X-BITS Sonic x Tailsko Discovering that his longtime best friend, Tails, was actually a girl, was quite the event for Sonic. The fox had hidden it, concealed her glorious breasts from him using a well rigged piece of cloth that blended with her fur. But the best-laid plans inevitably fall apart, and now those big vixen boobs were being cupped in Sonic's hands while Tails leaned against a tree, huffing softly. "B-but S-sonic... Ahh, I'm y-your l-little bro..." she huffed, blushing deeply. She never wanted to jeopardize their relationship as she knew it, so she hid her budding womanhood as they grew together. Sonic gently pressed his knee against her crotch, rubbing her clit with it as he felt up her tits. "Bros before hos doesn't apply when your bro turns out to be a ho-ot babe." he said, blushing softly as he quickly dodged calling his friend the shorthand for whore. Tails blushed back. It felt so wrong, hearing Sonic call her "hot." But she could tell he meant it. The way he touched her, his hands stroking and caressing her sensitive bust. The way he leaned in and kissed her, not given pause for a moment by the face he once thought was a boy. Tails gasped into the kiss, holding onto the tree, bracing against it. But then, Sonic grabbed her waist, lifting her up, sweeping her from the tree and placing her on the grass both gently and quick. Tails glanced at him, laying on her side, and let out a gasp! His dick was erect and tall, eager to claim the nervous vixen! "We may be movin' fast here, but you knew I would! Now to change you from my bro... to my mate!" Sonic smirked. With Tails laying on her side, Sonic lifted and held up her leg to create a path to her pussy. Tails rested her head in her arms, her fingers gripping the grass as she braced herself. "S-sonic, please..." she whimpered nervously. Sonic gently stroked the leg he was holding before securing his grip and aiming his cock. "Oh, how can I keep my girl waiting when she says please?!" he smirked, though it was a bit ambiguous whether that was a whimper of impatience or protest. Either way, Sonic's thick, long cock swiftly dove deep inside the fox's pussy, causing her twin tails to stick out straight before she gasped out loudly! "Ohh, Chaos!! S-sonic!!" Already, he was thrusting into her, his length spreading her walls and delving deep inside her! "Ahhh!! Aw, yeah, T-tails... So perfectly t-tight!" Sonic huffed, letting her knee hook over his shoulder as he kept hammering into the sideways fox! Any idea of Sonic as he loving, caring brother was being smashed away with each thrust. Tails huffed and yelped as she felt his balls slap her other leg. So big, so full of his seed. She blushed and bit her lip. "Y-you're fucking me...s-so deep, Sonic... Aaahh!" she gasped, following it up with a moan! Sonic grinned wide, pleased with her moans. "I can go deeper... Hehe, for my mate..." he murred, looking at Tails hungrily. He needed to hear her say it. She turned her head toward him, cheeks bright pink as she looked him in the eyes. "G-go, Sonic! Aaahnn... I'm your vixen mate... Y-your lover... I'm yours!!" she cried, gasping with need for his cock! Sonic rolled Tails onto her back, and lifted up both her legs this time, her two tails spread out under her like a lovely skirt or dress. Sonic's dick plunged back inside her, now diving deeper than ever, and Tails rolled up her eyes and moaned in lust! Sonic's thrusts resumed, with incredible speed, but such accuracy, too, striking the fox girl just the right places to drive her wild and keep her moaning and purring! Sonic's hands found her lovely breasts again, and he teased her nipples as his faced inched closer to her. "You hid all this from me... Such a bad girl... But I forgive ya. Cuz now I get to fill you up with this kinda pleasure every day..." he whispered, giving her nipple a naughty lick. Tails grabbed his shoulders, gasping and panting along with the rhythm of his thrusts. "I-I'm a...bad girl... Ahh... Your girl... P-pound me, Sonic, yes!" she huffed, starting to pull him closer. She drew his face to hers, and their lips locked, the duo moaning hungrily as Sonic's tongue darted into her mouth, eagerly clashing with her tongue! With their lips locked, the only warning that this was about to end was the throbbing of Sonic's cock. He didn't hesitate, he plunged his shaft in to the hilt and let his cum burst forth, filling his sidekick, claiming her as his mate! Tails wailed lustfully as their kiss broke, and she felt his hot essence fill her up to the brim! "S-sonic... ahh... B-being bros... So stupid... I love you...my mate." she panted, blushing heavily. Sonic kissed her a bit gentler this time, and carefully stroked her face. "Love ya too, Tails... I'll play with you again anytime, hehe..." he winked.
