"You're doing great, babe." Jackson calls out.

"Yeah?" Mark asks, breath hitching from exertion. He inclines forward, just as Jackson leans behind, and rests his chin on the other's shoulder.

"Mmhmm," Jackson hums in confirmation. He presses back further until he meets the elder's front. Mark tightens his arms around Jackson's waist and with a tilt of their heads they slant their lips over each other without stuttering their rhythm. Their tongues dance in tandem with each other and it is Mark who breaks the kiss first to adjust his grip on the younger.

Mark slides his hands down to curl around Jackson's hips and rides even harder, bouncing up and down with renewed vigor. His thigh muscles are screaming in agony and he's covered from head to toe in a sheen of perspiration but he's never felt as much of a thrill as this before.

Jackson digs his heels into the horse's flanks and spurs the animal on into a full gallop. Mark squeals at the burst of speed and clings on tighter, mellifluous peals of laughter resounding like a melody to Jackson's ears. The younger risks a quick turn behind and is rewarded with a blindingly wide smile from Mark that warms him from inside out. "Are you having fun, babe?"

"Yes, yes, yes!" Mark cries in delight, and Jackson feels his heart swell with pride.

Note to self: Bringing Mark to a ranch will be the perfect date idea in the future.
