It toys with you first

With a startled gasp from you the creature crawls over you, supporting itself on all fours above you, its maw close to your own lips. You feel lukewarm liquid suddenly pool on your stomach. Looking down you see a previously unseen slit between the creature's legs, a steady trickle of clear liquid dripping from it. It hisses again; it almost sounds like a laugh. It lowers its lower half and begins to grind the slit against you. Despite your best efforts and the horror you feel, you can't help but feel aroused by what was happening, your length hardening slightly. You gasp in pleasure as the dripping slit passes right across your cock-tip, the slit spreading a little as your tip slips along it, drenching your length in ooze.

Making the laughing hiss again the creature stops and raises itself back up, making you whimper a little. It slowly crawls forward, until eventually it sits on your chest, its slit a few inches from your eyes. You manage to get a good look at it. The inside of the slit was greenish compared to the pitch black creature, and the slime it oozed was clear in color. Without warning it shuffles forward, pressing the slit against your surprised mouth. Slime seeps past your lips, filling your mouth as the creature's slit ground against your lips.
