As planned, each of us models (five women and me) were introduced by the professor and asked to tell a little about ourselves. This was meant as an ic... breaker and a way to relax. After a few minutes of that, the professor had the models go and sit on designated stools spread around the room. He assigned four students to each model, but told them that by mutual agreement the students could switch “groups”. The only requirement was that there must be four students for each model.

By now, I was crouched next to her and nuzzling in her pubic hairs and murmured: ‘You don’t have to, … at all, … if you don’t want to.’ She didn’t reply, but opened her thighs.
