Another long day being a hero. You were glad it was over and you kicked your shoes off as you entered the apartment that you shared with your boyfriend, Hanta.

“Babe?” you called out as you stepped up into the hallway and walked along.

You could faintly hear water running and followed the noise to the bathroom.

As you pushed the door open, you saw Sero in the shower, one of his hands lathered with soap and wrapped around the girth of his cock- sliding rapidly up and down his length.

That immediately got you turned on and your excitement grew as you watched him place a hand on the tiled shower wall and lean forward a bit- the hand around his cock staying still this time as his hips bucked back and forth against his curled palm.

“You started without me?” you asked loudly, scaring him so much that his hand on the wall slipped and he face planted into it, which made you laugh.

“Heart! You scared me,” he said in a relived voice, letting go of his cock and washing the soap off his rigid member.

“Hey now… don’t stop, I was enjoying the show,” you crooned with a smirk as you started to take your hero costume off, “stay there. I want to join you.”

Sero nodded and his eyes slid down your body as you revealed your naked form to him, his cock twitching when you removed your pants and straightened.

“You know… watching you stroke yourself like that had really got me going,” you said as you walked over and hopped into the shower with him.

“It has?” he asked, turning to face you as you put your body under the flow of water.

As you got warmed up, Sero kept one eye on your below the belt status, desperately wanting to touch you but holding off until you were ready.

Once you were well and truly soaked, you stepped back from the flow of water and slicked your hair back.

“Now,” you said to him with a smirk as you reached out and took a hold of his cock in hand. 

The soap had washed off by then so you reached for some more in your free hand and lubricated it up then applied it to his shaft, rubbing up and down then circling around his tip before sliding down to his balls and swiping them as well with your fingertips.

Sero was like putty in your hands and let you do your thing as he hunched over your softly held fist slightly.

“C-Can I touch you as well?” he asked with his mouth hanging open a little.

You nodded and he reached out and stroked you.

“You know I’m gonna wanna be inside you,” you purred as your wet lips brushed his earlobe, “when you touch me like that I can’t hold back.”

“I’ve been fantasizing about you taking me from behind,” Sero replied lowly, pre-cum leaking from his tip and blending in with the soapy suds.

“Well fantasize no more because it’s about to happen,” you said as you pulled back from him and turned him away from you, stepping in behind him and rubbing yourself on his ass.

You still had your hand around his cock and kept stroking him as your other hand slipped between his cheeks and massaged his rear opening.

“Bend over. Hands on the wall,” you commanded when you couldn’t quite get a good angle to penetrate him with your finger. 

He obeyed immediately and pressed his lower back down so that he presented to you, his need growing as you continued to pull and massage his cock.

“H-Heart, please,” he groaned, his eyes scrunching closed with desire as he waited with agonizing patience for you to enter him. 

Slowly you inserted one finger into his ass, pushing it in all the way before pulling it out and pushing two in.

The sudden change in pressure caused him to jump but you kept stroking his cock, keeping him excited as you prepared him for your own pleasure.

After a little more pushing and pulling of your fingers, you pulled them out and pressed yourself to his opening.

“Please, Heart, make me yours. Own me,” he begged, his arms starting to tremble as they held his body against the wall.

Slowly your hips moved forward until they touched his ass and he let out a low groan of delight as you became one.

The whole time that you pleased yourself, you made sure to stroke him. Stopping a few times to get more soap and use it on his cock so that he was well and truly stimulated.

“Hanta, can I reach my climax inside you?” you asked through ragged breaths, feeling like you wouldn’t last too much longer.

“Yes, please, Heart, please…” he rasped, water rushing down his shoulder and side of his face as you forced his body to lurch back and forth with your efforts, “I’m close… I’m so close…”

Panting wildly, his body shook and he let out a loud wail of delight as he let you stroke him to climax and no sooner had he finished you let go of his cock and grabbed his hips, rocking his body against yours a few more times before you too, followed suit.

Once complete in your quest for climax you pulled out of him and spun him around, your lips crashing into his as your kissed passionately under the water- the perfect completion to a big day.

“Let’s get take out tonight,” you said as you pulled back, “I’m starving and I can’t be assed to cook.”

“Neither can I… I’ve already cooked my sausage,” he said with a wide grin as he turned the shower off and stepped out.

“You’re an idiot,” you chuckled, stepping out after him and smacking his ass.

“Owwww,” he whined, holding the cheek you just smacked.

“Oh sorry…” you chuckled, “here let me kiss it better.”
