A/N: I just got bored, so I thought I'd make this. I do not own AT. Sorry this is just my own thought. OH! But Taylee is mine. Incest and Yaoi. Don't read if you don't like.
"Marshall Lee get out of my room!" Prince Gumball instructed firmly. Marshall laid on Gumball's bed smirking at the young man that entered the room. Gumball steps forward and grabs Marshall's arm. He yanked on the young vampire, but unfortunately could not get him to budge.
"Marshall! Out!" Gumball yelled again.
Marshall Lee smiled and looked straight at Gumball, "Why should I? Your bed is so soft and I know you like my sister, Taylee. Would you let me stay if I brought Taylee over to 'play' with us?" Marshall winked, which made Gumball blush deeply.
"I guess you could stay if Taylee came by," Gumball muttered softly. Marshall floated over to Gumball and rubbed his chest.
"Tails get your ass out here!" Marshall hissed into Gumball's ear. Taylee pushed out of the closet, floating over to the boys. Taylee immediately came up behind Gumball and dragged her fangs along his neck. Marshall laid back on the bed, letting Taylee get started. Taylee sucked on the young prince's neck, thinking about biting him, but she had to wait.
After a couple minutes of that, Marshall floats over and starts rubbing Gumball's cock through his pants. Gumball moaned while Marshall rubbed him. Taylee dragged her fangs over his collar bone, traveling down his chest. Gumball tried pulling out of the twin vampire grip, but was unsuccessful. Marshall undid Gumball's pants, while Taylee pulled his boxers down. Taylee pushes her brother out of the way. She leans forward and starts lick the underside of Gumball's surprisingly big cock. Marshall came up behind his sister, pulling off her red and black plaid shirt, her black T-shirt, and her black and red plaid bra.
Gumball blushed a deep shade of red, as he watched the younger of the twins suck his cock, while the older one rubbed the younger one's large tits. Gumball pushed Taylee's head back, making her stop. His breathing was insane. Both vampires immediately stepped towards Gumball again.
"Please let me suck you Prince Gumball. Pretty please!" Taylee whined leaning forward again. Gumball climbed onto the bed and said,
"Suck you little vampire slut." Marshall grinned at his sister, as she climbed onto the bed following orders. Taylee sucked hard on Gumball's hard cock. She gently massaged his balls as she sucked. Marshall undid his pants and slid his boxers off, then pulled Taylee's jeans off, along with her thong. Gumball pushed hard on the youngest vampire's head making her deep throat him. Gumball watched Marshall line his huge cock up to Taylee's pussy.
"Taylee you're about to be fucked," Marshall purred into his sister's ear. Marshall fucked her little pussy hard as Taylee kept sucking Gumball's cock. After what seemed like a year, Marshall came in Taylee's pussy, and he pulled out. Gumball came hard into Taylee's mouth spraying long, thick streams of cum down her throat. Taylee swallowed it all, passing out at the bottom of the bed.
"Thanks Marshall that was… Amazing," Gumball praised. Marshall lifted up his sister, and laid down next to Gumball laying Taylee between the two of them.
"You said I didn't have to leave I thought Taylee should be allowed to stay too," Marshall kissed Taylee, then Gumball. Gumball then kissed Taylee then Marshall.
"I love you, you perverted vampires."
