Force him to cum on his own face
From Create Your Own Story
You lift his legs in the air and arch his body backwards so that his cock is pointing at his face.
"Ready to cum, slave?" you whisper. He frantically nods as you start smoothly stroking his twitching pole.
"Open that pretty little mouth of yours," you purr. He obligingly opens up, and you speed the motion of your hand on his cock. Jets of hot, sticky cum burst forth. Some of it lands in his mouth, but most of it ends up on his face and neck. You make him swallow, then clean him with a wet sponge.
He looks completely drained and somewhat dazed. "Need a little rest, slave?" you murmur.
"Yes, please... Mistress."
You both perform a needed function, then you bind his wrists and lie him on the bed, holding him from behind. He closes his eyes and sleeps for about an hour.
When he starts to stir, you nibble on his neck, making him shiver.
