Mom Wants You Back

I'm talking to my friend about how different life is now that our sons have gone off to college. I'm feeling sad that you don't come and visit me enough and am jealous to find out that my friend and her son have stayed very close. She lets me in on the secret - she's been having sex with her son and it's kept him coming back for more and more! I'm not sure it's a good idea but she says all the moms are doing it, it's just kept hush hush. You're coming round to visit me this weekend, so I decide to give you a visit you won't forget...
