His prick isn't quite hard yet, but that changes in an instant as Neville leans in and slowly runs his tongue along the underside. The gasp which escapes Charlie’s lips is equal parts surprise and pleasure; it’s been months since he last received a blowjob, and even this first teasing lick feels almost unbearably good.

“Yeah?” Neville asks, his lips pressed against Charlie’s shaft.

“Yeah.”

Neville flashes Charlie a blinding grin, then tilts his head up and runs the very tip of his tongue over Charlie’s slit, tasting the drop of pre-come which has gathered there. The sight of it triggers a rush of arousal so strong Charlie’s knees almost give way, and he moans in frustration when Neville pulls back.

His disappointment is short-lived, though. After a moment’s pause, Neville reaches up to curl his fingers around the base of Charlie’s cock. His firm grip and easy confidence are intoxicating; Charlie’s head is spinning, his body aching for more.

When Neville’s lips close around the head of his prick, Charlie can’t help but buck forward into the searing heat. Neville’s mouth is soft and almost sinfully warm, a stark contrast to the frigid air. He sets a steady rhythm, sucking lightly as he takes Charlie’s cock deeper and deeper with each bob of his head.

In no time at all, Charlie finds himself leaning heavily against the greenhouse wall, choking out a stream of broken praise between ragged breaths.

“Fuck, your mouth … so good, Nev…”

He tangles his fingers in Neville’s blond curls, desperately fighting the urge to take control and fuck his throat raw. The sight is too much to bear; he’ll come in no time if he’s not careful. He throws his head back in an effort to regain some composure, but it doesn’t help.

As he does so, a droplet of water hits his upturned face, interrupting his daze of pleasure. Another one quickly follows. Then another. Within seconds, Charlie and Neville are caught in a torrential downpour.

Before long, Neville’s hair is plastered to his forehead, but he never falters in his movements. He takes Charlie’s cock all the way down into his throat, until his nose is nestled in Charlie’s pubic hair, and holds it there. It takes every last shred of Charlie’s willpower not to thrust hard into Neville’s throat. Just as he’s about to lose control, Neville swallows.

“Oh, fuck!”

His throat flexes around the head of Charlie’s prick, squeezing in the most exquisite way, and Charlie falls apart. It’s too much, too good, too late, he’s reached the point of no return...

“Nev, I’m gonna … I’m—”

Charlie’s warning is lost to the force of his orgasm. It tears through him, a heady buzz of intense pleasure that radiates out from his balls to the very tips of his toes, and for a moment he forgets all about the rain.

Ever the pro, Neville swallows every drop Charlie’s release and continues to suck lightly on the head of his prick until he twitches away, spent and over-sensitive.

Victorious, Neville wipes his mouth with the back of his hand and tucks Charlie’s prick neatly away before getting to his feet. “That was fun,” he grins.

“It was brilliant,” Charlie agrees. “But what about you?”

Neville grimaces. “We’ve probably been gone too long already. Besides,” he adds, struggling to suppress a shiver, “we’ll catch our deaths out here at this rate!” He smiles, suddenly shy. “Maybe you can thank me tomorrow?”

“Definitely. Only I’ll find somewhere to do it indoors…”

With that, Charlie takes Neville’s hand in his and they begin the long, soggy walk back to the castle.
