He was in the college lecture hall wiping off the whiteboards. Mrs. Grayson was head of the astronomy department and was the one who got Drake interested in celestial mechanics.

"I got good news. I've got time on the telescope at Kitt Peak. I could use an assistant." She was trying to prove her theory that there was more than one black hole in the Milky Way Galaxy.

"Sure, I'd love to," Drake replied. "It will be a good experience."

In a few moments, they were checking into a motel in Tucson. They went into the room. Drake was surprised there was only one king-sized bed. She took off her blouse, and Drake stared at her.

"I know you want me. You've been leering at me all semester."

Drake didn't know it was that obvious. She married another professor and had two children, but he wanted her more than anything. The bra came off. Next, his hands were on the tits, and his mouth was sucking on the hard nipples. In a few moments, she was on the bed naked, and he was going between the legs sucking in the pussy lips while continuing to massage her tits. He was moaning because he had never tasted a sweeter pussy, and it was getting sopping wet.

"Please get inside of me. I want to feel it."

He loved that she was begging for it and rammed it in, loving the sloppy cunt.

The alien bounced up and down on his cock, loving the human sex organ. It came in many different sizes; this one was so nice and thick. It also loved how it needed a little rest and was ready for more. Their species only mated once a year and loved how humans could do it almost all the time.

They never left the hotel room. Drake fucked her mouth, making her gag on the thick cock and swallow his cum. She got on her hands and knees, and he went from the pussy to the ass, pounding each one as hard as he could, making both take his cum, and then it was time for rest.

William was on a gurney with a headset on. The alien was amazed at how long the sex organ was; theirs was only three centimeters. He came home from school. His parents were on another archaeology dig. They were gone most of the time, and he had a nanny to look after him. Charlotte was a proper British nanny, and she was in the kitchen.

"Are you hungry?" she asked.

"Yes."

She removed the apron, sat in the kitchen chair, and patted her lap. William got on her lap. Charlotte unbuttoned the blouse, spread open the blouse, and dug the tit out of the bra. William latched on to the nipple, sucking and tasting sweet milk. She unzipped his pants, dug out the cock, and stroked it.

"Maybe you are getting too old to nurse at my tit?"

"Never," William replied and then went back to the tit.

"You are a man now and must feel your first pussy."

"Yes, I want it."

He got off her lap, and she hiked up the long skirt, got on the table, and spread her legs. There weren't any panties.

"Now, get every inch of that beautiful cock inside me."

The alien was making little squeaking sounds. The long thin cock was getting in deeper than anything had gone before. The fifty aliens on the ship were drawing lots to see who got to enjoy the human sex organs next. Every day William came home from school, Charlotte waited for him, letting him suck and drink milk and then ram his cock into her pussy.

There was a scream from the alien as Cole's cock ripped the sex organ open. He was at the city swimming pool because his application to become a lifeguard had been accepted. Dana was in the office and dressed in the red swimsuit that hugged her body, showing off every beautiful curve, a lean body, and fantastic tan.

"Congratulations on becoming a lifeguard," Dana said. She looked at the clipboard. "You got the Saturday and Sunday afternoon shift."

It would be the first time the pool would be open for the year.

"That's fine."

Dana went to the locker and got a pair of trunks. "Here, try these on. They should fit."

Cole went down the hallway, into the bathroom, and put on the trunks. Dana looked him over. "You are so pale, but being out in the sun will give you a tan."

Dana smiled because there was a bulge in the trunks. Cole had a crush on Dana for a couple of years. Her hand went over the hairless chest, down lower, and into the trunks. Cole was moaning as the hand stroked the cock.

"I want this," Dana said.

"Oh, yes," Cole replied and pushed down the trunks. Dana got on his knees and got the entire cock into her mouth. He had never felt so good as her experienced mouth and tongue went all over his cock. Her hand was going up and down on the shaft. His entire body was electric, and it was so very close.

"Do you want me?"

"Oh, yes."

"Then sit in the chair," Dana replied.

His cock got even harder, watching her slowly push down the swimsuit, exposing her beautiful body. Cole moaned loudly as her pussy slid down on his cock. She hardly had any tit, but it didn't matter the pussy was so sweet on his cock.

It wasn't long before he was giving up his cum. Cole stayed until the pool closed and helped Dana close up; then they went to the office, and she rode his cock, taking more of his cum. The human seed was more valuable than any minerals Pluto had.
