Xavier wasn't bashful after his confession of possibly feeling possessive of Robin.  He didn't claim to understand Robin's position on gender very well but he knew he liked what he saw in them.  He also knew himself pretty well, he was something of an alpha male and while he knew he had to adjust, he wasn't going to totally change his stripes.  He felt Robin read him pretty well and probably knew that.  Did they know what they were getting into here?  Did he?  His confession didn't drive Robin from his presence which was a relief, he really did want to spend more time with them, both to learn and to, well to fuck.  But not that wasn't quite the word was it, but did it really matter, it was highly pleasurable, this nonpenatrative sex.<br/><br/>He did blush as Robin explained that they and Abigail had discussed their disastrous sexual encounter over lunch.  He got over, his interest piqued as they said he did too well which wasn't at all how Xavier had thought about the evening before.<br/><br/>"You!!??"  He sat up straight in his chair at this realization.  But it wasn't anger brewing inside of him even as Robin's nod and look confirmed what he had been trying to tell himself didn't happen.  But was Abi really cheating on him with Robin?  They didn't have a penis so it wasn't like Robin had fucked his wife.  In fact, in Xavier's view of the world, he had come much closer to cheating with near intercourse than anything he imagined Robin and Abigail doing together.  But maybe that was his own limited view of the world.<br/><br/>"I don't know about no sex."  He protested mildly.  "But I know I really enjoyed our time together."  Though he wanted to enjoy his time with Abigail as well.   If only there were a way for the three of them to come to some understanding.  And then they said it.<br/><br/>"A threesome!"  Xavier nearly spit out his coffee.  "Are you putting me on?  Abi agreed to this?"  He asked, not fully believing what he was hearing.  Was it some sort of entrapment, a way of proving his infidelity just prior to her seeing a divorce lawyer.<br/><br/>"And where did you two decide this threesome should take place?"  He asked, his mind barely comprehending the possibility, much less the logistics of it.
