The Sleepover Ch. 04

Lauren's moans of pleasure are music to my ears, as she lovingly sucks my cock deeper into her warm mouth, with ever increasing speed and more saliva. She has been going at it for over ten minutes now, and even after more than a year of her providing me with amazing oral stimulation, she still manages to surprise me with her sheer will and endurance to just keep going. Day and night, anywhere, anytime.

"Oh my god." I gasp loudly. "Holy FUCK, Sis! We can't stay here for much longer! You have to wrap this up!"

'Here' being the small but surprisingly clean bathroom of my sisters' high school, at which currently the graduation ceremony was taking place for this year's senior students. Lauren, sick of waiting for nearly an hour before she would be called on to the stage and accept her piece of paper representing her years of intensive study hours (the last couple of months these hours having been interrupted with mind-blowing sex involving her own brother and her bestie), convinced me to sneak off for a bit and make some really fond graduation memories: with the flimsy excuse to mom and dad (mom really didn't seem to buy it, but whatever) that Lauren wasn't feeling well because of the nerves, I accompanied her to the girl's bathroom, where she, immediately after flicking the door shut, dropped to her knees and pulled my hard cock out of my pants.

Still wearing her graduation gown and that goofy hat, she had opened the first to reveal to my shock that she was wearing nothing but the red thong I gave her for her 19th birthday a month ago. The thought of my sister being naked underneath that gown in front of half the school this whole time, was then quickly interrupted by the heavenly sense of pleasure that only she could provide, once she started her world-class blowjob. Even after 14 months of almost non-stop sexual pleasure with my sister, she could still bring me to climax like no girl ever achieved. I prayed said climax would arrive soon, as we would need to go back to our seats before Lauren's name would be called.

"O, Relax." Lauren said with a grin, after she pulled her mouth of my cock with a loud pop, and proceeding to jerk it furiously between sucking. "You know my name is usually at the bottom of these attendance lists. We have plenty of time. And I want you to cum on my face before I go out there!"

Stroking my cock even faster after that, I felt she wouldn't have to wait long for that graduation present: my nut sack swelled, my legs started shaking, and Lauren chose the exact right time to stare up at me with both the cutest and utterly slutty porn star smile in her eyes I had ever seen.

At that moment as my cock unleashed my load of potent seed on my sister's sweet face, wide open mouth, tongue and beautiful perky tits, as I cried out and could vaguely register her own "Yes! Oh yes! Give me all your fucking sperm, Brandon! Paint it all over my face!" I knew that I never wanted anyone else to share my life with; my sister's sexdrive was simply unmatched, and there was nobody I loved more right now than my own sexy sibling. There was only one fitting path forward to continue this state of absolute bliss:
