[Reducing Mosaic]MASM-001 Defeated by my bratty niece shouting 'zakozakosaa~ko' at me, I was reverse milked and fell into M-hood. A story by Matsumoto Ichika

I ended up taking care of my niece Ichika for a week. Even though I cooked her dinner, she said things like 'I don't want to eat! Order takeout and lend me your credit card!' She's just an insolent little brat. I thought about teaching her a lesson about talking back to adults... but instead, I got pushed down and made to finish inside while she was on top! 'If Dad finds out, you're dead,w' Now I can't go against this kid... The start of my daily hell of having my sperm milked.
