Tess prided herself in her oral skills and did her best to please her new mistress.   It wasn't that Tess knew of Cass's own superior skills in that department.  Tess wasn't into the occult, and only had a fleeting notion of what a succubus even was.  But she was the kind of girl that like to excel at everything, and she did nothing half- hearted.  That- coupled with an almost serpentine tongue- seemed to keep Cass happy at least for the short term.<br/><br/>Then she noticed Cass's vagina seem to get bigger.  The lips grew thicker and wider.  Somehow instinctively Tess knew what Cass wanted her to do.  She moved just a little forward, and Cass's eager lips moved to grip the girls head.  “Ooooh!” Tess exclaimed as they gripped the top of her head and pulled her forward.  Tess then put her arms to her sides, and slipped in to the now yawning chasm past her shoulders.  The inside was slick and in an instant Cass's sex had engulfed her entire body.  The bulge in the demon's belly was enormous now, having not only taken on the bulk of her lover's body but two souls as well.<br/><br/>At that point Tess's soul exited her body to join Azric in the demon's stomach.  Her lifeless body would be held somewhere below until the time that the succubus decided to free her.<br/><br/>Azric- still held in the demon's belly- recognized his girlfriend's soul immediately.  It resembled Tess, although it glowed a bit and was a bit transparent, almost like a ghost.   The two of them embraced, relishing being in each others arms and the bliss of having their souls free from the confines of their bodies.<br/><br/>“I want to make love to you in here, Tess.  Just being here is almost orgasmic...I can't imagine what will happen if we try to do something to add to the pleasure”.  Azric didn't need to ask her twice.  She lay back and Azric came to her.  But rather than simply penetrating her, the substance of their souls seemed to merge.  Though it wasn't what they expected, the sensation of their souls touching was more like the sum of every orgasm they'd ever had.  It was the kind of ecstasy that mere mortals weren't meant to experience, at least while alive.  As the two of them drowned in the pleasure, Azric wondered if Cass could feel this.  And if she knew that this was going to happen.
