My Cousin Used Me As Her Anatomy Model

I suppose a lot of people have a "playing doctor" story from their youth. My two female cousins played doctor with me, or more accurately, one used me as an anatomy lesson to teach the other. They came to visit us for several days every year during summer vacation. Jessica was a couple years older than her sister Amy. I was a few months older than Jessica, but she was more assertive and less naive than I was. Jessica actually grew up to be a doctor, but in those days I thought of her as a bossy, bitchy know-it-all. When adults weren't around, she never called me by my name; she callled me "Pee-wee" after Pee-wee Herman whom she thought I resembled (I didn't).

Most of the time during their visits they ignored me, but one day Amy wanted to see the little addition in the back of our house that my college age sister was living in over the summer (she was gone at that time on a trip). An extra key was hidden near the house, so I got it and let us all inside. We'd been swimming earlier in the day, and Jessica and Amy were still wearing their bikinis. As I showed them around the house, I couldn't keep my eyes off of Jessica's developing curves which had appeared since I'd seen her the summer before. Although I tried to fight it, I got excited and was pitching a tent in my swim trunks. Amy pointed at me and said, "Look! It's pushing his shorts out!"

Jessica said, calmly and clinically, "That happens to boys sometimes. We're the cause of it. Girls can make boys do that without even trying. Boys can't help it."

Jessica looked around the room and saw an artist's paintbrush that belonged to my sister. She got it and said, "This will make a good pointer. Ok, Pee-wee, pull down your shorts!"

I didn't even like Jessica, but I was curious and aroused, so I did what she said.

She pointed at my erection with the handle of the brush and said, "Now, Amy, you probably know that this is called a penis. DO NOT, I REPEAT, DO NOT let a boy stick this in you. You know, in your vagina, your pussy. They'll try, but don't let them. It can make girls pregnant."

"How?" Amy asked.

"It shoots out stuff that's not pee. White stuff called sperm."

"What's that little drop at the end of it, Jess? Is he going to shoot it now?"

Jessica swiped the drop off the tip of my cock with the bristle end of the brush and said,"No, he's not going to shoot anything." She glared at me and said, "He better not, anyway, if he knows what's good for him. But like I said, Amy, DO NOT let one of these inside you."

Amy, who seemed both fascinated and a little repelled, said, "Don't worry, I won't!"

"Now, these are his testicles and they're inside his scrotum--that's what people call the balls and the sack. The testicles are very tender. You can hurt a boy if you're not careful. Watch."

Then Jessica tapped one of my balls with the stick end of the paintbrush, snapping back her wrist slightly as she did it. I winced and my knees buckled a little.

"See! Just that little bit hurt him." Jessica tapped the other one, and went back and forth to each one, tapping until I pushed my legs together and said, "Jessica, stop it!"

"Oh, it didn't hurt that bad, you big baby. But you see what I mean, Amy, so if you have to, you can hurt a guy, but only if you have to."

Amy nodded.

Jessica looked around the room again. She picked my up my sister's blow dryer from a table and plugged it in an outlet close to us.

"Let me show you something, Amy."

Jessica turned the heat setting on and pointed the blow dryer at my balls. She handed it to Amy and said, "Keep holding it at this distance, and watch what happens to his sack. Go ahead, Amy, I want you to understand that a boy is nothing awesome. In fact they're kind of funny."

The dryer's heat was comfortable at first and before long I felt my balls relaxing.

"They're getting lower!" squealed Amy.

"Yeah," Jessica said. "I read in a book that heat makes a guy's testicles hang lower. Isn't that funny?"

When she saw the effect the heat was having, Amy couldn't resist holding the dryer closer and closer, but I didn't complain. When my balls were about to fry and hanging as low as they possibly could, Jessica took the dryer from Amy and turned it off.

"Ok, now I'll show you something else!"

Jessica hurried to the refrigerator and got some ice cubes. She wrapped them in paper towels and pressed them hard against my balls. The cold was so intense I stepped away. She put her palm on my chest and lightly pushed me until my back was against a wall. "Now hold still, Pee-wee," she ordered. She pressed the ice against my balls again.

I could feel my sack drawing up, a lot faster than it had dropped. "Damn it, it's too cold," I said.

"Shut up. You'll be fine. You're such a whiner," Jessica said.

I kept as still as I could. When Jessica removed the ice, my balls were pale blue and tight against me and my cock had shriveled along with them.

Amy's eyes widened and she said, "They shrunk up! And his thing--I mean his penis shrunk too."

Jessica smirked and said, "Yeah. I guess 'Pee-wee' really is a good name for him. Amy, I just want you to remember this day when you see some boy acting like he's a super stud.......but this is boring. Let's go back to the pool for another swim."

That was the end of Jessica's anatomy lesson. I kind of hinted that I wouldn't mind if she used me as her anatomy model again, but she said, "Don't even think about it, you little pervert."
