Flubbin First Prize (Patreon)

Maddy has entered her science project, Flubber in a local contest. As she is showing Flubber off, it escapes and bounces around the room before flying down her throat and into her belly! Maddy bounces around with Flubber inside of her until some time later - she finds out that Flubber has impregnated her! When Maddy's water breaks she's in for quite a surprise when she finds out how many Flubber's she's giving birth to!
