You lean up against the tiled wall, preparing to spring into action. Taking the pose of a downtown thug, you wait for the mouse to finish. The scent he is giving off causes an erotic reaction. His scent, containing a musk and sweat and a sweet smell of recent sex, you guess that he is prime for the picking. Puzzling over what to do with him, you thoughts are cut when the toilet flushes and the door creaks open. The little mouse squeaks with complete fear of you standing there. You stand tall, dwarfing him both muscle and mass. He appear to be only three feet tall, with little to no muscle, but a very large bulge emitting from his trousers. He starts to back up, bumping into a wall, his eyes quiver and his breath is at the a quickened pace. You can even hear his small heartbeat, the increase in adrenaline will make for even more pleasure. Even though he wears pants, you decide to go natural, as clothing is optional. He looks up to your face, peering deeply into your deep purple eyes. His gaze travels down, pausing slightly on your lovely breasts, but ending and not moving from your massive balls and sheath. You can smell his sexual arousal, and that causes you to become aroused as well. With a twitch and muscle pull, your sheath squirms and lets loose your large, shiny black dick. It is still flaccid, but even then it is a good four feet in length and a thick foot in diameter, already big enough to engulf smaller furries.The color, as said, is a sickly black with a shiny coat of natural lube created by your body. The mouse is not moving, he is fixated on your member. With a chuckle, you take your handful of cock and start rubbing it from bottom to top. Not more than a minute, and the blood rushes in and fills it to is full potential. At a massive eight feet and two and half foot thickness. Your hefty cock is completely smooth, aside form a massive knot at the base and three fleshy rings in the middle, ending in a pointed tip. The mouse suddenly jolts stiff. He is in a paralyzed state, in complete shock of your size and girth. You feel some liquid running down your inner thigh, realizing that you are starting to get horny as well. You lick your lips with a moist black tongue, teasing the poor mouse.
You start to move towards him, but he squeals and cowers in the corner, arms raised defensively. Even though he is in a near death situation, with a primal fear driving his actions, you can see his bulge starting to make a wet spot in his pants. You smirk, he is enjoying the sight of your breeder. You take a single step, closing the space between you two. He is whimper, and with a quick clawed movement, you rip his trousers free. He screams in absolute shock, letting his natural form take over. He has the standard sized balls for a rodent, with a dick that comes in around eight inches. He is already releasing pre, showing his hormones and arousal. He looks up to you, a pathetic but sorrowful look in his eyes.
"Please..." He begs. "Don't hurt me. I have so much to live for!"
You pause in your approach, feeling a slight ping of pity for the small innocent. You realize that your instincts have taken over and drove you into this position. But you are still horny, and making that go away will not be easy. You could just finish him now and deal with your arousal; or you could wait and work something out.
