Plot: Finally, Sweetheart is going to fuck her cousin Sniffles (These two are related in case you forgot)
It was getting dark out. Sweetheart was able to make it home in record time, and had requested permission to enter Sniffles' lab. Sniffles of course granted access, and welcomed Sweet to his humble abode. Sweetheart would be staying here overnight for the next week or so. It took a while for Sweetheart to actually unpack her things since she spent the day sucking people off and/or getting pounded.
Now it was Sniffles' turn to have sex. It wouldn't be incest because they were the same age so the FBI wouldn't knock on their door at all. Sweetheart did her usual striptease for Sniffles, causing him to get a boner. At first, Sniffles was uncomfortable, and tried to hide his boner since he never had sex with a relative before.
Sweetheart forced Sniffles' arms away from his crotch, causing his hard cock to spring back up. First, Sweetheart started with a good suck to lube up his dick for later. Her slimy tongue felt like heaven on Sniffles' aching penis. Next, Sweet positioned Sniffles so he would be hot-dogging her. She then proceeded to stroke his dick with her ass cheeks, causing more pleasure.
Once everything was all settled, Sweetheart let Sniffles do the rest, as she had one hell of a day. Sniffles kept on fucking Sweetheart in the ass so hard his long dick managed to reach the top of her birth canal. After countless thrusts, Sniffles was finally about to cum. The day had been busy for him as it was for Sweetheart.
The flow of warm, sticky semen out of Sniffles' penis was the last thing that happened on that day, as the two of them were so tired, they collapsed and fell asleep for the night. THE END.
