Gwen opened the door to Kevin's bedroom. "Hey, Kevin, is there anything I can-"

"Whoa, Gwen, wait!" Kevin instinctively grabbed his towel and held it close to his body. It took a few seconds for Gwen to realize that he was wearing nothing except for a pair of briefs.

"Oh, sorry." She blushed, although she wasn't sure if it was because she wasn't expecting to see him in such a state or because she liked what she saw. "I didn't realize you weren't done. Um..." She cleared her throat in an attempt to stave off the awkwardness of the current situation. "I'm hungry. I didn't wanna go looking through your fridge because I thought it would've been rude, so I came in here to ask, but you're-"

"Kinda underdressed."

"Yeah." Shutting the door behind her, Gwen approached Kevin. "But you know you don't have to hide from me, right? Did you forget the time you spent months fighting crime in your underwear?"

That was a stressful time for them, but she knew neither of them could forget it, for better or worse. They had just started dating and a failed attempt at hacking the Omnitrix left Kevin temporarily stuck as a mishmash of different materials. Gwen found it amusing that he decided to wear a simple pair of underwear as his default attire. She never let it get too obvious, but she had a difficult time taking her eyes off him.

She took his towel in her hands, rubbing it through his wet black hair to soak up all the water, then kissed him on the cheek for good measure. "There." After hanging the towel on a nearby rack, she walked back to him and surveyed him from top to bottom. It had been a while since she saw that much of him. His skin was flawless and his body was perfectly toned. Whatever he had been doing to keep himself in shape was certainly working. As a bonus, the smell of his body wash and shampoo lingered around him. There was something about seeing him out of the shower that always made her want to drop whatever she was doing just to breathe him in.

Taking notice of her staring at him, he laughed nervously. "Somethin' the matter?"

She shook her head, grinning. "You're beautiful. I feel like I don't tell you that enough."

The boy smirked, putting his arms around her waist. "Well, now's your chance to get everythin' outta your system."

"Better yet, let me show you." Smiling deviously, she nudged him onto his bed so he was sitting up, then straddled him. While her hands were tangled in his black locks, her lips crashed down on his. With Gwen distracted, Kevin's hands snuck under her shirt, his fingers trailing up the smooth and soft skin of her back to toy with the strap of her bra. Having caught him red-handed, she broke apart from the kiss and playfully wagged her finger at him. "You, Kevin Levin, need to learn to be patient."

Kevin slipped his hands out of her shirt, rubbing the back of his neck and avoiding eye contact. "Yeah, guess I got too excited there. Sorry."

Gwen tapped a finger on her chin. "But you know, you do deserve to blow off some steam. You've been working extra hours at the body shop, and I'm really proud of you for all the good you've been doing lately. So, you know what? Here's your reward."

She stood up, and before he even had a chance to blink, Kevin's vision was obstructed by a blindfold made of mana.

"Baby?" She didn't reply. His heart thumped in his chest in anticipation as he asked himself one question: What was she planning?

Much to his relief, he didn't have to wait long for an answer. His blindfold disappeared into thin air, and what he saw made his face light up as if he were a child at a toy store. Gwen stood a few feet away from him; her shirt, vest and pants scattered on the floor around her. The only thing she had on was his T-shirt.

Her fiery mane now flowed freely and Kevin's shirt clung to her body loosely, exposing most of her shoulders and stopping right below her knees. It appeared more like a mini dress on her than a shirt. A very thin mini dress, at that.

Kevin was positive there weren't words in the English language that could describe the excitement that coursed through his veins. He'd dreamed for a long time about seeing her in one of his shirts, and she didn't look as good as he thought she would. She looked much better.

"Now, where were we?" Beaming, she jumped on him and placed her hands on his chest, pushing him so he lay on the bed on his back. He breathed heavily as she peppered quick kisses all over his face. He felt her moist lips journey past his neck all the way down to his stomach then back to his face, leaving traces on every inch of skin his body had to offer. She cupped his face and affectionately grazed his nose with her own.

Kevin's tongue emerged from his mouth, gently brushing against Gwen's lips. As it wiggled its way into her mouth, their tongues touched, twisting and interlacing to wrestle for dominance. He tasted like toothpaste, but she didn't care.

With their tongues locked in a passionate slow dance, Kevin's hands moved down Gwen's sides, making their way down to the curves of her waist, squeezing her hips. She responded by murmuring softly against his lips, sending a shiver down his spine.

Desperate for air, she very reluctantly retracted her tongue and pulled away from the kiss. Her warm breath tickled his face as she huffed.

"I learned a lesson today.", said Kevin. Gwen moved a hand to his chest, cocking her eyebrow. "Is that so?"

He chuckled. "Yeah. I should leave my door unlocked more often." The redhead glanced at his body, a glint of mischief in her eyes. "I wouldn't be opposed."

He looped his arms around her shoulders, holding some of the fabric of his shirt between his fingers. "My shirt looks good on you." Gwen smiled at his compliment, batting her eyelids. "Good enough to let me keep it?"

"Of course." He kissed her forehead. "Gotta say, I didn't know it was that comfy."

"It is, but there's also something else. You know how I can sense people by touching something that belongs to them?", she asked.

Kevin nodded. "You want to keep the shirt so you'll always feel like I'm with you."

"Pretty much, yeah."

"Y'know, I'm with you right now. What say we just lie here and make out 'til I have to send you home?" He nibbled on her lower lip.

"Tempting." She giggled, gently pushing him away. "But I'm hungry."

To Kevin's disappointment, Gwen got off the bed, extending her hand for him to grab. He took her hand, pouting. In an attempt to comfort him, she placed her hand on his chest. "Think about it like this. The quicker we eat, the quicker we can come back here and do stuff."

"When you put it that way..." With little effort, he lifted her off her feet and held her in his arms bridal style, rushing out of the room.

This seemed better in my head. I hope it was acceptable.
