Today, (U/n) asked me to stay after school to help him with school work. 

Although his grades aren't the best, he really didn't need someone to help him. 

But whatever, it seems like he was really desperate. 

I just wonder why he couldn't do it during the self study period. 

Reaching my destination, our homeroom classroom, I walked in and closed the door behind me. 

"What subject do you need help with, (U/n)?" I asked as I took a seat next to the (Uke hair colour) haired male. 

"I need help with human autonomy, especially the parts around here," he said (in a weird tone, might I add) moving over to touch my crotch area, "and here~" he finished, placing a hand on his butt. 

Pulling out a binder labelled 'Biology', I flipped to a part near the end of the binder while I asked, "What do you need to know?" 

(U/n) moved a bit closer to me as he said "How these two parts merge together~" 

I sighed as he got even closer, "How would these two parts go together?" I asked, very confused as I flipped through the autonomy section, trying to find an answer. 

"Like this~" he purred, climbing onto me and grinding his butt on my groin, making me feel something I've never felt before. 

There was an electric feeling going through my body, making my body feel a bit weak and soft. 

"W-what? What is t-this feeling?" 

I saw a smirk appear on (U/n)'s face, as he whispered in my right ear, "This is a pleasured feeling, (Y/n)~ Mm~ It feels so good, right dear~" 

"Y-yes... Ah~" 

I covered my mouth and looked at the boy grinding on top of me with a puzzled expression. 

He chuckled and said, "That was a moan, (Y/n)~ A sound you make when you feel good~ You can moan all you want in here~" 

Hearing him say that, I slowly let my voice out, little by little, until I was practically screaming out my voice. 

(U/n) changed his position from hugging my neck and rubbing himself on me to wrapping his legs around my waist and moving one hand to his butt hole and the other to my penis. 

Not knowing what he was about to do, I panicked and stuttered "W-what are y-you doing?!" 

He chuckled as he shoved two fingers into his butt and grabbed my dick. 

"Trust me~ Ah~ This will make you feel even better~" 

He started to stroke me, from the bottom of the shaft all the way up, then back down, over and over again. 

Each stroke sent a wave of pleasure throughout my entire body, making me go soft at his touch. 

He eventually stopped and I made a noise of dissatisfaction as he laughed a bit. 

"Don't worry~ You'll feel even better in a moment~" 

(U/n) sat up and separated his legs and knelt on the sides of the chair, positioning his butt to dangle over my crotch. 

He started to slowly lower himself onto my erect cock, startling me in the process. 

"W-wait, what..." 

"This is called sex, (Y/n)~" he purred, moving his lips to mine and sucking on them, making me moan once again. 

"And this is a kiss~" (U/n) moaned as he sat all the way down, and I grunted at how tight his insides were. 

"W-what is s-sex?" 

Securing his arms around my neck, he start to move up and down, simulating what he was doing with his hand from earlier. 

"Ngh~ This is sex~ Ah~ Isn't it way better than my hand~?" 

I grunted and felt him squeeze my penis as if he were trying to keep it inside of him. 

The sounds we made were revibrating in the enclosed classroom as we did this pleasurable activity together. 

(U/n) was making a lot of what he called moans and some other good sounding noises. 

"(Y/n)~ How close are you~?" 

"W-what do y-you mean 'close'?" 

The smaller male on top of me stopped and I looked with confusion at him. 

He started moving again after he mumbled something that sounded like 'mood ruiner' and explained "You'll know soon enough~" 

We continued to do these activities for a while longer before I started to feel something hurt in my stomach, like a knot of some sort. 

"(U-u/n), my stomach hurts, a-a lot... I-is something w-wrong?" 

"No baby~ It j-just means y-your Ah~ gonna cum soon~" 

"W-what does that mean- AH~!" I felt something come out of my dick, as I screamed my lungs out. 

A chain reaction occurred as the small boy on top of me tightened his grip around my neck and shot a white fluid out of his own penis and all over himself. 

We both panted out of exhaustion as our bodies started to relax. 

"How did that feel?" 

"Amazing," I panted, still trying to recover from the intense exercise I just did. 

"But, it's really tiring..." 

(U/n) made a soft chuckle and took his jacket and gently covered me with it. 

"Just rest for a bit, take a nap," he said, pecking my cheeks before patting my head. 

"I'll stay here with you." 

I closed my eyes. 

"Okay... Will you do this with me again?" 

I opened my eyes when I didn't here a response. 

"(U/n)?" 

He started laughing before responding, "Of course, but you can't do this with anyone else. Got it?" 

"Got it." 

I answered, before drifting of to the world of dreams.

"Did you get it?" 

"You betcha (U/n)! I got a good angle of the entire process!" (Best friend name) said with blushing cheeks and a nosebleed.

"Let me see!" 

I pressed play on the camera as my new boyfriends erotic sound played back to me. 

"This is great masturbation material! Thanks a bunch (Best friend name)!" 

"No problem! Just give me a call when you want to do this again!" 

"M'Kay, see ya!" 

I watched as (best friend name) left and turned back to my sleeping (Y/n). 

I walked over and planted a kiss on his slightly drooling lips. 

"Sweet dreams, my prince~"
