Some names have been changed, like 'Mutsunokami' to 'Mutsu' and 'Tonbokiri' to 'Tonbo', since this is an AU.

Please, let me in. Sen knocked on the men's changing room door. Tonbo opened it.

"Ueda-dono?"

"I-I'm sorry." Sen kept her head down. "May I check in on Mutsu?"

"Of course, please follow me." He led her into the locker room.

Just ten minutes ago, Mutsu, during the rugby match, ran down the field with the ball in his arms and was tackled by an opponent. After the whistle was blown for a break, he couldn't stand.

"It's not that bad, y'know?" Mutsu lie on a mat, turned on his side, arms crossed. His white rugby uniform was tight around his form and stained with mud.

"Still, we have to take precautions." Yagen knelt by the mat. "Captain, he looks fine. He was temporarily stunned."

"I can play, right?" Mutsu sat up and clasped his hands together, begging. "I can't let the other team do this to me and let 'em think they beat me."

"Please, don't exert yourself, Mutsu-dono." Tonbo shook his head and Mutsu's mouth wavered. "We'll continue playing, but you must rest for the remainder of the game. I appreciate your efforts and enthusiasm."

And that was that. Tonbo's final words were what he parted with. Yagen followed him out, voicing agreement with the captain.

"Wait!" Mutsu bolted up and stepped towards Tonbo; he could convince him to rejoin the match, but paused when Sen stood in his path. Her worried brown eyes, staring straight at him, were enough to stop him, for now.

The door creaked shut behind Sen, leaving them alone in here.

"Are you alright?" she said. Sen put a hand on his arm. He didn't wince at her touch.

"Course I am." He raised his hands up. "Don't I look fine?"

What else could she say? Sen had to make him stay, convince him these restrictions were because everyone cared about him.

"Everyone's a big worrywart." Mutsu pouted and turned around, hands on hips. "I broke a couple bones when I was little, playin' around! Lyin' down, doin' nothin' is such a-"

"You trained so hard for this match!" Sen hugged him from behind. He always attended practice and worked out in his dorm. She saw him improve over the years, listened to him talk about the matches and rivals; she understood his disappointment, the frustration. "But please, don't push yourself like this."

Mutsu stiffened, not expecting her to reach out like this. Being fussed over was an annoyance; Sen should focus on other things. Though, knowing that someone cared for him gave him pause to reconsider his goals and choices. Right now, he had to slow down and address his partner.

"Fine, Sen-chan." He pried her arms off him. "But when I'm healed, I'm goin' back to the field."

He turned partially towards her. His bulge poked against his tight shorts, evidently growing. Sen stared down at it. When did that happen?

Mutsu's eyes darted away from her. For once, he blushed. "When you hugged me, I felt your boobs! I don't feel those on my back a lot."

When they napped together, sometimes she rolled over and spooned him, but usually, their positions were reversed.

He could stay here and wait for his erection to go flaccid, but that was a missed opportunity. This would be their first and last time in the locker room. When would they get another chance to have sex here?

"We...should take care of it." Sen looked away from him, wringing her hands together. They were going to do it. They'd be alone here for a while until the match ended.

"Oh." Understanding her, he smiled. Mutsu stepped close to her. His bulge pressed against her belly. She stayed where she was. That hardening cock grew with warmth. "Have you thought about fuckin' in here before?"

Sen gave the tiniest of nods. This was where all the rugby players stripped down, dressed, and showered. Of course, she imagined what it was be like to be in the middle of a group of undressed muscular men.

"Well," he couldn't help but chuckle. It echoed in the changing room. "I've thought about it too. There are some hot guys on the team, like the captain, right?"

Her face burned. Taking Tonbo as a lover would be a dream come true, but she couldn't answer Mutsu; it would only encourage him to continue his banter.

"I don't have condoms," Sen said.

There was a limited amount of things they could do without protection. What was quick and safe? A handjob? A blowjob? The prospect of her mouth on his cock was a good one. Her knee-length skirt brushed his legs. All she had to do was lift the garment up and he could rub his dick between her thighs.

"How about we do it there?" He pointed at the space between her legs.

Sen nodded. This act was one of the first things they tried as a couple.

"I got another idea!" Smiling, he led her to the adjacent shower room. The walls were lined with stalls and shower heads. "This is where we wash up. If you had to choose, would you be here by yourself or with the whole team?"

"T-the whole team." Wasn't her lust obvious?

"Alright, so imagine it." His form pressed Sen against the wall. Mutsu slipped his shorts and briefs low enough for his erection to pop out. He grinned as they watched him stroke himself. Precum leaked down the head of his cock. "Sometimes, when I'm in the stalls, I get hard seein' all the other guys gettin' naked and coverin' themselves in suds. I jacked off once and nobody noticed. I've thought about fuckin' some of them. Have you?"

Sen lifted her skirt up. She was supposed to be loyal, faithful. No matter how many times Mutsu teased her about hooking up with others, she was tempted to lie about her desire. She wrapped a hand around his slicked cock and guided it between her thighs. The shaft pulsed with heat right against her panties. She pressed her legs together as he started to thrust back and forth.

Their gasps and the slapping of their skin echoed in the the locker room. His cock, thrusting in and out between her thighs, glistened with fluids. His uniform, soaked in sweat, clung to the shape of his abs. His muscles bulged every time he flexed and rocked his hips against her. Mutsu gripped her waist; his arms tightened as he held her in place. Sen felt all his strength flow out of his body, his focus on fucking with each thrust; she couldn't help but shudder at the heat they made.

"Heh, when you shake like that, Sen-chan, I'm goin' to come faster." A knot was building in his cock; his climax was almost here.

"T-then, do it on my legs, Mu-chan."

He did as she said. Mutsu stepped back, stroked himself for a few moments, and came on her. His semen landed on her thighs and rolled down, leaving white streaks down her legs. Some of his seed mingled with mud. Mutsu shared that dirt with her when their legs were up against one another. His come soaked her socks. Some of it dripped onto the tiled floor.

Mutsu leaned forward and she embraced him, supporting him up as he caught his breath. He huffed right against her neck. He could perch there as long as he needed. She kissed the side of his head; his hair was sweaty from their activities.

"Hey, Sen-chan." Mutsu straightened up and snorted. "You need a towel."

"So do you, Mu-chan." They were both a mess.

"Shame we can't fuck in here again. You want to go in the stalls and shower together?" He kissed her forehead. They had done so much today, yet they were still unsatisfied. They last had shower sex a few weeks ago. Now, they knew exactly what they were going to do after they left the locker room.

"We can continue in your dorm." If they stayed here long enough, the rugby team might catch the two of them.
