I started thinking about taking her doggy style and my cock started to stiffen. I leaned forward my hand on her thigh and kissed her behind the ear sh... moaned lightly and almost dropped her drink which she put down and came back and kissed me hesitantly. I kissed her kinda hard and she responded eagerly. I worked my hands under her shirt up her back to her bra, I broke the kiss and moved my mouth to her ear. Renee was rubbing my cock through my boxers, and I whispered you know what I want she. I had an instant boner and couldn’t​ hide it in my trek pants. Shreya saw my boner and smiled at me and said “What’s so arousing in that?”. I said “she has amazing boobs and the cleavage is irresistible”. We were pretty close and such talks were not a big deal between us but what happened next was something I didn’t expect. She suddenly stood up and said “I have better boobs than her” I laughed a little and she was pissed now. She had a thing that she couldn’t control it when someone didn’t. She used my balls to control how close I was to her face, if I tried to pull back, she gripped my balls tighter and drew me into her mouth.After just a few strokes, she must of known she had complete control of me. I began to move my hips causing my cock to soar in and out inside her mouth. I was amazed at how much of my cock she was able to get into her mouth on each stroke. I could feel her fingers letting up on my balls, yet massaging them gently as she sucked away at my shaft.It didn’t. We were there to learn andlearn we did. Obedience was indeed the rule. Deliberate errors weremet with severe punishment. I received a heart tattoo on my ankle forone offense, a pink butterfly on my shoulder blade for another and arainbow tattoo just above my buttocks for a third. Errors during honestattempts were met with encouraging remarks and additional repetitions.At first to avoid punishments, and later to earn praise, Charlie and Ibegan to put forth our best efforts to learn ballet. .
