She tries to seduce you

your girlfriend keeps on complaining about the little sister all night. Eventually she goes to bed early. And the rest of the little Homeparty still ongoing, even though things that calm down. You eventually end up in the kitchen with her little sister.

You feel awkward for a second, but you noticed that she moves extra seductively and plays with her hair while talking to you. She eventually brings up the topic:

‘so as a true what she said? Would you last that long with me? Hypothetically, of course.’

‘Yes, I’m sure I would’ you respond.

‘ I think you wouldn’t, I just wish there was a way to find out…’

‘ I would never do that’

‘ oh, right, she said you wouldn’t wanna touch me.’ the little sister says well taking your hand.

‘ that’s right’ you say while not moving away from her hand.

‘ not even here?’ she says, while slowly moving your hand over her flat belly slowly towards her breasts Until your fingers touch the side of her perky boob through the thin fabric of her top.

‘you need to stop, ’ you say indecisively while just slowly moving your hand away. You are very aware that anything you do with her here, she will happily tell your girlfriend about in every detail.
