"I said no funny business" Iida hissed as Hiroshi pulled him into the same shower stall witch a mischievous grin. "It's just a shower, I swear" the other winked and moved beneath the stream of hot water, his robe and Iida's boxers discarded by the corner of the showers along with their changes of clothes. "Just so that you have it in mind. Intercourse in the shower is rated the third most prominent cause of spine fracture related incidents. There's an 80% change we could slip and..." Iida blinked in confusion when Hiroshi didn't cut him off. "Aren't you gonna ask me to stop?" Hiro turned to look at him "Stop What? Your unnecessary display of useless knowledge? Nah... It's hot listening to you show off that big brain of yours" he smirked, running his hands throughout his hair, rinsing the shampoo away under the shower. "Keep going, what's the first cause?" He asked reaching for the conditioner behind Iida, courtesy of UA, High Alliance.

"Stairs"
"Of course, goddamn Stairs..."

Iida chuckled shaking his head "Be thankful I didn't pounce on you that day then" the other commented, squirting some of the creamy conditioner into his hand. "What day?" Iida finally gave in and stepped under the shower, sharing the stream almost equally. "Y'know, you and Midoriya were helping me with the bed, and we fell down the stairs... you on top of me" Hiroshi moved back a little to give more space for Iida to rinse his body while he finished cleaning his own. "You were in heat back then?" Iida blushed and looked at him quizzically over his shoulder. "It was the first day... or night to be precise. All I could think about were those stairs, those goddamn stairs" he remarked, suddenly hugging the taller from behind. "W-while you...?" Iida tensed up at the contact but leaned back comfortably, after all, Hiroshi was barely an inch shorter than him. "Oh don't flatter yourself, Kirishima and Midoriya helped a little too" Hiro laughed as Iida whipped around instantly. "What? Kirishima's a hottie and Midoriya's ripped as hell-" "So you are a perv!" Iida scoffed as quietly as he could, jabbing an accusing finger at Hiroshi's chest.

"Says the one who will, and I quote, force me to sexual relations if I don't comply..." Hiro snickered, as Iida sulked. "You still haven't let me explain my actions" Iida protested but the other waved him off. "I get it, to get me back into heat, I had to be forced. I couldn't go back on my own. And knowing that's what you were about to do would've taken the force out of it. I'm not dumb" Iida nodded, grabbing a soap bar from the corner of the shower stall. "Oof let me do that" Hiro took the slippery bar out of Iida's hands and rubbed it between his own eagerly, creating foam. "No, give it back" Iida reached to grab it but Hiro slipped under his arm with a yelp. "Careful Hot Stuff, don't wanna hurt that spine" He called teasingly just as Iida lost his balance for a second. He quickly caught himself and huffed "Come on... I really want to do it. Take it as one of many favors I owe you in return for helping me" he batted his eyes adorably and smiled once Iida nodded.

He placed his soapy hands, holding the bar in the right, on the other's shoulders. Letting the foam run down his back. He soaped down his arms and chest, lingering there for obvious reasons. Iida rolled his eyes "There's other areas that need to be cleaned you dog" he snarked immediately regretting it as Hiroshi ran his hands down his sides, to his back and down to his ass. He squished the firm muscle and smirked hotly "Better?" Iida blushed, nobody had ever touched him that way. "Ooh.. cat got your tongue?" Hiro pressed their bodies together in a wet embrace, cupping Iida's firm cheeks into his slightly clawed hands. Giving a light pinch. Iida yelped, quite uncharacteristically for someone his size. "Your claws are back" Iida winced reaching down and pulling Hiroshi's hands away from his backside. "That's your own fault for having low stamina" Hiro snatched his hand right back onto his butt and gave another squeeze drawing another strange yelp from the blue head. "Stop Hiro-" "Why? I can feel how you like it" he ran his hand up Iida's hip, drawing soothing circles. Iida closing his eyes tightly at the erotic feeling.
