These sound like interesting ideas. I personally like the skinny slob boy and handicapped wigger cripple ones. There is something about having a the mom doubly betray her son - not only by getting with the asshole who bullies him, but also if that asshole isn't even good looking or attractive. Like if the skinny slob is actually really gross, but the mom loves it anyway and still gives up her ass to him. There are some good stories like that on Literotica - one I can think of where a guy's wife gets stolen by this gross midget but she actually loves it because he's got a huge dick. Another idea would be to have the mom suck the cripple's dick while he's in a wheelchair. Anyway, would be interested to read what you come up with.

Any way I can track down the original YBOJ series? The stuff I loved was when Monica got pregnant and Chad and his buddies were fucking her, swollen belly and all.
