If he'd intended to do this to her, she loves every second of it. He's probably rarely, if ever, had the chance to fill anyone to this extent. She's all too happy with the turn of events, and she's sensitive... almost everywhere. When he shifts his tentacle inside of her in the new way, it keeps the waves of pleasure coursing through her. He just won't let her rest will he? Her cock twitches inside of his mouth as he sucks on it, and she attempts to form words.

"I... god... Oh my... you..." Is about all she gets out, she's going to need time to regain some form of coherency if he expects anything out of her. If not, he could easily keep her in post orgasmic bliss for as long as he wanted. Maybe even bring her to a third climax, honestly, it's not like her cock ever stays soft for long.
