Your step-sister walks into the kitchen and stops cold. There you are, mug in hand, that familiar tea already half gone... She knows what it does.
She remembers last time, the way her body couldn't contain it, the way her step-brother's cum pushed past her lips in thick waves while you both watched in disbelief. What catches her attention now is how hard you already are. Bigger than before. Thicker. She can't help but stare, longingly.
You had talked about being able to do more, but questioned if it was all too risky. With the amount of cum last time... she doesn't know if her birth control could handle it...
She's trying to be responsible. She's trying to talk herself out of this. But her words carry her closer anyway, her body betraying every rational thought. She wants it and she wants you. She's willing to risk it all to feel you inside her again, consequences be damned...
