Andrea had always been repulsed by anal.   Just the very thought of it had turned her off, and she had several times had to forcefully resist a partner's advances in that area.   Indeed, the beast's phallus had been the first foreign object to ever penetrate her anus...and that had truly been a humiliating, painful experience.  So it was quiet a shock to the small part of her mind that remained somewhat lucid that the renewed probing of the tentacle sent a shock of pleasure through her body.   The hormones the creature had flooded into her had heightened the sensitivity in her body almost to the point of breaking.  Thus, even the slightest touch of the tendril to her pussy cause her to lay back her head with an animalistic howl as the throes of an orgasm surged from between her legs.
