Today's a BIG day for your girl, she's meeting with her boss for lunch & needs your help picking out the right outfit. After going through some options, she settles upon the shortest, tightest dress she has. You can't help yourself, you know it sounds a little.. odd, maybe even wrong but you're actually turned on right now. You half-way jokingly suggest she suck his dick while she's at it, & at first she thinks maybe its jealousy but she realizes quickly that you're actually serious.
And so, with plans in motion to her and her boss after their lunch meeting, you're about to have your little cuckhold fantasies realized.
