“No... don’t touch me there anymore!” My sister is right there! Fingered so deeply... I won’t be able to keep quiet! --Rinko is a nurse who takes her job very seriously. One day, she finds out a patient of hers is her younger sister’s boyfriend, Mashiro. She goes to see him on her rounds and ends up walking in on them about to get hot and heavy. “If you need someone to wipe away your sweat, you can ask us nurses. We’ll do anything to help you.” “Anything...?” Mashiro then asks Rinko to help him out with his ‘situation’. Rinko declines at first, but is coaxed into ‘relieving’ Mashiro of his pain... but then Rinko’s sister comes back!! Rinko finds herself hiding under Mashiro’s covers, with his fingers making their way to her panties... Can Rinko keep her screams of pleasure down so her sister doesn’t find out?!
