Super-high Probability of "Snu-Snu" taking out Souhei-kun ... unless he can toughen up. And despite her initial expression of "W.T.F, boy?", it's not inconceivable that Oohara-san either fancies him, or her inner "S" has "come out to play-yay."
Well, considering what happened, I suppose fapping in the convenience store bathroom kind of payed off.
I like how, despite him cumming after 30 seconds, she just continues as if nothing happened because she actually wanted to do something 'nice'.
Great ending though. Ahh...He may say 'no', but in reality, the answer is a solid 'yes'! Also, I think if anything, what she did will only incentivise him to continue fapping there...That, or just go directly to her from now on, I suppose.
Smells like ... A MATCH MADE IN HENTAI!
