My heart started racing since I knew it was possible to do, but it wouldn’t be as discrete as me fingering her with my hand covered by a blanket. I ...ooked around the busy and the other students seemed preoccupied so I looked at her and said “okay”. We switched seats so that I was closer to the window and she was next to the isle. Roselia positioned herself to look as if she was laying her head on my lap and threw the blanket over her and fixed it so nobody could see anything lower than the mid. Since middle school. As Mercedes and myself entered the room, Amy told me to close and lock the door. My heart sank, I have never been so scared in my life. Even though I had no idea what was about to happen I knew it wasn't going to be good. Or maybe it would be good? I had a million thought running through my mind. Amy told me and Mercedes to take off our clothes and Mercedes asked her why? Amy responded "I am going to teach you how to be real sisters". Amy told me to sit on the edge of. “What’s this all about?” She licked her lips, “whatever you’ve got planned has my boy so wonderfully excited!” With her pink tongue she caressed my throbbing helmet, then grabbed my ass with both hands and swallowed me whole. I could feel the back of her throat open up and her teeth run along the underside of my shaft. She rocked her head back and forth with love. Struggling for control of myself, I shook my head and opened my eyes. She looked up at me and smiled before methodically going back. Matt started yelling, how great it felt fucking me and that he was ready to shoot his load. In the past I was happy when the guy was ready to shoot his load but not this time. C was enjoying this too much to have it end so soon. I lifted up letting his cock slide out and quickly pinched his cock just below the head a little harder than I needed too. He yelled at me but I didn't care, I told him it was to make him last longer. I didn't know if it really worked but I really enjoyed doing it.
