...Best Damn Tapper! *Most Smartest*

Oh, very interesting (and yes, I know I haven't commented on the previous fic, real life, why must it torment me?). I'm not so sure - there' still the Nora angle to consider. I mean, she just recently got back with him, and we don't know if she ever shared him with anyone. They're not master and progeny like Eric and Pam and Pam and Tara - they're siblings, so there's no defined power structure - they're equals. And since they just got back together, and Nora never knew Pam... well, I'd think she'd be jealous of Pam, and object to Eric doing anything with her, and especially with Pam and Tara. As far as we know, they don't exactly get along, each being possessive of Eric, feeling they have a better share of him. So... I can see this scenario, Eric just thinking about it and Pam suggesting it, but without Nora agreeing (which seems unlikely, unless she get to participate as well, which seems even more unlikely considering how her and Pan interact regarding Eric) I don't see it actually happening, unless Eric wants to get into a fierce argument with Nora.

Wow, I probably over-analyzed that to the max, right? But anyway, actual point, it was a very hot fic, great character interaction for both Pam and Eric and Pam and Tara, and I can definitely see it happening - but with the qualifications I wrote in the above paragraph, vis: Nora's consent (either involving her participation or a prior converse with Pam and Eric) or Nora's fury.
But if you write it without that happening, I'm sure I'd still totally love it.
