Masturbate Again.

Still hard after your previous session, you start to stroke your erect dick again, an **** wave of satisfaction flowing through you crank your hand up and down. You feel your dick grow bigger in your hands and pre-cum begins to seep down on to them. With a deep moan you climax again, sending sperm flying across the room. This time you are sure your cock grew bigger. You felt it.

"How odd?"

You also feel a familiar presence in the room with you, but as you look around there is nothing but darkness. The only light entering your room is from the moon.
