On Thursday I received great news. I had been awarded a fifteen thousand dollar grant to continue my research. Since I was on a full scholarship this was basically free money. I called Tracy to tell her my good news. She was happy for me then said.
"We should do some shopping, there are some things I want you to buy."
In my euphoric haze from the grant news I replied.
"When and where?"
"How about Friday, pick me up around 7 for dinner."
I made reservations at a swanky restaurant and pulled into her driveway to pick her up.
She came out wearing a slinky black dress with a plunging neckline that showed off her assets in a most complimentary way. We ate and exchanged small talk over dinner.
Back in my car after dinner she directed me to an adult superstore. I was very nervous as we entered the store. A young girl greeted us and asked if she could be of any assistance.She had long black hair with a streak of baby blue running through it. Short black skirt and loose white tank top. Her large breasts were very visible as she wore no bra and her nipples were prominent against the fabric of her top. Tracy told her we were looking for a beginners strap on. The clerk explained that they had two types, one that required a harness and a double ended one that included a vibrator so both parties could experience the event. I found myself getting hard as Tracy handled the various devices. She decided on both an insertable with a business end that looked enormous but was probably only five inches and one with a harness. She told the clerk that she would be trying it out tonight on me. I blushed with extreme embarrassment. We went around the store and looked at the various toys and devices.
Tracy picked up a spiked penis cage. Each spike was threaded with a small hex head so it could be tighter if desired.
"What do you think of this? She asked.
"Diabolical." I replied, "Could hurt a lot."
"That's the point." She put it in her shopping basket as we continued around the store.
We walked with the clerk into the BDSM section. Lots of crops, floggers and paddles.
"I have a nice collection of impact toys," Tracy remarked. She picked up a curvy wooden set of two pieces.
"What is this?" Tracy asked the clerk.
"That is a humbler" The clerk replied. "You have your boy kneel down. This closes around his balls and he can no longer stand up without serious damage to his balls.'
"Looks interesting, can we try it out?" Tracy asked.
"Here?" II replied incredulously.
"Sure, there is a party room in the back." The clerk replied. The clerk led us to a door in the back of the store. It opened up into a large room. There was a large bed in the room, A few leather chairs and soft carpeting.
"Take off your clothes." Tracy commanded.
Reluctantly I removed my shirt, undid my belt and took down my pants.
"Underwear also."
I kicked off my shoes and removed my boxers. I was mortified and embarrassed as I stood naked in front of the two girls. My cock was at half mast as I was very nervous to be naked in the store.
"What happened to his hair?" the clerk asked.
"I had him waxed." Tracy replied.
"He looks like a little boy except for his large equipment."
"I like my boys sans hair."
"Let me show you how to use this." the clerk replied. "Kneel down here."
I knelt and the two women squatted behind me. Tracy grabbed my scrotum sack and stretched it back. The clerk maneuvered the humbler so that it entrapped my balls. They each tightened one of the wing nuts and the two arms pressed against my thighs. My balls were sticking out tight behind me as they examined their handiwork.
Tracy reached down and slapped my balls with her hand. Although it wasn't the hardest slap I collapsed in extreme pain as my balls had no escape from her hand. She had struck my balls before but when she did my sack was loose and the balls could recoil away. I groaned in pain and tried without success to stand.
"It looks great, we'll take it."
"I'm getting horny." the clerk replied. "Is he very good with his tongue?"
"Very, do you want to try him out?"
The clerk walked over to a leather chair and sat down. She lifted her skirt pulled off her panties and spread her legs.
