LOL, well Well WELL ... who's this in the gallery section ... Don't sweat it too much Hyun. Yes, she's gonna be mad and she might say on the outside that she can't believe or trust you any more ... but on the inside, deep down in her instinctual brain, she want's to know what that dick do. She kinda already knows what it do but not since the 'upgrade'.
So, what do you do Hyun. You've got two choices here. Keep going and make Sophie nut hard. Or stop and lose both. Even if you stop she's still gonna be mad at you but then Sophie also gets mad, LOL. Not that you really care about Sophie. But if you keep going you show the FMC that she can be replaced AND that other women really enjoy the D. Decisions, decisions.
Anyway, Next Stop "The trains pulling away from the station. If you missed your train you can catch it on the next pass". The Chadification of Hyun continues.
