I got a weird invitation from Lisa at school today.

She told me that I should meet her after my close combat class ended so that we could 'shower together after I got all nice and sweaty'.

I obviously know where this was going of course, but she could have asked me for shower sex back at home instead of doing it in school. Then again… I don't think we have a shower at home do we? We only have baths.

I assumed that she probably wanted to have some risky sex where we might possibly be caught for the thrill of it.

Thus, when class was over, I headed directly for the specific shower room where Lisa was waiting for me. She had told me to meet her at one of the staff's bathrooms which was reserved for teachers so no other student would go there.

Sure enough, I found her standing outside alone with a bath towel hanging on her arm.

"Ah! Aster! You're here!"

"Hello Lisa, I see you're prepared."

"Ehehehe~ Mmm~ You smell so nice, Aster~ You're really making me addicted to this~"

I was about to point out that I was sweaty all over until I remembered that I had the [Roses] boon that ensured I would always smell nice.

"Shall we go in then?" I asked.

Lisa poked her fingers together, "Umm… Before that… Could I ask Aster for a favour?"

I tilted my head at her, "Umm… Sure? What do you need me to do?"

"Ehehehe~ Well… Aster still remembers that… Ummm… Aaron, right?"

Did she almost forget his name? Aren't you supposed to be 'dating' him right now?

I nodded anyway, "Yes, what about him?"

"Umm… I was thinking of doing a little roleplay where I was supposed to invite him to shower with me but Aster comes along and then forces yourself on me~"

"That's… Oddly specific? But I guess I can do that. So how should I act?"

"Ehehe~ I'll leave it to Aster to decide~ You just need to force yourself on me~ Even when I'm begging you to stop, just keep going, ok?"

"Err… Should we have a safe word?"

"Safe word? Eheheh~ I don't need something like that, Aster~ I will take everything that you give me without complaint~ Choke me, beat me, restrain me~ Anything you want!"

Mmm… While I might reject a suggestion like that if anyone else had been suggesting that to me, this is Lisa we were talking about here. I don't doubt that she would actually be able to take everything I might do to her.

"Alright, then should we go?"

"Ah! Could Aster come in after me? I'll start showering first to set the scene then Aster can come in after that~"

She seems to be really serious about putting on this show huh?

Since I didn't want to ruin her fun just for this, I nodded at her which prompted Lisa to walk into the bathroom itself to set the 'stage'.

I waited outside for a while until I heard the sound of running water coming from inside, which I took as my cue to enter.

Walking inside the shower room, I found Lisa easily enough by following the sound of the water and what sounds like Lisa humming to herself.

Nearby was a small bench where she had stripped off her clothes neatly to be placed in a pile, which subtly indicated that I should do the same.

I stripped myself and hung my own towel on the rack nearby before I headed towards the shower cubicle.

This story is posted elsewhere by the author. Help them out by reading the authentic version.

Before you ask, the shower does not work using a plumbing system but more from the usage of Mana Crystals installed in them to provide water.

I intentionally made a noise as I neared her, letting her know that I was here since she had her back towards me.

"Oh? Is that you, Aaron? Come on in~ I just started~"

Seems like our roleplay has already begun.

I opened the cubicle door that only hid the middle part of our bodies from view and stepped inside, closing it audibly behind me.

Hmm… I wonder how I should play this?

I need to play the role of someone who isn't Lisa's lover but as one of her students I suppose.

So now I've found my Lumenmancy/Alchemy teacher showering here alone and realised that she's dating one of my classmates.

Obviously if this was anyone else, I wouldn't care. But I guess to 'rape' her, I'll play the part of a jealous student who has a crush on Lisa and can't accept her dating someone else.

"Mmm~ Aaron, could you help wash my back? I'll do it for you later~" She asked, still with her back to me.

I guess I can start with that first.

I spread some soap on my hand and began washing her back, soaping her up while she did her front by herself.

At first, I did my part innocently until I slowly shifted my hands forward to start soaping up her tits.

"Aahhnn~ You're so impatient today As… Aaron~"

I chuckled inwardly at the fact that she almost called out my name.

I continued to massage her boobs, feeling my member harden as I got turned on by her.

Lisa's moans filled our cubicle as she enjoyed the sensation of my hands on her boobs, her voice increasing in volume whenever I pinched her nipples.

"Oh, Aaron~ I never knew your hands would feel so good on me~ If I had known, I would have invited you sooner~ Oh, right there~"

Spurred by her words, I moved myself closer to her until I was pressed up against her with my cock nestled in between her thighs.

She let out a gasp as she felt my cock slide past her pussy lips before emerging between her thighs, peeking out from below her own erection.

Her hands went down to fondle my cock, "Oh wow… I never knew you were packing such a wonderful cock Aaron… Oh… Oh the shape… The size… Mmm… It's like I was made for this cock… I know this would fill me up perfectly~"

My cock twitched from her praise and I decided to start the 'rape' part of the scenario right now.

I pulled back and spun her around, causing her to let out a squeak of surprise as I pushed her against the wall.

She gasped in 'surprise', "E… Eh?! Wait! You're… You're not Aaron! Who… Who are you? What… What are you doing?!"

Hmm… She's pretending not to know me, so I guess it's not the scenario of her other student coming on to her but just a stranger? I guess I can work with that.

I purposely lowered my voice into a baritone, "My, what are you talking about? Isn't it obvious? I'm here to fuck you."

She struggled weakly against me, "Stop this! Or you'll regret it!"

"Oh? Then I suppose it's fine if I were to tell everyone that you were here waiting for… What was his name? Aaron? I wonder what everyone would think if they knew the cold and infallible Lisa is here in the showers waiting for her student to come fuck her?"

"No… No, please… Anything but that…"

"Then if you want this to remain secret, you'll do what I say right now."

"Please… No… I… I promised myself to remain pure for him… I can't…"

"Oh what are you talking about? I'm not asking for a kiss, all I want is just to have my cock sucked."

"Is… Is that enough?"

"That depends on how well you do it, doesn't it? So why don't you convince me that all I need is just receiving a blowjob from you?"

"That… I… Please… I'll do it… But don't… Don't let anyone else know…"

She may sound pleading and desperate right now but her face was one of euphoric bliss so it really did not sound convincing at all. Like seriously, there's even a line of drool spilling past the side of her lips while she was making a really lewd face at me.

I grabbed her by the shoulders and pushed her down on her knees, my Infrid kneeling without putting much resistance.

She's also in her Mahun disguise right now so it makes it even more erotic as it feels like I'm doing this with someone else.

I then presented my cock to her and though I could see that she really wanted to start sucking me off right there and then. She was still trying to act like she was still hesitant about it as her hands would reach forward before retreating a few times.

Taking that as a sign from her to take charge, I grabbed her head and tilted her back before thrusting my cock into her mouth.

She gargled in pleasure as her eyes rolled to the back of her head.

Her hands grabbed onto my thighs not to push me away but to pull me closer to her, prompting me to start throat fucking her.

Lisa seemed to remember her role as the 'unwilling' participant and started hitting my leg half heartedly as though to stop me, but I did not pay her any mind and just continued to fuck her mouth like how she wanted.

The fact that her tongue kept licking the underside of my cock and how she kept sucking on me showed me that she was really enjoying this.

It didn't take long before I was dumping my load into her throat, my cum shooting past her mouth to deposit my seed directly into her stomach.

She gurgled as her body shook from what I recognised as an orgasm, my Infrid swallowing all my cum without complaint.

Only when I was done did I pull back, though a few spatters of my cum still stained her kissable lips.

She was in a daze for a moment before she started fake coughing, "Cough! Hack… Ugh… Deli… Disgusting… Is this enough? Can I go now?"

She looked up at me with a rather vulnerable look, which only made my cock twitch and harden in excitement.

Ah… Not good, I think my switch has been flipped.

"Not yet," I grinned as I stepped towards her.

Hey, she wanted this.
