(Adapted from an RP--I was playing Will~)
They leave as the sun is rising and hike steadily through the morning, first through tall conifer forests, and then alpine meadows carpeted in flowers, and eventually across shattered talus slopes. Will glances back at his friend, whose face is tilted down as he pays attention to his footing on the uneven trail, his red hair slightly damp against his neck with exertion.
Will had been thinking of doing this trip for a while, and on a whim had invited Ares to come along. The speed with which he had agreed to a backpacking trip of a few nights with only the two of them made Will hopeful that Ares might also be interested in a bit more than just a chance to swim in a pristine alpine lake.
In the early afternoon they stop to eat and take a break, but they are getting close to their destination, so they soon press on. At last they come over a shoulder and see the lake in a pocket below them, nestled among dwarfed alpine trees, a blue-green so vibrant it almost seems to glow. Compared to the sweltering bare slope where they are standing, it looks like a cool oasis.
They head down the trail towards it, still a mile or so off, the incline steeply downhill for the first time all day. When they at last reach the lake, they are both sweaty and covered in dust. The trail has come down to a bluff overlooking the area, and the startlingly-blue water gleams like a jewel some twenty feet below them. It is so clear that they can see all the way to the bottom--even though it must be at least thirty feet deep. It is only in the middle of the lake that the water becomes deep enough that the lake bed is lost from view in opaque cobalt blue.
The trail continues about a half mile around the end of the lake to a low meadow on the far side, with easier access to the water. But Will doesn't want to wait. "Dare you to jump from here!" he says, and when Ares looks over, Will is already skinning off his sweaty shirt.
"Okay bro!" Ares drops his pack, quickly looking around to double check they are alone. Then, to Will's surprise, Ares pulls down his pants and boxers in one motion, revealing the smooth skin of his ass and his shaved cock and balls.
"I see you still have your pants on," Ares says, shaking his hips and making his cock bounce. "Stop staring and get naked!" Then he runs and jumps off the cliff.
Will fumbles at the button of his pants, freeing himself from them as he hurries after his friend, leaving a trail of crumpled clothes and hiking boots in his wake. There is a brief but stomach-clenching fall into the void, then he hits with a large splash and plunges deep into the crystal clear water with a sudden refreshing shock. Will strokes upward, shaking water from his dark hair as he surfaces.
"Ohh, it's so good!" Ares says as he floats in the cool water, resting his muscles from the long hike. He rolls over and dips underwater, his pale ass surfacing briefly before disappearing, and Will suddenly feels exposed, treading water naked in this perfectly-clear lake with Ares underneath the surface, surely able to see everything. He can feel his cock slowly stiffening, which is strange considering how cool the water is, but perhaps it's just the thought of Ares looking at him.
Ares still has not come up, and Will finally can't stand it anymore and ducks under the surface himself. Underwater, it feels like he's floating in air, every rock on the bottom thirty feet below clear as day. And as he suspected, that is not the only thing clear as day as he looks to where Ares is treading water, apparently having surfaced just as he ducked down. Will can see that he is not the only one getting erect, Ares' dick standing up between his legs below the smooth curves of his abs.
Will feels a sudden urge to get his hands on Ares' body, but he's not yet sure how he would react. But then he grins mischievously and darts forward, wrapping both his hands around one of his friend's ankles and pulling him suddenly under the surface with him.
Ares' surprised face comes into view, trailing bubbles, and he waves his arms and free leg, trying to orient himself. His motions bring them closer together, almost hugging, and a sudden jolt shoots through Will as he feels the warm brush of his dick against Ares' thigh. Ares' eyes widen, then he grins impishly as he reaches down, casually rubbing his fingers along the tip of Will's cock. It gives a throb against his hand, hardening, and Will gasps, losing all his air in a rush of bubbles. Ares' smile deepens, but then he puts his foot on Will's thigh and uses it to push himself back to the surface.
A couple seconds later Will splashes up next to him gasping. He sees Ares grinning playfully at him, and realizes that he had no reason to be shy. He puts on a serious face and swims closer to him, meeting Ares' gaze with a challenge in his eyes; he almost looks like he wants to fight. But as he comes into his space, he suddenly grabs the back of Ares' neck with one hand and pulls him forward for a kiss, tongue pushing against his parting lips. Ares' arms wrap around him and bring him closer, their cocks nudging against each other's stomachs. However, not enough of their limbs are being used to keep them afloat, and their heads accidentally sink beneath the water again, still kissing.
Breaking the kiss, they kick back up. "Let's move to shallower water," Ares pants, and strikes off toward shore. They choose a place where a submerged boulder forms a shallow depression almost like a hammock near the surface, one side out of the water. Laying side by side in the sun-warmed water, small ripples lap against their bodies as Ares leans over and kisses Will, his hand reaching down to play with his dick, slowly jerking it. Will's breath hitches, and he pushes up more firmly into the kiss.
"You chose such a nice place for a hike," Ares says, caressing Will's cheek with the back of his hand. "I'm so happy we're here alone.
Will looks up at him and smiles. "I'm really glad you accepted my invitation," he replies, enjoying how comfortable it feels to lay in the rippling waters of the shallows after the heavy exertion of the morning, the smooth stone under his body and Ares' hand teasing his increasingly-hard cock.
He raises himself up slightly, leaning in to bite Ares' bottom lip as his hand slips down to wrap around his shaft in turn, thumb playing lightly across the sensitive head. Will scissors his legs slightly to stay in position, and feels a long strand of water weed wrap around his ankle. He flutters his leg free absently, focused on more important things.
Ares moans lightly, mouth open against Will's, and Will feels a warm little ooze of precum against his thumb, more viscous than water, as Ares grabs him and pulls him into a deeper kiss. Will is vaguely aware of more weed curving over his wrist in the lapping wavelets, wrapping loosely around Ares' cock, almost as though seeking the source of the precum, but he is too distracted to care much, even beginning to enjoy the slippery feel of it sliding over their entwined bodies.
Ares rolls over so that he is on top, pushing Will down against the stone as they keep kissing, the weed tangling between their legs. Will feels Ares' smooth arm snake around his waist, and then it tightens suddenly, pulling him abruptly up against his body. Will grunts at the impact, but Ares keeps squeezing harder.
"Ares," Will says, his voice strained, "that's too tight!" His eyes snap open as he feels himself begin to rise from the water, and to his utter confusion sees that it is not Ares' arm at all around his waist, but a thick, dark blue-green tentacle encircling both of them! He gasps in shock and struggles, trying to push it away with his hands, but its grip is too tight. His motions slide his slick, wet skin against Ares', as they are tightly pressed together in the same muscular loop. Smaller, slippery things are wrapping around their arms and legs, and Will realizes that what he had been assuming were water weeds are actually smaller tentacles!
