Wow, it went in<em>perfectly</em>, no force necessary at all!  And it was so... so tight, so<em>perfect</em>!  This had to be the most amazing ass she'd ever been in... it massaged her and drew her in, sliding more and more into her at the snake-woman's own request, that tight hole and slightly-slimy sheath hugging and caressing her... until she felt her neatly trimmed pubes tickle the woman's asshole, and her balls resting against warm pussy-lips.<br/><br/>"Wow..." was all she could manage to express her amazement at the feel "...you... clearly do this regularly!  Means I can try good and hard to wreck it!"<br/><br/>And so she would, sliding back out, and then<em>slamming</em>back in!  The woman could take what she dished out, that was for sure, and so she' started dishing it out as she held that tail between her breasts, the other hand gripping the ass to help her thrust in.  The bed was soon creaking, sliding across the floor from the thrusting into the woman's ass, her legs and hips pistoning like the whore she was as echoing slaps pervaded the room and beyond.  She was going to wreck that asshole so hard... and Petra knew a good ass-fuck and this woman obviously did too; both of them would be cumming from this, that was for sure... and Petra even managed to toss a bit of rope onto the bed, so that after she was done railing this asshole the snake could simply remove herself from the cock, tie her arms to the bed... and then ride her before she turned the tables on her and fucked her tits...<br/><br/>Yeah, one of the best, most fun ideas she'd had in a while with this, Petra had to admit...
