DOCP-201 - My little sister walks around the house naked, so I couldn't hold back and just shoved it in

Seriously, does this make sense? My little sister walks around the house almost naked, and her body is insane. I'm constantly struggling to hold it in, but with our parents gone, this is my chance! I pounced on her, and although she was shocked at first, we're siblings, so the chemistry is off the charts. We both went crazy feeling each other until we reached the climax.
