Claiming your reward

Your sister slowly gets up and excuses herself to the toilet so you sit on her bed and wait for her return. You left a wet patch of her fluids on her sheets and her bedding was a mess as well. Surprisingly the Jaw-Breakers haven't shrunken by almost anything since you inserted them into her.

As you inspect the candy more closely, you hear your sister enter the room again. Now she is completely nude and she has tied her hair in a ponytail. She slowly and insecurely approaches you and gets on her knees in front of you.

Before you can say something she extends her hand and grabs your dick through the fabric of your pants.

"It's time to collect your reward for saving me big bro", she said and starts to pull down your pants.

You debate in your head how far you want this to go but by the time you recollect your thoughts, your sister already started swallowing your dick.

"Wait a minute sis. What will we do if I get you pregnant? We can't care for a baby. You haven't even finished school and I have no stable income."

"That's ok big brother. We'll make it work", says your sister in the short time your dick leaves her mouth before it disappears inside her again.

You hold her shoulders and move her away from your crotch.

"No sis. I can't get you pregnant. You can reward me in another way. Let's have normal... err vaginal sex and we'll call it good."

Your sis is now pouting and seems upset.

"You don't want to be my baby daddy? Fine, but my pussy still hurts, so I'd prefer if you leave me alone now", she says and pushes you out of her room. She slams the door behind your back and you can hear her start crying as she jumps on her bed.

That didn't go as planned. You should reconsider the rules because making your sister pregnant is not what you wanted after all. You are not even sure where the baby comes out when you impregnate a girl orally. Would the teeth scratch the newborn? That thought is just horrible. You head to your room and revert the rules from your last batch of changes and go to bed.

The next morning you decide to look after your sister. You steal some of her candy that mom impounded and head for her room.

You knock on her door and enter after you hear a faint response. Your sister is still in bed but at least she redressed herself. Her chastity cage is still next to her bed on the floor, however.

"Hey sis, sorry about yesterday. I shouldn't have shot you down like that but I think we both aren't ready to be parents yet."

Your sister looks at you confused but slowly nods but seems like she had a mild headache just now.

"I brought you some of your candy as amends", you say and put the candy you brought on her nightstand. "I can also feed you some like on the couch when we watched that movie a few days back."

Hearing that makes your sister's face brighten up and she removes her blanked full of excitement. Her PJ bottoms follow shortly and she spreads her legs to give you access to feed her. You unwrap a Snickers bar and shove the whole bar inside her pussy.

Your sister moans lightly and closes her eyes, savoring the taste. Next, you rip open a pack of Pop Rocks and sprinkle it on her lips. This gets her really excited and she squeaks happily at the sensation and flavor of the candy. Finally, you unpack a Chupa Chups and push it inside.

"We have to lock you back in your belt now sis. Mom would be so mad if she knew what we were doing."

"Don't leave the stick of the lollypop inside me. It will poke me all day and I can't get it out without help."

You think for a short while and pull the lollypop back out and shove the stick up her peehole.

"There, now you can have a taste every now and then and it wouldn't be blatantly obvious to Mom when she unlocks you for dinner."

Your sister still seems unsure about your train of thought but she rolls with it. Soon after she is locked again in her chastity belt and you head out to look for your mother.
