No, he slides down

As Sally was just about to push the cucumber deliciously into her entrance, Flubber moved along her skin to hide from the huge phallic object.

He instead found a different hole, more ridged and puckered for himself to hide away from the large green monster. He started to poke his head inside of it, just taking a peek before Sally was slamming the cucumber inside of herself. She thrusted the vegetable in and out viciously, chasing her orgasm.

Flubber got more and more nervous on how the cucumber was attacking poor Sally, so maybe he could help her by going inside of her other cave entrance.
