Do you guys have any recommendation pics to send to a non yaoi reader to traumatize them? Not very explicit but okay to send

This is BDSM based. A guy is in a bdsm relationship with his girl friend and she said no since she got a boyfriend and want to be serious with him. The main character then finds a girl through some app but that girl is very inexperienced in bdsm. They eventually like each other but that guy ends up going to the military service and they meet each other after he comes back. Then the manhwa ends! They don't even have a conversation!!
