MHA: Incubus Chapter 15 (Patreon)

Mina Ashido was a cutesy, girly, pink-skinned, and haired beauty who went to my class. After checking with Kirishima, whom we all thought had a crush on her, I was incredibly wrong, though. Kirishima was gay, and their relationship was one of friendship, not sexual attraction. It meant I was free to go after her in a romantic sense, as I didn’t want to step on any toes. If two people were dating, I wouldn’t try to break them up just so I could get at my female classmates… So far, no one was in an obvious relationship, but I wanted to make sure before I tried anything.  

She was also the next one open to being in a multi-person relationship with, and the next target for me to go after, once our classes began after the training break. She wanted to go on dates before anything happened. We went to an arcade, a walk in the park, and finally to see one of the newest movies coming out in the theatre that was about to be removed, so it didn’t have a large audience left. Now, she had lied a bit about what was really going to happen… Because I was blowing her back out even during our first date. 

She had a very strong kink; she wanted to have sex in public places. So we had doggystyle in the arcade’s bathroom, two employees at the door when we finished to kick us out, thankfully they weren’t filming and didn’t take a picture of our faces. Then sex in the park, where I brought a blanket and plowed her depths so loudly we had to run away before the crowd realized what we were doing, and finished in the bathroom as well.

The final time we had sex, she climbed on me at the back of the movie theatre and rode me until almost everyone had turned around to watch the show happening at the back of the theatre rather than the movie playing in front of them. We once again had to finish in the bathroom, as we had to leave before security showed up.

The thing was, her pussy was like a suction cup. I was worried about her vaginal juices being acidic, but she had mostly taken care of that problem through constant masturbation as she grew up. Still a virgin, but she had broken her hymen from playing with herself. Small at first, a finger or two in her entrance, then a small-sized dildo, finally, tearing her barrier fully with a large vibrator, she was an incredibly horny and sexually active(with herself) girl.

It meant that it didn’t hurt fucking her, but it was much louder than the other girls I had sex with. Skin on skin was a fairly common sound when we had sex, but the suction noise as her pussy gripped me and tried to keep me inside made a similar sucking noise to that of a wet suction cup finally being pulled off a wall. It was really a bad combination.

Her exhibitionist tendencies didn’t really pair well with her loud pussy, and as both our jobs were sensitive, if we did get caught, it could very well derail both of our hero careers before they even started. It was exciting, of course, but the excitement for me didn’t match the risk we were taking by having sex in public like this. It was also weird that we immediately started with her kink.

Normally, most girls want to start vanilla, then need to be convinced to do anything else. Very rarely did they introduce their kink to anyone they saw as a potential partner, for fear of them judging or even ruining the relationship with the information. But in all honesty, most guys are fine with almost all kinks. I’d even lick a girl's feet if she was into it, as long as she washed them first, even though I didn’t feel anything sexual towards feet at all.

With Mina… We were going to have the opposite problem, where I was going to have to convince her to take a few steps back… In all honesty, we couldn’t fuck nearly as long as I’d want to on account of us needing to leave immediately after she came to her first orgasm on account of her also being a screamer. Literally, everything worked against her kink, and it honestly seemed like she wanted to get caught.

I brought her to my mansion, sat her down, and had a real discussion about what she wanted out of this, because, while having sex in public was fun, it would end terribly with how often we were doing it. Three times in a week, and all three times we had close calls of getting caught. The moment someone snapped a pic or took a short video of me fucking her, our careers would be over, and the embarrassment of the situation might be enough to have my betrothal to Momo canceled.

The final reason I brought her here was that I was blue balled. None of those times I managed to cum, and because of that, I hadn’t experienced the strength boost that came from having sex with a new woman, only she did. So, after having the long talk where it came out that the neighbors used to do it out in the open on their patio while she spied on them. It might have been the first time she had ever seen anything like that happen. 

It awakened something in her; the kink drove her to the point she had difficulty climaxing normally if she wasn’t watching a video involving it or masturbating in public. She had a hyper sexualized fixation on exhibition and voyeurism, and didn’t think she could cum if we weren’t doing it in public… Alright, bet…

“How can it be this good? Your cock is like a cheat code! My legs are shaking from how good this is.” “Let me cum one more time, Pinky, then we can take a break.” I had more than proven my point that I could get her to the peak without us being in public… More than proven my point, I proved it over and over again for hours until she was exhausted, finally orgasming myself. The feeling of growing stronger wasn’t as intense; she was a weaker girl, so less affected by us fucking. She got a much bigger effect than I did, though.

If my other girlfriends gained about 10% extra physicality, she gained twenty, possibly even twenty-five percent. Now, that doesn’t seem like much, but when you reach your peak, ten percent is the difference in living with injuries or dying, it also started the snowball effect, twentyfive percent stronger meant she boosted me more, which let me boost my other women more, which meant when we had sex again she’d get another boost, and so on in a never ending cycle of getting stronger.

With one final thrust, I brought her to a seizing orgasm as she cried out, her voice worn ragged from screaming so much that it came out raspy. I felt a slight tingling, then a burning sensation as she orgasmed around me. Pulling out in pain, I couldn't help but notice that she had just burned a hole in bed, her body finally reacting to being fucked so much she lost control over her quirk.

She breathed out a sigh of relief before looking down and seeing what had happened. “Oh my gosh, I’m so sorry! Are you okay?” I just kept looking at the acid burn an ever-deepening hole in my bed as I responded. “Yeah… That hurt, but it wasn’t that bad… Actually, I think having sex with you made me more acid-resistant.” It was the only thing that made sense. I wiped the acid off my cock with a towel and watched it start to eat through the towel, while I only had small blisters forming that would heal by tomorrow…

So, it wasn’t just my physique and powers that got stronger, but I could grow in other ways than pure strength or contract magic. I thought that, if the acid resistance bonus also applied in my demonic form, I would be completely immune to acid… Most likely… I wasn’t going to go jumping into a pool of acid to prove I was.
