Part 1
The living room was pin-drop quiet a long moment while Billy digested everything.
"Again, if you don't want to, you don't have to." Rex said to his stepson.
"No, I do," Billy said, turning to stare out the windows. "I guess it's just a little..."
"Unusual? It is, but you know your mother loves you and would never do anything that was bad for you. Right?"
"I know," Billy nodded, looking at the floor. "What do...?"
"First thing, take a shower. Then put on a pair of underwear and go downstairs to the guest room."
"Is she down there now?"
"She got home from her exercise class a few minutes before you, and said she needed a long shower. The shower in our room is acting up." There was nothing wrong with their shower. The tiny white lie was an expeditious means to get them both downstairs where Helen wanted their first time to happen.
Billy's eyes grew distant. Rex had no doubt the eighteen year old was imagining his huge-breasted mother naked in the shower.
"Um, where are you going to be?" Billy asked.
"Up in my office. I've got enough paperwork to keep me busy most of the night."
Billy nodded, then looked Rex in the eye. "And you're... um, you're okay with this? With her checking me and...?"
Rex smiled. "If I wasn't, we wouldn't be having this conversation."
Billy nodded slowly, thoughtfully. "All right. Guess I better get going."
"I think it will be a wonderful thing for both of you. And as an unnecessary reminder, again, it must stay between the three of us."
"Yeah. Sure. I totally get that."
When Billy stood up, Rex couldn't help but steal a quick glance. Not surprisingly, the always prominent bulge in the front of his stepson's pants was much more noticeable than usual.
He waited until he heard Billy going up the stairs before he pulled out his phone and texted his wife with: "OK."
She responded instantly: "Thank you so much."
He shot back: "You're welcome. Enjoy yourselves."
As he got up from the recliner, Rex heard the shower in the basement go on. He started up the stairs a moment later and heard the shower in Billy's room go on. There were some advantages to having creaky old pipes.
Rex went up to his office and double checked to make sure the door was locked before he sat at the desk and fired up the triple monitor display. All fourteen hidden cameras, remotely controlled high resolution color with audio, were already on and recording. He tested the zoom and focus on each, starting with the one in the upstairs hallway and worked his way to the basement.
There were three cameras in the guest room. While Billy and Helen were asleep last night, he had spent more than four hours getting those cameras hidden and properly aimed. They were directed at the bed from the foot and either side. Their view could be widened to cover the entire room or zoomed in tightly enough to make out the dime he'd laid in the middle of the bed for a test. The only problem was that they were static views that couldn't be panned or tilted.
The dresser cam allowed him a view into the bathroom. The door was open and he could see his wife's silhouette in the shower through the frosted glass door. He couldn't make out specific details, but he could see the outline of her hourglass figure, and in particular her enormous, heavy breasts swaying as she turned under the spray. It was perfect; that would be the first thing Billy saw when he came into the room. Rex watched her until movement in the upstairs hallway caught his eye.
Billy came out of his room wearing nothing but tighty whities. Tighty whities with an obscenely large bulge in front. Any wondering Rex may have had about his stepson's endowment went out the window. That bulge was astonishing.
Billy glanced toward the closed office door and then went down the hallway to the stairs. Rex followed him on the monitors. Billy ducked into the living room and seeing it was empty, headed for the stairs to the basement. The laundry room camera picked him up coming down the steps where again he paused to look around. He went halfway down the hall to the guest room and stopped. He pulled his underpants away from his front and reached inside to rearrange himself, tucking everything down snugly. He took a deep breath and went down the hallway toward the guest room. The door was open.
Rex quickly shut off all the cams except the ones in the guest room so that he would have a dedicated monitor for each of the three views. The camera in a fake fern picked up Billy cautiously leaning into the room and glancing around quickly before his widening eyes locked on the bathroom and the outline of his showering mother.
Rex manipulated the zoom, but without tilt or pan abilities, he couldn't get a close up of the showering mother or her gawking son from their current locations. He watched both of them with growing impatience as her shower went on and on.
Finally, Helen turned off the water and Billy leaned back out into the hallway.
"Um, mom?" He called. "You in there?"
"Come in, honey," she called back.
Looking nervous, Billy took a hesitant step into the bedroom and Rex's eyes widened. If the bulge in the eighteen year old's underpants had been obscene before, now it was almost frightening. With Billy fully in the room, Rex could finally zoom and he did, zeroing in on the bulge. He could clearly see the outline of the incredibly long and fat hose tucked down over the twin lumps of giant balls. His cock was definitely bigger than a couple minutes ago.
"You talked to your stepfather?" Helen asked.
Rex looked at the dresser cam monitor to see Billy's view as Helen opened the shower door but kept herself behind it as she reached for a towel. She closed it again and they both watched her silhouette through the steamy, frosted glass.
"Uh, yeah," Billy said.
"What did he tell you?"
"That, uh, that you want to check my... um... my..." He trailed off.
"Your penis?"
"Yeah."
"Did he say anything else, sweetie?"
"That uh... uh... you might also want to... show me some... things to make sure it works... and so I'll know about girls."
