At her apartment building

Milly chose the forty year old John, a big and muscular repairman and her next door neighbour.

Deciding to check on him, Milly activated her powers and turned invisible. She passed through the wall separating his and her apartments. Upon entering, she heard the shower was on.

"Lucky me!" she thought, gears turning in her mind on how to humiliate him.

She entered the bathroom through a wall and then passed through the shower door. Milly could see her neighbour in all his glory. What immediately came into view, now almost at the level of her face, was his 5 inch cock. Not that huge, but it was an okay size for being flaccid. Milly grinned. And of course, John could not see her or feel her presence.

She exited the apartment, passing through a bunch of walls. She was now outside in the hallway where her, John's, and another apartment intersected.

She rang John's doorbell.

Nothing happened.

She rang again.

This time, the door started unlocking and opening. On the other side of the door was John, wearing nothing but a towel on his waist.

John looked around but could not hear or see anybody.

Milly, who deduced that John will likely just go back inside now that he saw nobody was there, pulled out a tiny piece of rock from the pocket of her tight shorts. She then threw it down the stairs of building. As it left her possession, the tiny piece turned visible and could be heard again if it hit something. The rock tumbled down the stairs.

John heard this and stepped out into the hallway in just his towel.

"Hello?" he said.

He went to the railings of the stairs and put his hands on them so he could lean and look down if anybody was there. He saw nobody.

Suddenly, John's towel was snatched away from his waist and pulled back into his apartment by an invisible ****. In an instant, the door of his apartment also closed and locked itself. John was now locked out of his apartment, completely naked.

He quickly cupped his crotch with both hands to cover himself. He could not believe what happened. If he ever wanted to go back into his apartment, he would need help, and help would mean he'd be seen naked, most likely by a female student way younger than him as they occupied the building in high numbers.

Thinking about the situation, both of his ass cheeks were grabbed firmly from behind. He turned around, but nobody was there in the hallway with him. Him turning around and seeing nobody caused his hands to move away from his crotch.

Seizing their opportunity, two ghostly hands now grabbed hold of his exposed dick. John was paralyzed by the sensation, but despite that, he was now standing with his hips thrust forward. He felt as if his cock was being stroked by two soft and gentle hands. John was moaning as he lost himself in pleasure. His cock was fully hard, now being 6 and a half inches long. He was leaking precum.

After a minute or two of the mysterious phantom stroking, the sensation stopped.

"Hi, I heard moaning and stepped out to see what was happening!" said a female voice behind John.

John who was shocked, and suddenly snapped out from his previous daze, turned around and saw the beautiful Milly.

"Oh my God! You pervert!" said Milly, mouth now wide open, hands on the side of her face, and eyes fixated on John's fully erect glistening cock which he forgot to cover.

"I'm going to call the police, you sicko! You're here in the middle of the hallway, in a building full of freshmen girls, jerking off!" Milly yelled at him, his hands now back on his crotch.

"Please no! Quiet down!" John pleaded, "I was locked out of my apartment and just want to get back in!"

"Trying to get back in... by cumming in the hallway?" asked Milly with an eyebrow raised.

"Uhhh... this... just kinda happend" tried John to explain but couldn't, and a bit shocked that this young girl just said the word "cumming" to him.

"From where I'm standing, it looks like you were trying to enjoy yourself out in the open, like a pervert" she said, "and you enjoyed it quite a bit, seeing as your cock is in that state."

John was lost, fully beaten by this college girl who was more than 20 years younger than him.

"I'm calling the cops" she stated, turning around to walk back to her apartment.

"No, no, no, please don't!" he pleaded again, "I don't want to go to prison! I'll do anything you want, just please don't call!"

"Anything?" asked Milly, now with a huge smile on her face.

"Yes... anything" reaffirmed John.

"Then... drop your hands and keep them at your side until I say you can cover" ordered Milly, "I want to see it again."

John complied. She was staring at his cock again. It was still fully hard. Arguing and being verbally beaten by his beautiful blonde Goddess of a neighbour did very little in relieving John's erection.

"Good, now come inside" guided Milly to her apartment, "I'll decide on what do with you."

John complied once more, following Milly's big wiggling ass inside, his erection not subsiding any time soon.

She played him like a fiddle.
