Fatter where it counts.

Kary sways lazily. Her motion translates to her massive swelling cock wagging at you.

“Well, bro? Do I look fat enough for you? Or are you just staring at my dick again? Not even a little interested in my belly?” Kary feigns disappointment.

“I’m sure your mind isn’t on your belly, Kary, but how we can make mine match its size! It is going to *cum* from my fat sister’s fat cock!” You say seductively as you trace a finger over her cock, making it jump. You lean over and lick up the bead of clear fluid that beads up as your reward. “This thing has gotten larger, but I’m sure I am catching up.”

“Looks like my brother’s airbags went off...in the front and the back!” Kary ogles you.
