"Come back to mine and I'll give you the best blowjob you've ever had."
I looked round to the girl who had just who whispered this in my ear. She was quite big, about 250lbs, dressed sexily with pretty makeup but still a fattie. I hesitated, as big girls aren't really my thing, and she raised her eyebrows as if to say "Well?!" I gathered a blowjob is a blowjob and there wasn't exactly much else in the club so I stood up. She smiled, took my hand and led me out.
The walk lasted ten minutes and was in complete silence. Once we reached her flat she opened the door, motioned for me to go in, followed behind and shut the door. She again took my hand and led me to her bedroom where there was a chair. I sat down and she leant in front and passionately kissed me. Her hand reached down to my jeans and felt my rapidly hardening cock. She undid my jeans and held my penis through my boxers.
"You have to wear these." She produced a pair of handcuffs and restrained my wrists behind the chair, making it clear it was a statement rather than a question.
She then peeled off my boxers and started to slowly rub my penis, wanking it off. She stopped to take her top off, exposing her bra to me, and resumed fondling me.
"You like?"
I nodded and she smiled. We exchanged tongues again and she held my cock. Then she removed her bra and starting tit wanking me with her huge bosoms. The feeling was amazing and I wasn't regretting at all taking the offer from this big girl.
A few minutes later she pulled away, reaching for something under the bed. "Now I'll put this on you and suck you off." She placed a blindfold over my eyes and took my cock in her mouth.
It began slowly then gradually got faster and harder. Easily as good as any I'd had before, her tongue working my dick wonderfully. I was close to orgasm when she suddenly stopped.
"If you want to cum this penis becomes mine. I will lock it in a chastity cage and decide when and if you orgasm. If you can resist the urge for five minutes I'll let you go."
As I pondered this scenario she held my erect penis with one hand and my right thigh in the other. I was begging for release, my hands straining against the handcuffs. I didn't want my cock controlled by this bitch but my desperation to climax was overwhelming. It was too much and I gave in.
"Let me cum!"
