In a few days, strolling about the neighborhood, I met Nina, the girl Natasha had swung the stick between my and her legs at the nude beach.

"Hi," she smiled cunningly, "How are you?"

"Fine, and you?"

"Me too, I know your name's Pete and mine is Nina."

"I remember your name very well," I said.

The girl being very pretty and cute, I at once felt a great liking for her. To be true I had felt that feeling first there on the beach, when she stood proudly over me, looking at me clutching my balls and envying her her body without those dangling, vulnerable organs. And now meeting her was a pleasant surprise. We started walking together along the street, talking of different things. And then she asked:

"It was such a fun when you kicked that man's balls. You like kicking guys in the balls?"

"Not too much. I'm a guy myself. I think it's more fun and joy for girls who have no balls themselves to kick boys. If I were a girl I would certainly like doing so. But sometimes I imagine myself a girl and then I feel like kicking guys in the balls. There on the beach I was in a girl's dress and it was easy for me to pretend a girl. And sometimes I just hide my balls between my thighs..."

"How's that?"

"Oh, I can show you some time.., and you, do you like kicking boys in the crotch?"

"Actually I didn't have many a chance to do so. I remember, when I was younger, I saw two boys fighting and they agreed not to kick each other in the balls. I wondered why. And in a few days I slapped my cousin's groin to see what would happen. And I was surprised! I hadn't known that boys are so weak down there. Just a light slap and my cousin became such a baby-cry. Then I witnessed several boys being hit down there. All the time they were so helpless, holding their balls and crying. And then there on the beach, when the stick flew up between our legs and I saw you down on the ground, I was so happy I didn't have balls. I just can't imagine what it feels to be hit in the balls. Sometimes I wish I could become a boy for a couple of minutes to get kicked in the nuts to know the kind of pain you guys feel and then straight away become a girl again."

"Why," I said, "you can use your imagination, like I do, and imagine yourself a boy with balls and I'll imagine myself a girl. Then I'll try to hurt your balls and you'll act like a boy. So, wanna try?"

"But how can we do that?" Nina asked.

"It's very easy. There's nobody at my home at the moment. Let's go over there and I'll show you something."

Pretty soon we were in my room. I fetched two ping-pong balls and put them in a sock.

"Take it," I handed the sock to Nina. "It's gonna be your scrotum with the testicles inside. Just put it beneath your pants."

She inserted the sock with the balls under the crotch of her tight pants, looked down at her "newly made package", cupped the "testicles" with her hand and giggled:

"Oh, these are my precious balls, please don't kick them."

She looked so funny with those ping-pong balls tightly pressed to her flat groin inside her pants. Then there came my turn to make some pretending.

"Okay," I said, "you've already seen me naked, so there's no shame for me."

In a few seconds I stood completely naked before Nina.

"Look," I said as I took my balls and penis in my hand, "now they will disappear."

And I hid my genitals between my thighs, as Natasha had taught me, and pressed my legs tight.

"You see, I've no balls now, my groin is so smooth," I rubbed my pubic bone, "and you've got balls in your pants. Now I'll make you envy me."

I grasped a ruler from the table beside me and gave a sudden and sharp slap to the ping-pong balls in her pants. Nina just chuckled. I hit her "balls" with the ruler again and she started laughing.

"Why are you laughing?" I inquired. "Do you know what pain such a hit with a ruler gives to the balls"

"No, I don't," she smiled. "How can I know if I've no balls."

"You do have balls," I pointed at her groin.

"But they are not real," she protested, "and I can't feel anything when you hit them."

"Don't you forget that we're using our imagination now. I'm a girl and  you're a boy. Boys do have balls."

"Do you think it that easy to believe I have real balls and not these ping-pong things? I just don't know how I should react to those hits of yours."

"Alright, I'll display it to you, just take those balls out of your pants."

When the sock with the balls fell onto the floor I spread my legs a little bit, letting my balls take their usual position.

"Just feel the force," I said and very lightly slapped her flat groin with the ruler, "Is there any pain?"

"Not a bit," she shook her head.

"And now just give the same slap to my balls, I mean as hard as I did to your own groin," I said and handed the ruler over to her. She obeyed and though her slap was as light as mine, it gave me quite a pain that I felt not only in my balls but high in my stomach.

"Ouch," I exclaimed and grasped my nuts.

But the hit being very light, the pain died out pretty soon.

"Now give me the ruler back," I demanded and then slapped her groin a bit harder.

"What do you feel?" I asked.

"Just a light slap," Nina replied.

"Just hit my balls with the same force," and I returned the ruler to her.

Her next slap made me double up, clutching my testicles and giving out a long groan: "Oooooooh!"

My reaction made Nina laugh heartily:

"Just a light slap and you look so funny."

"Not funny for me," I muttered, still doubled over, "it really hurts"

"Then let me hit your balls harder!"

"No, oh, no," I straighten up, protecting my balls with my both hands, "if you use a bit more force I won't be able imagine I'm a girl without balls. I'll just be a helpless boy with awfully aching balls. But now I want you to be a boy with balls. So get those balls back in your pants," I pointed at the "sock-scrotum" lying by her feet.

When the ping-pong balls were again underneath Nina's pants and my balls hidden between my legs, I took the ruler from her hand.

"See now," I gave a series of rapid, sharp slaps to my "testicleless" flat groin.

"No pain at all," I grinned, "and now we'll see your reaction," and I suddenly hit the tennis balls in her pants with the ruler.

"Oooooh," Nina gave out a loud cry and grasped the fake testicles." My balls, my balls, they hurt like hell!"

No sooner had she taken her hands off her groin as I gave one more slap.

"Oooooh," she again seized her "balls", "Oh please don't do that again, my balls so hurt. You are so lucky, Pete, you don't have balls and you don't know anything about the pain I feel now."

Nina doubled herself up.

"Those damn balls," she went on clutching her "package". Why do I have them? How I wish I was a girl like you, Pete."

She straightened herself up again and holding the "damn testicles" with one hand she touched my flat groin with the other.

"Oh, it's so nice not to have balls," she looked straight at my eyes, "there's nothing to squeeze at your groin."

"And I can squeeze your balls," I said and in a second her "balls" were in my hand.

"Pete, please don't squeeze them or I'll die from the pain,"

I started squeezing the ping-pong balls", shouting:

"Do they hurt?"

"Pete, do stop, do stop," she was imitating a great pain, "They hurt! Just let me go, oh so much pain in my balls! Just let them alone!"

I released her "package" to see her kneeing down, holding her crotch with both her hands. "Oh my poor balls, my poor balls."

And all of a sudden she burst with laughter.

"Why do you laugh?" I stared at her, astounded.

"Oh, Pete, I just can't be pretending too long. And I can't imagine the pain, just can't," she said and extracted the sock with the ping-pong balls from her pants.

"Well," I said, my balls still hidden from her eye, "try to remember the worst pain you ever had in your life."

She reflected for a while and then said:

"Once a goose pecked me at my shin, the pain was so bad that I thought I would die. Has a goose ever pecked you?"

"Yeah," I nodded.

"Is the pain the same, I mean, when your balls are hit?"

"Of course not, nothing can be compared with the pain when the balls hit, none of goose pecks. But if a goose pecked my balls, I would surely die from the pain."

"Really?" she made such a funny grimace that made me give a laugh and my balls jumped out from their hide. Another second and my testicles were in Nina's hand.

"You say you'll die from a peck at your balls and what about a pinch," and all of a sudden she pinched my right testicle.

I think that a pinch to the testicles possesses the highest pain coefficient. A light slap to the balls gives rather a light aching, a hard kick gives a hard pain, and the lightest pinch to a man's ball gives him such a suffering... And so I was lying there on the floor, my right testicle on fire and Nina standing over me, convulsing with the intrepid laughter. Then she picked up the ruler and started slapping her groin with it.

"Look, Pete, I have no balls at all," she laughed and gave one more series of slaps to her flat groin, then took the sock with the tennis balls from the floor and started slapping the imaginary scrotum with the ruler before my eyes.

I felt so miserable, clutching my searing sack. I remembered the beach, that stick that Natasha swung up between our legs. That stick that showed how different were our bodies - Nina's and mine. I remembered my mad envy, my mad envy when I was on the ground, greedily staring at her spread wide legs and the cute slit between them, my agonizing envy as I was clutching those things between my legs, the same things that Nina was laughing at now. The same things in my hands, the same pain, the same envy. But now there was one thing that really consoled me. I saw that Nina felt great, great because she was a girl. And I wanted her to feel great. Very great. Extremely great. For I liked her, really liked. Maybe I was falling in love with her. My first love in my life. The first real love. For when you love someone for real you wish them to be happy, to feel great, even if it costs you suffering. And all my pain was making that girl feel great, and I wanted her to feel even greater, I wanted that stick again fly up between our legs, smashing my balls and filling her with the feeling of proud of not having balls, proud of her smooth groin, proud of being a girl. I wished Natasha was beside us with a stick in her hand. And I was falling in love more and more as I was looking at Nina, who kept on laughing at me, at me whom a light pinch made so helpless. And I was happy, happy to make her so great, great without balls between her legs. It was real love and real pussy envy...
