dayfuck

The act of fucking someones partner during the day while the other is at work.

The fear of getting caught made the dayfuck I had on Tuesday the best fuck of my life!

After dayfucking my friends wife yesterday, she gave me a sweater of his that he doesn't wear....I love it!

Melanie dayfucked her friend Rachels husband to get back at her for openly flirting with her boyfriend.
