@chaoticnote No, more like she'd think he didn't like her and was coming up with a bullshit reason to turn her down rather than just reject her out right. That and girl is VERY horny...and she just seen the object of her lust/love/affection is also turned on by her. I doubt it'd be such a simple thing for her to stop.
Idk why people are so made about this premise, I'm happy to read a harem manga that explains why everyone is just so interested in MC's dick.. and it's hilarious
