I placed her left hand on Ian’s crotch and the other on mine. She began to rub us and I began to feel het breasts, I encouraged Ian to do the same.W... both began to kiss her and it was obvious she was turned on. Not wanting her to cum too early Ian and I stood up, me behind him and I started to undress him, facing Joan. I undid his shirt and after removing it i began to play with his nipples.He was squirming as I undid his jeans and pulling them down exposing his member to Joan’s view. She had. All she could say was, “Oh my god” while breathing heavily.I broke the kiss to take my t-shirt off. While she was staring at my chest, I held her in my arms again and started to kiss. I caressed her butt. Ah! I loved it. I totally admit I was just crazy for it.I pulled her top off and picked her up. Meanwhile, my hot colleague had wrapped her legs around my waist and arms around my neck. I kissed her like that for a few minutes with one hand around her waist and one grabbing her butt. I made. "Are you my ho?" I demanded."Yes master," she replied gasping for breath.I brought it down again."Tell me you're my ho and that you want your pussy fucked," I demanded."Please master, fuck my pussy," she whimpered as the next blow descended between her massive globes striking her neither hole. Her cunt was glistering from the wetness and I knew she was craving this. I brought the pointer down again and again till I reach the final tenth stoke. Her ass was crisscross fairly well and she was. The plan was to drop my sister off at work and head to campus. Until, a naughty and erotic plan lit up in my head. What if, after all this time, today was the day i dress up. It seemed brilliant, campus would be practically empty- with the students on holiday- lectures would be around, but that aint such a biggie, they'll never know who i am. While my sister was eating, just before we were going to leave, i sneaked into her room to grab a few clothes. Feeling extra naughty, I decided to put on.
