The middle door

The aliens open the middle door, leading you into a white room with several other doors around it. They smirk as they lock you in, but you're too horny to notice. Your pussy is dripping and your tits are tingling. You start rubbing your clit with a finger, kneading a tit as you slowly finger yourself. But it's just not enough; you soon need more. You start increasing the pace, pushing fingers into your pussy until you are fisting yourself. Your orgasm comes like a crashing wave, pulling you under as you buck like crazy.

When it finally stops, you realize you've changed. Somehow they have now made you into an animal hybrid.
