My cock was already fully hardand I hadn't even pulled them on yet. I savored the moment with Katiewatching me and I slowly settled them into place. I...wanted to touchmyself, but I focused on Katie instead. She was looking through thedrawers and pulled out a padded bra. "This is a Victoria's SecretBombshell bra. I think you'll like this. Hold out your arms." I held outmy arms and she slipped the bra straps onto them. Walking behind me, shepulled the bra onto me and clasped it. She whispered in. Then my wife sat beside me and we mutually left a thigh air gap that was of a piece with our decade of sexless marriage that brought us to the eve of 45 years. But now it was her sister, Pamela who scooted into the middle for the return to her home where we were guests.At first I hardly noticed. But a synapse crackled and I became aware that Pam's calf pressed cozily against my own once she settled in. My initial impulse was to slide my foot over slightly to give her room. But my inhibitions. .. but she said "shush" so i just lay back and enjoyed her handywork on my cock.I wasn't far off cumming and thought i'd better warn her even though my deep breathing sort of gave it away, her hands were hardly touching my cock just the nylon gliding up and down my phallus, I'm sure she'd done this many times to my grandfather the lucky git no wonder he didn't give in easily to cancer, he had this to live for, she was so skillful with her actions.After telling me to be quiet, a weird thing. Dickson sighed heavily, picked up her sports bag and handbag and walked out of the PE block, locking the doors with her keys. She headed home that evening upset but knew what she had to do that following morning no matter if she wanted to or not.Holly and Daisy sat nervously in the assembly hall the following morning. They had avoided speaking or even looking at their Form Mistress, Mrs. Dickson, and simply had taken a seat and kept their heads down. They hoped that their young Form Mistress.
