How big is she going to make you?

Your belly is growing much faster now. Quickly pushing you back onto your knees as it surpasses looking overdue with quadruplets. Meanwhile Sam is in her own little world. She's giggling and stripping off her clothes as your stomach expands horizontally in every direction, the forces of gravity finally overpowering the perkiness of your biggest feature.

Now fully stripped, Sam grabs a bottle of baby oil from her bag. She pours some on your vast (and still growing) stomach and starts rubbing it in. With a belly around two and a half feet tall and four feet in diameter, your skin is very stretched out. The enthusiastic rubbing by Sam is a delight to your very sensitive stretched skin and draws out more than a few moans from you.

"Sam mmm please mmm no more mmmmm..." you beg her to stop as the bigger you get the more sensitive your skin is to her skillful rubbing.
