As we entered the elevator other people started filling in. I stood behind my mother in law as the elevator started to go down. Now what you have to u...derstand is, I have never looked at my mother in law in a sexual way before this happened. It wasn't because she wasn't attractive or anything. But she was on the chubby side (not that I mind or anything) but she was my mother in law! Anyways she had her hand behind her back at the time, and the elevator instead of going up had gone to the. I didn’t know this, so i rang the door-bell. I waited for 3-4 minutes The door opened. A fair middle-aged lady stood in front of me and asked “Yes?”. She was HOT. She was around 5’6, 34-32-34 figure with nice sharp curves, round boobs. a visible long navel .. nice smooth chiffon saree wrapping her figure. I continued greedily staring at her features. Swollen red lips, a sexy face, wheatish complexion, smooth flowing hair.. I was woken out of my dreaming , when she said again “Helooo yes?”... She grabbed Theresa's head and pushed it hard against her crotch, while screaming with raw orgasm.After it subsided, Jennifer sat up and pulled Theresa's face to hers, reuniting their lips. She probed the other girl's mouth with her tongue, tasting her own juices secondhand. Then she pushed Theresa down onto her back and took position over her. Jennifer regarded the other girl for a brief moment. Theresa had straight, shoulder length brown hair, at least she did when it was dry. Her pubic hair. “Shit!” whispered Caitlin, and she slid sideways as I stepped back.She darted out the door, running after her mother.I stood there. I mean, really, what do you do in that situation? Where do you go? What do you say?My mind was tumbling. I felt like I should sit down before I fell down. But, eventually, I sort of wandered out of the door. I didn’t hear any screaming, so I didn’t know where they were. I remember being glad her dad was at work.I found them in the living room, both standing, Hannah.
