it slipped

I live with my gf and her sister in an appartment. My gf wasn't home. I pulled my cock out of my pants and covered it with my shirt, long story short, I pusshed my luck, and my gf's sister saw it. I hope she thinks it was an accident. She acts normal but i hope my gf doesn't hear about this. God dammit
