I was already deeply regretting how easily I had followed her lead. Now here I was, standing up against the wall, my hands secured tightly into metal cuffs. She looked me up and down, obviously feeling clever.

“So, you comfortable?”, she asked.
I scoffed. “Hardly”.
She let out a soft hum. I stared at her breasts and felt my cock grow hard. She sank to her knees and took me in her mouth.
I felt a reluctant “Aah”-sound force itself from me as her tongue rubbed against the tip. She used her hand to stroke me. I was already so far gone.

She continued with her hand while looking up at me. “Don’t come”, she said. She sounded almost threatening.
“What? Why not?”
A naughty grin spread across her face. She took me back in her mouth and sucked. Hard.
I let out a yelp and felt that I would not be able to control myself for very long.
“What if I do come?”, I asked.
“Then… you’ll be really sorry that you did”, she said.
I didn’t know what that meant but I felt it would ruin the moment if I asked. What she was doing felt so good.

Luckily, I have excellent self-control when it comes to sex, so I tried to relax my muscles and think of other things. This usually worked very well for me – I had once fucked a girl for a good 10 minutes in a rather punishing rythm without coming, just so she could get hers. However, it seemed I had overestimated myself, because I quickly noticed that my technique wasn’t working as well as usual.
