Jennifer woke up groggy and tired, her body still recovering from the hours she spend laying eggs. She couldn't believe how quickly she'd fallen beneath her sisters, harpies must be quick to find weaknesses. Jennifer gasped as Serene suddenly appeared over her. "Ah, it looks like your awake." she said, her face merely a few centimeters from Jennifers. "You were so busy yesterday I thought you'd be crashed out all day." Serene pointed with her nose to a corner of her room, following her gaze Jennifer saw an impressive pile of eggs all stacked. "That was all you, it was.....very impressive." Jennifer could hear her sister holding back the lust of the last few words.
"That was all me?" Jennifer said in disbelief, there was easily twice the number of eggs than before, had she been laying even while asleep?
Serene stroked her cheek down to Jennifers naval. "Yup, and I have to give it to you, I love it that you can't control your lust." Serenes voice dripped with venom covered in sweet icing. "It reminds me so much of humans."
"I bet." Jennifer replied nervously, sure in this reality she was born a harpy, but her brain was still a humans, and that simple switch in body language was enough.
"Mother said you could stay here all you wanted." Serene began to scroll her tongue up Jennifer's chest. "So tell me how much you want to be my little egg maker."
The feeling made Jennifers body shiver, her stomach already beginning to incubate within her as her stomach began to swell. Fuck Jennifer thought to herself, I need to control this quick!
Serene felt her sisters stomach rise as she grinned, moving down as she began to eat Jennifer out again. The growth only growing faster as Jennifer couldn't control her feelings still. Curling her lips she took the sign as an invitation as she continued to service her sister. Her own lust failing to be contained as she began to grow her own egg, her stomach beginning to jut out in quivering expectation.
Jennifer squirmed as she wrestled in her mind, she still thought she was human, and this was obviously too arousing, she had to find a way to distract herself or else she really would end up she really would end up Serene's egg slave, trapped as she spent everyday making eggs. Jennifer moaned as the train of thought crashed as three eggs pushed themselves out back to back, Serene's own egg crowning as she reveled in her new plaything. Jennifer closed her eyes, this was it she had to use the opportunity to break free!
