Walking towards possible death or a wider sky.
I knew that having cum so recently I was going to last a good long time, which was exactly what I wanted. The way she was manipulating my balls was turning me on faster than I expected however.
After quite a while I was starting to approach my orgasm. It was building up slowly still and I could tell it was going to be good and intense. I considered placing my hands on her head so she didn't pull off when I started cumming, but decided to see what she'd do of her own volition. The pressure had built to the point where I could hold back no longer. I started to pulse jet after jet of cum in her mouth. To my great pleasure she stuck with it, sucking and swallowing as much as she could while I continued to cum.
When the spasms subsided she finally let my cock slip out of her mouth and with a big smile looked up at me, licked her lips provocatively and made an exaggerated swallowing motion. She hadn't been quite able to contain the full load and a small stream of cum had run out of both corners of her mouth and down her chin, dripping on her large tits. It was a very sexy sight.
I just laid back and closed my eyes, breathing hard. She got up and headed to the bath to clean up. It was several minutes before she returned. She had a big smile. She crawled up on the couch next to me and wrapped her arms around me, laid her head on my shoulder and just sort of, well, purred. She seemed quite pleased with herself.
She just sat there holding me while my breathing returned to normal and my pulse slowed.
Finally after allowing me to recover a long while she spoke, whispering in my ear, "Do I get to cum now?"
"You thought you were that good, huh?" I teased.
"What did you think?" she cooed.
"It wasn't too bad" I said as deadpan as I could.
She playfully slugged me in the arm, "Not good enough you'd want more huh?"
I couldn't help chuckling, "I didn't say that!"
"Then it's my turn to cum, PLEASE Scott!" the desperation showing in her voice.
Still teasing I said, "Well, it was good enough to earn you the chance to cum."
She tensed slightly at the word 'chance' figuring there was a catch.
"What do you mean?" she asked warily.
"Come on, I'll show you" was my noncommittal reply.
I led her over to near where I had a hanging plant suspended from a hook in the ceiling.
"Wait here" I instructed.
I returned shortly with a pair of wrist cuffs that each had a rope attached. I also had a spreader bar that had ankle cuffs attached to each end.
Without explaining what I intended, I removed the plant from the hook and set it aside. I attached the cuffs to her wrists and raised her hands over her head. I then tied loops in the two ropes and adjusted the length until I could hook the loop over the plant hook. At this point she was standing there flat footed with her arms over her head, but not really stretched.
The sight of those huge tits, with her arms straight up, was awesome!
Next I inched her legs apart until the spreader bar would fit between them. I then attached it, using the cuffs, to her ankles. When I'd spread her legs it lowered her just enough so that her arms were now pulled tight, though her feet were still flat on the floor. Not so tight as to be uncomfortable, but she couldn't move much. Some, but not much, which was exactly what I wanted!
It was time to explain.
"Okay, here's the deal. First I'm going to stimulate your cunt for a while, then I'm going to stimulate your tits. Simple as that. I'll keep going back and forth until you either cum or ask me to stop. You don't have to use your safe word, just tell me you want me to stop and I will and then our little game will be over. As long as you choose to keep going, every time I alternate between your cunt and your tits I'll do a longer, stronger stimulation than the time before. Got it?" I asked in conclusion.
By now she knew enough to be suspicious, but just nodded.
I began fingering her pussy, avoiding much direct contact with her clit.
