You're chilling out with a book when your step-sister comes barging in saying she's super bored and wants to hang out. She suggests that you play a game, reminding you of how you guys used to play truth or dare all the time when you were younger... It could be fun to give it another go? You're not fussed but you can tell that your step-sister is not in a mood to be denied, so you sigh and agree. Your step-sis starts off and you do a few rounds of truths, with your step-sister mischeviously asking you if there's anyone you have a crush on right now.... You tell her there isn't and she seems...

You're chilling out with a book when your step-sister comes barging in saying she's super bored and wants to hang out. She suggests that you play a game, reminding you of how you guys used to play truth or dare all the time when you were younger... It could be fun to give it another go? You're not fussed but you can tell that your step-sister is not in a mood to be denied, so you sigh and agree. Your step-sis starts off and you do a few rounds of truths, with your step-sister mischeviously asking you if there's anyone you have a crush on right now.... You tell her there isn't and she seems surprised and disappointed, but carries on with the game. After a while she seems to be pushing the questions in a more risky direction, asking you when was the last time you masturbated? You start sending her questions back at her, and she tells you happily that the last time for her was last night! You're feeling a bit weird about this game by now but she's giggling and egging you on, asking you next if you ever had a sexy dream about her...? You're shocked that she would even ask that, but when she keeps pushing you admit that okay, you did have a sort of weird dream about her once. She makes you tell her what happened in it, and you reluctantly tell her that you dreamed that you touched her boobs... She laughs at this but doesn't seem mad or grossed out! You begin to feel bold enough to take a dare turn, and to your surprise she dares you to touch her boob in real life... She pulls her top down to show you one boob, egging you on until you do it.. Then you decide fuck it, and dare her to take her top off. She does this with no arguments, cheerfully peeling her shirt and bra off to sit before you topless. Things start really ramping up now, with her daring you to take your pants off, and then you daring her to do hers.... Soon you're both naked, and though you're not quite sure how this all happened you don't want to stop playing... Your step-sister dares you to touch her pussy and when you do it you find that she's soaking wet.. You dare her to suck your cock, and before you know it your step-sister is on top of you, teasing and sucking your dick before daring you to go the whole way and fuck her! She sits up and slides your cock into her pussy, riding you as she tells you about how crazy this is but how she's wanted to do this for ages, she just didn't know the right way to approach you about it... She rides you in cowgirl and reverse cowgirl, then you fuck her hard in doggy until she cums all over your cock, begging you to fill her pussy with cum... You give her what she wants, and then watch as your creampie dribbles out of your step-sister's pussy all over the bed!
