My sis and I have been fooling around on the low for a little while now. Knowing that we are brother and sister and that it’s forbidden for us to fuck each other, turns us both on! But lately we have been pushing the boundaries, to see how far we can flaunt our taboo sexual actions…. and still not get caught. Just recently our parents took us out to dinner. During the appetizers, my sis started to rub her fingers up my thigh towards my crotch. I had to sit and talk to my mom about my why I needed a tutor for algebra, while my sis gave me a handjob under the table. I was about to explode my load all over her hands, but then the waiter brought the entree’s….and she stopped right before I could finish. This was painful as my cock was throbbing, and my balls were swelled up with cum! Sis thought this was funny….but I knew I had to figure out a way to get my release, and soon! After we finished the main part of our meals, sis decided to excuse herself to go to the restroom. My parents always order desert, so I knew I had some time to kill before we would leave for home. My balls were still very achy, so I knew I had to act quickly… Watch as I surprise my sis in the public restroom, while she is still sitting on the toilet! I lock us both in there, pull her jeans down….and fuck her right in the restaurant’s restroom! Then just to make sure she doesn’t get pregnant, I bust my swelled nuts into her open willing mouth…. and she swallows her brother’s entire warm sticky load of babies. Desert is served!!
