There was a drain in the floor that they could use for a latrine.This wasn't enough beer to do more than relax everybody, and they had a pleasant rest...while they waited for midnight. Some time was spent in checking over their equipment. This wasn't really necessary, but it did delay the onset of boredom. Dick reviewed the plan with everybody, reminding them that they were not to kill anybody, unless it was absolutely necessary to preserve the life of a comrade or to further the mission.. I looked back at him and licked my lips. He was just what I needed and I could feel an orgasm on the way. After two minutes of Joe's huge cock frantically pounding me, my muscles spasmed and I began to groan. Joe had done well to last this long, but the excitement caused by my groans was too much. He gripped on to my waist and forced his cock all the way inside. At that moment my orgasm reached its peak. Joe's cock spurted out wave after wave of cum, and as my vagina muscles contracted, his. The events of yesterday flashed through my mind and I immediately had the urge to go up there and look around. I silently walked up to the attic door and opened it.. I didn't hear anything, so I started walking up the stairs. I heard Lori's voice coming from her bedroom and I stopped. My curiosity wouldn't let me be- I had to see if Ryan was with her. I wasn't physically attracted to him or my sister.. But the thought of them having sex interested me. I slowly walked up to her bedroom door,. He was getting faster and faster so I asked him if he wanted to fuck me, he said he would if I was fine with it which I was more than happy for it to happen. "Just as your about to cum, pull out and stick it in my mouth, suck me first and make me cum near to when you cum" I asked politely and he gave me a caring smile back. I seriously thought I was in heaven, how could a boy who was perfect have sex with me? At that point I didn't really care about justifying it. I felt my dick enter a warm.
