A knock at the door brought Cassie's attention away from her toys as she watched her mother waddle beneath her baby weight and walk towards the door. "Ah, you made it! And your girls are so cute today!"
Her mother came back with her three friends, Bella, Emily, and Julia, all of who were big babies just like her, wearing onesies or bodysuits that were unable to hide how massive their diapers were. Their mothers were bigger than them in their bellies. Cassie "knew" that Bella's mother was carrying eight babies, Julia's mother was carrying ten babies, and Emily's mother was carrying twelve babies. Combined with their massive milk-laden breasts and it was impossible for Cassie see their faces from ground level. Now that her mother was closer to her, Cassie realized that she could only see her mother's face from the eyes up. Until she was capable of walking, mothers to her would only be represented by big breasts and bellies and that got Cassie turned on again.
Her friends were placed into the playpen with her while the mothers rested their bodies on the couch, discussing how things had been going. Her friends were having fun with all of the toys in the pen, babbling happily. Cassie played alongside them, not caring that they didn't have any semblance of being grown-up; they were all big babies.
Cassie had so much fun with them that she wished it could always be like this. 'I wish that our mommies were married to each other and that Bella, Emily, and Julia are my sisters.'
Little changed other than hearing some kisses and occasional moaning from her four mommies.
