Watching wife getting ready for a date with her bull or for a girls night out can be so powerful aphrodisiac for a cuckold or a stag. Especially if she is dressing something slutty and sexy.
She has never looked better than this night while she was preparing herself for meeting some other men.
Watching her in stockings in front of a mirror putting on a lipstick knowing the fact that all of that lipstick is going to end up on his cock and balls. She is paying attention of every detail of her make-up and hair. What for? For some bull which is going to ruin all and send her back to you.
