It had been a few days since Samantha had returned from a mysterious five week vacation to Mexico with her grandmother. Aaron was looking forward to seeing the cute teen again. He wouldn’t admit it to himself, but he had a crush on the girl. Her bubbly personality, long blonde hair and cute face had caused her to become Aaron’s number one jerk off fantasy. He knew he jerked off to the teen frequently, but he didn’t realize how easy it would be for the lure of those fantasies to tempt him. He had no idea of what was soon to happen, but he was about to be exposed to more temptation than he could have possibly imagined.

“Aaron’s here!” came Samantha’s cry when James let him in.

Aaron heard the patter of quick footsteps from Samantha’s room, but they stopped suddenly when Mandy called out. “Wait! You agreed that we got to warn him first.”

Aaron heard a loud sigh from the teen who was still out of sight, “Oh yeah, that’s right.”

“Warn me about what?” Aaron inquired.

“So, you know that mysterious trip, well my Mom did take Sam around Mexico for three weeks.”

“But she was gone for five weeks.”

“I’m getting to that, the other two weeks were devoted to consultations with a plastic surgeon and recovery.”

“Plastic surgery, but why?”

Another cry came from Samantha’s room, “Come on Mom! You’re dragging this out. I got a boob job while I was out of country; I want to show you!”

“Seems my underage surgery recipient is getting impatient; hold onto your eyeballs Aaron!”

Samantha squealed with glee and came bouncing out of her room. Her tee shirt was stretched to the point of there being horizontal crinkles between her two boobs. Aaron’s eyes were wide as saucers as he tried to drink in all of Samantha’s new bombshell body with long stare, “What the?”

“Yeah, I agreed to 350-360cc max, which would have added quite a bit of size, but while they were operating, the nurse thought she looked better the more they filled the implants and she ended up with 475cc of saline in each one!” Mandy explained.

“Wow! Well, if Samantha is happy with the results, I’m not going to complain,” Aaron stated as he continued to stare.

“Come here!” Samantha instructed. “You need a hug; I haven’t gotten to hug you in a month and a half!” Aaron froze as he felt the two surprisingly soft mounds pressing into him. The sensation made him instantly hard, and for the first time he realized how intense his attraction to Samantha was. It was doubly troubling now that the teen’s developing body had been augmented with surgery designed to turn her sex appeal up to eleven!

Samantha giggled when she looked down at Aaron’s crotch and saw his obvious erection. “Well Mom, I can’t embarrass Aaron if I show him the full effects of the surgery by making him hard.” Samantha giggled again, “He’s already hard. Can I take my top off and show him? Can I? Can I? Please, Please, Please!”

“Oh go ahead,” Mandy gave in.

“Wait, are you sure this is a good idea?” James objected.

“She didn’t have close to a thousand cc of surgical enhancement to keep them covered up. Besides, you got to see a personal post operation reveal. On top of everything else, if I tell her no, she’ll just flash Aaron sometime when my back is turned. I might as well let her get it out of her system while I’m here to chaperon.”

“I’m hurt James,” Samantha informed her step father as her shirt came over her head. “Don’t you want to get another look too? I can’t believe you tried to get Mom to rescind her permission for me to take my top off!”

“Well, if you’re going to get topless, I am going to look, but it is kind of weird the way you’re eager to get half naked for two men who are twice your age.”

“Mom’s right, I love showing my new boobs off! I think they look so beautiful, and I want to share that beauty with you two.” While she was saying this she unhooked the sturdy latch on the back of her bra and held the cups in place. Without saying a word she looked back and forth between Aaron and James. When both men nodded, she let the bra fall away to reveal her huge breasts.

Aaron just stammered, “W-w-w-wow!” as he drank in the sight of the topless teen. “They look so natural, I was kind of worried when your mom was describing how big the implants were, but if someone were to tell me that you were just a busty teen, I would never suspect.” The hard on which sprang up instantly when Samantha had hugged him throbbed urgently in Aaron’s pants as he couldn’t take his eyes off her bare breasts.

“They are mighty impressive,” James agreed. “Sorry Samantha, I was wrong to try to keep you from getting them out again.”

“I’ll show them to either of you any time you want.”

“Whoa there young lady,” Mandy interrupted. “James is getting a second post surgery reveal because Aaron is here, but you’re going to have to be content showing them off in tight or low cut clothing most of the time. Just because you want everyone to see how you look topless now doesn’t mean you get to wander around that way whenever you want. Show the guys a few different angles then get dressed again.”

Samantha was torn between excitement at showing the guys different views, left side, right side, and three quarters contrasting with the disappointment of needing to get dressed again soon. While Samantha was showing off her new body, Aaron made a comment about one of the things that made them look natural was that her nipples were proportional to the size of her boobs.

“I felt like I was all nip before my surgery. I was sold almost immediately when Grandma asked if I would be interested in getting a boob job!”

“Oh, you would have grown into them; you’re still a developing teen you know,” Mandy assured her daughter. “Anyway, time to put your clothes back on. I’m sure you would keep posing, and the guys would sit here staring all night if I let you stay topless.”

Given the order to cover up, Samantha pouted a bit and asked, “Do I have to put my bra back on too?”

“I guess not.”

“Yippee!”

Returning from a bathroom break, Mandy asked, “Notice anything different?”

Everyone did a double take as Mandy’s shirt was stretched out improbably, and Samantha was the first one to speak, “OMG Mom, did you stuff my bra with socks?”

“Yeah, how’s it look?”

“Neither of the guys said anything.” Mandy guessed Aaron wouldn’t say anything too complimentary in front of James, and James had always said he didn’t particularly care for larger breasts.

“Oh Mom, you’re lopsided. We can do better than that! Let’s go to the kitchen.”

“The kitchen?”

“Yeah, you use rice and sandwich bags to make realistic sizers to fill up a bra. Everyone knows that.”

“Well, maybe everyone who has consulted with a plastic surgeon knows that, but I didn’t.”

“Mom, do you want my help or not?”

Mandy grinned girlishly, “Yeah, I want your help.”

From the kitchen the guys heard, “How much rice are you using Samantha?”

“Two cups in each bag should fill up my bra pretty well.” After much giggling, Samantha called out, “No peaking guys, Mom’s changing in the kitchen.” Of course that had the exact opposite effect and James and Aaron tried to peer into the kitchen even though they couldn’t see anyone from where they were sitting.

“Well, how do I look this time?” Mandy asked as she came back into view.

Aaron blurted out without thinking, “You look absolutely stunning Mandy!”

“Thanks, and you Honey?”

“I’m surprised but I really like that look on you. Aren’t you afraid that they’ll be two heavy though?”
