He came on the television.

Kenji stroked faster and harder as he fantasized sliding his cock into the beautiful AV actress' pussy. His wife was the only woman he had ever had sex with and yet he was imagining himself fucking another woman. He knew he was not cheating on his wife because he was just masturbating in order to give a semen sample to test his virility but yet he could not help wonder what it would be like to fuck another woman.

"Gah!" he cried out when he finally climaxed. He remembered at the last moment about the sample jar that was on the table but it was too late. The first couple jets of semen splattered against the television screen, which happened to have a plastic screen for such a reason. The subsequent squirts were weaker and coated the wall beneath the TV.

"Oh no," he muttered, seeing the sticky mess he made.

Then there was a knock on the door. "Mr. Kataoka?"

Kenji froze with his still hard cock in his hand. He was ashamed that all he had to do was give a semen sample but instead he had given into his lust and coated the television screen with his seed.

Another knock snapped him out of it.

"Give me a moment," he blurted out, stuffing his cock back into his pants. He remembered to pull his zipper up before he opened the door.
