HHKL-038 - “Are you avoiding me?” My little sister barged into the bathroom and things got out of control.

My innocent little sister is obsessed with me, but since she's my absolute type, I've been struggling to keep my distance. One day, she barges into the bathroom to 'scrub my back,' and the physical contact in the small space makes me lose control. Expecting her to be disgusted by my reaction, I was shocked when she started teasing me, saying she'd do anything to please me and begging me to touch her sensitive spots. I ended up driving her crazy until she couldn't stop climaxing.
