My mother remarried, and my siblings and I gained an older sister who's a bit older than us! I was happy about my kind stepsister, but it turns out she's a lesbian who molests her little sister at night! The new house is small, so the three of us sleep in a row, and I hear lewd sounds from beside me... When I peek, my stepsister is attacking my little sister! I'm shocked but get an erection, and can't help but masturbate, only to be noticed by my stepsister...
