Try to get her to spill the amulet's secrets

You're blunt about it. "I'd like to know what it does".

"I can't tell you."

Well, this requires some more persuasion, and judging by the way she's shyly got her arms folded over her chest you know exactly what to do. You speed up and start removing all her clothes, layer by layer, until she's completely naked - she's still incredibly hot, though this time she seems to have learned her lesson a bit and is wearing more plain, utilitarian underwear, and no garterbelt. You patiently fold up all her clothes, deposit them on your bed, and then grab a nearby chair to tie her to, binding her wrists and ankles to the chairlegs.

"How about now?"

It takes a moment for Evellyn to adjust her awareness to her new position, granting you a view of full frontal nudity. When she does, you catch the flicker of shock in her eyes, followed by a familiar humiliated groan that could only be interpreted as 'not again'.

She pushes her legs together and bites her lip, before replying with emphasis: "I. Can't. Say."

You reach out and start fondling her breasts. She wriggles defiantly.

"Come on, you can tell me."

"No, and you can't make me."

You flash by, putting your hand between her thighs and rythmically massaging her skin, moving up towards her crotch, and then returning to your standing position in front of the chair, where time resumes. You do this multiple times, seemingly not moving from your position at all to Evellyn's eyes, but you can see she can feel the sensations between her legs. Her breathing becomes flustered, her exposed chest starts heaving ever so slightly, her cheeks become redder, until she can't contain herself and lets out a series of shallow gasps, barely managing to stammer out "stop", before she leans back her head and lets out a moan of involuntary ecstasy. Shamefully, she slumps down in the chair, breathing heavily, trying to avert your gaze. You wonder if that'll do.

"I.. * she breathes * .. I still won't tell.."

Apparently not.
