Silver won't refuse to be of service for his dormmates, he's such a self-sacrificing and sincere boy...
It all started when he agreed to help with one of the alphas' rut, he was in so much pain, poor thing. Silver couldn't stand to just silently watch when he was able to minimize the suffering. He assumed that one night stay wasn't a big deal, but pretty soon other alphas came for his company too
It became worse when they stopped asking, just took what they wanted even when he was asleep. Silver awakened with cum in his hair and pain in his lower body more times than he was willing to admit
At some point he just accepted it, letting eager alphas and betas have their way with him, pull his hair or violate his insides. It wasn't unpleasant since omegas' bodies were created specifically for that, his instincts made him happy to be used
