He continued to work the toy as his lips moved lower, ghosting over Marcel's chest, coming near but easily missing the soft nubs, teasing him a while before he finally took one between his lips. His hips moved against Marcel, but a few minutes later he slowed down and pulled away He slid the toy out and turned it off for the time being before stroking Marcel's length. He reached for the beads with a cold smile, "Let's test your self control." He said as he took Marcel's hand and pulled the boy to his feet as he fell back into the chair. "Sit on my lap, facing me." he said, his own arousal resting against his stomach as he toyed with the beads. "We're going to play a little game. I'm going to play with you, and if you're good, I'll let you cum. But if you make a single sound..." He traced a finger up Marcel's length, "I'll leave you like this until morning. And if you cum before I tell you..." He grinned, "Well, you'll see what happens then." He placed a light kiss on Marcel's cheek, against the red mark he'd made, "If you can control yourself, you'll be rewarded."
