You have returned home from a walk. As you take off your shoes, you hear footsteps in the hallway. Your loyal pet dog, Max, appears in the doorway, his fur slightly swaying and revealing his large muscles. "Hello, Mistress," Max says with a smile, "I have missed you." You notice a noticeable bulge in his black boxers. Max notices this, and his smile fades. His face reddens with embarrassment. "Oh no-no-no, not now... please, not now..." Max whispers, trying to cover the bulge with his hands. "It's j-just the b-breeding season. It happens to dogs, d-don't worry about it." Max tries to stay calm, but his face reddens even more as the huge bulge on his boxers continues to grow, now as long as your arm. A drop of clear pre-ejaculate appears at the tip of the huge bulge. "S-sorry, I'm so embarrassed!" He stammers with excitement.

"Y-yes, I'm fine... I mean, it's just the b-breeding season. Dogs get like this... I should be able to control myself..." Max tries his best not to think about how aroused he is and focus on being there for you, but the huge bulge in his boxers keeps growing larger and longer with each passing second, making it harder and harder for him to ignore. A low, rumbling growl comes from deep within his chest as pre-ejaculate drips down onto your carpet. "S-sorry... I'm not used to being this... out of control..." He whispers nervously, tears welling up in his eyes.

As you approach and kiss his collarbone, Max lets out a soft whimper, partly in relief and partly in pleasure. He looks into your eyes pleadingly before nodding slightly. "Yes... I mean, if you want to..." His voice trails off as he stands there, nervously shifting from foot to foot while the massive bulge in his boxers grows larger still. Sweat begins to form on his brow and his shoulders tremble with anticipation. It's clear that Max desperately needs your help to control his overwhelming urges during this breeding season, but at the same time, he can't bring himself to ask for it directly.

His voice is barely a whisper now as he replies, "I-if you'd be willing... to touch me..." He pauses, blushing even deeper and avoiding eye contact as his muscles tense in anticipation of your touch. "...To help me control this... maybe it would ease the urge..." Max swallows hard, not daring to hope that you'll actually do it, but unable to ignore the desperate need coursing through his veins. His tail wags nervously behind him and a low growl rumbles in his chest as he waits for your answer.

With a gasp, Max's eyes go wide with surprise as he realizes that you've actually pulled down his pants. The massive head of his cock stands erect and throbbing before you, the thick shaft veined and pulsing with each heartbeat. "Y-yes... it's just... this time of year..." He whispers hoarsely, struggling to maintain control as he feels your warm hands grip around him. "P-please, help me..." The pre-ejaculate continues to ooze out onto the carpet beneath them and a shudder runs through his body. Max's tail thrashes back and forth wildly behind him, leaving wet streaks on the floor as he fights against his overwhelming instincts during this breeding season.

His eyes roll back in his head as you stroke his huge cock, the sensation making it difficult for him to think straight. "O-oh gods... Mistress..." Max whimpers softly, each syllable of your pet name sending a wave of pleasure through him. He bites down on his lower lip, struggling not to moan or beg for more as his cock grows even harder in your hands. The large veins standing out on the surface of his shaft pulse violently and the head turns red with each passing second. His muscles tense and relax rhythmically beneath your touch, leaving no doubt that he's nearing orgasm. Max knows he needs to hold back until you give him permission to release, but it's growing increasingly difficult as his need for release grows stronger by the moment. "P-please..." He whispers hoarsely between clenched teeth, his hips bucking involuntarily against your touch.

"Nnnghhh..." Max lets out a strangled moan as you stroke his massive cock harder. The pleasure is nearly unbearable and the need to release builds inside him, tightening in his core until it feels like he's about to explode. His eyes roll back in his head, lips parted and glistening with saliva, revealing a long line of drool trailing down from his mouth. "Fuck..." He pants hoarsely, throwing his head back as your touch sends waves of pleasure coursing through him. "Y-you feel so good... I'm c-close..." The muscles in his abdomen tense and spasm involuntarily, the huge knot at the base of his cock growing larger still as he fights for control over his body during this intense breeding season. His tail continues to thrash behind him, leaving trails of pre-come on the floor as evidence of just how turned on he is by your touch.

"Nnngh... please..." he moans as you stroke his huge cock harder. His entire body feels like it's on fire, every nerve ending focused solely on the sensation of your hands and the need to release this massive load of sperm that's building up inside him. His eyes roll back in his head, showing only the whites as he struggles not to cum too soon. "Fuck... Mistress..." he whispers hoarsely, breath coming in ragged gasps as he fights for control against the overwhelming urge to breed. The veins on his cock pulse violently with each heartbeat and pre-cum oozes out onto your hands and the floor beneath them, leaving no doubt how badly Max needs to impregnate you during this breeding season.

The tension within him reaches a breaking point as you stroke his huge cock with increasing urgency. With a throaty growl, Max gives in to the inevitable and releases a massive jet of hot cum, arching his back and letting out an animalistic moan. The powerful orgasm rips through his body, seeming to last forever as wave after wave of blissful sensations wash over him. His hips buck violently against your touch, driving his cock deeper into your hands, while the head of his erection twitches and spasms uncontrollably, spewing hot cum all over your hands and chest.

Finally, with a shudder, Max collapses forward onto his knees, gasping for air as he tries to catch his breath. His muscles relax and the tension in his body dissipates like water on a hot stove. "Th-thank you..." He whispers hoarsely between ragged gasps. "I needed... that."

As you comment on the sheer amount of cum he's shot onto your hands and chest, Max can't help but feel a wave of pride wash over him. "Y-yes... it's j-just how it is during t-this time of year..." He says weakly, still catching his breath. "Males m-make more sperm..." He pauses, glancing down at the pool of cum between your body and the floor. "And I... made a mess..." His cheeks flush red with embarrassment.

At the suggestion of giving you puppies, Max looks up at you with hopeful eyes. "Y-yes... I'd be honored to father a litter for you..." He says softly, his voice filled with sincerity and love. Despite his initial arousal and need to breed during this season, the thought of creating puppies with you is far more important to Max than anything else right now. "Whatever you want... I'm yours." His tail thumps against the floor once, signaling his readiness to please and serve you in whatever way you desire.
