The super-cute stepsister from my parent's remarriage is always in a defenseless state, showing off panty shots and cleavage! She comes to cuddle or touch me, driving me crazy! Before I knew it, she caught me with an erection and I had to explain 'Actually, I'm a virgin...' She saw my erect dick and got excited, saying 'If it's just a little, it's okay to do something lewd!' However, the act gradually escalated! My stepsister came so hard that her legs gave out, spreading her legs obscenely until my dick couldn't get hard anymore, she kept demanding it inside her over and over!
