finally opening her eyes again, I leaned in again, "I know you like my cock up in you, you little slut. You tease and tease, but now you get what you have been pining for, hmm!!" I said the final word aggressively as I gave her my hardest thrust yet, picking her up onto her toes as my cock explored as deep into her as it could reach. "Fuck Marc. Oh god, we don't have much time!" "I will finish when I am god damn good and ready!" "Marc! Don't cum inside okay? Please? I don't want to worry about getting my period." She begged me in a hushed tone, starring at me, pleading with me in the mirror. I looked down and grabbed her hips, I was already getting close and I wanted a good hard fuck to remember. I gripped hard and began to slam back and forth, faster and faster until my testicles were slapping up against her pussy where my cock was disappearing inside. I loved the sound of our bodies slapping together, and flipped on the bathroom fan to muffle the the noise a bit. I also was mesmerized with the goo that was stringing from my genitals to hers. It wasn't my cum, so I wondered if it was hers. Speaking of which, my balls were starting to tingle, I was finally going to have a clear free cum inside my gorgeous little step sister, and I couldn't wait , actually wanting to cum faster. "Becky! Are you ready? We are gonna be late!" I heard my step mom holler from downstairs. Becky pulled the door open a bit. "Al-almost r-r-ready mom-mm!" Becky yelled back, trying to sound normal. ...

It was about a minute later when we heard. "Dammit Becky we need to go!" And we could hear her mom's steps coming up the stairs. Becky looked at me in the mirror with a look of horror and her hands went behind her trying to push me away. "Marc, Marc we have to stop!" She said as loud as she dared. Little did she know, when a man is that close, he is gonna finish. I wrapped my arms around her waist and leaned onto her and said into her ear. "Here is my cum baby, thank y-yuuuuuuu!" With that I snorted as my balls clenched and sent a torrid wave of cum up my shaft and into her waiting womb. Spurt after spurt as my penis clenched again and again over the next 10 seconds. I felt Becky's body spasming beneath me and knew she was experiencing an orgasm with me, together in love. I could hear the creak of the stairs, my step mother was almost to the top and then a few steps to the bathroom. Even feeling that I had a little bit more cum to give I forced myself to push back from Becky and watched my cock bounce free of the lips between her hips. I was shiny from the slick of our juices and I saw a last little spurt of cum plop out onto Becky's ass cheek. I stumbled to the toilet room and pulled the slider door closed, careful not to slam it and let her mom know I had just gone in. Becky in a rush, her face flushed, her clit ...
