A/N: I must credit Fuckyeahsaiyanyaoi for the idea of the “more creative use” of ki rings!
Vegeta all but collapsed into bed with Kakarot. His heat cycle was torturing him cruelly, and, he had to admit, he missed him. Despite his heated coupling with Goten, his state had worsened. Kakarot could sense it, his arms closing tightly around him, his lips crushing passionately to his own. With a strangled moan of desperation Vegeta held him tightly against him, his legs wrapping around him as he pulled him atop him. Arching his back, Vegeta kissed him heatedly, feeling Kakarot’s lips descend to his neck and practically devouring him.
“Kakarot…” His breathing was already heavy. His tongue traced the contour of his ear before teasingly biting it and whispering, “Take me… now.”
“Calm down, Geta,” Kakarot said with an amused smile, stroking his hair, “Where’s the fire?”
“You know where,” Vegeta groaned, his hands sliding down to Kakarot’s muscular ass. Squeezing him hard, he pressed him just as hard against him. Kakarot’s hand slid between Vegeta’s legs with an approving moan at Vegeta’s extreme hardness.
“My poor Geta, you need me, don’t you?” Kakarot purred gently, stroking him knowingly.
“Oh! Gods… Kakarot! I can’t stand this heat cycle. It’s driving me… insane!” His teeth sunk into Kakarot’s neck, barely aware of the fire he was stoking in him. He had felt an alarming change in his ki, but was truly too hot to take notice. He felt Kakarot removing his pyjamas and was about to do the same when Kakarot told him, “No… you first.”
Too hot to argue, Vegeta kissed him passionately, his tongue moving teasingly between his lips, knowing the effect it had on him. He should not have done so.
Before he knew what to expect, Kakarot sent forth not four ki rings, but seven. Four of them retained his wrists and ankles spread out on the bed, and the others served as tight rings at the bases of his arousal, his balls, and his tail.
Kakarot’s regard had darkened to reveal an expression that Vegeta had never seen on him before, not even during his worst combats. He looked evil.
“Kakarot,” Vegeta protested, dismayed at the trembling in his voice, “Cut it out, this isn’t funny!”
Kakarot’s hand and lips descended to his neck, to his chest, to his nipples, which tightened painfully, slowly down his body without missing a single sensitive point.
“Don’t do this!” he protested again, but Kakarot ignored him, arriving at his inner thighs, approaching just close enough to where he needed this contact before moving away again.
“No,” Vegeta protested, pulling hard but uselessly against the rings. “Stop it, I mean it!”
He was rewarded with a small, mocking laugh, and was just about to scream the safeword when he felt Kakarot’s tongue lash him over his balls, up the underside of his pulsing arousal, then over his darkened, leaking tip.
“A..ah… uhn!” Vegeta’s hips arched against this welcome contact, almost screaming when he abruptly stopped. “Kakarot, stop it! I… really… can’t!”
“Vegeta,” Kakarot purred, his tongue licking his ear softly, drawing from him an involuntary shudder, “You wouldn’t disappoint me, now, would you?”
“If you don’t stop, I swear I’ll use the safeword!” Vegeta said, and meaning it. He didn’t at all like his look, nor the strange vibrations of his ki. He wasn’t at all normal. “I can’t be teased now. I really can’t.”
“Really?” Kakarot said, amused. He directed his hand, and the ki rings holding his intimate parts began to pulsate. His hips arched involuntarily and he cried out silently at this excruciating invasion… so painful it made his yearning, yet so wonderful at the same time. He couldn’t deny anymore the intense pleasure this brought him, but not now. He couldn’t take it right now…
