I entered a cubical and sat down. Almost immediately an older guy came into the next cubical and after a while it was obvious he was wanking his cock....He heard me next door and said "so you came in here to wank over that hot piece of ass in the boots outside too?" It then hit me he was referring to my mum! "stick your cock through the hole and I'll suck you off" he said. I was shocked, but so turned on, I did what he said and felt his warm mouth swallow my the head of my swollen cock. "I bet. An hour later I got a text from you and my heart skipped a beat. I had butterflies in my stomach as I read the texts. The first one had asked me if I was ok? I replied that I was. The second one asked me what I was doing? I replied I wasn't doing anything and that I was just sitting here. Then the third one had said to go and look in my garden to see if there were any dodgy guys out there. I shut down my laptop, put on my slippers and went to investigate. I opened the door and went outside,. How crazy. How can such a person exist?’He tried to use more force to get it out, but he couldn’t. Not knowing what to do, he tried to talk to her for the first time.“Hey, let’s get this over with, please? I want to go to the next class, and if you don’t end this now, I’ll end up pissing in your mouth.”Since he came for the second time, he started to feel like taking a piss. He held on for most of the class while the girl continued to have his cock completely in her mouth.A strange thing. I went to grab him a fresh towel and thought I would give him a moment of privacy and wait until he got in the shower to put it in the bathroom for him. I heard the shower turn on and figured he was in and it was safe to sneak back in. The sight that greeted me was his firm backside as he climbed into the shower. That definitely took my breath away and I giggled nervously to myself as I announced that I left a towel on the sink for him. I went back to my room and climbed into bed to keep warm.
