I was working on a report in my study when I noticed the light come on in the house opposite. A group of girls, studying at the local uni lived there ... I'd spoken to them a few times and as I was a friend of their landlord's I would sometimes pop in if there were any odd jobs that needed doing. I saw one of the girls, Carrie-Anne, go into her bedroom. She was giggling, then turned round and started sexily taking off her blouse. A guy (her boyfriend?), already half undressed, came into sight. My black curls danced around my face. My ruby lips swallowed about his dick. I slid down him and then back up, leaving maroon smears behind.I shuddered, marking my son's cock with my lipstick. I danced my tongue around his crown. He gasped and shuddered. His face contorted in delight. His hands flexed like he didn't know what to do with them.“Shit, Mom!” he gasped.I slid my lips off his cock and stared up at him. I rubbed his cock into my cheek and cooed, “You like that?”“Yes!” His eyes were. " Well then, I guess I'd better get to testing it tomorrow," I said.Then I had another thought."Say Merlin, the boys are bound to notice I'm not using the regular stuff. What should I tell them if they ask?" Well, if you were in the marketing department of my old employer, you'd be saying it was a new, improved version of the original," he laughed."So what part is the improved?" I asked, laughing along with him."It doesn't smell funny," he said, laughing even harder.I couldn't help it. I was. Fuck! She knew every man in the room had his eyes on her fat asscheeks as she tried to walk calmly to the telephone. She knew that her “catch” black-and-gold dress was clinging to every contour of her asscheeks, causing every piece of dickmeat in the room to be rock-hard. Ooooooo, fuck, this was so nasty and no one had even mentioned sex. She dropped coins in the phone, asked to reverse the charges, and tried to ignore the pussyjuice making a tiny puddle on the band of her panties, thoroughly.
