It was a residential area and so was very peaceful. It did not take much time for gradma to trust us as we both worked in a well known MNC and was hel...ing her on free time. The heroine of the story is her grand daughter [Teena], who caught my attention the day I saw her on 1st floor. She was always doomed in her own world with medical books all around her. Yes, she is a future doctor. As my observartion goes, she hardly meets eye with any guys coming across her on the road. She simply avoids. I mumbled, reaching out to press the button again. “That tops it!” she exclaimed, her voice trembling with anger, then leaned back on the wall and sighed. The elevator trembled for a brief moment, then plunged down. I felt my body getting light as a feather. My feet took off the floor and everything before my eyes grew blurry. The girl was screaming, I saw her flailing her arms like a puppet. And then a monstrous hit ensued, parts of the torn boarding grazed my left cheek. I collapsed like a. Then I saw my parents doors were opened and light was on and they were start to having sex. They were still wearing clothes. I watched them having sex whole time for more than 2 hours and I was stroking my dick while watching them. My dad fucked my mom in every position possible and she also sucked his dick like a good wife and at last my dad put his sperm in my mom mouth and she spit his sperm on floor and both started laughing. Then I was tired as it was night so I slept and planned to wake. We had coffee later which she was talking about my exams, results and further studies and she was advising me but the only concentration of mine was fucking her. I taught of just pulling her and started smooching her tear her dress.After finishing my coffee I went to take bath were I saw her panties and bra hanging I took it and started sniffing it and jerked twice with huge loads of come. Tried many ways to seduce her indirectly but nothing worked.Few years later.Now she is married to a rich.
