Go back to his room and jerk off

The lust of the morning was getting to Yuto's head, and he couldn't contain it. He was painfully aroused and could feel his erection growing in his pants from even looking at Shiori. Shiori seemed to notice and had a sly look on her face, but Yuto turned before she could say anything. He began to walk back to his room, determined to get back in control of himself. Shiori called something to him from back in the livingroom, but he ignored her.

Once he got back to his room, he locked the door, pulled out his laptop, and took off his pants. Yuto went to his favorite porn site and thought about what he wanted to jerk off to. Thoughts of moments before with Shiori pushing her tits together guided him to one of his favorite pornstars. He searched her name and clicked on the first video he saw. She was getting fucked from behind by a man while he groped her massive tits.

Yuto's thoughts went back to the sounds he heard this morning, and he unconsciously started imagining the two in the video as Shiori and Ieyasu. Every time the male pornstar in the video groped at his partner's tits, a surge of lust and jealousy overtook Yuto. All Yuto could think about is how undeserved it was.

_"Ieyasu was a good for nothing scumbag. He didn't deserve to be pawing up Shiori's tits. I deserve them much more," _Thought Yuto to himself, pumping his erect cock, but then, he reconsidered.

"Still, I need to look at the facts. I'm sitting in my room jerking off when there's two bombshells lounging around a few rooms over. I bet Ieyasu is already in there chatting both of them up now,"

For some reason, instead of making Yuto feel ashamed, the thought of that made his arousal spike. His repressed desires were creeping up on him. His thoughts made him reframe his imagine of the sounds he heard earlier. He thought less about how sexy Shiori was. His thoughts shifted to Ieyasu dominating her. Thoughts of Ieyasu fucking her to the point where the entire house could hear the two of them._ _Thoughts of all the times he'd seen Ieyasu's fingers paw up Shiori's tits in public. Thoughts of all the time Ieyasu had clearly tried to get into Yuria's pants.

Yuto's cock was throbbing with arousal and he was on the edge of cumming. Instead of continuing, Yuto tried to reel himself back. He didn't like where his thoughts were going at all. Ieyasu was just another fuckboy. He lucked out with Shiori, and he'd get nowhere with Yuria. Yuto kept reminding himself of how **** and pathetic Ieyasu was.

"I bet the only reason Shiori even dates him is because he has a big dick or fucks really well or something," Yuto thought to himself.

Again, however, Yuto's thoughts betrayed him. Instead of thinking about Ieyasu's belittled character, all he could think about is Shiori's lust for him. His thoughts shifted back to the sounds he heard this morning for the third time, and this time, it was accompanied by the porn video. In the video, the actors have definitely started heating up. It was less some gentle fucking and groping, and now more of what he imagined Ieyasu would do to Shiori.

Yuto's arousal began to surge again. The female pornstar came passionately as she was getting railed from behind, and all Yuto could think about was that morning. Yuto betrayed himself and began to pump to the video. His mind, however, was elsewhere. All he could think about when watching the girl in the video cum on the man's cock was Shiori. He thought of Shiori orgasming all over Ieyasu's massive cock, and begging for more. He imagined Ieyasu pinning Shiori down and making her scream his name. Lastly, he imagined him finally succeeding in getting Yuria alone and showing her what a real cock was capable of.

With his thoughts swirling, Yuto's cock erupted. He had one of the most potent orgasms of his life, and it was all while he was imagining his girlfriend getting plowed by a fuckboy. A mix of deep shame and euphoria washed over him as he shot out his huge load. Then, once the euphoria and arousal was gone, all that was left was shame. What just happened? Why was he thinking like this?

Perhaps because he thought the reason wasn't all that important, or perhaps because he was afraid of what he'd find out about himself, he decided to ignore his previous train of thought. He simply cleaned up, got his pants back on, unlocked the door, and went on with his day.
