Billy, His Mom and Sister Allison

“Well that was interesting wasn’t it Billy?” Cheryl remarked on the ride home from Billy’s medical exam.
“Very,” answered Billy “and fun to.”
“Yes, you certainly looked like you were enjoying yourself. It was almost like you wanted to show yourself to the Dr. and her nurse.” Replied Cheryl.
“I did mom, there was something very exciting about it.”
“Maybe you’re an exhibitionist Billy, you know someone who enjoys exposing themselves to others.”
“Well, if that’s what an exhibitionist is then I guess I am one.” Said Billy. “Is it ok if I’m naked around the house some mom?”
“I’m not sure how Al will take that.” Answered Cheryl.
“I doubt she’d care.” Replied Billy
“What makes you think that?” She asked
“Well she catches me naked once in a while and always just seems to laugh or brush it off as if it’s no big deal. She walked in on me in the bathroom a couple of weeks ago and kind of said “sorry” and then giggled a little as she pinched me on the butt.”.
“Oh”, replied Cheryl just a bit surprised “I didn’t know that”
“Yea,” he replied “sometimes it seems like she kind of does it on purpose. She almost walked in on me jerking off a month or so ago.” He added.
“How often do you masturbate Billy?” Asked Cheryl.
“I guess once or twice a day.” He said.
“It’s ok to be naked in front of me all you want Billy and also to masturbate any time you want if I’m around or not.” Answered Cheryl.
“You seemed to like watching and helping me mom.”

This comment caused Cheryl to pause for a moment, but Cheryl was a very rational and straightforward person. She had never really felt there was any big deal about sex and had taken that approach when raising her children. While rarely nude in front of each other, or so Cheryl thought, being in their underwear around each other was common and they had from time to time made little sexual comments and used words such as cock, pussy, fuck and jerking off.

“I did” she eventually replied. “It was really fascinating to watch you pleasure yourself and to “lend a hand!”” She chuckled,
Billy chuckled also.
“Well feel free to “lend a hand” anytime you want mom!” Billy jokingly replied back.
Cheryl glanced over at him and looked him in the eye smiling a really slay smile and said
“Ok, maybe I will. I’m going to be keeping an eye, literally, on how well you keep yourself clean.”
“No problem mom, you can examine me anytime you want.”
“Well thank you young man!”
Which caused them both to laugh a little.

While preparing dinner that night Cheryl thought about what Billy had told her about Allison walking in on Billy naked and thought that maybe it would be a good idea to bring Billy’s exam up over dinner. Her excuse to herself was so that Allison would know what was happening if she saw her examining Billy’s cock. But in actuality it was because she was curious about Allison’s feelings about nudity and sex. There was a part of Cheryl that was a little uneasy about her and Billy’s obvious sexual attraction to each other. But if it pleasured both of them what was the problem she reasoned.

At dinner that night after a little small talk Cheryl decided to change the subject.
“Well Al, Billy had his physical today and it was a rather interesting experience.”
“How so?” Asked Allison.
“Well everything was ok until it was time to examine his genitals.” Cheryl began.
With this Allison laughed and said
“Oh, I bet. Tell me what did you do Billy?”
“I dropped my drawers in front of everyone, including mom. That’s what.”
“Oh…well…so tell me mom did you get a good look at little Billy?” She chuckled.
“Oh did I” Cheryl said playing along. “Only little Billy wasn’t so little. In fact little Billy was rather excited and was standing up for all to see!”
With that Allison turned to Billy and laughing said
“You mean you got a hardon in front of the Dr.?”
“Yes, I did.”
“So tell me mom what happened next. I have to know?” Demanded Allison.
“Well the good, straight laced, mature Dr. Morris gave Billy his hernia and testicle exam and then she moved onto his penis.” Answered Cheryl.
“Oh so she played with your balls then?” Asked Allison, “Did you like that Billy? Did you like having a woman old enough to be your grandmother play with your balls?”
“Yea, it was kind of cool but what really got me off was what happened next.” Billy said.
“And what was that?” Asked Allison
“Then she took hold of my cock and examined it.”
“Well ok” Cheryl interjected, “As you probably know, Allison, Billy is uncircumcised.”
“Oh yea” interjected Allison “I know all about that big floppy foreskin of his and his saggy balls.”
“Well,” continued Cheryl “apparently your brother hasn’t been keeping his foreskin clean enough so long story short I’m going to have to keep a check on him.”
“Well that doesn’t surprise me” replied Allison.
