[Maruarai (Arai Kazuki)] Commuting Housewife (Bokutachi wa Benkyou ga Dekinai)

A flustered teacher finds herself trapped in a steamy encounter with her earnest student after a plumbing mishap leaves her waterlogged and dependent on his help. As she calls him Yuiga-kun and he insists there's nothing to be embarrassed about, the situation between the busty, beautiful Kirisu-sensei and her young charge escalates from apologetic closeness to an inevitable, passionate tumble. The tension builds through teasing dialogue and shifting power dynamics until she surrenders to her own arousal, leaving the once-proper educator breathless and blushing beneath the boy she was supposed to guide.
