Kate smiled sweetly at him as she stroked him just the way he had always liked. Don gripped the edge of his seat so hard his knuckles went white. He grit his teeth and tried desperately not to moan.
"There's no use trying to hide it, hon," said Kate. "You're not going to trick me into getting you off. I have super senses and super speed perception. I can tell to the millisecond when you're about to blow your load. I know just where to touch, just when to stop and start."
Kate's hands worked their magic, gently kneading his swollen testicles and stroking his iron hard penis first quickly, then slowly, the quickly again. She would occasionally pause to give his shaft quick, rhythmic squeezes, clenching the muscles in a way that mimicked his orgasmic spasms, which caused his body to immediately try and ejaculate. But just before he could, she would cut him off, digging her thumb into the spot just below his penis head, and squeezing around the base of him. The split second his orgasm started to fade, she would resume her strokes. In this way, she kept him riding the fine edge of climax, but never let him go over.
Don let out a suddering gasp. "Kate... please... please let me cum... please don't... please don't tease me like this!"
"Nope," said Kate. She laughed as he failed to fight back a groan. "Shhh... remember sweetie, not too loud. Don't want to alert the neighbors, after all." Don's eyes went wide as he remembered they were still on his apartment's balcony. It was late in the evening and the balcony lights were turned off, but he would be visible enough if one of his neighbors decided to see what the commotion was about. He looked around to make sure no one had spotted them. Kate took advantage of this distraction to kiss his penis gently, providing just enough suction to trigger his climax before she pinched it off yet again.
"Kaaaaaatte..." he gasped. "Pleeeease..."
Kate let go of him and looked around. She smirked, then in the blink of an eye, dashed into the house, rummaged through his stuff, then dashed back. Don didn't even have time to register the absence of her hand before it was back, stroking slowly again, dragging precisely along every sensitive nerve. She held up a golf ball for him to see.
"Now, Don, please pay attention," she said. "I warned you that I don't want you to cum unless I say so. You have a lot of catching up to do for me, Don. All those times we had sex and I was left unsatisfied... every time you came, stroking off to one of my pictures. I've decided every orgasm you had at my expense equals a full week without orgasm. If you're really nice to me Don, I might give you a freebee now and then, but don't hold your breath."
"God... not fair... Kate... no fair..." said Don. He looked longingly at his penis, her powerful hand touching him firmly, but gently, her face so temptingly close to his crotch. He wanted more than anything to grab her head and push her mouth onto his cock and fuck her mouth until she was nearly choking on his cum. The bitch deserved that much by now, he thought to himself.
"Well, hon, you're in no position to decide that," said Kate. "I'm a superhero now. I've got power you couldn't even dream of. And if you're good, I'll watch out for you, I'll take care of you. But if you're bad, I will punish you. As far as you are considered, I am the law. And by my law, your penis is now my toy, and you are now nothing more than my plaything." She brought the golf ball into view. "Now, Don, watch closely. I want to show you what will happen if you don't do as I say."
Don watched as she held the golfball in between her thumb and forefinger. He jumped as, with a simple, effortless squeeze, she cracked it in two. The two halves started to fall away, but she caught them instantly, held the halves out in her open palm. Then she closed her hand and made another effortless squeeze. Don broke out in sweat and his eyes went wide as a loud cracking and crunching sound was heard. Kate opened her hand and turned it slightly, dumping a small pile of dust into the evening breeze.
