“What?” she said a little startled.“I know how you can make me cum,” I said.“You want me to suck on it?” she said a little too quickly for... her liking.“No, well actually... that might work too... but I was thinking maybe I can slide it between your breasts?”“Well there's a thought. Suck on my son's hardon or let him slide his penis between my breasts.” I smiled a little guilty.“Alright, come on then,” she motioned me towards her as she rubbed some lotion between her breasts.I didn't just slide. She realised that Frank had been a lot younger than she expected, but even so, he was far too old for her. On the other hand, she rationalised, she did actually like him and really wanted to at least get that $5,000 he had offered. What's more, she told herself, it would be rather cool to lose one's virginity to a mature man, someone who would really know how to make love to her.She hadn't told the full truth when she said that she hadn't had any boyfriends. She had enjoyed kissing and cuddling. As the bump and grind continued, so did the dirty talk. "Fuck me baby. Fuck me with your hard cock. I want all of it in me. Then I want you to fill me with your cream". Mike, not at a loss for words, "Take it baby. Your pussy feels so good on my cock. I want you to cum all over it". This was going on for the next 20 minutes or so as the pace increased. Mike was now pounding Sarah's pussy and he was getting close to shooting his load. He had Sarah move her hand down between them to. "Shit! How the hell did my bastard brother learn to use that one? His balls are toast." Do I still need the chisel?" I asked."To deactivate the sigil, you moron. I'll tell you where and when."While she studied the sigil, I studied her. Six inches of very nice looking naked blonde female, if you liked your women extremely small, angry and with butterfly wings that is. She was bending over, peering at the rock, so I could get a good look at her bum. Apart from the size, her shape was late teens.
