[Nice Tack] Don't Tell Keine! (Touhou Project)

Fujiwara no Mokou takes pity on a young village boy who's wandered in, and what starts as a guilty, hands-on apology—foreskin lesson included—spirals into her riding him before he flips the script, too impatient to go slow and desperate to bury his virgin cock inside her. Round two kicks off when the sight of her plump ass bends her over for a frantic doggystyle session, her grip somehow even tighter than before, all while the pair keeps their tryst a secret from Keine. The afterword lands the punchline: a cluster of blushing boys she's deflowered, while a cheerful Keine marvels at why all the village kids have suddenly grown so attached to Mokou.
