On three

John placed his thumbs under his waistband and placed his fingers on the button of his jeans. “How about we drop our pants together?” he suggested. “Say, on three?”

Rachel nodded and she set her fingers likewise. “Ok, on three.”

“One”

“Two”

“WAIT!” She pulled her hands up in a ‘halt’ gesture. “Before we go on, I just want you to know that I really appreciate your help. Also I want you to know that if you try and trick me and you don’t drop on three, I’m going to shout ‘****’ at the top of my lungs!”

John blinked. “Umm. Ok, but I promise I’m not going to trick you.”

“Ok,” She got back into position. “One?”

“Two”

“Three!” With a flip of finger and a push of the wrist, both his jeans hit the floor.

John looked on in awe and wonder at her exposed pussy. Her red pussy hair was not very thick. Her cunt lips pressed together, almost waiting for him to open them.

“You have a hard on?” Rachel brought him out of his trance. His face turned beat red.

“Well, you must admit this is one the most… stimulating science experiments we have ever had.”

She gazed at his erection. “Well, I guess I’m a little turned on too, if that’s what you mean.” She stepped closer and bent down for a better look. “I have to be honest. I have not seen too many. This is like really big, right? All I know is what I read a book in the library it said something like 3 to 5” was the normal, but I got the impression he probably had a real small cock-I mean penis.”

He was just about to brag. He wanted to say, ‘It’s about as big as they… cum,’ but he decided to be honest for the sake of ‘science.’

“I don’t really spend a lot of time looking at other guys. But I have read umm… literature, yeah literature on the subject.”

“You mean porno stories?”

John nodded. “Umm… right. Anyhow, I figure any measurements they list range from above average to freak of nature. I measured myself with a ruler, and I reach nine and five-eighths inches, which seems to be ... competitive."

Rachel smiled and delicately took his member in her fingers. Her slight touch sent ripples of energy into him. John realized she was not giving him a hand job. She just examined it like a specimen in biology class. Still, the touch of a woman was almost enough to have he shoot her in the face right there. She felt the weight of his balls, the texture of his scrotum. She traced the length of his shaft with her fingers. John so wished she would stop teasing him and let him just fuck her like mad.

"What's this?" she asked touching a bead of liquid at his tip.

"Umm, that’s pre-cum, or more scientifically pre-ejaculate," John admits to her, "Your touch is very, VERY stimulating."

"So this is a stage in male arousal?" she asked.

"Yes, I think it is supposed to moisten and lubricate the path the semen is going to take."

"Does this mean you are about to cum? I mean, ejaculate?"

John shook his head. "Not this soon, but it is a step in that direction."
