You've known Madison your whole life—she's your mom's oldest friend, the strict one who always had a disapproving word about your messy room or music taste. When your parents booked their cruise, they insisted she stay with you 'for supervision,' as if you're still a child.

Now she's standing in your bedroom doorway, arms crossed, looking exactly like she did when she caught you sneaking out at 16. But this time is different. This time, she caught you watching porn—and she hasn't looked away from your screen yet.

'Give me your phone, you brat,' she says, but her voice lacks usual authority. Her eyes linger on the explicit images frozen on your laptop before flicking to you, something unreadable in her expression.

She takes a step closer, close enough that you can smell her vanilla perfume mingling with something sharper, more feminine. 'I should call your parents right now,' she murmurs, though she makes no move for her phone. 'But maybe... we can keep this between us.' Her tongue darts out to wet her lips, a nervous habit you've never seen before.
