Next week Emma tells you she needs to be punished again

You come home late from work one day the next week and see that Emma is drying herself off after taking a shower.

"Oh, John, I'm so glad you're home."

"Me too. I had a super stressful day at work, my boss..." Emma lets her towel drop to the ground, stopping your story in mid-sentence. Your cock quickly jumps to attention as you think your girlfriend is horny and needs a cock inside her pronto.

"John, I've been a very, very bad girl," Emma tells you with a playful pout. "I need to be punished." She twists her hips to have her butt face you and then shakes her butt a little.

You smile at your cute girl, excited to play with her. You sit down on the bed and tell Emma to bend over your knees.

You look down at Emma's flawless ass and give her a very gentle slap.

"What has my naughty girl been up to?" you say, still thinking you're role-playing, and you slap her bum again. Your cock is poking into Emma's ribs as it strains against your pants.

"It was Jacob," Emma says. "I let him ... I let him have my ass."

A knot tightens in your stomach. Had Jacob really fucked your girlfriend's ass - something she has never begun to consider letting you do? She's been very, very clear that her butthole was off limits.

She must be playing, you tell yourself. But you can't help but ask, "When?"

"20 minutes ago," she tells you as you slap her ass - a bit harder now. Still you don't truly believe it, but you take your hand and slightly part Emma's cheeks. You know that there is no denying it - you're looking at an asshole that has recently been fucked. Emma's butthole isn't gaping, of course, but it was loosened up, for sure. There's no doubt that Emma has just been penetrated by a large object - and, you admit to yourself - why would it not be Jacob.

When you realize that Emma has just handed out her ass - her anal virginity to another guy you spank her ass harder. She let Jacob fuck her ass, you think, is horror and shame. You remember what it looked like to see Isabella's asshole stretched around his fat cock and you know that it must have looked the same when he took Emma.

Emma yells out in pain as you strike her even harder. Her ass is red and raw, but instead of asking you to stop she forces her hand between your legs and her body until she gets her fingers on her pussy.

Emma rubs herself as you slap her ass with all of your might. She flinches with pain and squirms in pleasure - both lead to her rubbing back and forth on your cock - which is still confined to your pants.

The more you see Emma moan in pleasure the harder you push yourself to get her to groan in pain, but you lose the battle and soon, with her bright red ass sticking up in the air, Emma cums loudly.

Her orgasmic writhing unfortunately also had the result of causing you to cum in your pants.

When Emma gets up off of you your pants are stained with both your and Emma's cum.

"I'm sorry again, John. I think I learned my lesson this time." Unfortunately you don't believe Emma for a second.
