Zorlun I have to confess two of my favourite kinks are anal and gangbang, often combined!!
You have been most kind to give us two great examples in recent updates, first with the university students after the gala and second with Anthony and his work colleagues at dinner.
One of my favourite fantasies is hot teacher being gangbanged by her students. Now Myriam only has a small group for gymnastics, but there are presumably many others sports teams at school. I am sure you could come up with many such scenarios. e.g. Myriam accidently walking into the wrong changing rooms. Or the female showers are broken so Myriam risks going into men's showers thinking that everyone else had gone home....
And of course that could easily lead to more shenanigans. e.g. she is spotted by / reported to one of the other male teachers, leading to sex with one or more of male teachers / principal.....
The thought of the football team's running a train on Myriam - no jokes about Wide Receivers or Offensive Tackles!!
