Version 1
"Please," his master whispered to him. "Don't be gentle with me."
It's an awful thing to ask. But Croquet always obeys.
He slides a hand down his master's slick stomach, feeling the warm flesh twitch with nervousness under his touch. His master's eye is open but it's focused on the roof, and although he tries to smile Croquet can see the fear in that amber orb, and it hurts him to hear his master whimper as he takes hold of his slender, trembling thighs.
But Croquet doesn't stop. Tomorrow, he will spend some time in the dungeons, wallowing in his own shame while his master is struggling to keep a fake smile on his face, and in the evening the cycle will being again.
For now, he will only have to pretend that he is doing this unwillingly. Even if it hurts like hell.
Version 2
"Please," comes a whisper. "Don't be gentle with me."
That is all his master ever says during their sessions, and it hurts like hell to obey.
And it hurts him to feel his master tremble beneath his touch as he runs his hands down his master's lean, slick body, watch his master avoid his gaze by staring at the roof instead of him, the single healthy eye glimmering with fear, hear the scared whimpers hitch in his master's throat, desperate not to be heard. And when he leans down to place his lips on his master's chest, right where the heart beats, he can taste his master's horror through every beat of his heart.
They will not look each other in the eye tomorrow.
