I soon had another mouth full of cum.I made it thru the morning classes by sucking off two boys after each class and then sitting with my mouth full o... cum for the next period. Lunch time finally came and I remembered Mistress said I had a special thing to do. I was afraid to find out what it was.I was on my way to the cafeteria and knew not to stand in line. So, I just went to the back of the room and stripped naked. I still had cum in my mouth and couldn't swallow until Mistress told me too.. “I don’t know, but if it does, I want to be ready.”We chatted on for another half an hour, mainly about school and friends, who were going out with whom, who had finished going out, all that sort of stuff, before they all drifted off, and I got myself another coffee.As they left the café, I pulled out my phone and started thumbing through my contacts list, thinking I’d ring round a few of the gang and see if I could persuade some of them to come out. After a few minutes, I put the phone away,. After about 10 minutes Brownie pulled out of me as a bunch of cum leaked out of my asshole. I got up and walked to the back where Blackie was. His cock tip was showing also. I picked a corner where I knew no one could see us if they walked through the alley and got on my hands and knees.Blackie walked around behind me and quickly got up on my back gripping me as he began to hump. Again I moved around until he was able to find the mark and thrust into me. He was gripping me for better position. Kelly saw her breasts were small, with nipples that rode high on her chest. Her stomach was flat, but her cock was a sight to behold. It had continued to grow in anticipation of it's soon to be encounter with her. As Christine walked over to her at the window, her cock swayed from side to side, literally bouncing off her thighs. Kelly noticed Christine's thighs were powerfully built, along with a very rounded set of buttocks. The way she was built, she could have been a track sprinter.Christine.
