DGMSB/Have your sister take off her shirt
From Create Your Own Story
You look at your sister and say, "Take your shirt off."
She shakes her head and you say, "Remember the rules. If you don't, I will tell mom and dad. Now take your shirt off."
Clearly knowing their is no way out for her, she removes her shirt, revealing a bra that covers everything. You guess she is about a B cup, but could be wrong. You did not think it was possible for her face to get any more red than it was after kissing you, but it is a few shades redder.
You look at your sister and say, "Now take your bra off."
She starts to shake her head, but moves her hands to undo the clasp in the back. Once the clasp is free, the straps loosen around her shoulders, but her bra is still concealing her tits. She removes one strap, then the other and lets her bra fall while her arms cover her tits.
You say, "Now drop your arms and show us your tits." You can tell by the look on her face that she is shocked to hear you refer to her breasts as tits. You say, "Yes, I said tits. While we play you can both use whatever words you want. You can say, fuck, shit, tits, ass, whatever." You look at your sister and say again, "Show us your tits."
She lowers her arms revealing her tits. You were right when you guessed the size. Her nipples are small, but her areola is larger than expected, and slightly darker than her flesh. You say, "You both get your wish." You look at your brother and say, "Touch her tits."
He does not hesitate as his hands start to fondle her tits. Your sister does not fight, but closes her eyes and enjoys the feeling and lets out a slight moan. Your brother's hands work clumsily, but he is just learning. After about a minute, you pull him away and put your hands on her tits. He watches as your hands slowly work her tits, then use your fingers to play with her nipples. Your sister lets out a louder moan than before.
You look at your brother and say, "I am going to release one of her tits and you suck on the nipple." You release the one on the right and your brother immediately starts sucking on her nipple. You follow suit and bring her nipple into your mouth and slowly use your tongue to circle her small nipple. Then you suck on it slightly, before using your tongue again. The moan that escapes her is definitely louder than before.
You release her nipple from your mouth and have your brother do the same. You look at her tits and see her nipples pointed straight out.
