If your beloved is cheating with her friend, you can be a co-cubod

Lick her to orgasm, and before she comes, cum inside her. It works

"Husband, don't rush, I'll cum first, then you can fuck me however you want."

Do what you want, honey, but I'm not getting off my dick until I come

If you want a discount, you have to fuck me to orgasm first. There's no other way
