Back in town after my trip and last night I was super horny and really wanted to fuck. I made it very plainly known when we got into bed and she shot me down hard. Said she didn't feel well and that I could just jerk off instead. I took this to mean that she wasn't interested in fucking me because she had plans to fuck her boyfriend the next day. Needless to say, that got me even more turned on. So I decided that I'd go ahead and do it. Usually I wait until she's sleeping and then just lay in bed jerking off next to her imagining her fucking other men, but last night I actively jerked off to her while she laid there away. Apparently it was either a turn on for her, or she felt like it was simply too pathetic, because she changed her mind and let me fuck and cum in her instead.
This morning the texts/timing lined up with her going straight into the office (maybe a 10 minute gap, but usually when she meets him it's 20 min). Not sure what to make of it. I'll post an update once she's home and I have a chance to review the recordings.
EDIT: This evening I had the chance to do a very brief snoop on her phone. Pulled up the web browser and checked the history. It had been very recently cleared (only 2 sites showing). She has never turned off web browsing history, which means she is manually clearing it herself regularly. I've found this is her way of covering her tracks when she accesses her secondary gmail account. So that dashes hope/thought that perhaps she ended her relationship with her boyfriend. It makes me think that perhaps she has gotten wise to my methods and changed her own - as she has done in the past.
