It had been a rough couple of weeks for both of them, but Anne suspected it was more so for Megan. That first night, they had probably both expected there would have been some traditional sex, yet a week later it still had yet to happen.
The reason for that was very simple: it was impossible. Megan's cock was nothing short of colossal, and colossal as Anne herself was, she had never in her life imagined having to take a cock like that. As such, her biggest dildo was about an inch shy in girth. She simply had never been stretched even close to the size of Megan's monster.
Even in spite of that, sex between them was still fantastic. Every day- and often several times- their small two-bedroom apartment had been filled with the wet slap of flesh on flesh. That thick, chocolate-brown cock had slipped between her breasts, her thighs, the crack of her ass, and in the crook of her bicep. To say nothing of her hands, and her lips- as far as they were able to fit, at least. Her biceps were rather impractical for the task, but man, did Megan explode when they tried that. There was no hiding the fact that Anne's muscles turned the small futa on to no end. As for Anne, her favorite was when it was sandwiched between her thighs (which she had learned was called "intercrural" sex the day before). When Megan thrusted in there, her meat slid across the amazon's clit in the most delicious way, quickly coated in the juices that form of sex drew out.
Of course, Megan had done her own share of making Anne happy, that was for sure. She had fisted her on more than one occasion, and wow did that make Anne see stars. And the hapless dickgirl seemed to be drunk on her pussy, because their encounters rarely didn't include a hefty serving of cunnilingus.
But that was the past. Today would be the day. Anne had gotten creative, and enlisted Megan's help, working out how to stretch her out, and today- today!- she was determined to make it happen.
... That was the fourth time she had gone over the facts in her head... and not the first day that had happened, either. Blinking away the thought, she focused again on the board. Fortunately she was an excellent note-taker, and often wrote them down without thinking about it, bypassing her upper brain functions entirely. But her chair was creaking distractingly with the way she occasionally squirmed, thinking about what was going to happen. The students seated around her had gotten used to it after the first week of this behavior, and simply carried on following the class.
For the fourth time, she set her mind on what exactly it was she was jotting down again, and put Megan from her mind.
...
At the same time, Megan was drumming her fingers on her desk. She was remembering the time, about a week prior, that they had first tried penetration. She insisted it was impossible, Anne insisted they try anyway. Megan had pushed with all her strength, to no avail, then Anne had tried to sit on it, to similar results. She had gone slowly, careful not to snap Megan's dick in half, but the pain in her face was clear, and they stopped. It was close though, and Megan had almost shot off right then and there, head half inside that tiny pussy. Well, tiny be only her standards.
She exhaled slowly and forced herself to think about her own class, before her dick could start to rise. She wondered- not for the first time- if there was a way she might be able to cage it to avoid erections being a problem. At least she could only get so hard without seeing and touching Anne with most of her skin showing. It was distracting and uncomfortable, but manageable.
God, she could not get home soon enough.
...
Anne had her key in the lock when, through the railing, she spotted Megan walking toward the apartment complex. She suddenly found a spring in her step as she slipped inside. She had to be quick, she only had a couple minutes.
Megan had a spring in her own step as she came in. "Are you home yet, Anne?" She asked as she shut the door. She didn't get an answer, which wasn't unusual. Their classes ended about the same time today, so she would probably be around soon. She grinned and kicked off her shoes. She had hoped to be home first, so she could surprise Anne with something sexy.
Right there in the living room she pulled her leggings down, along with her straining underwear, letting her dick breathe. It swung free between her knees, soft for now, but that was about to change, she was sure. Still wearing her baggy sweater, which disguised her cock handily on most days, she sashayed toward her door. How she had managed to go around fully clothed all the time before she and Anne hooked up, she couldn't even remember anymore.
Then the lights in her room went off. She hadn't noticed it, but they had been on when she had come in, and just now under the door she saw them go off. "Anne?" she asked hopefully.
She didn't get a verbal answer, but she did get something. The answer came in the form of music suddenly starting on the other side of the door. Acoustic guitar, was... was Anne playing in there? For her? Megan was suddenly overcome with a mix of a variety of feelings. But rather than stand there and try to sort them out though, she simply opened the door to find out what-
Anne flashed her a big smile from her spot on the smaller girl's bed. She was much too big for it, but sitting against the wall as she was, one leg extended, the other flexed lazily next to it, she made it work. The light was out, but she was visible there by the light of several candles she had set out, which made every groove in her muscles dance. And lucky for Megan, every muscle was on display. Lacking, as a student, the money for expensive lingerie, she had made do with her bikini, custom-fit by her own hand, white material pulled tight across her soft tits, and disappearing between her thighs.
