What a cute junior-chan. I really like the artwork, so I'm glad to see more from this artist.
Hmm, clearly everything she does is purposeful, like sharing the shower stall with him, stripping and then propositioning him for sex. Or, well, literally stripping down in the middle of the road to show him cum oozing out of her pussy.
That ending though. Well hey, more exercise would tone your body a bit more to her liking, not to mention you'd build extra stamina that you seem to need to keep up with her insatiable lust, no? That being said, I kind of like this couple, makes me want a sequel to see their relationship develop more.
"Senpai" at least still seems to have enough "Mojo" to satisfy Junior-chan, ... when he gets serious. Perhaps a suitable combination of diet, exercise and *cough-cough* "psychotherapy" might raise his overall drive to keep up.
It appears to be all quite consensual between them, so I'll allow it.
