Mistress Brownleft him. Fear struck him. ?What?sgoing to happen?? He tried to think. His throat was sore and irritated. Heshouldn?t have looked at th... lesbians. Undoubtedly he will get punished forhaving a hardon. The mistress returned. He saw some kind of pump instrument witha catheter attached to it. ?Oh no!? Hemuttered. ?Shut up!It?s time again for your bladder expansion training.? She said while checkingthe water reservoir of the machine. ?I don?twant to do this? K protested. ?Fuck you!I?m. As my orgasm subsides, he pulls out of me and I realize that he hasn’t come himself. I feel his dick slide upwards towards my little rosebud. I shudder at the thought of his monster cock in my ass, but at the same time I relish the thought. He removes his hands from my blouse and uses them to guide my hips as he slowly pushes his monster past the tight ring of muscle around my anus. I loosen up for him as much as I can, but it still hurts a bit as he stretches me open. He pauses for a moment. "I'm sorry Mom, I shouldn't have said that."She looked out the window. "Sweetheart, if you could understand how hard it is sometimes..."I put a hand on her back. "I'm sorry, I didn't know. People just aren't used to it, that's all." You'd think after twenty bloody years they would be!" Well, maybe you could explain..."She cut me off: "The only explanation anyone needs is that I wasn't born here but I've done my best to fit in. That's all anyone needs to know."I dropped it -- I knew her early. "Go on the table there, kneel on it and take your hands on your back," she commanded me and tied my ankles and wrist with my body on the table. She got out of the room and came in after some minutes with a very big dildo she was wearing in the front. The big dildo was installed on a slip she was wearing and it seemed that she had a cock as a man.She fucked me with the dildo hard over an hour and she seems to have a dildo inside in her vagina too, because she came often to orgasm. First it hurt.
