Lisa got on her hands and knees on the rug before the fireplace, her big bare bum raised and her wobbly hooters swinging beneath her. I got behind her...and worked my prick into her twat before proceeding to fuck her hard. I held her broad hips as I pounded her furry snatch, delighting in the obscene cries of lust the horny bitch spluttered forth as I screwed her nice and deep. My mum sat on the sofa, frigging her twat and watching with glee, and soon she climaxed under the attentions of her busy. Already a little drunk, and dressed in a tiny white dress which seemed ready to unravel from her slightly plump teenage body at any moment.

I would like to point out that everything about right now is different than the last time, so of course it is not the same." "But I didn't make you cum," she objected. "Only because I wasn't ready to cum," I explained. "I wanted to outlast your first orgasm so we could see how well we do this." As I spoke I rolled us to the side. She allowed herself to roll with me until she was on her.
