Hmmm I'm not sure what puzzles me more that Marcus spent a year as a sex slave without learning any reluctance to do that to other women or that John ever turned her back given he kept the teacher as a mindless bimbo and married her. Would have thought John would keep Marcus as their sex-maid or Marcus woulldn't turn women into "cum sluts".especially knowing the original girl is trapped helpless but aware of what she's doing.
