Koorimachi Wakana's Enticement

At this rate both of them are meant for each other. A little push in another sequel and this might get a vanilla ending.

I love this series. Wakana and Tomoya have the most interesting
fuck-buddy relationship on Fakku.

She's a serious, self-conscious introvert who's never fucked anyone
except Tomoya, and he's a cheerful, extroverted horndog who fucks
around with all the girls. They could hardly be more different.

There's no love between them. Wakana basically tolerates Tomoya because
he's a good fuck who knows how to scratch her itch. He, on the other hand,
seems to be genuinely fond of Wakana specifically because she's somewhat
repressed, and her reluctance adds zest to their sexual adventures.

I'd like to see further chapters, in which Tomoya involves Wakana
in ever more perverted shenanigans, like taking her for a midnight
stroll in the nude, and freaking her out by fapping outdoors.
