ROYD-096 I became the convenient fuck buddy for my sister-in-law who was tired of bland married sex and trying to get pregnant. Her name is Mimi Anzu.

A serious couple, my brother and his wife, are staying at our family home for a few days! They're trying to have a baby, and at night, moans come from their room! I was imagining it all while jerking off when my sister-in-law caught me in the worst situation! But she said, 'You got excited because of me...?' My brother alone can't satisfy her past slutty instincts! From that day on, she's been sneaking away from our parents and brother to demand my dick and for me to cum inside her...!?
