The Princess Wants To Go Out
Seems like I did not hear her incorrectly… All those times that Lisa had me roleplay her 'rape', Aaron had either been close enough to hear us or arrived just in time to see me finish or close to finishing.
Apparently the 'sob' I heard the first time in that shower cubicle was from Aaron on the other side of the wall. Lisa seemed to have 'accidentally' told Aaron the wrong bathroom to find her in and there was just 'coincidentally' a peep hole drilled there where he could see his 'girlfriend' being raped.
But because the hole was too small to see everything and the running water pretty much muffled our voices, he could not actually confirm that it was who he thought it was on the other side of the wall.
Even then, the seeds of doubt would have already been planted in his mind, causing him to question if the other times he 'caught' us were actually Lisa or someone else.
