Piper gives Jonas a smile. "I have to admit that I worried the same... that Siv would decide she was happy with you, and didn't need me on the side. But that was before I saw, through Siv, what she loved about you, and fell in love with you myself."
And nodding to Siv's comments. "I admit that it rankles me a bit too, when I get looked at as a satyr easy lay first, and a person second. Sure, a quick tumble is fun, if that's all you're looking for, but it shouldn't be granted as a given that that's what all satyrs want, or are good for. But..." She reaches for Siv's hand, and one of Jonas's, and squeezes them both. "I can't promise that I'll never 'slip', as you put it. I don't know the future.. I am a satyr, for better or for worse. And that means, to some extent, I am ruled by passion, and there are times when I might be carried by Gift of Pan as well. If I said I would avoid every situation where that might happen, every after-party, every tragos bash or rock concert or whatever... it would mean denying some part of my own soul."
She swallows, and continues. "...but I can promise that I will never intentionally do anything to hurt either of you. I'll never DECIDE I want to schtup that cute barista, or pursue one of my dreamers past fingering... musical, that is, sorry Jonas. I'm not going to go SEEKING new conquests or lays or what have you, as like you said, there's no need for any of us three to ever suffer from boredom in the bedroom."
Looking from troll to trolless, worried. "Does that make sense, what I mean?"
