I'm thinking of having relations with a grandmother for cash
If you think it's okay then go for it. Will she mind?
She's eager to make love and I like the idea of easy money.
Your endeavors are quite unusual but not unheard of. I say go for it but be careful as well.
Nah, I'm going to get all that easy cash.
While there are better ways to earn money if the grand mother is rich and she knows what she is getting into then I say go for it. Maybe it will turn into a fabulous friendship later.
