Having cum three times already and pregnant, Scarlett was a bit slow to initiate another sex act. But McKenna had no such problem, and she knew exactly what she wanted next.
Untangling herself from Scarlett, dislodging their cocks released even more of a flood of cum, McKenna moved up behind Scarlett. Grabbing her messy cock, she pushed it between Scarlett's ass cheeks and easily pushed through her sphincter and entered her asshole.
"Omg!" Scarlett gasped, never having been anally fucked. She was shocked that the young McKenna would do such a thing, but at the same time had to admit it intrigued her.
The older blonde had never been with another Futanari, so she was surprised McKenna's full length went right up her anus. She'd read anal erotica, and knew men needed lots of lube back there because it wasn't easy going. But McKenna was fully up her ass in seconds.
Scarlett gritted her teeth from the discomfort as the young blonde fucked her as hard and fast. She was starting to think she rather have it in her pussy when she started to grow used to it. Soon Scarlett was moaning and groaning as she started convulsing. As McKenna fucked her ass harder and faster, she convulsed more violently and her head thrashed from side-to-side as she shrieked.
Suddenly her pregnant body stiffened as she threw back her head and screamed in orgasm. It was one of her most intense ever. It didn't last long, but she quickly built up to another, and another. Both blondes were hot, sweaty and breathing hard after Scarlett experienced many orgasms.
About fifteen minutes later, McKenna's cock swelled up in Scarlett's rectal channel and she cried out as she starting shooting jizz deep up her ass. Rope after rope poured out of her, as McKenna spurt out twenty-six, twenty-seven times before her balls were drained.
The eighteen year old slipped out of Scarlett and rolled into her back, smiling euphorically. She could get used to fucking other Futanari, and she was sure there were lots more out there . . . McKenna didn't feel alone in the world anymore, and the world was her oyster as it were.
Scarlett rolled over, facing the younger blonde, ready for more. Both were still hard, lots more cum to blow in and on each other. McKenna faced Scarlett, grinning. It was going to be a long day . . . THE END
