[kmvt] Tohsaka Oyakodon (Fate/stay night) (Pixiv Fanbox)

Shirou Emiya's washing-machine repair at the Tohsaka Residence takes a turn when the panties he fishes from the drum belong not to Rin but to her mother Aoi, a curvy mature woman whose thick hairy armpits he soon can't stop worshiping. Their secret anal affair—Aoi shrieking as her daughter's boyfriend claims her anal virginity and pumps her full—spirals into a full oyakodon once Rin catches them and joins in seconds, mother and daughter taking turns getting pounded and servicing him together. With both women left dripping and a teasing suggestion of inviting Sakura next time, Shirou finds himself buried in an entire family's shared weakness.
