The trainees are doing their best to win the first place spot for the chance at having a one on one training session. This time they are letting it all out, with non stop cock sucking, fucking, and intense orgasms. The evaluation of their cock sucking skills has happened, and now we want to test their discipline and orgasm control. All four are put on sybians at the same time and pushed to see how much control we have over them. One by one, they are picked and fucked for the ultimate test.
