The first time Eren enjoyed it. The rough kisses and the harsh bites and the calloused hands that ran up and down his body feeling every inch of his feverish skin. He was in heaven and never wanted the night to end.
But nothing is the same twice.

The second time lacked emotion; was lust and need instead of love and want.
Rivaille was rougher and faster and less caring. Eren noticed, but went along for the ride, his heart shattering as the older got up and left immediately.

Soon every encounter became a hurried affair devoid of emotion. And no matter how much Eren hated it he could never deny Rivaille. Because every time the man moaned his name or kissed him in a gentle manner Eren believed that the Corporal loved him or would grow to love him. Every caress and chaste kiss would cause the hope to grow before crumbling down when Rivaille left.
Eren wished Lance Corporal Rivaille would love him, just like the brunette lived the shorter male. But he knew his death would come before love and that Rivaille would never love him back.
This was written before I found out that Rivaille is actually a captain rather than lance corporal but as lance corporal sounds better (to me at least) in this story I decided to leave it
