The tall grass whispered against her bare thighs as Lena pushed deeper into the secluded clearing. She was twenty-four, a seasoned trainer who knew better than to wander off the path half-naked, but the heat between her legs had been building since dawn. Her shorts lay discarded somewhere behind her, and the cool evening air kissed her slick folds every time she moved.
A low growl rumbled from the shadows. Her Arcanine stepped out, massive and golden-furred, eyes glowing with the same hunger she felt. They had been partners for years, but tonight the bond had snapped into something rawer.
Lena dropped to her knees in the soft dirt. “Come here,” she said, voice already hoarse. The big canine padded forward, his sheath already swelling, the tip of his cock peeking out, red and glistening. She wrapped both hands around it without hesitation, stroking the hot, veined length as it slid free. It was thick, ridged, and already leaking. She leaned in and dragged her tongue from base to tip, tasting the sharp, musky pre that beaded there.
Arcanine’s hips jerked forward. Lena opened her mouth and took the head, sucking hard, letting her spit run down the shaft while her fingers worked the knot already starting to form. The Pokémon rumbled, a deep chesty sound that vibrated straight through her. She moaned around him, the vibration making his cock twitch against her tongue.
She pulled off only long enough to strip her tank top away. Her breasts bounced free, nipples tight. She pressed them around his cock, sliding the slick length between them while she licked at the tip each time it pushed up toward her mouth. Arcanine’s front paws planted on either side of her, caging her in.
“Fuck, you’re so hot,” she breathed, voice filthy. “Gonna knot my tits if I let you.”
She didn’t let him. Instead she turned, bracing on hands and knees, ass raised. Her pussy was dripping, lips puffy and parted. Arcanine mounted without further invitation, powerful forelegs locking around her waist. The first thrust missed, sliding hot and wet along her ass crack. The second found her entrance and drove straight in.
Lena cried out, the stretch immediate and brutal. He was bigger than any human she’d taken, the ridges dragging against her walls as he buried himself to the knot in one long push. She clawed at the grass, pushing back to meet him. “Harder,” she gasped. “Don’t hold back.”
He didn’t. The thrusts came fast and deep, each one slamming the growing knot against her entrance. Her juices ran down her thighs, mixing with the thin pre leaking from him. Every slap of fur against her ass echoed through the clearing. She reached between her legs, rubbing her clit in tight circles while he fucked her.
The knot swelled, catching on her rim with every withdrawal. On the next thrust it popped inside, locking them together. Lena’s orgasm hit like a thunderbolt. Her cunt clamped down, pulsing around the thick intrusion as she came hard, squirting around the knot. Arcanine growled, hips jerking in short, grinding motions as he emptied into her, hot pulses flooding her womb.
They stayed locked, panting. Lena’s arms shook. She could feel every throb of his cock inside her, the knot keeping every drop trapped.

When it finally shrank enough to slip free, a thick rush of mixed cum spilled out of her, splattering the grass.
She rolled onto her back, legs spread, chest heaving. Arcanine licked her clean with long, rough strokes of his tongue, lapping at her oversensitive clit until she came again, softer this time, thighs trembling around his muzzle.
Later, when the moon was high, she straddled him instead, sinking down onto his cock once more while he lay on his side. She rode the knot slowly, rolling her hips, letting it stretch her over and over. Her hands braced on his broad chest, nails digging into thick fur. Every time she dropped down she moaned his name like a prayer.
By the time the sky began to pale, she was sore, marked, and satisfied. She lay against his warm flank, his seed still leaking from her, and smiled into the dawn.
The tall grass hid them both.
