Before my mother headed back to work we had figured the best time to install the location app onto my father's phone was while he was in bed. Mom said she'd bring it to me as soon as he was sound asleep which was usually around eleven.
A text from Anne arrived just after mom had left. She told me she'd forgot her phone when she left in a rush first thing and had wanted to message me all morning to see if I was free that afternoon. She seemed to have no inclination her mother might have checked her phone and I'd already decided I wasn't going to mention meeting her mother earlier.
Needless to say I hot footed it over to Anne's for the second time that day and we had a very satisfying session in her room. Ordinary straight forward almost vanilla sex. It was actually quite refreshing!
On my way to see Simon after leaving Anne's, Diane text to see if I fancied picking her up after her lesson.
Simon was even more buoyant than the last time I'd seen him. He told me about a threesome he'd had with Wendy and a friend of hers. I asked for details and he told me her friend was a lot a fitter than Wendy but he had a suspicion she might have been gay as she'd had a fascination with Wendy's pussy and hadn't let him fuck her, but she'd been naked and he'd fondled her boobs!
Like usual Diane could hardly wait to get to our spot and have fast hard sex before making out at a more leisurely pace. We chatted like we always do and for maybe the first time I started see her as someone I could see myself settling down with.
I was in my room reading a required book for my course when mom silently stole into my room around eleven. I was lying on my bed in my shorts and she had on quite a plain nightie. She handed me the phone and sat very close to watch as I installed the app which would allow us to track dads movements. Mom was so close I could feel her nipple rubbing my upper arm, I was sure she must have felt it too.
After I'd set the app up I opened my phone and showed her the marker on Google maps relating to dads phone. I should mention, my mom is a bit of a technophobe with some things but she readily grasped what it meant.
Before she slipped out of my room as silently as she'd entered we were both standing facing each other. I could easily make out the outline of her boobs as her nipples were by then quite hard. I could just made out the darkness of her pubes too. Moms gaze slipped down to the tent my dick was starting to make in my shorts. We stood like that for maybe ten seconds, it was like there was static buzzing in the room, I'm sure my mother felt it too as she had a look on her face similar to the time she had watched me with Mary.
The spell broke when she said she'd better get back to bed. She kissed me briefly on my cheek and left quickly after saying good night.
The next morning she was in quite a cheerful mood. Dad had been gone twenty minutes and she asked me to check where he was. My phone showed us he was where he was supposed to be, at his office. I asked if she'd found any more evidence and she told me she hadn't noticed anything but hadn't started really searching yet.
On a whim as she was leaving I asked if she could get back at lunch time but she told me she was tied up all day. I did think of seeing Mary anyway but at the time I actually didn't feel like it. After a slow start I got into my studying every hour or so checking in on my dad who according to the app never budged from his office. Even at lunch time he only went a few yards to a sandwich bar and back. I knew he always left work at five and watched him drive steadily back only stopping once for fuel.
For some reason I didn't want to be home when he got in so I went to see Simon who was still happily reliving the events of the previous day. We played a few games on his computer and at seven I got a text off mom saying dad had said he was going out in a bit. I told her I'd be back in ten mins.
I passed dad in our hall way, he said he couldn't stop and was out the door. Mom was in the kitchen. I sat on a stool beside her and together we watched where he was headed. When he stopped he was right outside Diane's house!
I took a few moments for mom to work out where he was but when she did, boy did she swear! I'd never heard her say most of the words before. It was all I could do to stop her going around to Mary's with a baseball bat.
Eventually she calmed down. But when she did, she began to cry. I got off my stool and hugged her as she sat on her's. As tough as she wanted us all to believe she was, my mother appeared to be the same as everyone else when push came to shove.
After a while she stopped sobbing but I carried on holding her until I felt her pull away. Mom looked at my shirt and started laughing.
'Look what I've done to your shirt!' she exclaimed. 'I'm so sorry Paul, what must you think of me.'
'Mom, I've no idea what you mean. You just found out dads cheating on you. You have every right to shed a few tears.'
'I wasn't crying over your father getting his rocks off or his backside caned by that slut. I was crying because it seems like everyone in the world is having fun but me!'
This semi outburst surprised me. I reminded her what she'd got up to a few days ago. She grudgingly admitted she had enjoyed slapping Mary, even more so now! What about parading around in front of me, nude. I asked.
'Ok. I get it I have been having a little fun recently, but I still feel like it's passing me by.'
