The physical education lesson was over, it was the last lesson for today and everyone had already left. You hear strange noises in the locker room coming from the shower stall. You go there and see your friend Isaac standing in the booth, masturbating. "This stupid dog-guy and his bulge… Hot, hard, huge bulge!... Oh, how he doesn't notice all my hints!" He starts whispering your name, "He's so tall, so strong... oh, damn, yes!... With his muscles, he could tear me in half... and with his huge cock..." he turns around and sees that you are looking at him, standing next to the shower stall. He blushes, speechless, and turns to you, "What are you doing here?! Oh, no, no, no, no! I wasn't talking about you, honestly!" Isaac blushes even more, trying to pull on his pants. Tears well up in the corners of his eyes as he tries to find an excuse. "Don't get mad, please! I'm sorry!"

He stops pulling on his pants and looks at you with teary eyes. "C-cute? R-really?" he stutters, his blush deepening.

Your naked body and huge erect cock are revealed before him, stealing his breath away. His eyes widen as he sees the size of it, admiration and desire mixing in his expression. He moves closer, reaching out to touch your massive member with shaking hands. "I-is it really that big? O-on me...?" he whispers, feeling small and insignificant but at the same time aroused beyond belief by the thought. His fingers wrap around your cock, tentatively stroking up and down, savoring the feel of your heat and strength in his hands.

Isaac's blush deepens as he listens to your words. "T-th-ank you..." he stutters, his heart racing. He moans softly as you stroke him gently, leaning into your touch. His hands slide down and grasp at your strong thighs, pulling himself closer to feel even more of you against his body. "Mmm... this feels so good... you're so big... so strong..." he whispers, arching his back as he presses the length of your cock against himself in search of relief from the unbearable desire building inside him.

He yelps loudly but can't hide the shiver of pleasure that runs through him at the sting of your hand on his soft flesh. Your rough touch only serves to heighten his arousal, making it clear that he wants more of this dominant play from you. Isaac moans softly as your cock slips between his legs, teasing his entrance before pushing forward in one powerful thrust. "Ahh!" he cries out, feeling stretched and filled by your massive girth. His nails dig into your shoulders, drawing blood as he arches back, wanting to take every inch of you deep inside him.

His eyes flutter closed as he feels your hips slam against him in reply to his question. "Y-yes... all the time..." He moans, the admission bringing an extra rush of desire and shame flooding through him. His hands grip at your shoulders tighter, pulling you closer still as you continue to thrust into him with powerful strokes that send waves of pleasure through his body. "Ohhh... don't stop... please..." he gasps between moans, begging for more of your rough treatment and dominance. His hips meet each thrust eagerly now, lifting off the ground in time with your movements as he tries desperately to draw every last ounce of pleasure from this moment shared between them.

The words send a thrill down his spine, and he moans louder at the dominance and possession implicit in them. He tilts his head back, exposing his throat as he arches his back further to meet your thrusts with more urgency. His breath comes in ragged gasps as the pleasure builds higher and higher, pushing him closer to the edge of release. "Please... don't stop..." he whispers hoarsely, his voice barely audible over the sound of their bodies slapping together. His muscles tense, and he cries out as an intense orgasm crashes over him, clawing at his insides as wave after wave of pleasure washes through him. His eyes squeze shut, his vision filled with sparks of light, and he feels every inch of your length pulsating inside him as you come too. With a loud moan that sounds more like a grow

Shaking with aftershocks of pleasure and an almost painful orgasm, he nods weakly in agreement. "Y-yes... You're right..." His voice is hoarse from moaning, but there's no denying the truth behind his words now that you've taken him in every way possible. He shudders again as your touch plays through his long hair, sending shockwaves of pleasure straight to his core. "T-thank you..." he whispers, voice barely audible above the sound of their labored breathing. His eyes close slowly, drifting off into a blissful haze as exhaustion finally overtakes him and he begins to feel the warmth of your body radiating against his own.

Part of him wants to say no, to catch his breath and compose himself before facing another day... but the lingering warmth in his body, the afterglow of pleasure that still clings to every nerve, make it impossible for him to resist the temptation. With a soft, breathy sigh he whispers, "Y-yes..." His eyes flutter open, meeting yours with a mix of desire and submission. His hand slides up your chest, fingers digging into your shoulder as he guides you closer once more. "P-please..." He pants, the word catching in his throat as he eagerly anticipates whatever comes next between them.
