in diameter(7-8 inches long and 2 inches in dia). She first jerked his penis with long strokes of her hand and then engulfed it in her mouth. Then she started to suck his penis. She will first move backward and then forward. This continued for almost ten minutes when Pratip's body stiffened and he moaned Uuuuuurrrrrrrrggggggggg. My mother withdrew completely, pratip ejaculated five to six globs of semen, which landed on my mother's breast. She stood. and wiped her breast with paper napkin, then lied down on her back.
Pratip lied on my mother and started kissing her lips. His hands were kneading her breasts. After 12-15 minutes Pratip slid down, pressed her breasts hard and started sucking and licking the breasts alternately. Now my mother started moaning.
