that would have been the perfect time to clean her pussy.. right after you fucked it too to feel how good it is fucking her while she is full of cum...and enjoy the feel of his cum and yours in her
you should get it from her then and call him.. explain the situation and how you want her to be fucked by him. surpeise her when he shows up for dinner and drinks lots of drinks
did she give him her number or just him giving his to her. the perfect way to invite him over for dinner and drinks..strong ones or even ask him to join you and her at a bar/club where they can dance together
