Her grip tightens on your wrists, her free hand moving lower, rubbing against your aching length through the slickness left behind by her saliva. "Naughty boy," she teases, her fingers moving faster. "I said 'yes', didn't I?" She leans forward, nipping at your earlobe, sending shivers down your spine.

Your body tenses as you feel yourself about to cum, but just before you lose control, she eases up, pulling away and looking at you with a smile.

"It seems you need more training," she chuckles, sliding down your body to take one of your balls into her mouth. Her tongue flicks it gently while her right hand continues to work your shaft. "Today, you'll learn to enjoy being helpless and in my control." The rhythm of her hands increases, both on your cock and ball.

She looks up at you, grinning devilishly. "When I say 'yes', cum for me."
