He Gets Up

Yellow said nothing but deftly climbed to his feet, behind the presenting Red. As he moved forward, pressing his cock between the flesh of the other Buck's buttocks, he felt him tense up. Believing this to be apprehension, Yellow once again gave Red an inquiring look, but his friend just nodded to him resolutely.

Reaching over to the bottle, he began lubricating his shaft. Yellow was familiar with the process and really didn't need as much lube as he put on, but wasn't taking any risks here. Once more, he braced against his friend's ass. Parting his cheeks, Yellow carefully eased his tip against Red's asshole, still not quite believing he was going to be allowed to go through with this.

As he entered him, Red gasped and gritted his teeth, but motioned for Yellow to carry on. The gentle pushing in deeper, Yellow felt his dick squeezed by the insides of his partner, his shaft gripped and pleasurably massaged by the Buck's soft behind. Holding onto Red's hips, Yellow gave a first testing thrust into him. Red gasped again, but this time surprise was mixed too with something else.

Withdrawing back, he swung his hips in harder this time, huffing slightly from the effort. Red grunted. Yellow was gaining confidence with every swing and began groping Red's cheeks, properly moulding them around his shaft. The pair began to pant and moan in a synchronised harmony of ecstasy and exhilaration.

With all his prior doubts dispelled, Yellow was fully engrossed in fucking his friend. His hands wandered, caressing not just Red's rear, but also across his back, his chest, and, of course, his penis. The Buck would be slightly disappointed at a lack of an erection from Red, his stimulation prompting some hardening, but clearly it was him who was most aroused by this event.

The strength of his thrusts had plateaued now, and he was coming to the brink. He slowed down for just a moment and leaned in to fully mount Red, but also to be closer, ensuring he was heard over their panting.

"Gonna... Cum!," He gasped, "Where?"

Red turned to look at him over his shoulder, giving a strained smile, "I'd- Unf! Prefer it- Ah! Not Inside..." He seemed to struggle to get the words out while being impaled by Yellow's member.

Yellow nodded, preparing to finish. He increased his speed briefly, hammering in and out of Red. The other Buck gave a trembling moan, as Yellow finally pulled out. He sighed as he directed his load, the hot, sticky, white liquid shooting over Red's behind and a way up his back. It was a considerable volume of cum that coated the Buck, and it was a few seconds before Yellow's ejaculation finally ceased...
