I had no doubts. If I was going to do this with anyone, it would only be with him.
Justin was the only person who came to mind.
A friend of mine, who sometimes promotes new erotic products, wrote to me with an unusual proposal. She had six different lubes to test: one for masturbation, a flavored one for oral, a third for rimming, then an anal relax version, something for intense penetration, and one special formula "for the active." She asked for a specific opinion, but not one like "it spreads nicely on your hands." She needed a review under... realistic conditions. On the body. With use.
I've always been into testing things on others. I liked to feel, observe, evaluate, lead. The touch, the reactions, the changes in breathing, how the body tenses or relaxes.
There was one problem: I needed a body. One I could trust. One that wouldn't get scared.
Justin was straight, but... different. Too easygoing for a typical guy. He made weird jokes, as if he was testing how far he could go. I'd known him for years. We laughed at the same things, talked about everything, slept on the same couch during trips, saw each other naked more than once.
So when he walked into my apartment that evening and sat down on the couch, I just... told him.
"Listen," I began calmly, sitting down next to him. "I have an unusual request. It's about testing. Lube. Touch. Reactions. I need... someone I can test them on."
Justin looked at me with a raised eyebrow, as if he didn't know whether to laugh or run away.
"Wait, seriously? You want to put lube on me?"
I smiled slightly, completely calm.
"You're the only one I would ask. Because I know you won't judge. And you won't run away."
There was silence. I could feel my heart beating. His gaze became more serious. He stared at me, then suddenly burst out laughing.
"Okay. You're fucked up... but why not. Let's do it."
In that one moment, everything changed. I felt excitement, tension... and something that resembled relief.
I could begin.
Justin got up from the couch and stretched as if it were just a Wednesday evening and not the beginning of something that would completely blur the boundaries between us.
"All right," he said sarcastically and took off his T-shirt in one motion.
I watched. Without a hint of shame.
His chest, broad, smooth, tanned. His stomach, clear muscle lines, as if he had just come back from the gym. His nipples tense, his shoulders relaxed.
Then he unzipped his shorts.
He didn't look away, he didn't joke. He just slid them down.
He was left in his boxer shorts. And then he looked at me again, raising his eyebrows slightly.
"Are you really serious about this?"
"Mhm," I replied calmly.
He smiled to himself, as if it were just another silly thing we were doing for fun.
He pulled down his boxers.
He stood naked in front of me.
His body was clean, proportionate, his muscles tense as if he were slightly embarrassed, but... he didn't try to cover himself. His cock was semi-erect, as if the atmosphere itself was affecting him.
"Okay. You have your test field. Do what you have to do."
He sat back down on the couch. He spread out comfortably, legs wide. As if he wanted to show that he wasn't afraid.
And I... felt it.
Not just excitement. But something deeper. That he trusts me. That he knows what we're doing and isn't running away.
I watched him for a moment longer. I allowed myself to. His thighs were tense, his skin glistening slightly in the warm light. His cock rose slowly with each breath.
I could have touched him right then. But I waited.
Because this was the moment when everything was at stake. And he had just given me control.
"We'll start with the simplest option," I said quietly, reaching for the first gel. I'm supposed to check how it feels in my hand, how it glides over the skin, how it affects reactions.
Justin just nodded and leaned his head back against the couch.
I unscrewed the bottle and smelled a light citrus scent, fresh but not overpowering.
I squeezed a portion of gel onto my hand. Cool, smooth, transparent as glass. It immediately began to spread between my fingers. It was sticky, but without resistance. Slippery, but not watery. Perfect consistency.
Justin looked down.
"Seriously... I'm just supposed to lie there and not move?"
I looked him straight in the eyes.
"All you have to do is tell me how it feels. Leave the rest to me."
He didn't answer. But he didn't back away.
I knelt between his legs. I could feel the warmth of his thighs, the scent of his body, the slight tension in his muscles.
And then I just did it.
Gently, slowly, I reached for his cock.
My slippery thumb touched the base, then I wrapped my hand around it.
He shuddered.
The first moan, quiet, uncontrollable.
I moved up, slippery, without resistance. I felt it pulsing, the skin tightening under my touch, the head slightly shiny, turning pink.
Justin closed his eyes but didn't tilt his head back. He watched me with half-closed eyelids, as if trying to understand what was happening to his body.
"Fuck..." he muttered under his breath. "That feels weirdly good."
I smiled.
Because I was just getting started.
I took my time. This wasn't the moment for speed or effect. It was a test, careful, precise, guided by a hand that knew what it was looking for.
I tightened my grip a little and began to move slowly, in a steady rhythm. The gel worked perfectly, gliding over the skin without the slightest resistance, as if it had been created specifically for this movement.
Justin drew air into his nose. His stomach tensed, his thighs spread slightly apart.
"Breathe," I said calmly. "And talk."
I ran my thumb over the head. I paused there for a fraction of a second longer, feeling it tremble under my touch. The skin was warm, smooth, swollen.
"It's... damn slippery," he mumbled. "And kind of... more sensitive."
I changed my grip. My hand lower, slower movement, then up again, full range. I tested the pressure, the pace, the length of the stroke. I watched every detail: how his fingers dug into the mattress, how his breath caught, how his hips began to respond on their own.
This was more than just jerking off. This was control. Conscious, calm, built on trust.
I sped up just a little. Enough to change his breathing. Enough to feel the pulsing become more pronounced.
"Fuck..." he moaned, no longer ashamed. "This seems to work better than my hand."
I looked down at him. Sweaty, his mouth open, completely devoted to what I was doing.
I didn't answer.
I just continued.
Because I knew his body was already exactly where I wanted it.
I felt it before he did.
That tension under the skin, that slight tremor that starts in the stomach and goes lower. The throbbing in his hand became more pronounced, heavier, as if his whole body was gathering in one place.
I slowed down just for a moment. On purpose.
Justin moaned long and deep, uncontrollably. His back came off the back of the couch, his hands clenched into fists.
I didn't stop.
I didn't change the rhythm.
I was leading him exactly where I wanted him to go.
His cock tensed violently, and then I felt the first strong pulse. The orgasm hit him suddenly, intensely. Streams of cum burst out of him, warm, sticky, spilling across his stomach and chest, smearing over his skin.
He was breathing heavily, intermittently. His eyes were closed, his lips slightly parted, his body still trembling under my hand.
Only then did I let go.
We didn't say anything for a moment. I sat between his legs, watching the result of the test, the way his body had responded, the tension slowly fading from him.
Justin opened his eyes and looked at me with a slight, tired smile.
"Okay..." he muttered. "I have to admit it.
He took a deep breath.
"The gel... and your hand. Ten out of ten.
I smiled slowly, with satisfaction.
Because that was only the first sample.
