In a private harem meant for fattening up beautiful girls, two step-sisters- Cara and Kaiia- have just arrived. I have been put in charge of Cara, and is instructed that I must fatten her up for Master or else she'll be sold! So every day I come into Cara's bed chambers' and makes her to eat- despite Cara's protests. Today I came in with all sorts of fattening foods, pasta, garlic bread, a milkshake, and lots of cakes for dessert! I start to make Cara eat as she is tied to the bed. I am constantly talking convincing her into taking bite after bite. Finally, Cara has had enough and pleads that she must be fat enough for the Master now because she has gained so much weight! I am not quite sure yet, and I decide to test Cara out to make sure that she is ready. I come back with the only way to test if Cara is ready: by fucking her with huge strap on I tell Cara that this is her test so get ready! To Cara's dismay she rolls on her back to let me fuck her tight, young, and wet pussy. I fuck her, touching her soft body and commenting on how soft and fat shes gotten all over! The whole time I fuck Cara she can't stop shoving the tasty deserts down her throat. Cara finally climbs on top of the monster cock, which in turn makes me orgasm. Cara then cums too and we both collapse exhausted from pleasure..... But I have to let Cara know that it wasnt enough, she isnt fat enough yet, and she will continue eating all of the meals I have to bring her every four hours.
