Of course I pressed her for exactly what he did and finally she told me he had touched her tits. My cock immediately grew hard; it was a good thing t...hat I was also laying front down on her bed. I asked her to explain but she told me she had already told me too much, that it was personal. I then pointed out that we had agreed to have sex only with each other and that I was upholding my end of the agreement and so I expected her to be up front and honest with me. With that she drooped her. I had a rather interesting encounter with my sister yesterday and it means so much to me that I have to share it with someone. I was taking a shower at my parents house in preparation for a job interview (I keep nice clothes at their house). My mom and my sister returned from their body pump class right around the same time I finished my shower. As I stood in the bathroom with my towel wrapped around my waste I got ready by brushing my teeth and shaving etc. I heard a knock on the door, I made. “And what are you going to do about it?” I asked, playing along with him “You’re just going to have to see about that, miss.” “Is that supposed to be a threat?” I asked as I placed the palms of my hands on his chest. “It’s a promise,” he replied deadpan. I didn’t know what he was thinking, but I knew I’d find out before long. ************************ The band ended their song and the leader announced it was just a few minutes to midnight. We went back to our table to see our glasses filled with. During next round she was a bit hesitant to remove her shorts but seeing that we would make fun of her for being coward she went ahead and removed in shorts inside the bed sheet only and threw her shorts out.In the third round she asked us to finish the game but we were not ready, so she said that this would be the last round and we agreed. We all were expecting that she would remove her bra but instead she remove her panty in such a way that we were not able to see anything inside.We insisted.
