Accept the card

You take the offered card and put it in your wallet while handing the bearded clerk the $220 in cash to help pay for the gear you bought. The clerk said some of these people are wealthy and into the lifestyle, and at your age with your lack of funds its never a bad idea to make some powerful connections. You're curious about the mystery woman he mentioned.

"Sounds interesting. We'll be there" you tell the older man as he hands you your bag of goodies.

"Just come dressed in something neat and casual. Nice jeans and polo shirt would do for you, maybe a dress for your woman."

You nod to the man and turn to leave, Sofia following you. Soon you're back in the car and driving home. It doesn't take long for you to reach your destination. It's only mid day on a Tuesday. You and Sofia skipped school to fuck and go shopping, and your parents are still at work for several more hours. Plenty of time to use your sexy little sister's holes to get your rocks off again and again.

You can feel your cock harden in anticipation. You're still not quite sure how the contract you signed works, but you know one thing. If you don't empty your balls regularly they get backed up and start to hurt. You cock got bigger, your refractory period after ejaculation is almost non existent, and your semen production is in overdrive. Fortunately you have a little sister all too eager to help you with this problem.

You pull Sofia back into her bedroom. Its still destroyed from the other day's activities.

"Sorry Sof, I got carried away and ruined your room. I'll help you clean it. But right now..." you trail off, the bulge evident in your pants.

Sofia eyes it, then reaches out and rubs your erection through your pants.

"It's okay John, I know you didn't mean to do it. You just got carried away. I know how your balls hurt when you get backed up. Please cum in me as much as you need."

Your cock twitches in your pants, and you reach out to her. Gently you lift her shirt over her head, followed by her bra. Sofia loosens her skirt and lets it fall to the floor. Her cum soaked underwear is glued to her crotch, drying trails of spunk still visible on her legs. You admire your earlier handiwork, then reach out and start grope her small but firm b cup breasts. They're perfect, smooth and blemish free little bumps with a quarter sized areola and a hard little nipple. You rub them, teasing her nipples with your thumbs.

"How big do you think these titties will grow once I get you pregnant?" you say, continuing to teasing her.

You hear her breath catch in her throat, and see her eyes turn to a packet of pills on her desk. You walk over to them and pick them up.

"Are these your birth control pills?" you ask her, waving them in front of her face. She nods, her face flushed.

"Would you flush them down the toilet for me, and promise not to take any more?"

Wordlessly she takes the packet from your hands and pops out each pill, one by one until its empty. You follow her to the bathroom and watch her drop them in the toilet, then flush it.

"That's my sexy little sister" you whisper in her ear, turning her around and kissing her. She melts into your embrace, kissing you back passionately. Breaking off the kiss, you pull her out of the bathroom and into your bedroom.

"Sofia, from now on you won't be on any birth control. Since I ruined your room and its going to take awhile to clean up, every night you'll be sleeping in my bed." Your hand roams her body, then slides up to touch her choker that reads "Breeding Bitch." You lean in close, your body pressing against her slender frame. "At least until those pregnancy tests come back positive."

You little sister rubs herself against you, nodding her head in acceptance. You pull her onto your bed and look at the clock. "Several hours till mom gets home. How many loads do you think I can pump inside you before she gets home?"

"Knowing you, half a dozen. Your balls are incredible" Sofia says, lowering her panties. Her smooth, perfectly shaven innie of a pussy is on full display, still leaking cum from earlier. She leans into you, her face flushed with desire. "Make sure I'm leaking your cum all night big brother."

You drag her to your bed, eager to make sure that happens.
