She was here, and she wanted him. A grin broke out his face. Aeris giggled and reached for him, eyes sparkling. Vincent took her slim body in his arms, hugging her close. He used his claw to gently tip her head up. He closed his eyes and leaned in. Lips touched and they kissed passionately. Vincent felt something stir in his chest as he recalled fireworks and balloons. He ended the kiss and look down at Aeris. Her eyes were wide with suprise.
"Vincent. . ." She pointed at him.
"What is it?" He looked behind him, at his arms, legs. Vincent panicked. He must have transformed, when the emotions overtook him. That was when it happened. He made to run away, to escape so his love would not see him like this. Aeris forcefully grabbed his hand.
"Come with me." He followed her warily until they reached the clear pool. Aeris brought him to the edge and pointed down at his reflection. He looked down, ready to run if Chaos was emerging. But instead, he looked himself. Except for one thing. White feathered wings had emerged from his back. Aeris smiled as his expression turned to confusion.
"Vincent - now you'll believe. You were never a monster. You're an angel." She paused. "I saw you that day. When you transformed. While I was going to the lifestream, I saw you fight for me. Vincent, you're not a monster. I love you, forever." She hugged him, maneuvering around his newfound wings carefully. Vincent smiled, realizing her words. Gently kissing her forehead, he lifted her up and carried her back to the fire pit.
The fire pit was still glowing with hot embers, and Vincent stopped short of it, remaining in the dim shadows. He looked down at Aeris, who was looking up at him, lust and love apparent in her emerald pools. Holding her with one arm, he used his claw to remove the cloak from Aeris, and draped it over the warm grass. Ever so gently, he lay Aeris down on the cloak. His eyes roamed her body carefully, gently, taking in her pale skin, her full and round breasts, her perfect, muscular legs. He felt himself becoming aroused. He locked eyes with Aeris, silently asking her permission to go on. She nodded, sweat breaking out over her body just from his gaze. She could feel the lust and the love between her and Vincent. Aeris reached forward, sitting up slightly, unbuttoning his black pants. Vincent carefully shimmed out them, leaving him naked except for his dark red boxers. Aeris giggled slightly, locking eyes with Vincent and she reached into his boxers and grabbed him. Vincent gasped, startled by Aeris' forwardness. Gently, Aeris moved her hand up and down, feeling him become erect in her hand. He let out a soft moan, unable to hold it in. He bit his lip, watching Aeris below him. She stopped, and Vincent couldn't help but sigh quietly. He reached down and stepped out of his underwear, now completely naked. Aeris admired his body in the moonlight, his hard abs, muscular arms, and erect manhood. Aeris felt a shudder run through her body. Never had she seen a more attractive man. Vincent leaned forward, gently kissing her stomach, crimson hair tickling her bare skin, moving upwards. Aeris let out a contented sign, feeling her skin tingle where Vincent last kissed. Suddenly, Vincent took her peach nipple into his mouth, sucking gently. Aeris gasped aloud, arching her back slightly. Waves of pleasure coursed through her slim body. Vincent moved his tongue in a circle around her nipple, slowly, feeling a sheen of sweat come out of Aeris' body. While Vincent began to carefully massage Aeris' breast with his human hand, Aeris reached below and began stroking Vincent. Gently, Aeris pushed Vincent upwards. He looked hurt at first, until Aeris' gently lowered her head to his cock. Slowly, she used her tongue to lick up and down the sides, feeling Vincent tense beneath her. Vincent let out a deep rumble. He had never felt this way before. Before he could think about what Aeris' was doing to him, Aeris' took his entirety into her mouth. Vincent let out a moan and she sucked up and down. Gently, he grasped her shoulder, caressing her pale skin. Aeris slowly disengaged, licking her lips, eyes glinting with mischief. Vincent breathlessly looked down at her.
"Aeris..." She lay back on the cloak, grasping Vincent's hand in her own.
"I''m ready, Vincent. Come to me." Vincent kneeled between her opened legs, leaning forward to kiss her passionatly. Their tongues danced together, rubbing and separating. Vincent broke away, catching his breath.
"Aeris, I love you." Gently, he moved inside of her, slowly, feeling Aeris' warmth around him. It was ecstacy, her warm tightness around him. He stopped when he came across her innocence, something he was going to take. Aeris felt Vincent hesitate.
"Go quickly, Vincent." She murmured in his ear, her voice thick with arousal. He nodded, and broke her virginity with one quick thrust. She let out a slight yelp, tensing under Vincent's body. He held her close to him, until he felt her body relax. Looking into her eyes questioningly, she nodded to him. Slowly, he began to thrust in and out, finding a rhythm in time with Aeris'. He could feel her underneath him, tightening and twitching, and he moved quickly. Aeris moaned beneath him, a sheen of sweat over her body. Vincent used his claw to support himself, using his other hand to reach out and massage her breast. Aeris gasped in ecstasy, feeling herself come closer to the edge. Vincent sensed this, and began thrusting faster and deeper. He could feel himself tightening, ready to explode. He let out a moan and he went faster and faster inside of Aeris', listening to her call his name.
"Aeris!" He called out her name as he thrusted deeply, plunging himself inside of her, feeling his orgasm rack his body. Aeris' body tensed around him for a second, then released as she felt the pleasure explode throughout herself. The two bodies relaxed together. They stayed like that until Vincent had the energy to move, rolling over and next to Aeris. He wrapped his arms gently around her, cradling her to him.
"Aeris, I promise I'll love you forever." He caressed her flushed cheek gently.
"Forever, Vincent..." Aeris spoke softly as she snuggled into his arms to settle into a sleep. Vincent smiled, and rested his head on her shoulder as he too fell into a peaceful sleep.
