Your sister, Bella

You wake up and receive a flood of new memories and knowledge as the goddess teaches you how to use your power. When you leave your room, you can hear your sister eating breakfast in the dining room.

As you make your way to the dining room, you think about what to do. You decide to hypnotize your sister into doing your bidding. You arrive at the dining room.

“Hey bro, what’s up?”

Your sister is dressed as she usually is when at home, in a skin tight tank top and very short shorts. You can see the outline of nipples through her tank top.

“You have a huge fetish for reading stories of girls getting their boobs destroyed. Now you want me to pop your tits.”

You snap your fingers and your sister’s hypnosis is finished. Her tone shifts and she awkwardly turns to you.

“Hey bro… I have a favor to ask you… Uh, do you know what titbusting is?”

“I think I’ve heard of it. Is it those stories where girls get their tits crushed?”

“Yeah… Well I have a huge thing for it. I can’t tell you how many times I’ve came to those stories. And I…I wanted to ask you to destroy my breasts. You don’t have to, but you’re the one I’m most comfortable with asking.”

You pretend to think about it for a moment.

“Ok, I’ll do it.”

“Great! Let’s go to my room then.”

You follow Bella to her room. You two are the only ones home, your parents started traveling frequently for work when you both became adults and able to take care of yourselves. Bella steps into her room and tells you to sit on her bed. She sits in your lap. At this angle you have a great view of her C cup boobs. Her ass digs into your lap, causing you to become erect.

“Do you know what to do bro?”

“Yeah, I’ve read a few of those stories.”

“You like them too? Good, now I know you won’t think I’m weird.”

“But first I think you should strip.”

Bella stands up and turns to face you. She removes her tank top and short. Then she slowly removes her panties to reveal a pretty, pristine, hairless pussy. She notices you looking and spreads her lips to reveal her perfectly pink and wet insides before sitting back in your lap.

“If you were wondering…I’m still a virgin…You can start now.”

You start by lightly massaging her boobs. Bella moans a little as you stimulate her breasts. You keep doing this until her nipples become rock hard. Then you give her nipples a hard pinch. Bella lets out a loud, erotic whimper of pain. You notice her move her right hand down to her pussy to rub her clit. You go back to rubbing her boobs, but slowly increase the pressure a little at a time. Bella’s moans slowly grow more intense and she rubs her clit faster.

“Do…it…bro. Please…”

Bella begs for the destruction of her breasts, and you happily comply. You suddenly crush her tits in your hand with all your might.

*POP*

Bella’s eyes roll back into her head as she feels her boobs give and pop. Her pussy convulses as she experiences the best orgasm of her life. She releases a huge fountain of squirt all over the floor then passes out in your arms.

You lay your limp sister on her bed. Her formerly amazing rack is now just a pair of deflated, sagging bags of skin. Her nipples leak a small dribble of clear liquid. You decide to taste it. It's sweet, maybe vaguely similar to breast milk. The goddess did show you how to heal her tits, but you decide to do that later. Seeing your sister cum so hard from getting her tits popped made you horny. Time to do this to another girl.
