The panic that gripped Leah the next morning was in stark contrast to the dream-like euphoria from the night before. She immediately noticed the wet puddle of semen she'd been sleeping on, and could feel more of it still deep inside of her.
How could I let this happen?
She shot out of bed and trotted to the bathroom awkwardly, careful not to part her legs too much. The second she sat on the toilet, a big glob of cum dripped out of her. She watched in bewilderment as she pushed out more of Ethan's invasive fluids. There was so much of it, which shouldn't have been surprising given how many times she'd seen him ejaculate, but the sheer volume of it seemed far more threatening now. She had never had so much as a small accident, always visually confirming that the condom remained intact after sex, and now here she was with what seemed like ten of Josh's loads coming out of her. The potent seed had spent the entire night soaking into her, swarming her womb. She shakily tapped at her phone and checked her cycle app, which to her relief indicated that she was well outside of her fertile window.
The next few weeks were tricky. The agreement had officially expired, and Leah was back to being the normal, faithful girlfriend she was supposed to be, or at least, she was trying. It did help that Josh had regained some of his lost confidence, and seemed determined to get their lives back on track. He was diligent at work, helping around the apartment more, and even initiating intimacy with her. They would have sex every few nights, and it was getting better. Leah was also focused on improving the shared experience by being more open about what she wanted in bed, a useful side-effect of the sexual awakening Ethan had brought about in her. She was getting comfortable instructing her boyfriend on how to more effectively please her. Little by little, Josh was gaining a better understanding of how to pace himself and build a steady rhythm that could bring his girlfriend to orgasm. Leah was able to cum with him, but only ever once per session, and after much effort and focus.
It seemed that everything was going to be fine, but unfortunately, the improvements didn't last very long. After the honeymoon phase of his new job was over with, Leah observed Josh's demeanor shifting. He was spending more time at the office, and always seemed stressed about something. She made every effort to console him, and be available for whatever he needed, but he wasn't opening up. He'd even gotten short with her on a couple of occasions, insisting that he didn't want to talk, opting instead to be alone. The short-lived upward trend in their relationship had begun to take a turn for the worse, and Leah didn't know what to do about it.
In addition to Josh's own troubles, Leah, despite her determination to be faithful, couldn't help but compare every aspect of their lovemaking to the far more intense experiences she'd had with her roommate. Every time her boyfriend was inside of her, her mind would inevitably wander to Ethan and his big cock. She had learned with him that her strongest sexual reactions were achieved by fully submitting to a dominant partner, and she craved the naughty feeling of being manhandled and treated like a slut. Perhaps Josh could learn eventually, but whenever she encouraged him to take control, he would fall short of what her body truly yearned for. She tried earnestly to ignore the idea that his personality just wasn't compatible with what she needed in a sexual partner, but the thought was wearing on her mind and becoming increasingly difficult to shrug off.
What had once been more than enough to satisfy her was barely getting the job done now. Her boyfriend's perfectly average dick, covered in the smooth rubber condom, felt fine. But is
fine
enough anymore, she wondered. She longed for the overwhelming feeling of Ethan's huge, bare manhood stretching her open and making her cum over and over again. She hoped that with more time, she would be able to forget about her well-endowed roommate's skills in the bedroom, and learn to be content. That would be a whole lot easier though if the boisterous man wasn't always around. Every time she laid eyes on him she was reminded of how he could make her feel, and her body would react accordingly. He would still make suggestive comments towards her, as he always did, but now she would subtly flirt back instead of fleeing in disgust. She remembered the days when his behavior was nothing short of appalling, but it was different now that after everything they had been through together.

One morning, after Josh had left for work, Leah was sitting on the couch and planning what she would do with her free day. Ethan strolled out of his room in nothing but a small towel around his waist.
"Morning, sexy," he greeted her with a wide smile.
"Hey, creep" she replied, unable to prevent her eyes from scanning his impressive physique.
"Can I use your shower? Mine's fucked up apparently."
"Ew. Hell no," she said playfully, feigning a look of disgust.
"Come on... I'm not that gross, see?" He walked over to her and stood a foot away, invading her personal space. His scent filled her nostrils and she felt her face flush, his crotch at her eye level.
"Get out of my face, dude," Leah said with a scowl. Her gaze however, remained fixed on him, anticipating that he would try something.
"Make me," he challenged.
She looked straight ahead at the bulge that was growing beneath his towel. She knew too well the monster that lay dormant in there, and was tempted to reach for it. She ignored the wetness that was forming in her pussy, and crossed her arms, as if to lock them into place so that she wouldn't lose control. "Nice try. You're just trying to get me to touch you!"
Ethan ignored her accusation. "You look hot in that top by the way."
Leah's eyes darted down to her chest, which she had inadvertently pushed up by tightly crossing her arms, making her cleavage more prominent. She quickly adjusted herself and stammered, "Don't get any ideas!"
"Oh, I've got a few ideas alright," he muttered, while his erection continued to grow, now forming a large tent in the cotton enclosure.
