MDTM-413 - Can I resist my little sister's hardcore temptation? Kanon Momojiri

I returned home after a long time to find my little sister, Kanon, has become incredibly cute... and our parents are away. She's walking around in nothing but a bath towel and napping in the living room with her underwear exposed. She then creeps into my room while I'm sleeping and starts teasing my throbbing manhood. Can I really resist her hardcore temptation?
