Every rough, powerful thrust of the hellhound's enormous member sent Sigyn's body rocking back as she lay there, her breasts bouncing and jiggling from the force with which she was being taken.  It wasn't exactly easy, taking that knot over and over again, but now that she wasn't fighting against it anymore, the giantess was certainly enduring it better than any human would have.  Stone giants in general were not a race that was known for being gentle during sex, and Sigyn was, herself, not exactly a virgin, even before the beast began to have his way with her.  Needless to say, as the hound continued to pound away at her, the giantess' body adjusted more and more to the act...<br/><br/>"Unh...  I... uh..."  Suddenly switching gears and wanting her to talk, however, was going to require a little more adjustment.  "I... want... it...  I want... more!  Please, don't stop...  I want you to keep fucking me, I want you to give me more of your seed!  Nnnh...!  Please, fill up my pussy, get me pregnant!"<br/><br/>It was a bit of a rough start...  But she was actually getting into it towards the end, there.
