You agree and Shelby strips down, being the smallest out of the others present. She inserts her hands in, stretching your vagina so that she can shove her head through. From inside your womb, Sara moves up somewhat.

Your vagina greedily accepts its new meal, muscles working to devour her. You feel a rush of pleasure vibrate through your bones and release gasps and yelps. Shelby's breasts are sucked in and the feel of them against your birth canal and into your womb is more than a little amazing. Her head creates a noticeable bulge at your lower belly, moving upwards.

Before you know it, she's pulling her legs in. This is the easiest part for you to bring in, and in no time at all, the swell in your stomach doubles entirely. You long for them to remain there longer than they intend to, but know that it isn't possible.

Shelby moves around behind Sara, who gets into position. "All right," the nurse begins. "Go on."

You push, slightly reluctant. This time, there's some definite movement.
