She's Got Great Handwriting

A girl goes around town with her dad and everyone thinks she is a slut who whores herself out...

Great handwriting indeed.
But man, the classmates must read too much Hentai. See a classmate hanging out with an older man?
"GASP, SHE'S A SLUT!"...But then it turns out it was just her father. Certainly helped set up the misunderstanding for our protagonist to approach her.
Great ending though! Well hey, if she's a slut that is only slutty when she's with you...I think that is perfectly okay, it's actually a really good thing, I would say.

Yeah, that's how it usually goes. Although it looks like she did still have at least some previous experience nonetheless.

anyone else think she looks like Sango from Inuyasha, especially on page 6?

But page 14 tho?
Page 14! ꉂ (†²Ì¤à¥¢âˆ€ ू†µÌ¤à¹‘))ˉ̞̭♡

Seems that when the truth came out, Senpai's not so much into femdom but instead she's 'Rather Assertive'. And as for how or where she learned her *cough-cough* "skills", perhaps only her new boyfriend will ever find out.

APPROVED!

But where did she learn all that stuff from than?
