Summary
     A second part to F*ck Off in which Shinsou actually gets consent this
     time and Aizawa makes good on his promise/threat and Shinsou loves
     it.
Shinsou couldn't stop thinking about what Aizawa said. He'd been avoiding him
for the better part of the week since it happened, but he has to confront it
sooner or later. 

Aizawa hadn't seemed mad or fearful in the slightest, and that was a little
frightening to Shinsou. He could deal with mad, he got reprimanded all the time
when he was still learning to control his quirk, and he still dealt with fear
on a daily basis. Needless to say, he'd never actually been sexual with another
person until now, and never romantically involved with anyone. He was nervous
about how exactly this conversation was going to go- he wasn't even sure how
he wanted it to go.

Still, he couldn't put this off any longer- he needed this training if he was
ever going to get into the hero course- so he stood outside of classroom 1-A as
everyone was packing up for the day to wait for Aizawa. 

"Let's talk elsewhere. Do you have anywhere to be tonight?" Aizawa got straight
to the point upon walking out and seeing Shinsou. 

"Ok, and no." Shinsou replied shortly, following Aizawa as he got ready to
leave. He grabbed his own things when it became obvious Aizawa meant off
campus; nothing else was said between them until they were outside.

"Where are we going?" Shinsou dared to ask as they walked, staying slightly
behind Aizawa. 

"My place. I don't live far. It's more private, but if you aren't comfortable
with that we can go elsewhere." Aizawa answered without hesitation. 

"No that's fine." Shinsou replied quickly. He could understand why Aizawa
wanted more privacy considering nature of what they needed to talk about. 

As Shinsou walked into Aizawa's apartment he couldn't help but look around
curiously. It didn't have much to it though- no personal touches. He briefly
wondered if it had come furnished already considering he doubted Aizawa would
bother with a couch and coffee table otherwise. 

Aizawa made tea and they sat on the couch to talk. 

"Nedzu already informed me about everything that happened, but I didn't say
anything about our session." Aizawa started, "I think there's value in training
your quirk that way as well, and I'll admit to not having been in some great
situations myself. It's a real situation that people like to pretend won't
happen. That being said, I think you know that what you did was wrong."

Shinsou nodded, looking down at his tea and swallowing thickly. Of course he
knew that, but he hadn't been thinking properly then. 

"I think you also understand we can't be caught doing anything sexual as a
teacher and student." Aizawa continued.

Shinsou gripped his cup tighter and replied quietly, "I'll take the blame for
it. You can't be held responsible for anything I make you do." 

"You won't have to if we don't get caught and I can make sure we don't. You
have my consent now so if you want to keep training your quirk this way we can.
I can tell you learned a lot from our last session."

Shinsou blinked up at Aizawa, who was looking at him with a smirk. He what?

"However, like I said before I'm not going to be left out again."

Shinsou took a sip of his tea, considering this. Aizawa allowed him time to
think. He trusted Aizawa and he couldn't find any reason not to take the offer.
He really did learn a lot.

"Only if I say you won't though right?" Shinsou finally commented slowly, "I
could just leave you, if my control doesn't break." He wasn't planning to, but
if he didn't lose control again he could.

Aizawa gave a small laugh, "Go ahead and try," He challenged.

"Right now?" Shinsou asked. Aizawa made to respond and Shinsou took control
with his quirk. 

He was excited that he had permission to do whatever he wanted, and truthfully
he was curious to see if Aizawa would actually go through with his promise/
threat. 

"Walk to the bedroom," Shinsou followed as Aizawa did as he was told. Part of
him wanted to make Aizawa suck him off again, but that was probably rather
ambitious if he wanted to maintain control this time.

"Take off your jumpsuit." 

"And your undershirt and socks." He continued as he watched appreciatively,
leaving Aizawa in only his underwear. Shinsou blushed at the thought of seeing
Aizawa completely naked; he didn't know if he was ready to take those off yet.

He was definitely ready to get off though, and started to undo his own pants as
he spoke, "Sit on the bed, in the middle."

He kicked them off along with his underwear and socks, deciding to leave his
shirt on, and climbed up onto the bed after Aizawa. He awkwardly and carefully
sat himself in his lap, back to Aizawa's chest because while Aizawa was sexy,
the blank expression was admittedly kinda creepy and this seemed easier
anyway. 

Shinsou checked his control before excitedly commanding, "Stroke my dick."

Aizawa reached a hand around Shinsou and took him in hand, starting to
gently rub up and down along the shaft. Shinsou was already embarrassingly hard
just from this situation and it felt great to have Aizawa touching him like
this. He leaned back against Aizawa and just let himself enjoy it for a few
minutes, until it became too much of a tease and he needed more.

"Faster, and harder," He let out a slight moan as Aizawa did as he was told. He
still had to make sure he didn't lose his grip on control though, and tried to
focus on Aizawa for a minute just to make sure. He could feel Aizawa was
starting to react a bit behind him and he looked up to see the blank stare
still on his face. Shinsou wondered if one day he could control someone's
subconscious reactions as well, but right now he wanted Aizawa to get hard
anyway. He wouldn't be able to find out what would happen when he left him
otherwise.

Shinsou ground back against Aizawa as he focused on being jerked off again,
getting close to finishing. He didn't know if he could keep his grip when he
came, in fact he suspected he probably wouldn't have held it this long if
Aizawa was giving him any amount of resistance. He didn't really care at this
point; He could work on that later after all. 

"M-more," Shinsou said breathing heavily, giving into the pleasure. He felt his
control slip just before he came, and Aizawa stroked him through it then took
his hand away, instead wrapping his arms around Shinsou possessively. 

"Do you want to ask me anything else?" Aizawa toyed with the hem of Shinsou's
shirt.

Shinsou collected himself and hummed thoughtfully, "No, I think I'm done."

Aizawa slipped one hand under and played with one of his nipples, making
Shinsou's breath hitch, "I'm not."

"Guess I didn't notice. Did you want help?" Shinsou grinned up at Aizawa,
daring him to answer. 

Aizawa manhandled him into laying on the bed, earning a squeak of surprise out
of Shinsou, and sat on his hips, stopping him from being able to get away. He
then used erasure, just in case, to answer, "I can take it from here."

He blinked and let his hair fall back down around his face as he reached over
into his nightstand drawer, pulling out a small bottle and and condom.
Shinsou's pulse started to pick up speed both out of nervousness and want.

Shinsou looked away with a blush as Aizawa got up and stripped off his
underwear. He felt his shirt being pulled up and raised his arms to let Aizawa
take it off. 

"So did you just get yourself off at school last time?" Shinsou tried not to
let his voice give away anything. Aizawa just gave an affirmative hum and slid
backwards a little so he was between Shinsou's legs instead of on top of him.
Shinsou heard the click of the bottle cap opening and glanced over to see
Aizawa pouring a generous amount onto his fingers. He then couldn't help but
also see how Aizawa was partially erect and turned more red. 

"What if I had decided to come talk to you right away?" Shinsou hardly even
knew what he was trying to achieve by talking at this point- Aizawa wasn't
going to let himself be brainwashed right now. He guessed he just didn't know
what else he should be doing and talking filled the silence. 
"Would I have walked in-" Shinsou cut off with a gasp as two fingers pressed
into him. He was more aware of them this time than the last time Aizawa did
this, and he could feel them wiggling and stretching instead of just going
straight for his prostrate. 

Shinsou swallowed and tried to ignore them for now as he started again, "W-
would I have seen you jerking off? Did you want to fuck me then too?"

Aizawa's response was to insert a third finger and Shinsou could really start
to feel the stretching now. It wasn't painful exactly- just uncomfortable.
Still he wasn't about to back out now and ask Aizawa to stop.

He forced a smirk and looked up at Aizawa again as he teased, "Impatient
already? Or are you trying to shut me up? Could've just used my mouth instead-"

This time Aizawa leaned over him, not stopping what he was doing and roughly
kissed Shinsou. Shinsou was left trying to catch his breath when Aizawa finally
pulled back, also pulling out his fingers. He grabbed the condom and rolled it
on, not hesitating to press against Shinsou as soon as he was done. 

He kissed Shinsou more gently this time as he pressed inside slowly. Shinsou's
hands found their way to his back and gripped tightly at the slight pain and
new feeling. 

"Fuck," Aizawa breathed out when he was all the way in, trying to wait until
Shinsou was at least somewhat adjusted. 

"Wasn't that the plan?" Shinsou responded without thinking. Suddenly Aizawa was
pulling out and slamming back in. Shinsou cried out and dug his nails further
into Aizawa's back. Aizawa started a rough pace that had Shinsou pressing back
into the bed and unable to hold back any noises. It hurt at first, nothing
unbearable though, but as he got used to the feeling and the pain dulled it got
better, and he moaned as Aizawa erratically hit his prostrate which felt
incredible. 

Aizawa stopped for a moment to flip him over so he was face down on the bed,
sitting up to grab his hips and fuck him again. Shinsou gripped the sheets and
moaned as Aizawa had a better angle to hit that spot more often now and even
harder. The pain was completely gone and Shinsou didn't want him to stop. 

Aizawa reached under Shinsou to grab his dick and Shinsou came almost
immediately. Aizawa fucked him through it and in only a few more
moments finished as well, burying deep and spilling into the condom. Shinsou
collapsed onto the bed panting as Aizawa pulled out of him and let go of his
hips. 

Aizawa disposed of the condom and rejoined Shinsou, picking him up and holding
him as he pulled the dirty covers back. Shinsou wrapped his arms around him and
fell asleep before he could even lay him back down. Aizawa felt a little guilty
for letting himself be edged on and going so hard, but Shinsou was a tough kid.
He laid Shinsou down gently and climbed in himself, pulling Shinsou close to
hold him. He would deal with it in the morning.
