Mutation: tongue fucker

As you pull her head off of your cock you see her panting heavily rubbing her body whimpering, your cum dripping from her lips. Shee licks it but when you see her tongue it seems... different. You grab her chin bringing her face to yours and she opens her mouth wide revealing a tongue that looks like a ribbed fleshy rope encircled by three long forked tongues. She suddenly begins sucking on your thumb livking it insinuating that she needs to try her new appendage..
