After 15 minutes I felt that I was falling from sky to earth and my pussy was flowing hot liquid first time. I understand that this is my first orgasm...and what I was doing is called masturbation. I washed my hands and took shower once again. Then I made dinner for myself, took dinner and gone to bed for sleep.In next day I called Rinku in lab in his leisure period. I asked him what you feel about me. He replied that you are very good professor and I enjoy your class and other things he. "Yes master," I moaned as I complied with his wish.And then ... nothing. I could hear him sipping his coffee, but I could not see his face. I couldn't read his expression. I couldn't tell what he was thinking. I couldn't even tell if he was looking! I felt so foolish. Kneeling there presenting my bottom. I felt like furniture. But, MY GOD, I was horny!He began to stroke me with one hand and I sighed. He squeezed my cheeks and stroked my thighs. "Mmm, soft" he said, in a tone as soft as my skin.. He is shaking it, his lips pursed, but he stays in position, bent over, bottom presented, waiting for the next stroke even as a tear slips down his cheek. Zoe was on fire, excited, exhilarated even, and feeling so turned on. Mike was accepting being caned by her and she was finding it so sexy. She tapped his bottom again, eager now, wanting to make sure the next stroke was as hard, maybe even harder. Yes she was sure Mike can take harder, will want it harder as he always pushes his boundaries.. Derek, you get on top and then Brandon can suck you while you suck him”. Immediately they spun around as she told them and began mutually sucking each other.Derek heard a noise but he was too busy to look up. He was engrossed in the moment. He felt the bed move and then something pushed against his anal opening. “You know what sucking cock is like” he heard Sandra say “now know what anal sex is like” and she rammed a lubricated strap-on dildo into his bum hole. “OH FUCK” Derek screamed, his.
