The bell for first hour rang just as we walked inside. I waved at both of them as they vanished down a separate hallway. "You two behave yourselves no...!" I shouted after them."Don't we always?" Kelsey yelled innocently, causing Amanda to giggle.I shook my head as they disappeared from view, noticing in passing just how many guys were staring at them with a hungry look. Knowing the two of them, they'd probably first go find a bathroom to fuck each other in. The mere thought of that made my cock. She then teased my cock with her fingernails for a minute or two, just to make sure it was fully erect, not a problem as I was anticipating what was to come. “Okay, it’s showtime!”I heard two sets of footsteps coming back a minute later. I could see that Cassidy was wearing pretty much the same outfit her mother was. She was a bit smaller than her mother, but a very similar build. She was a soccer player and her legs and butt showed it. Her hair was longer and pulled into a loose ponytail.. As I did I felt a rough, calloused hand pulled my knickers to one side and two fingers entered my pussy." God fellas she's dripping wet and really tight! You certainly weren't exaggerating about her Dave!" Dave laughed loudly as he shot his cum into Mary's eager mouth, I heard her splutter as she spat his cum onto the floor, "Sorry Dave but I never swallow! Never have, seems you have trained your little whore better than me!", she laughed as she moved across to watch me intently as I sucked. After 25 minutes, and a few orgasms, she quietly said, "That's enough for now... Time for you to finish." As I looked at her a little curiously, she continued, "In addition to always being naked in my house, I'd like to ask that you always finish before you leave. I like watching, and besides, I don't want some guy sitting in his car in front of my house and jerking off for all the neighbors to see." Again, I agreed.That's how it started. For almost the next two years I would get messages that.
