Before anyone gets confused by certain tags, the wolf girl Tamaki has her boyfriend mentioned through dialogue in many pages, indiriect presence asserted.

Anyway, Tamaki checks by the school doctor looking for help, she suddenly became wolf girl after having plenty of sex with her boyfriend; the doc is taken aback a little, in his thoughts he is quite mad for little brats having sex at such an age, while he calmly starts his check up to make Tamaki comfortable; everything seems to be fine with her, so the doc tells her if maybe something unusual happened when she had sex with her boyfriend Yuu?

That's where the doc fools her into repeating all steps of her time with Yuu, reassuring Tamaki that it is all to pinpointed whatever may caused her transformation and that maybe Yuu is in danger as well, what if he transforms too?

At the end the doc says there's nothing wrong with how Tamaki and Yuu had sex after all, maybe the problem lies elsewhere so doc tells Tamaki she can keep having sex with Yuu just fine, she is too dizzy from all the orgasm to properly hear him, he brags about Tamaki having superior sex than what she is used to so she is too tired, and he will take pics to use as ammo to use her again, that is blackmail fodder.
