Visiting the sex shop

Most of the morning is spent just as you said, in bed with Sofia, stuffing her womb full of your potent teenage spunk over and over as she moans and spasms around your thick cock. After emptying your bloated balls into her for the fourth time, your nuts feel sufficiently empty enough for to feel satisfied and act normal again.

"Hey Sof, I think I'm good for now. Your hot little pussy is really good at milking the cum from my balls."

You see her smile and press herself back against you to cuddle, your cock softening in her sperm soaked pussy.

"How do you feel lil sis?" you say, running your hands up and down her slender body.

"It always feels good when you shoot it all inside me John. My belly feels hot and full" she says, rubbing her abdomen about where her womb would be.

"I'm glad you like it" you whisper in her ear, tilting her head back towards you and giving her a deep kiss. She's shocked at first, but quickly closes her eyes and relaxes, kissing you back.

"You never like to kiss" she says, breaking away from you and looking you in the eyes. "It always felt like there was a part of you ashamed to be using your sister for sex relief."

"Let's just say I'm starting to see you in a whole new light Sofia." You lean in and kiss her again. "Get dressed, I have a surprise for you."

You smirk as she climbs out of bed, looking tired and disheveled from the hours of steamy sex. With a grin you yank up her cum soaked little cotton panties, the damp material clinging to her smooth pussy and showing off some nice cameltoe. You don't even give her a chance to clean up before you're rummaging through her dresser, tossing a short black skirt, white bra, and a pink shirt at her. She doesn't question it, and gets dressed exactly as instructed.

Soon you're dressed as well, and lead her to the car. Using Google, you look up nearby sex shops and find one that looks appropriate. Dark and seedy looking, and sure to have some of the fetish gear you're looking for.

It takes you 20 minutes to get there. Sofia is a bit surprised when you arrive. You help her out of the car and walk behind her as you approach the shop. She reeks of sex. With her short black skirt, she's so full of spunk after the last 24 hours that you can see a lines of cum running down the inside of each leg as she walks, all the way to her socks where it soaks into them. Sometimes a drop of seed drips off of her and splatters directly on the sidewalk. Your little sister is a walking wet dream.

"Holy shit, what a sight!" you think to yourself, your cock already getting hard again. You know its going to be an incredible experience turning Sofia in your obedient and pregnant bondage breeding ****.

Walking into the shop, Sofia's face is flushed with embarrassment as you pull her inside. The door chimes, alerting the staff to the presence of a new customer.

You hear someone whistle loudly, and you and Sofia turn to see the source. A tall man in his late 30s, with a shaved head and a well groomed beard. He's reasonably fit, and probably a bit above average looking. Not the typical sleazy fat old man you were expecting to run a place like this.

"Now that's something I don't see every day" he says, eyeing Sofia up and down, the cum running down her legs clearly visible. To her embarrassment, another drop of cum leaks from her panties to splatter on the floor. "Looks like you two already had a good time. Are you two even old enough to be in here?"

"Barely" you smirk back at the man. "But hey, 18 is 18 right?"

He nods, taking in your appearance once more. "Right you are. So what can I do for the two of you?"
