We were kissing passionately on the couch, but my mother however stopped my wandering hands. Every time I would touch her breasts or move my hand too ...ar up her leg she would move it away. My mother was giving the hottest sexual experience of my life yet she being a big tease as well. Finally you could hear the ending credits music play and the movie was over, my mother stopped the kissing as well."Well John, would you like to walk back to my room?" She asked."Yes Amy, I guess this means the. And as usual, she tried to encourage me to tongue her after and, as usual, I continued to decline. I do have to admit that where this was a fucked-up situation, the sex was incredible.On the following Wednesday, she didn’t announce her need to work late. I asked her about it and she said that there was no need to work this week, but that the project work would continue the following week. I have to admit that I was disappointed, but then it hit me: She was on her period those few days, so. Rob could see they were not offended so he carried on, the pleasure outweighing any embarrassment he may have had. The girl nudged her partner forward and they both knelt down by the side of Rob. She took Rob's cock in her hand and carried on rubbing it while her partner began fingering him. A spasm of pre-cum oozed from Rob's cock and the girl gave a hiss of delight. Now the girl’s partner was between Rob's legs with his hard cock throbbing against his anus. The guy looked at his girlfriend. Just then the electricity bit into my wired testicles making me groan out loud and tense even further. Finally, Miss Tosha dialed up the intensity of the final circuit and my entire urethra exploded in searing electric pain. “AHHHHHH, AHHHHHHHHHH, AHHHHHHHH GODDDDDD, FUCKKKK, FUCCCKKKK...AHHHHHHHHH FUCK, STOP, STOP IM SORRY SO SORRY.....AHHHHHHHH.” I screamed, saliva rolling down my chin. I was violently shaking as the circuits varied automatically in intensity by themselves and my bladder.
