Mother in Law
I shouldn't do this, not for my son-in-law, but I feel so naughty watching you stroke your little clitty when you're not allowed to cum, especially when my daughter is out fucking a black stud. Well, here goes. Look, James, do you like my panties? Hmmm? All that's between you and my pussy is a thin coat of nylon and lace.
That makes you want to stroke yourself again, doesn't it? Well, go ahead, sweetie, stroke youself fifty times, thinking about how much you'd like to taste your mother-in-law's pussy. Oh, you're stroking soooo fast....be careful, you know what my daughter said, no cumming.
You're groaning and straining...that's it...right to the edge, honey, till you can't stand it anymore, till you're ready to explode...to fifty, then STOP!
