Next I printed out the three articles on incest that I had found. I hid them in my back pack. The folks never looked in there. Besides, it was almost ...lways with me.I had just finished when there was a light knock on my door. I closed down the computer and unlocked the door, "Come in". It was Jen. I tried not to show how nervous I was."Hi, Sis. What's up?" Hi, Jeff. I wanted to ask you some questions about what you've been doing to help me with my tests."Uh oh. Careful. This could be. I asked her “What are you looking at?” She giggled and said “Wait, let me get more comfortable” and proceeded to remove all my clothes. She took off her blouse top too, revealing the slip beneath through which I could see her black bra. I could make out some small tufts of hair in her armpit too.While my eyes were devouring her she proceeded to give me a serious body lick all the way down. I mean, Really licking, long wet strokes of her tongue down my neck, shoulders, chest, nipples, navel,. The mouth relented on my cock, he knew I was going to cum, I was flush against the stall wall, with my cock and balls fully through the glory hole, with my stocking'd feet cold on the concrete floor, my chest and the right side of my face on the cold stall wooden wall.I sat back down on the toilet, my head spinning, hands still on my legs and cock, and then the biggest cock I had ever seen nudged through the glory hole and the words "Your turn" were uttered, I was terrified, this wasn't me was. There may be slight inaccuracies in wording of what was said, but the events are true, and I will also add a small part at the end saying what I think happened. I appreciate this may make some people hate me, and I have to admit, this wasn't my finest hour (or hours).Roughly a couple of months after the events of the night my ex went out with her friend, we were still going out every weekend, and most of the time, getting really drunk. We would always have a good night, frequently meeting.
