Sunlight flowed from the window warming Ty's beautiful face, however it was not this warmth that woke her from her sleep, but the warmth around her cock. Ty knew this warmth, this wet and pleasurable warmth, it was a mouth the mouth of an expert cock sucking slut. Opening her eyes Ty saw a beautiful F cupped foot long dicked futa, instantly she knew this futa was Dustin and her mind filled with new memories.
New memories of sex, and of love, of stripper pole dance lessons, and slutty competitions, and of course new memories of dates and fucking with her now biological sister Dustin. Dustin, or rather Dusine, was Ty's girlfriend, they were in an open relationship of course, they were free to fuck or be fucked by anyone. They could even fall in love with someone else, but they would always love each other, they would always love their incestuous sex, they would always love the same futa's together, because that's what it means to be girlfriends in this world.
Ty enjoyed her girlfriends blowjob, letting her suck with all her might, eventually she couldn't help but to buck into her sisters mouth, getting closer and closer to climax. Dustine could sense her girlfriend was on the edge, and slowed down, wanting to make sure her girlfriends pleasure lasted as long as it could. Moaning and groaning Ty was on the edge, ready to cum at any second, her balls churning out more and more cum when finally she sensed it was time and with a single mighty thrust into her incestuous partner Ty came.
Cum flooded Dustines mouth, and rope after rope of cum she swallowed every drop with an expertise developed over years of slut training, and her natural instinct as a Futa. After several minutes of cumming Ty was done, and Dustine got off of her cock asking "Did you enjoy Slutty?" "Of course Dusty, you give some of the best blowjobs." Ty answered "Thank you." Dusty responded as she climbed up her lover. The two were face to face, their massive boobs pressed up against each other "So where are mom and dad?" (Dad being the Futa that impregnated Mom) Ty asked "Down stairs entertaining some "Guests." Dusty answered "Want to go down there and join them?" "Well if you want to, or we could do something else." "Like what Cummy Bear?" "We could go to the club, schools filled with lots of sex, I think one of our friends is having a party..." "So many choices, what to do?"
