She had you at free pizza!

“Mmmm, these things were getting heavy, thank you Franny,” you purr.

Kary is munching on pizza as she watches you, rubbing her growing paunch. You see her balls refilling and lick your lips as Franny swaps nipples. You are surprised as her rounding belly slick with Kary’s pre rubs against your own.

“Franny has a great belly, just like me. No wonder she was excited to see me,” you observe.

“Like *us*, bro. Glad to see I can pump her up without breaking her.”

“I’m soo fat!” Franny steps back after draining both breasts. “Look at us! I can barely believe I don’t feel full!”

“If you want the full experience, suck off Kary while she eats. I bet you won’t be able to move afterwards,” you gesture to the leaking cock of your sister.

“Stop, you know you liked it, bro. After Franny gets it, you are next. I’m gonna pop you out of those suspenders,” she says lustfully as Franny bends over and sticks her tongue in Kary’s hole.
