"This is all I've been thinking about all day long. C'mon Noah, more practice," and I followed her back to her room, as I had many times before, but t...is time for a whole new and exciting reason all together.As soon as we were in her room, she started taking her clothes off and was soon standing before me completely naked. Completely naked and beautiful, I might add."Noah, what's wrong, you still have your clothes on." Uh, well, you know, what we're gonna do, maybe we should kiss first, you. The only sounds I could hear were my heartbeat, my panting and slow heavy breathing from two strangers. Out of nowhere, a stunning blow rocked my head sideways, I felt the sting left by the backhand of the stranger and was in shock. Then words in a gruff London accent. "I told you darlin', you're ours. We permitted you to moan without askin’ but didn't give you permission to cum. We can't ‘ave you breakin' the rules. Now you won't moan or cum, you understand?"With that, a ball gag was shoved. I went off into the bedroom and thought to quickly get changed so before my sister came out of the shower. I took off my back pack and threw it on the bed, I took off my top and looked down to my pants, my cock was still erect, throbbing and wanting to rub and fuck something. i thought back to my sister, half naked in front of me and instinct kicked in.I jumped out of my clothes and started to jack off. the thoughts of me and my sister at “it” like animals made me extremely horny I was sit it. She suggested I do a reclining pose, which was agreeable to me. I adjusted my self on the throw lying on my back turned slightly on my side facing the group. Lucy made some adjustments with my arms and legs for a more aesthetic look to the pose. It would be a 45 minute pose with a break for me at 20 minutes. My cock was still swollen when I assumed the pose being in the reclining position it was positioned upward, the underside visible. I was aware of the tightness in my scrotum as my balls had.
