She was rubbing the huge cock in her left hand as she dealt this blow to Tom as he realised that she didn’t want him to play with her, she wanted hi... to undress her for Marcus. Tom slowly unbuttoned the blouse and forced himself not to feel her creamy breasts, the globes of which were sitting proud of her lacy, black plunge bra. He slipped the garment off her shoulders and down her arms and tossed it onto a chair. “That’s getting better,” said Marcus as he lifted a large black hand and gently. Wanting to feel the sting of your crop against my ass over and over. With each stroke of the crop my ass burns and my desire grows. When my desire is nearly overwhelming me you press against my ass rubbing your cock over my pussy and ask, ?My aren?t we a hot little slut. You are my slut aren?t you?? Moaning I press back against your cock and say, ?Yes Ma?am I?m your slut.? Reaching between my legs you spread my pussy lips, sliding your finger over my clit sending shock waves of pleasure. John was a doctor treating a disease commonly called by the name "cum addiction disease". The disease made life difficult for those with it, as their body became desperate for a protein found in abundance in human male semen.As the disease progressed, the women afflicted with it would become more and more desperate for it, need more and more to provide what they needed, and would experience an escalating state of arousal during times without treatment, which presented as nymphomania or sex. I placed my hands under her butt to help her out by lifting her up on her up strock and then letting her drop on the down strock. It wasn't long till she had another orgasum and went to jerking around on top of me while I kept pushing up into her and back down gently till she rode her orgasum out.When she had calmed down from her orgasum she turned around to face me still staying on top of me then she leaned over pressing her tits into my chest and went to kissing me like a lover does and I.
