Just an instant rejection of the hypothetical. I paused—that wasn’t what I’d been expecting.“You have no trouble cumming, even though you know...I can’t?”“Yes.”“It doesn’t affect it at all?”“No.”“Why not?”I swear I saw a proud smile appear on my sister’s otherwise-neutral face as she replied.“I never have any trouble cumming.”Damn it.I mean, on one hand, that was super hot to hear—and think about.
