“Come on Lance. I know you've got more than that in you.” A booted toe touched the underside of his engorged prick, pushing it carefully down towards the poor thing's belly. Just a toe too far and a cramping strain traveled up in, enforcing something that balanced right on the line between pain and pleasure. He could see it clear as a bell on Lance's strained expression and Shiro had no compunctions about holding it. “Do it for me, tough guy.”

Lance curled up and watched his cock turn red from anguish. It wasn't a matter of just doing it! On the floor and slipping off his belly were the cooling remains of the previous four climaxes. How many did the man mean to push him towards. It was times like this when Lance seriously considered himself a poor negotiator. But then, Shiro had offered him the opportunity to choose.

“Do you want to tell me how many to go for?”

“Well I could. But where would be the fun in that?”

“Depends on who you want to have fun.” Shiro had kissed him deeply and considered for a moment before that confident leer of possessiveness had shone through his dark eyes. “You could let me pick. Would you be okay with that? Letting me decide how many you can take?”
 
Obviously the answer had been yes. The first one had been easy enough.

Cradled in Shiro's protective grasp, leaning back into his lap while those hands caressed his dick into erection and slowly drew a gentle orgasm from it. What more could he ever have asked for? The second had been just as good, even if it had left him panting hotly and flushed when Shiro had put his mouth deep on lance's cock and milked him with his tongue. Just watching those calm, gorgeous eyes look up at him while sucking him off was visually stunning. How could he do something so simple and make Lance feel so rewarded?

The third required a bit more coaxing. Lance had been grateful when Shiro had bound him up, keeping him from resisting too much or shoving his hands away. They had a safety word. If he really wanted to, he could use it and Shiro would listen. So when the fingers breached his hole, crooking in search of producing a more gratifying stimulation, Lance had just about lost his mind. His prostate was an easy find. Add to that the return of Shiro's fingers around his prick and he'd cum beautifully, squealing in a high voice as another one was pulled from him.   
 
But the fourth? Oh god the fourth was so wonderfully shattering! They were getting into more playful things by that point, and Shiro had been determined to take him time. A plug held him open, preparing him for something larger down the line. Lying on the floor, servile and meek under his touch, Lance had crooned out in tight, whiny gasps when his entire length had vanished down the captain's throat. Every now and again he would nudge the plug and Lance knew he wouldn't be able to hold back from a howl of twisting pleasure. 

Now? Oh he was pretty sure he was gonna die from this one.   
 
Lance peered at the small bullet vibrator attached to his cock, making him strain as it continued to jiggle his sore prick about haphazardly. It had no mercy on him. Really he didn't understand how he was still hard by this point. It didn't help that Shiro was pressing his cock like a gas peddle in traffic, bouncing the poor thing up and down for his own amusement. A tender sob broke free and he grit his teeth, shaking his head before he almost knocked it back on the floor.

“Now we can't have that.” Shiro took his foot off, a brief mercy, and walked over to the bed, bringing back a pillow. He lifted Lance up and placed it under his head, offering a small comfort. “There we go. Better?”

“Y-yy-yes!”   
 
“Excellent. Lets get back to it, shall we?” 

Down came the foot, and Lance howled in desperation. “S-shiro! I can't!”

“I think I know well enough by now how much you can withstand.” He applied more pressure just for the enjoyment of watching Lance cringe and strain not to rub against the rubber sole. 

“S-hiro! Come on! Please? Please.” He gazed up at the hard on trapped by the trousers. “I can take care of you. Aren't you hard by now? Huh?” Lance whimpered as the foot pushed his cock until the tip was up against his belly button. “Ouh fuck! C-c-c-ome on! Please? Please! I'll suck you all the way! Swear!”

“You have a safeword.” Shiro reminded him, clearly more confident in his strength than Lance was. “You know you can use it. You've done so well, Lance. I'm really really proud of you.” He reached down and caressed the chin. Don't you wanna take a few more for me?”

His insides were a pool of molten adoration. Damn him! Shiro knew he was such a sucker for praise! He noticed the man's thumb click down just before the vibrator picked up a notch. Lance arched up high, rolling his hips as he was pressed with damning force into another orgasm, his mouth going dry at it. “Sheeeeeeerooooooo!” 

“I know. I know. You're being such a good boy.” Shiro pulled his foot off, letting the cock bob in the air . He admired Lance's shaking body for a moment, clicking off the vibrator and smiling as he went limp.

“Ho. Ohhhhh fuck. T-thank you. Huuugh.” He should have known better, he really should have! One perfect eyebrow rose and that bastard had the most smug look on his face.

“Well, if you can still form coherent sentences, I'm clearly not done here.” Shiro took a plastic shopping bag from his bedside table and brought it over, pulling out six bullet vibes, each one a different color. “Now, how many times do you think you can cum with all of these in your ass?”
