Sterek end
Mates live and die together. When one passes away, the other is bond to follow their mate soon after. This only happens when one of them is killed or has an accident. If not then the mated couples usually live long lives and take their final breath together while sleeping
When both had grown grey and soft, it's time to leave. And Derek is the first to sense the change.
One night he suddenly tells Stiles to take two days off from their usual routine to do whatever they wanted to. They go visit their grandkids, they go to the beach, they eat Stiles' favourite dessert while watching Derek's favorite movie cuddling in the couch. Before they go to sleep that night, Derek cleans the house and steps outside to howl, soft quiet howls answering in the distance.
"What was that one for? Haven't heard you howling in a long time" Stiles asked while getting ready for bed. His movements slow and tired, his strong hands with fragile bones reaching to hug Derek.
"Nothing special, just felt like it"
For some minutes they looked at each other, love reflecting on their faces. Stiles was used to his wolf, he knew something was going on, but if Derek hadn't said something then it was probably not that important
"I love you sourwolf" Stiles murmured before softly kissing Derek. Then he smiled and got comfortable hugging his husband.
When Derek felt Stiles' breath slow with sleep, he smiled and kissed his forehead. His arms holding tightly to the human he had spent his life with.
"I love you Stiles"
Some hours later they took their final breath
Together
