I was awoken in the morning by a sharp, throbbing pain in my groin. Damn! I thought. I guess it wasn't a dream. I groaned and rolled out of bed. I was surprised to find Anna gone from the bed and nowhere to be found. I had to piss something fierce. I hurried to the bathroom and stood over the toilet. I wasn't sure how easy it would be to pee wearing the chastity device, but I was pleasantly surprised. The plastic had kept me from getting morning wood (even though my body had tried fiercely), and it also forced my penis straight down. I didn't even need to use my hands.
I hoped that Anna was down at the front desk getting my key. In the meantime, I jumped in the shower. As I was toweling off, I heard voices in the kitchenette of our suite. I walked out to find Anna standing at the breakfast bar talking to none other than nurse Aimee.
"Tim," Anna said. "You remember Aimee from yesterday's exam, right? She was just helping me with the issue of your key."
"Hello..." I said, tying the towel around my waist. "Were you able to find it?"
Aimee looked at me apologetically. "That's just the thing. The key is nowhere to be found. Normally they're given to the wife, but it was somehow lost between your exam room and her's."
"What?!" My heart sank. I didn't know if I was more angry or disappointed. I needed to cum!
"Now, I can have another key made from the serial # on your device. Anna, would you please read me the numbers from the bottom of the device?"
Anna crouched in front of me and removed the towel from around my waist. She lifted the device in her hand and read "XSM-2A-3497. Is that some kind of model number?"
"Yes," Aimee replied. "XSM stands for extra small, 2 is the length in inches, and A refers to the girth measurement. The letters increase as the size goes up, like a bra."
Anna's eyes peered up at mine and she had a devious look on her face. "So...do you have a lot of this model?" She asked Aimee mischievously.
"Oh yes, quite a few." I sighed with relief and my ego rebounded a little at Aimee's response. I smirked at Anna. Maybe I wasn't so small after all! But my victory was short-lived as Aimee continued, "We always have a lot left in the office, because we don't need to use them very often." My face dropped in defeat and it was Anna's turn to smirk.
"Oh, really?" Anna faked shock. "I thought my husband always had an average sized cock-er, penis."
"Well, the numbers don't lie." Aimee quickly flipped through the records in her notebook and continued. "In fact, it looks like we only have three of this size in use this week." She stared right at me and grinned as she said it.
"Wow!" Anna exclaimed. "I always knew Tim was one of a kind, but not in this way."
Aimee laughed. "Sometimes we don't have anyone in his size at all. This week it looks like the predominant color this is... blue." She flipped her notebook shut.
I prayed Anna would just let it drop and not follow her curiosity. I lost.
"And what does that mean exactly?" Anna asked.
"Blue is the 'large' size. But we also have a lot of black devices, which is 'extra-large'. And you're in luck; we even have some red ones this week."
I didn't know what she meant by saying my wife was in luck, but it sounded worrying to me.
"What is red for?" Anna couldn't help but ask.
Aimee was all too happy to answer. "Red is for 'oversize'. They fit the opposite end of the spectrum as your husband here." Anna grinned at that.
I was mortified, but at the same time all this talk was turning me on. It was probably because I was still yet to cum from the previous night's festivities with Anna.
"OK," Aimee turned to the door to leave. "I'll get this ordered and it should be here tomorrow."
My heart sunk. A whole day!
"What was all that?!" I exclaimed as soon as Aimee had left.
"What was what?" My wife asked innocently.
"Talking about my size in front of her! And prying about the other guests!"
"Oh, I was just making conversation." She tried to pass it off, but I had seen the glimmer in her eyes when Aimee revealed just how well-endowed everyone else here seemed to be. "Besides, she's a professional. She sees a lot of cocks, so it stands to reason she's fully aware of how small yours is."
"What about the key? I'm dying here!" I slumped onto the couch in disappointment.
"Oh, it's just one more day! Surely you can wait one more day? For me? For this...?" Anna walked over seductively, straddled her knees across my thighs on the couch, and pulled me in for a long kiss. She pulled my hands to her ass, and I kneaded it hungrily. Breaking the kiss, she leaned back and pulled the bottom of her shirt upward and over her head. She flung it aside and shook her hair back from her face.
I gulped hard. She had still just been wearing her bra-less tank top from last night, so now her bare breasts were on full display. They looked incredibly soft and squeezable. She put her hands on my chest, which pushed her ample cleavage together and made her boobs look even more full and round. Her light pink nipples were fully erect and pointing right at my face.
