My Heart, My Thorn

I have signed to be his loyal slave and he my master. I have signed away freedom. What have I done? I have taken off my clothes as he's asked. Am shaking, naked in front of him.
"Lay on the table." He orders. I obey. I don't argue. I can't argue.
"Spread your legs open." His voice, a caress, yet firm. I shakily obey. My legs timidly spread before him. The cold air drifts to me.
"Now, Andria, touch yourself. Touch yourself until you moan."
I look at him shocked. I have never done that before...
"Do you want to rescind on your decision?" He asks, darkly...
I swallow. I don't want to. My body tenses, but I ease it. I shut my eyes. Allow his voice carry me, as one finger tentatively slides into my dark underwear.
Slow. Shaky. I apply soft strokes...circles. I touch my folds. I let out a moan..
