Naru wants to help set Umino up with Usagi but worries about how well their first time might be. Long story short she takes his virginity so he’d have some idea of what it’s like to bang someone

Umino wasn't sure whether it was a good idea for Naru to have sex with him. Practise, she had called it, for whatever girl he might try to please in the future, but that didn't sound right to him. Not that he said that to her. In fact, he didn't say anything, just sat there with an equally flushed and excited face as she undressed herself in front of him, revealing to him his first sight of ample teenage breasts and lightly haired snatch. His first sight in the flesh, anyway. As he had been assured, pornography did NOT count.

His hands found their way to her chest before she gave him permission to touch them, but to be fair to him, she had also just taken her place on his lap, her hands fumbling at his pants to get him out of them. She seemed to be in a rush, and the anxious part of him was too pre-occupied with the soft feeling of breasts in his hands to possibly take that as an insult, even if, in reality, it only represented her own neediness. His cock same out. She wrapped her hand around it, aimed it up, then took her place atop it, before sinking onto him.

Just like that, he had lost his virginity. She had never told him whether she was a virgin or not, but he assumed that she wasn't. It was probably for the best that he didn't look between them to see the blood trickling down his member. If he had thought that she was a virgin too, he might not have immediately buried his head into the nape of her neck and then started hammering away at her pussy as if his life depended on it. Considering just how good it felt to her to finally have him inside, it very well might have.

Umino was every bit as desperate as a nerdy virgin would be, and the way he slammed up against her time after time meant that he wasn't going to last very long, either. Naru knew that certain parts of his technique were sloppy, but criticising him fell by the wayside as her own orgasm hit her like a truck. As her spasming pussy throbbed around him, he came, filling her womb with cum.

And it was only as she lifted up off him post-orgasm that she realised that he should have put a condom on. Whoops.
