The first bead was small and went in easy. Dean's hole sucked it up tight, winking at the intrusion. The second was larger but still slid in easy- no wider than Sam's index finger, blue silicone a bright contrast against Dean's pink hole.

The third and fourth beads had Dean breathing heavy and clenching his hands on the bathroom counter. His face, in the mirror, was flushed, lashes swept dark against his cheekbones.

The fifth bead was where they started getting big- each over an inch in diameter, with the ninth, last ball just over two inches all across. Number six took a bit of pressure and Dean let out a long, low moan when it popped past the rim of his asshole. Number seven didn't want to go in- Dean's channel was stuffed full already, almost out of room. Sam was just going to have to make some more for himself.

Sam pressed the bead into Dean's body, keeping the pressure up until the tight ring of Dean's hole made it past the midway point and closed around the sphere. The other beads had been sucked up inside of Dean at this point, invisible but for the silicone thread linking them all. Number seven was drawn in, but didn't disappear- Dean's hole tried to close around it and failed, leaving a small curve of blue visible within his ass. If the ball had been any smaller, it would have popped back out again.

Dean's hole spread wider around his fingers when he pushed the ball further in until Dean's sphincter was clenched on his fingers, the ball pressed past the tight ring of muscle and nestled inside with the others, tight and snug.

The eighth bead, forced flush against Dean's entrance by the seventh's passage, was wide- wider than Sam's cock and that was saying something. Sam reapplied a bit of lube to the ring of Dean's ass; it was relaxed to the touch, either stretched by Sam's attentions or exhausted after being forced to open repeatedly.

Sam smiled and started to push the wide ball inside. "We're almost at the last one, Dean." Sam kissed Dean's knee, conveniently close. "Touch yourself- it'll make this easier."

Dean's eyes were locked on Sam, on what Sam was doing between his legs. He brought his right hand up, shaky, and took hold of his cock, jerking it with rough, fast motions. He slowed at a sharp look from Sam, reluctant.

"Can't have you coming too soon," Sam said, more to himself than to Dean. He kept the pressure strong on the bead and frowned when Dean's ass opened but wouldn't take the ball, no matter how he twisted it. He let up on the pressure and started thrusting the bead in, rocking it in to ease Dean's body into opening up further.

The bead sank in, almost to the half-way point, and out again- Dean's rim spread open , then shrank again every time the bead withdrew, obscene little squelching sounds accompanying the motion. When he added an extra bit of force, the ball sank in- and out again when Dean's body clamped down, cock spurting all over his hand.

Sam drew back. "That was unexpected," he said, raising his eyes at Dean.

Dean panted above him, looking rumpled, freshly fucked. "Yeah," he breathed out. His ass winked open and closed, the last shudders of orgasm rocking his body.

"I didn't give you permission to come," he pointed out. Sam took hold of the ring at the end of the beads and tugged. He enjoyed the sight of Dean's ass bulging out, the rim too tight to give up what it had taken in at the light pressure.

"'Didn't mean to come, Sammy," Dean muttered and gasped at the pressure on his over-stimulated prostate.

"That's no excuse, Dean- you should have told me you were close." With a strong, firm pull, Sam pulled the remaining beads out of Dean's body. He offered them to Dean to clean, pleased when Dean sucked the first of the beads into his mouth.

"We'll have to start again," Sam said, eyes intent on Dean- on his brother licking up the taste of his own ass. "And you won't be allowed to touch your cock until I can trust you to be honest with me."

A stream of Sam's come oozed out from Dean's ass, from where Sam had stretched him out before.

It was going to be a long day.
