I’m a pretty busy girl and usually don’t have a lot of time to chase guys or date a lot. I’m a senior in highschool and just turned 18 about a month ago, and I plan on going to med school to become a dermatologist. I was taking a very difficult EMT certification class at a medschool program to help boost my student resume’ before leaving for college. Just for some background info, I’m about 5’4 with bright green eyes and dark brown, super curly hair. I’m Latina, although I couldn’t speak an ounce of Spanish if my life depended on it. Today was our last day of studying before our final practical test, so we were all stressed as fuck and trying to make absolute sure we knew how to do everything. Our instructor assigned us into groups of two, sending us to separate rooms with random skills that we may be tested on for the final. The class was very stressful, and a lot of people were forced to drop out, but those of us that were left had all become really close friends. I guess we all sort of bonded through the trauma of being high school young adults in a med school.
I looked down the list hoping I got paired with my best friend Alaina, but when my eyes settled on my name I was greeted by Matt written in next to it. This still made me smile, as I liked Matt a lot. He was pretty tall, about 5’10, white with the deepest blue eyes I had ever seen. He had short, well styled dark brown hair, with freckles across the left side of his face like someone lightly splattered paint on him. He was one of the funniest guys I had ever met, always breaking the tension everyone felt when we were all up in over our heads with the class. He had this warm way of smiling at you, making you feel like he was enjoying your company and it made it impossible not to like him. Okay, you can probably tell by now that I may have just a tiny crush on him. I couldn’t help it. He was even an avid gym goer and his body just made me wish I was curling up next him under a blanket.
I tried to never let those thoughts wander too far though because I was pretty sure he liked another girl in our class named Alexia and I didn’t want to impose. Either way I couldn’t help but feel a little excitement inside me when I saw I would get to practice on him. We paired up and walked a couple halls over to our assigned room and entered, closing the door behind us. The rooms are made to look like one in a hospital, with a single person bed opposite to the door, the wall flanked by a counter and sink full of medical supplies. There was also an IV pole in the corner. On the floor of our room was all the equipment needed to properly spine board someone.
“Oh fuck ya Spine boarding is like the only thing I had left to practice”. Matthew said happily.
“Ya I wouldn’t mind touching up on my skills either. Want me to do you first or you do me?” I asked.
He tilted his head to the side for only a moment before answering.
“I guess you can spine board me first and then that way If I fuck up after I can just start from the beginning without taking up any of your practice time”.
With that he promptly laid down next to the board waiting for me to start. Now when you spine board somebody, you’re technically supposed to have around 3 people, one to hold c-spine, and another to help you log roll the patient onto the board. We didn’t have that many volunteers that day, so we just said the steps out loud and pretended to do them. When I looked over at him just lying there, I couldn’t help but getting turned on. I had been so busy studying the past two weeks that I hadn’t masturbated even once, so my small 18 year old teenage body was so orgasm deprived that it hurt. There were boxes of blue gloves mounted on to the wall next to the door, and for some reason without thinking I just quietly flicked the lock on the door before turning around before turning around to put them on. I started listing off the steps out loud while standing to Matthew’s side as I rolled him onto the board. After padding him down with towels to keep him still I grabbed the fabric straps used to tie and stabilize the patient. I was listing off the steps, but as I looked at him I could feel myself get hornier and hornier as I went on. As if my body had a mind of its own I just swung one of my legs over him as I was placing one of the straps so that I was now straddling him with my thick thighs.
“Oh uhhhh I think it’s an automatic fail if you go over the patient” Matthew said.
“Oh I know I’m just having a lot of trouble getting this one in. I promise I’ll be able to do it tomorrow for the test though”.
Sitting on him in this position made me feel so uncontrollably hot, and I could feel my pussy become wet with excitement as I went on. I finished the chest strap, and rotated 180 degrees so that I could do his waist strap. I laced it through the board when I suddenly realized something. I could see that his dick was getting hard through his pants. Like, Really hard. Before I even realized what I was doing, my hand was sliding under his belt and pants and I started gently feeling his dick. I heard him let out a really quiet moan as I felt it, and it was rock solid. I could feel the tip of his dick being slightly wet and sticky, practically begging for me to ride it. I flipped myself around again and stared into his eyes. Without thinking, I leaned over him until we started making out. Suddenly I could feel both his hands on the side on my head pushing our mouths closer so I couldn’t escape. We sat there in that room making out, getting sloppier and sloppier as we became more and more horny as time passed. Half way through I slipped my hand into my pants and began gently rubbing my pussy as we made out, causing me to moan even more slightly in between breaths. When I couldn’t take it anymore I leaned back and asked him:
“Can I ride your dick?”. I said it almost out of breath as I realized how turned on I was by what we were doing.
“Oh my god I want you to so bad”. He said almost begging me.
While still straddling his waist, I managed to slip off my jeans and panties so that I was on top of him naked from the waist down. I peeled my shirt and bra off to reveal my smooth, decently sized boobs as they bounced a little from coming undone. I managed with some difficulty to rip off his shirt from beneath the straps, refusing to undo them as having him strapped down only made me more hot and flushed. I managed to get his pants undone and peeled his tight boxers away as his massive erection as it flinged out from underneath. I put his cock in my mouth for a bit, feeling it up with my tongue as he began to curse under his breath. I moved my hand up and down it to make sure it was nice and wet, before grabbing it so it was in line with my pussy.
I gently lowered myself down on his dick, gasping as he slid himself all the way into me. I was pretty tight, but he felt enormous all the way inside me like that. I practically shuttered as I began rotating my hips back and forth, feeling the different angles of him being deep inside me. He moved his hands up to grab my boobs as I was riding him, breathing heavily and moaning as I fucked his dick. I slipped a hand down to my clit and started rubbing it, my body erupting in endorphins as I sat there whimpering and moaning. I leaned over so I could kiss him, his lips gently moving from mine to my neck as I moaned harder. He cupped one of his hands over my mouth as if to keep me quiet, and I realized I was about to cum.
I tried muffling the words through his hand when suddenly it happened. I almost screamed out loud when I felt myself cumming on his dick, completely overwhelmed by the feeling shooting through my body. His hand over my mouth couldn’t even fully muffle it as my body shook and sputtered. I Clenched up, and could feel my pussy tighten around his dick. I started riding even harder while this happened on purpose, and suddenly Matthew moaned as I felt his boner pulse and throb inside my tight pussy. I could feel his dick shoot his cum inside me, and I slowed down my movements to a stop. I stayed there for a moment straddling him, his dick deep inside me as our breathing slowed. I slowly slid myself off and we sat next to each other, out of breath.
“Holy fuck” Matthew said.
“I know” I said smiling.
He suddenly saw his semen leaking out of me and got a worried expression on his face.
“It’s ok, I take birth control”. I said shrugging my shoulders.
I untied him and we sat there kissing for a bit before we finally got dressed again. We both went to separate bathrooms and cleaned up before heading back to get our stuff to leave class. I met up with everyone else, and watched Matthew come in soon after, his face still flushed red. I’ll never forget that experience, and am so much more thankful now that I took that class.
(P.S. We both passed the practical final!!!)
