Gives you blue balls and spanks you

Your cock throbs in her little hand. Even without her strokes, the sight of her wet tits sends you to the edge. They’re so fucking big. So slick. So suckable. You take a risk.

“Get on your knees. Let me blow on your tits.”

She grins. She rubs her thumb on your pee-hole. “No. That sounds like a reward. You need a punishment for snooping on your baby brother’s new wife.”

Her hand slips down your slick cock. She cups balls and squeezes until it hurts. You groan. They’re too full with cum. You’re at her mercy. Your sister-in-law and her big hanging milkers own you.

She spins you and pushes you against the wall like you’re under arrest. She rears back and smacks your bare wet ass. It splashes the wall with water. Her hand stings your skin. Her wedding bands scrape against your cheeks.

She spanks you over and over in the shower: your pants around your ankles filling with water and your hard cock pressed into the bathroom tiles. You’re humiliated, but so turned on. You could come right there.

But then she stops.

“Get out. I need to clean myself of your filth.”

You step out of the shower and soaking wet clothes. You’re making a mess. You strip the off. You take the one towel off the rack and use it to dry yourself.

The shower turns off. Your sister-in-law hand reaches out to the rack and finds the towel missing. Her head peeks out from behind the curtain and sees you with the towel.

“Give me that towel or that punishment in the shower is going to look like play. It’s going to hurt you. Now give me that towel.”
