The following weeks did indeed demonstrate a change. Josh spent as much time as he was able at David's, going around after work and staying on the weekends. It was summer, and the weather was quite warm. It quickly became routine for Josh to take his clothes off as soon as he entered the house, with David following soon afterwards. Sometimes they would fuck straight away, but often they would just go about the evening, happily naked and enjoying each other's company. Thankfully aside from a small guest room at the front of the house, David's windows all looked out onto a contained backyard, so no one could observe their naturist tendencies.
For Josh, this was a new awakening. They were still the best of mates, knocking back beers, watching the TV and joking about the standard guy bullshit that had formed their relationship over the years. The newfound physical intimacy, though, was an extra layer that neither of them had ever anticipated.
Josh had always liked being naked. When he was home alone, he'd always been quick to get his kit off. He'd once been found vacuuming naked by his housemate who had finished work early. Josh hadn't heard the door opening over the noisy machine, and by the time he noticed that he wasn't alone, the housemate was in fits of laughter, holding himself up against the doorframe. He still blushed just thinking of it.
David quickly grew accustomed to it as well. David had given him a spare key, and more than once he'd come home to find David going about some chore or other, naked as the day he was born, birdsong drifting in through the open windows. Josh was amazed at the degree of attraction he felt towards David's body. He had obviously seen other naked guys in change rooms, etc. but that had always been a furtive glance, never really paying attention to what they looked like. Now, he would find himself just ogling him unashamedly as David stood or sat next to him naked.
They were both uncut, but David's foreskin seemed longer, the redundant tip dangling slightly over the end of his cock when it was soft. His balls hung looser too, like large weighty nuggets inside the loose, trimmed sac. He was intrigued by the way his junk moved as he walked, and by the way his balls lolled around as he sat on the couch. Of course, his own package did all of these things, but it was somehow different watching from this angle.
David would often notice him watching, and with a smile, would generally play up to him, whipping his cock around in a helicopter or walking over and slapping him across the face with his flaccid dick. Often though, Josh's voyeuristic habits would result in his own cock hardening, and naked as he was, this was impossible to hide. Invariably this would be noticed almost immediately by David, who would quickly dive on him and start sucking on his cock like his life depended on it.
One evening in particular stood out in Josh's mind over those first fuck-filled weeks. He had just finished cleaning up after the dinner that David had cooked, and walked into the loungeroom to see David sitting naked in an armchair, legs spread, hard cock in his hand. He stood by the doorway for a minute or so, watching him stroke his cock. David saw him, and locked eyes with him as he stroked himself back and forth, rubbing his smooth foreskin over the glistening head of his cock. Rather than walking over and burying his face in David's crotch, he grabbed his own growing erection firmly and sat down in the chair directly opposite him.
Facing each other, legs spread, they locked eyes and stroked slowly, pleasuring themselves and putting on a display at the same time. Josh was as turned on as he'd ever been. There was an intensity to the sensation, different to when they fucked. It was somewhere akin to a voyeuristic pleasure, feeling somehow involved in David's pleasure, but also somehow guilty for watching him.
His cock leaked into his hand like a faucet, the smooth precum rapidly lubing up the head of his cock. With his free hand, he reached down and started playing with his hole, looping one leg over the arm of the chair to get better access. David watched him for only a second before adopting the mirrored position himself and beginning to explore his own hole. Intrigued, he watched as David started to match his actions stroke for stroke, circling his hole with one finger just as Josh was.
Testing the limits of his new-found remote-control power, Josh wiped some of his copious precum on the middle finger of his left hand, smiling as David did the same. Returning to the cleft of his arse, he wiped some of the self-made lube around his hole, slowly and sensuously. David matched him move for move.
Rapt, he watched as David was guided through his first anal exploration, the tip of his finger resting with gentle pressure over the opening of his arse, the pressure slowly increasing until finally the muscle relaxed and almost sucked the finger deep inside of him. Feeling the tight tunnel wrap firmly around his own finger, Josh could see the same sensations echoing in David's eyes only for him this was the first time. He held his finger still, just after entry, allowing David time to accommodate, before slowly sliding all the way in to the hilt. For him the burn was no longer there when his arse was entered, but he knew David would be feeling the tight hole opening for the first time.
Not knowing how else to demonstrate, he slid his finger out again, holding it out to David and showing him the beckoning motion he knew would help him find a new source of pleasure. Sliding back inside himself, he curved his finger upwards in the same way as he slid out again, sliding gently across the sensitive prostate gland. The sudden bliss on David's face showed him that he was feeling the same waves of pleasure through his body as Josh was.
Distracted by the incredible sensation, David lost concentration on mirroring Josh's actions. Wanting to continue to share the experience of pleasure, Josh took to mirroring him instead. Slowly David increased the speed of his strokes as his arse accommodated the finger more easily. Before long, they were both slamming their knuckles hard against their arse, stroking their G-spot faster and faster. David slowed to a stop, and then brought his index finger up to join his middle finger. Josh followed suit as he slowly slid the second finger into his now relaxing hole.
With the increased pressure inside him, Josh began to feel the glow build in his pelvis. Watching David, he was relieved to see the same thing happening to him. With two fingers buried deep and stroking their prostates, David and Josh both turned their attention back to their cocks. Their stroking took on a new intensity now, as they both approached orgasm.
Amazed to find that they had synchronised their breathing, Josh heard the moans coming from both of them as they built closer and closer. With a simultaneous cry, their cum spurted forth, spraying over their chests and even up to their chin. Fingers pushed knuckle deep, they came together, shouting and panting as the climax swept over them and the cum drained from their balls.
Breathing finally slowing down, they slid their fingers out, dropping their foot back down to the floor. Licking the cum from his hand, Josh smiled wordlessly at David across the room, red faced and still panting. David's hand still rested down under his balls, as he stared blankly into the distance, breathing finally slowing. The stunned look on his face told the story of someone who had discovered a new pleasure. Walking over to him, Josh leaned down and licked the cum from his chin, kissing him deeply and sharing the taste. He patted him on the cheek, and walked past him into the shower, knowing that David would be there to join him in no time.
If Josh thought that this new anal awakening of David's would feature in future fuck sessions, he was sorely disappointed. Repeatedly over the coming days he would try to introduce some arse play while he was going down on David, but invariably David would shift positions, often rolling him over and slipping into Josh's arse almost immediately. Josh didn't mind; he still loved getting fucked. He was having the best sex of his life without a hint of a doubt. That being said though, he did wonder what it would be like to take David's virginity one of these days.
