of coursse u should let her and be happy but since she is the one to ask, set rules. the sex must be with u present, never alone. u join in if u want. u pick the men
Sexy 4sure, whether you agree or not, she is or will be eXploring her Desires, the best you can do is say Yes so as 2b included. i bet shes found and doing a real cocksman and he, she or both wants to make you watch, be ready to lick her swollen messy pussy, even if you think you wont, when she says U must prove U still love me by eating his cum from her b4 you can have sloppy seconds and reclain her,., Yes U will.
