Merciful in the End

This is a not-OOC Snarry. T/W for rape, sex with a minor. After Voldemort is resurrected, he decides to have some "fun" with HP before killing him. SS does his best to help but the aftermath is more traumatic than either could have imagined. Can sex/comfort ever truly be love? How much can finding the will to live cost? Sequel link on profile.
