Jack strode confidently to the front door. He opened it only enough for him to squeeze though, and then shut it. Anyone else would have been struck with a problem right about now: How to lock the door, and prevent intruders, without a key? Sure, one could carry a key, but, being invisible, one would not have a clue what to do with it without pockets. So, a few weeks ago, Jack had replaced his front door locks with biometric locks. There was a fingerprint scanner, which accepted only the fingerprints of Jack and his family and friends, and a spoken password which responded only to Jack's voice. As an added measure, there was a ten-digit keypad which accepted a numerical code, and a standard keyhole. For a standard key. You know, in case the plumber needed to get in, and no one was home.
So Jack's house was secure, and no one could see his nudity. All in all, a good start to the day for our hero.
Jack breathed in the brisk morning air. He felt it on his skin. He didn't mind the cold, in fact he liked it. He was just glad no one could see his rather large penis shrink at the temperature to a more modest size. He gave his flaccid member a tug or two, played with it a little, to get the blood moving. It responded rather quickly. Soon Jack had a raging erection, and nothing sexy to look at.
I should go find some pretty girls,
Jack thought. Go ahead, Jack. You go do that.
There were not too many people out this early in the morning.
Except runners,
Jack realized, smiling, as a runner ran up.
Perfect.
She was a girl a few years older than Jack, and incredibly fit.
Why is it that these girls always wear the tiniest outfits in this weather?
Jack then considered his own lack of attire and shrugged. The girl was dressed only in the briefest red sports bra and shorts set. Her body was magnificent. Her breasts were huge, and nearly spilled over her top. Her legs were long and toned. She had reddish brown hair down to her shoulders, and brown eyes the color of caramel. She was gorgeous. Jack gave his penis a rub as he watched her. Then he got an idea. He waited until she passed him, and then he ran after her. He loved watching how her ass moved. Occasionally he would run up to her side to watch her breasts, and then fall back into position behind her. Jack ran a lot, so this was easy. He wasn't even breathing hard, he noticed.
After about three miles, the girl slowed down and reached what was obviously her home. She unlocked the door, and Jack made ready to pounce in through the door. Luckily, it worked.
These visible people always just swing their doors wide open. Invite the whole town in, why don't you?
