You come too soon

Just the implication that she’s going to flash you send you over the edge. You groan.

Your cock throbs in your pumping hand. Cum spurts out and lands into the water. You brace yourself on the counter. You stroke and come more and more.

Your sister-in-law watches fascinated. She removed her thumb from her strap, leaving her nightgown on.

Humiliated, you wipe your cock with toilet paper and flush your cum. You wash your hands. The smile doesn’t leave her face. Neither of you say anything.

You leave the bathroom so she can brush her teeth in peace.

You literally blew it.

You smack yourself in the head.

It’s only Wednesday. You have a few more days to see them titties. She was just about to flash you. She watched you jack off. It should be so easy to see them.
