Clumsy girls can be quite cute, and I think in her case, a bit of obliviousness/cluelessness, too. Especially the way she nonchalantly discusses masturbation and such with him.
And in a sweet Vanilla release like this, it just makes them all the more endearing.
Hmm, on page 7, did she unbutton her top only for it to magically close on the very next panel on the left? And then it opened up again right after?
I suspect relatives, friends and future offspring will be either fascinated or stupified if or when the details of how these two hooked up are revealed.
Nonetheless, it was cute enough to get the job done.
