I stepped out of the shower and wrapped a towel around my waist. I had just returned earlier from a bike ride, and had taken a long shower to ease my aching muscles. I looked at myself in the mirror, and gave myself a once over. I was six feet tall, black hair and pretty well-built if I do say so myself. My one insecurity...well, it was tucked away under my towel. I wasn't going to worry about my below-average dick now after a good workout.
I fumbled around the sink for my glasses, but I couldn't find them. On top of that, I thought that I had brought in some fresh clothes to change into. Maybe I had forgotten? I could hear my wife Emma in the living room speaking to someone, probably on her phone. I cracked the door to the bathroom.
"Hey Emma, have you seen my glasses anywhere?" I called out.
"Hey babe! I think I can see them in here, right on the end table." She replied back.
I stumbled out to the living room, still wrapped in only my towel, and immediately noticed through my slightly blurred vision that there was someone else sitting on the couch with her.
"Hey Jake, it's great to see you! Wow, you are looking great, why don't you walk around like this more often?" A familiar voice giggled.
As she laughed, I recognized the voice of Emma's best friend Charlotte. I grabbed my glasses from the table, and Charlotte came into view. She was about 5'10, with dark brown hair, pale skin, and perfect DD-cup breasts that I had spent more than a few nights fantasizing about. My wife Emma sat next to her, a gorgeous 5'6 blonde woman with perky B-cup tits and a great ass.
"How was your bike ride, honey?" Emma asked. "It looks like you got a good workout in."
"I did! I went for about 15 miles. I'm going to go grab a drink I think, you two want anything?" I replied.
They both said that they were fine, so I walked through the kitchen and drank a quick glass of water. Emma hadn't told me that Charlotte was going to be over today, which seemed odd.
As I walked back into the living room, Emma stopped me.
"Hey, could you come over here for a second? Charlotte and I had a question for you."
As I walked in front of the couch, Emma stood up and walked behind me.
"What's that tattoo on your back, Jake?" Charlotte asked politely.
"Oh yeah, it's just a-" I was cut off suddenly as I turned show her, because I had suddenly felt a cold breeze hit my nether regions as my towel was sharply yanked away.
Emma had grabbed my towel as I turned around, and Charlotte was staring straight at my ass! I made a grab for the towel with one hand desperately covering my junk, but Emma quickly threw it to Charlotte, and she promptly sat on it to keep it out of my reach. I looked at Emma, flushing beet red and fixing her with a glare.
"What the hell did you do that for!?" I asked. "Give me my towel back!"
"Charlotte here also had heard a rumor about guys who ride bikes, and I knew that you'd be happy to help her out. She told me that men who ride their bikes place a lot of pressure on their genital region, and it can cause shrinkage, sometimes permanent." Emma replied with a mischievous smile. "I knew after some of our conversations you'd be willing to show her that it doesn't impact real men like that."
"Plus, you've already got a great ass." Charlotte added. "Let me see the front now!"
My hands were clamped firmly to my genitals, blocking them from view. Emma and I had talked about those secret fantasies in confidence...she wouldn't force me into this without discussing beforehand, would she?
"I didn't sign up for this!" I protested.
"It's fine, we're all friends here. Besides, Emma here has told me all about you already. No secrets between friends, right? Go ahead and show me." Charlotte had smirk on her face as I turned to face her.
I gulped. I knew that my bike ride had left my already less-than-impressive member even more shrunken than usual. But before I could respond, Emma grabbed my hands and yanked them forcefully away from my groin and behind my back, exposing me to Charlotte. Piercing laughter filled the room, as both Charlotte and Emma cackled gleefully at my penis. The shaft of my penis had completely retreated into my body, leaving only the small head poking out from my groin. My balls had tightened up against my body, appearing shriveled up and tinier than usual as well.
"Holy shit, Emma! I know you said he had a small cock but that's ridiculous! Is that from the exercise or is he always that tiny?" Charlotte managed to get out between her fits of laughter.
"He's always pretty small, but I do think he's shrunken a bit more than usual. I was wondering if the hot shower would help, but apparently not!" Emma laughed with her friend.
My face flushed even further, but for some reason I couldn't or wouldn't pull my hands back from behind my back to cover myself.
