The competitive rivalry between Bakugou and Midoriya continued well after they graduated UA. Working at the same hero agency, they passed their patrol time making bets and challenges.

They started out innocent. Who could catch the villain first, who could cause the least property damage during a mission, etc. The penalties started out harmless as well. Loser paid for meals, cleaned around the agency office, ran out to get coffee or groceries. While the bets remained normal, it was the wagers that grew more... daring.

One of the first lewd punishments had Deku wear Uraraka's bra and panties under his hero suit for a day (she only gave them up after learning who would be wearing them). Bakugou lost and had to perform at the next group karaoke night— in full drag.

"Who knew Kacchan could nail such a slutty walk in 6-inch heels?" yelled Kirishima as their group cat-called and whistled as Bakugou grudgingly continued with his punishment dance.

Bakugou swore that Deku's next penalty would be far worse than this humiliation. Midoriya only nodded as he watched Bakugou shake his latex-wrapped ass to the dance music. The skin-tight outfit accentuated Kacchan's tits, and Midoriya couldn't stop staring as the group drank and laughed the night away.

Bakugou lost their next challenge as well. This time, Midoriya demanded Kacchan put on the drag outfit for a private performance at his place. Bakugou groaned and swore to make him pay but relented to his punishment. He was no coward or a sore loser after all. He decided to wear a different outfit this time.

Not that he wanted Deku to enjoy it or anything. The orange and gray corset was just less restrictive, that's all. Midoriya's mouth dropped when Kacchan strutted out of Midoriya's bathroom in stilettos and skin-tight leather shorts. His massive chest overflowed from atop the cinched corset.

Midoriya was rock hard and sweating as Bakugou stared daggers at him while he sashayed around the room. Crossing his legs and using slow, deliberate movements, Midoriya discreetly massaged his throbbing erection to this display. Bakugou knew what Deku was doing, and it should've made him angry. And he was pissed off. Why wouldn't he be? The shorts were riding up his ass and the heels made his toes ache.

But fuck... The thought of that green-haired bastard rubbing himself off right in front of him made him want to cum all over his freckled face.

Bakugou wanted to see that face turn all shades of red, so he worked his ass harder to the music Deku's shitty little phone put out. He uncrossed his work partner's legs, staring at the damp spot at the top of the tent in Deku's pants.

"You dirty slut," was all Bakugou said before he slid onto Deku's lap, grinding his crotch against Deku's bulge.

"Nggh, Kacchan… W-what are you…" Before he could finish talking, Bakugou clapped a hand across his mouth.

"Shut the fuck up, I'm just fulfilling the penalty. You wanted a performance, so you're getting one. But remember, payback's gonna be a motherfucker."

Deku could only whine in reply, the wet fabric of his pants sliding along the black leather shorts provided just enough friction to stimulate his aching cock.

Bakugou knew Deku was getting close by the way Deku jutted his hips towards him, begging for more contact. And just as the song ended, Bakugou uncovered Deku's mouth, stopped pressing himself against him, and whispered, "uh oh, looks like the performance is over."

Standing up, he watched with intense pleasure as Deku desperately sought a way to cum. Staring at Bakugou with pleading eyes, he couldn't bring himself to ask Kacchan to keep going, but he couldn't wait for him to leave to finish either.

Resorting to his own hand, he thrust it into the waistband of his pants and furiously started to stroke his wet cock. He had been so close to finishing before Bakugou stopped dancing -no- dry humping against him. What a cruel thing to do! But Midoriya couldn't say that it surprised him. Kacchan was more than capable of being a spiteful bastard.

His sense of embarrassment was overwhelmed by his frantic need to cum. As Midoriya fucked into his tightened fist, he groaned as his hot load coated his fingers, creating an even darker wet spot on his clothes. Bakugou took in the sight, his own urge to fuck eating away at him.

"I'll see myself out since you got your hands full, you slutty nerd. See you at the office."

Deku was still in his cum haze and paid no attention to Kacchan walking to the bathroom on unsteady legs. He didn't even notice the grunts and moans coming from there as Bakugou peeled the shorts down and started to masturbate. He'd be damned if he'd let Deku know how turned on he was by what went on tonight. And just to show how little he cared, he came all over Deku's toilet seat, leaving a sticky reminder for him to discover later.

Satisfied and changed back into his street clothes, he left the bathroom to see Deku asleep where he'd left him, jizz-coated hand still in his pants.

"Yeah, payback's gonna be a real bitch, Deku, just you wait."
