What happened next almost made my head explode. I was engaged in the kinkiest, most forbidden act of my life. I had been trying to hook up with my little sister all day, and wasn’t expecting anything to happen that would minimize the craziness of that, but it did. My mom came around the corner of the hallway, and my eyes immediately opened wide as she gasped and covered her mouth with her hand. I tried to cover myself up, but she got a clear look at what was going on. She may not have seen the pictures I had open on my phone, but there’s no way she didn’t see the pair of Ava’s panties draped over my thigh while i held my boner in my hand.
