Your MIL notices that you're always staring at her ass. "How about we take this a step further?"(while licking My lips) I see how excited you are and laugh, "oh bb boy you're not fucking me, you're going right in here" (patting your belly).
Watch as I tease you with My ass, swallow you whole and tease you. "Since you love My big ass so much, now you can be a part of it."
