Not much happened between then and lunch. I had imagined that I'd be trying to fuck every girl in the school, but after the first bit of fun I'd had, I was pretty drained.
At lunch, however, I saw an ass I just couldn't resist, and checked her hand.
Sure enough, she had the little stamp.
"I challenge you." I said, "What game?"
She turned away from me, and tried to run.
I grabbed her by the arm. "Ah. The "Run away and hope you don't catch me and make me your sex slave game."
I dragged her by the arm through the crowd of students, many of whom were smiling, as she kicked and tried to escape me. After a few minutes of back and forth struggle, I pulled her into one of the private rooms.
"Do you know what the penalty for trying to escape playing a game is?" I asked, my cock rock-hard in anticipation.
She nodded.
"Tell me what it is." I smiled.
"You get to make me your sex slave." She muttered.
"That's right. How long can I keep you for?"
She looked away from me, and refused to answer.
I slapped her. "Answer the fucking question."
"The rest of my life." She muttered, a tear rolling down her face.
"Good fucktoy. You're now officially my sex slave. For the rest of your little fucking life." I said, touching the back of my hand to the back of hers. Her stamp changed, now saying 'owned'.
She didn't respond. I forced her down to her knees, unzipped my pants, pulled my cock out of my boxers, and said, "Suck it."
