A dirty Delena is when you come home after work and have your partner eat you out from behind by dragging their tongue from your vagina to your asshole
When you’re cheating on your girlfriend with a side hoe and are caught. But instead of getting angry, your main jumps in and steals your side because she can eat pussy better than you.
My main piece pulled a dirty deana. Now I’m sitting here alone wishing I had at least taken notes when my main stole my side piece with her superior pussy licking skills.
