Offer your ass to make it even

You bask in the afterglow for a bit, until Mary gets up and starts to look for her clothes. A thought occurs, but you're afraid of what might happen if you make the offer, and more afraid still that she might accept. She's leaving and might never return. **** times call for **** measures.

"Mary..." you squeak just loud enough to get her attention. She stops and makes eye contact. "I'm really sorry that I put it in the wrong hole. I swear to God I didn't do it on purpose."

You're not sure if she believes you, but she assures you that it's okay and puts her bra back on, lifting each beautiful breast into its cup to get the best effect.

There's a power imbalance in your relationship. You did something without asking –️ something traditionally considered humiliating –️ and you need to even the score. "You can... get even with me if you like." She again stops what she's doing, trying to figure out what you're saying. "I know where to find a harness and a dildo if you'd like to fuck my ass."

Your heart stops as the words leave your lips. That was probably a stupid thing to say. And that was definitely a stupid way to say it. Fuck. Did you just mess this up?
