She took those items from me and asked me to come in for a cup of tea. She put the stuff on the floor and while she bent over, I could see her green p...nty on top of her jeans. It gave me a huge boner, I discussed about Usman with her and we had a nice decent conversation before I left. I do not know how I controlled myself in there but I didn’t want to put myself in any kind of danger.Three days later, Usman came back and he thanked me for helping him out. We were chatting over a cup of tea. Since Mr. Harris's Office was outside down the hill, on the backside of the school we felt his office should be first. As we walked out side I noticed the huge wall and asked, "what is that, Sister?" Pointing to the wall, Sister said "Oh it's the auditorium," as we walked down the steps, I then asked 'Is Mr. Harris's office down here behind the auditorium?" She looked at me and said "are you thinking what I am thinking?" I said I think so, I bet his office is on the other side of the dressing. You say youve never done anything like this before? David said with a grin, confirming what Id already told him. No, only a bit of talk thats all, I replied as I helped Margie onto the bed and lifted her knees and spread her legs. David took a tube of lubricant and squeezed a bit onto my wifes already wet cunt, then massaged it around letting his fingers slide sensuously through her cunt lips. Youre already nice and juicy and hardly need this, he laughed as he played about with my wifes cunt. . Her short speech had obviously been the go button. And I knew he had no intention of stopping. The musics beat only adding to the rhythm. I don't know how long the songs lasted, where they stopped or began, cause after my second drink it all became a blur.While watching Emily slowly reaching around and feeling his cock through his jeans while staying pressed up enough to him to not be too noticeable, I was interrupted by Anna. She was apparently invited back to her new friends place for a party.
