Cheater Part 1

After finding out about his feelings, Lance plays Keith into becoming his 'fuck buddy' due to his current girlfriend, Allura, not wanting to have sex yet. It's hard, to lie to your friend and do something so horrible behind their back, yet he lost all sense of control when Lance came onto him, time and time again. But slowly, it began tearing Keith up from the inside out and started affecting his performance with the team.

Can the Black Paladin, Head of Voltron bring this back, or will it continue eating at him from his depths forever?

Or will he end it before it does?
