Yu Narukami has been living with his uncle for a month now, he's been getting along well with him and his daughter, made a group worth of friends, and was generally having a pretty good summer. Today Dojima had actually been away from his job for long enough to spend the day with his family, and Yu and Nanako were delighted to visit the beach with him, Nanako had only ever gone once at that point, and it happened when she was too young to remember it. The three of them had a near-perfect day together, the weather was just right. They took a picture together, standing infront of the water, big smiles on all their faces, it was such a warm moment captured so perfectly, and the picture is certainly getting framed and going up on Dojima's desk.

That is, once he's done masturbating to it. As Yu was currently mortified to have caught Dojima with his pants down, his hand on his cock, and his eyes locked in on the image of his family that was taken earlier today. Dojima didn't notice Yu at all, his focus was entirely directed at playing with himself. Yu simply froze up and covered his mouth with his hands as his eyes widened. Dojima beat his cock in the middle of the living room like he owned the place.

"You look so good in that swimsuit..." Dojima muttered to the image as he stroked himself, Yu wondered if he was doing it to the image of Nanako, or of Yu himself, neither option seemed particularly acceptable but he'd be more than happy to bear the burden of lust if it meant little Nanako was spared. He listened closely for more comments on Dojima's fap session, but he remained silent, the only sound in the room being that of his uncle's hands beating against his balls with every flick of his wrist.

Yu wondered what he should do in a situation like this, not knowing whether or not Nanako was in danger, how Dojima would react when confronted, how to deal with his feelings of secretly being turned on by the sight of Dojima jerking his cock. Yu was still growing, but seeing what Dojima had completely destroyed any pride he had taken in his own size. He just wanted to have that...

Dojima whispering to himself that he was about to cum made it obvious to Yu that he was going to have to leave before he was discovered, yet still, he couldn't look away, his eyes were drawn to that dick like Dojima's were to the picture. Dojima bit his bottom lip as his orgasm came, he squirted all over the image, his hand stroking as fast as ever through each spurt. His semen ended up everywhere. Even once his dick had been throughly milked, he still went for a few pumps.

Realizing what he had done, he left the room to grab tissues to clean up with, fortunately avoiding Yu for just long enough for him to investigate the crime scene. He looked at the cum-soaked picture, as it layed there on the table, he saw Dojima's dick milk stain only one part of it, the sight of Yu in his yellow swimming trunks having been stained by the load of his uncle. Yu had known beyond any shadow of a doubt, his uncle spent his night jerking off to pictures of him.
