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?”. ... 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. I can see your ass hole stretching and it's turning me on. I start to fuck you hard and fast and after about twenty five minutes I squeeze the balls and cum in your ass. I didn't know it would turn me on as mush as it has. I slide out of you and insert the butt plug into you and pump it up to stop it falling out. I pull your jeans up and boxers and you put all your stuff back into your bag. You remember that I have the balls inside of me and make me jump up and down knowing it will turn me on. It gave us a chance to chat, to recap events while they were still fresh, and certainly before she could start feeling even the least bit guilty about it. I knew for my part, I had to keep her from thinking like that, and thus keep it exciting, arousing even dangerous to some degree. I was beginning to understand my mother, better than she understood herself. We really, truly were far more alike than she obviously realized. But I knew without any doubt whatsoever, it was the "danger" part that. It was then that the experience of being anally fisted by Rebecca earlier worked against her, for the experience, although wonderful and erotic at the time, had made her sore inside, and the arrival of a largish cock in the same space was more than a little painful. She knew she could not beg for relief – speech was certainly out of the question as Jeanette pressed down on her – but she also could not concentrate on anything but the pounding weapon which was plunging in and out of her.
