The study partner

Marissa is at the top of her class, partly because she studies hard, but also because she has a very good study partner. He is very good at math and that is not exactly her strong side, but because they study together, she gets decent grades in math.


They study every Tuesday and Thursday, usually math or history (which I’m really good at). A few days ago, they started a new 3 week course. ‘Sex-Ed’, they called it. Sexual Education. The teacher told them, that since they are legally adults now, they have to learn about sex and that they will actually get graded in it. As soon as Marissa heard this, she paid extra attention. Grades are very important for her.

Everyone got an introductory brieflet that they were told to memorize. They never had such a short course, just 3 weeks to learn everything, so Marissa was intent on making sure she made good use of her time.

“Let’s just go through it page by page” Miroslav suggested.

“Sure, let me see, the first page has all the names of the body parts. Hmm, they really start at the beginning, almost explaining the concept of arms and legs.” Marissa laughed. “I knew that these are called breasts” she said and pointed to her breasts.

Miroslav smiled “Yes, but I’m sure it’ll become more difficult later on”.


Marissa and Miroslav had a routine of studying. They had been study partners for more than 5 years and they knew the best way to do math, is to solve math and work with it, not just to read about math.

That’s why it was natural for them to take a practical approach to learning.

“OK, let’s see, the second page is headlined Erogenous zones” Miroslav said. They both silently read the following paragraph.

An erogenous zone (from Greek eros "love" and English -genous "producing" from Greek, genes "born") is an area of the human body that has heightened sensitivity, the stimulation of which may generate a sexual response, such as the production of sexual fantasies, sexual arousal and orgasm.

“Example” Miroslav said “Mouth: The lips and tongue are sensitive and which can be stimulated during kissing and caressing.”

Marissa looked at Miroslav and Miroslav looked back at Marissa. It was slightly awkward. “Let’s see” Miroslav said and slowly leaned over and kissed Marissa on the mouth.


Both made a subtle and asexual “Aha” sound as if they had just heard an interesting fact, such as Did you know that there exists about 3000 species of spider. Aha.

They turned back to their little book and Miroslav read on.

“Example” Miroslav said, reading aloud from the next section “Intense nipple stimulation may result in a surge in the production of oxytocin and prolactin which could have a significant effect on his or her genitals”

“Significant, even?” Marissa commented.

Miroslav leaned over and kissed Marissas nipple and played a bit with it with his tongue.


“OK?” Miroslav asked afterwards.

Marissa nodded. “Yes, it works, I think I can feel the oxytocin or …”

“Prolactin” Miroslav said. “Oxytocin and Prolactin”.

“Yes, that one too” Marissa said. “Prolactin” she repeated, making sure she would remember this.

Miroslav nodded. “Only 3 more pages left. Let’s look at the next page”

Both gave out a mild gasp when they saw a picture of a penis and a vagina in the book. “Genitals” was the headline. “Genitals” Miroslav said, as if it was unclear what they were looking at.

“Female” Marissa read, the subtitle of the first section. They both read the following section about the vagina silently.

Parts of the vulva, especially the clitoris, are highly sensitive and are erogenous zones. While the vagina is not especially sensitive as a whole, its lower third (the area close to the entrance) has concentrations of the nerve endings that can provide pleasurable sensations during sexual activity when stimulated.

“Well” Miroslav said “The proof is in the  … pudding”. He paused before saying pudding, but decided there was probably not any freudian slip in that.

Marissa lifted her eyebrows in a “OK, then” gesture and leaned back. Miroslav dove in and tried to remember where the arrow had been on the photography in the book.

“Yes, that’s it” Marissa said, confirming to Miroslav he had probably found the location.


“What’s wrong” Marissa asked, when Miroslav stopped.

“Oh, I thought we were done. That was it, wasn’t i?” Miroslav asked.

“Yes. Yes, it was. Good” Marissa said, in a neutral tone.

“Male” Miroslav read from the book, it was the next subtitle. They looked at each other briefly and there was a hint of smile or small laughter, which they both ignored and read the next section about the male genitals.

Males can be aroused by stimulation to the sides of the glans and penis, upper side of the glans, the foreskin and the front side of the scrotum.

The photography had arrows pointing out the location of each term used.

Marissa held out her hands in a “OK, let’s see” gesture. Miroslav nodded, stood up and pulled his now half-erect penis out. “It’s normally a little smaller than that” Miroslav said, just so Marissa wouldn’t get her facts distorted by his erection. Marissa nodded and hesitantly put her mouth on his penis.


Marissa looked back in the book, and attempted to find all the locations mentioned. “Glans?” she asked Miroslav and looked up. “If you get the head in, I think those edges are it”. She tried that slowly. Miroslav closed his eyes and nodded a “Yes”.

“That’s all of them, then” Marissa said and leaned back again. Miroslav stood for a second confused, then saw Marissa reading the book again and he sat down. “Good” he said. “What’s next?” he asked, probably seeming a bit too eager.

“2 more pages left” Marissa said and turned to the second last page.

“Intercourse” Marissa said, reading the title of the page. Miroslav started reading the parapgrah aloud.

“Sexual intercourse, or coitus or copulation, is principally the insertion and thrusting of a male’s penis, usually when erect” Miroslav paused for a short moment, pointed down and said “Check”, then continued reading “…into a female’s vagina for the purposes of sexual pleasure or reproduction. This is also known as vaginal intercourse or vaginal sex.”.

“Coitus?” Marissa asked, trying to get the correct terms just right. Miroslav nodded “And copulation”.

Marissa hesitantly leaned back again. Miroslav, slightly less hesitant, it seemed, eager to get some practical experience. He slowly moved it in. It was not very difficult, both of them having been warmed up quite a bit beforehand.


“That’s weird” Marissa said. Miroslav could hardly speak “Oohhh … whoa…” he said unintelligibly.

Marissa read a bit from the book “… the insertion and thrusting of a male’s penis” she said. Miroslav decided it was time to try out one of those thrust thingies and pushed his penis all the way in as Marissa gasped. “Whoa” she said “Yes, I think that was a thrust, you got it”.


“Yes” he said and thrust again. “OK?” Marissa said. “Yes, this is it” Miroslav said “This feels exactly right” and he continued, thrusting faster and faster. He lifted Marissa up so he could get even further inside her, then he continued thrusting. All of a sudden he started feeling the rush of an orgasm, it was nothing like masturbating, this was the animal in him, millions of years of evolution supported that this was exactly right.

He came.


“What happened?” Marissa asked.

“I’m done” Miroslav said and pulled out, cum flooding out, landing on the floor.

Marissa didn’t notice it, she just felt wet down there.

Miroslav sat down and caught his breath while Marissa looked back in the book. “I guess that’s it for this page, only one more page left” she said.

She turned the page and read out the headline.
