Erotica Sex Story: Chapter 6: The Audience Grows - Samantha returns from a mysterious trip with newly enhanced boobs. Aaron is impressed, but things really get interesting when Mandy stuffs her daughter's bra and loves the way she looks and the reaction she gets. If Aaron can't keep his hands off Samantha's chest or keep from jacking off in front of everyone because of her new boobs, what's going to happen when Mandy decides to go even larger than her daughter, much larger?

James asked, “Who needs to be careful?”

“Come look at this!” Aaron had removed the condom, and Mandy had taken it from him. It really did look more like a water balloon than a spent prophylactic. Samantha shyly pulled a blanket over her exposed pussy, and Aaron held his hands over his half hard cock.

“What the fuck is that? What the fuck is going on in here?”

“I caught Samantha deep throating Aaron. They were obviously going to start having sex soon, so I made sure they knew how to do it safely. However, I don’t know if safe sex exists in the face of something like this! I’m still amazed it didn’t explode inside Samantha’s pussy from being overloaded!”

“What? No way. You guys are pranking me! Having Aaron and Samantha both with their pants off is pretty over the top for a prank, don’t you think.”

“I swear this is one hundred percent not a prank! I just watched Aaron cum like a fire-hose inside my daughter. Can you two go at it again later tonight?”

“He can probably go again now,” Samantha said dreamily. “He came twice in a row easily enough last night when I was sucking his cock.”

James was stunned, “You were sucking Aaron’s cock last night?”

“Catch up honey. I caught Samantha deep throating Aaron. She didn’t figure out how to do that in the ten minutes between when you left for the store and when I caught them. Obviously she started sucking his cock last night, if not earlier.”

Samantha protested, “Last night was the first time.”

“And by your own admission, the second as well. Whatever, it doesn’t matter now. James, go get them another condom so Aaron can show you I’m not lying about how much jizz he would have flooded Samantha’s pussy with without one.”

Aaron rolled a rubber onto his mostly soft cock trusting that once he was back between Samantha’s legs, he would get hard again. However, Samantha kept trying to hide her pussy from her parents and Aaron’s erection did not return.

“This is weird doing it in front of you two. And Aaron doesn’t seem to like it either.”

“Why are you so shy about this when you’d happily show your tits to complete strangers?” Mandy wondered. “That’s probably the solution to this problem. Take your shirt off Samantha.”

“What?”

“Listen to your mother; get your tits out. Lose the shirt and bra.”

Aaron could feel his cock starting to swell as he watch the teen’s shirt come off and stared at the full domes of her bra covered breasts. Then she unhooked the strap behind her back, and he felt his cock swell further. When she freed her arms from the straps and tossed her bra onto the bed, Aaron became fully hard. Samantha’s enhanced rack was just too appealing for his cock not to respond no matter who was watching. However, it was James who spoke first, “Damn! I know I said she shouldn’t do this in front of Aaron a few nights ago, but I love seeing those giant puppies come into view. And now my wife has even bigger implants!”

“I guess it’s a good thing I got a set of my own fake knockers so I can compete if you’re going to be perving on my daughter like that,” Mandy teased.

Aaron grunted as he found Samantha’s pussy and started rubbing his hard knob on the outside of it. “Oh yeah, seeing Samantha’s tits was just what I needed,” he sighed before adding, “But now I need to be fucking you again. I can’t believe your mom made us have sex, but it felt so good being inside of you.”

Samantha agreed, “It’s just what I need too. I think Mom was right, the way I took to sucking your cock I’d have been spreading my legs for you within the week Aaron. At least that’s probably what would have happened if Mom hadn’t convinced us to start having sex tonight. Now I’m happily spreading my legs for you right now! Ah, ah, ahhhh!” The teen wailed in pleasure as Aaron’s cock slipped inside her. Aaron didn’t waste any time, urgently thrusting in and out of the sexy teen while her parents watched.

Any thoughts Samantha had of shyly hiding her pussy faded as Aaron sawed his dick back and forth in it. She even pushed the blanket away so she could get a better view of Aaron’s cock vanishing between her legs.

“This is crazy!” cried James. “Look at the way her titties wobble every time Aaron thrusts into her. Fuck, I can’t wait to get Mandy on her back so I can enjoy something like this first hand!”

“It is kind of mesmerizing, even for me,” Mandy admitted. “I can’t take my eyes off my daughter’s big boobs; I can’t even imagine what they’re doing to you guys. I do know I’m going to feel so sexy when I finally get to reveal my new boobs!”
