I knew in the back of my mind that something fun was going to happen and I was kind of looking forward to maybe doing something that I had always thou...ht about but had never really done. Mark came into the room with a blind fold he had made and placed it over my eyes and tied it in the back. I could'nt see anything at all at that point and I started getting a .little worried that they were going to pull some kind of prank on me.I laid on the bed and heard all the guys come into the room.

Well, you would if you could talk," he whispered, laughing loudly as he went back to stroking himself.I cringed. I was filled to the brim already...there was no way he could stuff more than 3 inches more.
