This is a "what if" one-shot. It's a no looking back, no-regret story. My writing prompt to myself was, what if the uptight Mamoru could let go, act on his desires, and not create a future "if only." This avoids "I've loved you for years, and I wish I told you back then." In this, he does just that. I'm hoping that this will be different and fun. It will seem a bit out of character for him, but that's the point. He lets himself go.

Well, it was official. Mamoru now hated gym class with a fiery passion. He worked to force himself not to give that fact away to his best and only friend, Motoki. He bit the inside of his cheeks, hoping the pain would distract his brain. He knew he needed to work hard to maintain an outward calm.

Motoki stretched his arms above his head to loosen his muscles and asked, "Ready, Mamoru? This will be an easy A. Not that you have to worry about that. You're naturally athletic."

Forcing himself to sound calm, Mamoru said, "I'm ready. At least this unit is only for a week."

"You don't like this?" Motoki asked, confused. "I thought you worked out like this all the time."

"No, don't get me wrong…." He frantically tried to think of how he could fix his mistake. "I just-" Mamoru sighed. "It's inconvenient in the middle of the afternoon."

"You have a point, but at least we don't have PE right after lunch." He elbowed Mamoru laughing. "That would be inconvenient."

"That's an old wives tale, and you know it," he grumbled.

Motoki smiled, "I, however, chose to look at the positive, and right now, there are a lot of benefits to this PE unit. Not that you would notice."

And that was the problem for Mamoru. He definitely noticed the benefits of class this week. While Motoki seemed more interested in looking all around him. It was one woman in particular that drew Mamoru's attention –as always.

He slipped into the pool next to Motoki, glad that it would hide his erection. Usagi was there in a bikini, and he was burning up on the inside with desire. That, and he was trying to figure out how he had missed the fact that her boobs had gotten enormous.

He had never seen fabric work so hard in his life. It seemed to him like the bikini was straining to keep her breasts contained. And just thinking of her bikini snapping and her boobs bursting out drove him crazy. He pictured her tits being exposed, and he almost moaned.

The whole class time, he worked to get a good picture of how her body looked in the swimsuit during PE. Of course, he was careful not to get caught.

He spent a whole week in exquisite agony over Usagi, her flawless curvy body, and gigantic boobs. He didn't even notice any one of the myriads of other women in skimpy bikinis trying to entice him. He did, however, notice all the other guys checking her out. It made him wildly jealous.

He had been shocked all week over how "teenaged boy" his reaction was. He didn't even suspect he could be so lustful until he was confronted by the sexy, nearly naked body of the woman he adored.

It was now Friday after school, and Mamoru was walking home with his bag slung over his shoulder. He had a paper he wanted to perfect that weekend, and he felt the relief of knowing he wouldn't have to be in the pool with her tomorrow. Not that he wouldn't picture her in her suit, but he could be all alone in the shower when he thought of that.

He turned the corner and ran right into the woman he'd been thinking about. Of course, being bigger than her, that meant he knocked her down, sending her books flying.

Mamoru bent down to try to help her sit up and gather her books. The problem was that when she fell, her skirt flipped up a bit, exposing her lace panties in a very private spot. Her thighs were spread, giving him a view of light pink lace. He almost combusted on the spot.

He saw her blush and fix her skirt, flipping it down and covering herself up quickly. He wanted to protest, but he forced himself to refrain.

She fidgeted and said, "That was humiliating. You saw my panties!"

He shrugged and tried to play it cool. "They covered more than those bikini bottoms you wore in class. Don't worry about it." Mamoru watched an odd look bloom on her face.

She shot him a glare, "You're picking on my swimsuit?"

He laughed. "Ha! No. I'm complementing it."

Collecting her scattered books, he noticed she stood, and after he had them all, he slowly stood, too, looking at her long legs as he did. He added, "Here, this should be everything."

She grabbed her books from him and put them back in her school bag. Usagi then asked, "Did you just check out my legs?"

He answered, "Yes."

Blinking up at him, she asked, "You noticed my swimsuit?"

"No," he replied quickly. When she looked at him skeptically, he answered boldly and honestly. "I noticed your body."

"M-my body?"

He caressed her arm gently. "I did, but don't worry. I'll let you be, and I'll head home."

Mamoru started walking away, but her next word made him freeze in his tracks. "What do you like most about my body?"

He spun to face her and replied with his hormones. He couldn't help it after seeing the pink lace crotch of her panties. He looked her up and down like a predator eyeing a meal and said, "It's not any one thing I enjoy. You have a killer body, and I appreciate the whole thing." He then leaned in her space and whispered, "And I wasn't quite honest before. I liked that suit and how hard it looked like it was working to keep your boobs contained. I was a bit disappointed when it didn't give in and snap from the sheer strain."

Usagi swallowed hard. He liked watching the effect his words had on her body. It was flush, and she was breathing harder too.

"You want to see my bare boobs?" she asked him.

He wanted to snap at her for teasing him. It was something he wanted so badly, and there she was, dangling the possibility like some taunting carrot.

Mamoru realized she read his reaction to her question perfectly when she laughed at him. She then said, "It's a real offer Mamoru. Do you want to take me to your place?"

"Yes," was all he said, but he could tell she knew he was excited by the offer. He grabbed her hand, lacing their fingers together, and hurriedly pulled him with her toward his apartment. For the first time in his life, he was glad he lived independently.

Once they got to the elevator, he was sweating. He couldn't believe he was bringing Usagi to his apartment to look at her bare boobs. He asked himself if he was really going to go through with this. His straining erection was definitely voting yes, along with his hormones. Again it floored him what a ball of hormones he really was when he got around her.

He briefly wondered if he should explain that he was in love with her too, but pushed that away. He was getting more out of her than he ever expected, and he decided not to burden her with his feelings. He could act like it was all physical. It's not like that wasn't a big part of what was happening today.

He felt her take his arm and lean against him. It was soft, and when he looked down at her, he noticed her breasts were pressed to his arm. He couldn't help himself. He groaned.

By the look on her face, she knew exactly what she was doing to him. Usagi stated, "You're a boob guy."

He shrugged a bit, feeling the brush of her breasts against his arm and loving it. "Honestly, I didn't know I was until I saw you in that tight bikini top."

She rolled her eyes dramatically at him and gave him a sour look. "Right. Like I believe that. You don't have to lie about it."

He ran his free hand through his hair as the elevator dinged, and they stepped out. No one was in the hall, so he felt free to keep talking. "It's like you take up all the air in the room, Usagi. I don't notice other girls. Only you. For a long time now."

"I'm not around all the time," she challenged.

He nodded, "But then I'm thinking of schoolwork and what I need to do for cram school."

She stopped and looked at him, not releasing his arm. "I'm really the only girl you notice? What about Sakura?"

"What about her?" he asked, obviously confused.

"She perfectly described your apartment and your bedroom in excruciating detail," she said with a meaningful stare.

He pulled her with him, unconcerned. He opened the door to the apartment and pulled her in with him. "How did she do?" He asked.

He watched as she looked around, wandering from the living area with the huge TV to the small kitchenette. She looked back at him over her shoulder and, smiling, said, "The place she imagined was much nicer."

He laughed and shook his head in amusement. "I live alone. I don't need that much."

"Okay," Usagi said. "So Sakura is full of bullshit." She then turned to face him fully. "Was that still a line?"

He shook his head. "No. I know I'm like a vault with my feelings. Matoki tells me that a lot. But… Something in me can't hide the truth from you. I'm sure it doesn't help that I've been seeing you in that bikini all week."

She smiled at him playfully and pulled off her shirt and then her bra. "Do you like them?"

He found himself frozen in place. His mouth was watering, surprising him, and his palms itched. Still, he didn't move. She said he could look at them, and he clamped down hard on his raging desire and forced himself to respect her parameters. After all, he didn't have to imagine what her breasts looked like anymore.

"Y-yeah, I like them –a lot. I can't believe I get to see your tits." He refrained from stroking his cock no matter how much he wanted to right now. He felt like he needed some kind of relief.

As she walked toward him, he swallowed hard as he watched her boobs bounce with each step. She smirked and asked, "Do you want to touch them?"

"Yes. So much!" He admitted it easily. "May I?"

"Yes."

He didn't even stop to consider that she meant he could touch her with his hands. His mouth was suckling her tit as fast as he could get his lips on her while his hand was gripping her breast, pressing it up. His other hand went to her other nipple, and he pinched her as he also grabbed the globe of her boob. It took a while, but he eventually registered that she was moaning.

Usagi's hand went to the back of his head, and she encouraged him to use his mouth more on her. She moaned again, and she said, "That feels so good. You really like my boobs, don't you?"

He looked up at her, still sucking on her nipple, and spoke with his mouth full, "I fantasized about you like this."

He was so distracted licking and sucking in her breasts that it took him six minutes to realize she was doing something. He pulled his head back, his hands still on her breasts, as he looked and noticed her hand was under her skirt, and she was fingering herself.

With one hand still grabbing her tit, he used the other to lift her skirt, and he watched as she fingered herself. Her panties were pulled to the side, exposing her bare pussy while she touched her clit and slid her fingers through her obviously slick folds. He hadn't realized just how hard he could get until that moment.

"I really like looking at your wet pussy, too, Usako." It didn't even dawn on him he used a pet name for her. He was too wrapped up in watching her working to get herself off. "Does that feel good, touching yourself?"

She moved, and it broke his hold on her. He was more curious than disappointed. Usagi pressed her back to him and brought one hand to her breast. He squeezed and began playing with her again. As he did, he was startled when she brought the other hand to take over what hers had been doing with her pussy.

He pulled her panties to the side and fingered her clit, feeling her soak his fingers. He breathed hot and heavy in her ear as his erection was hard and nestled between her ass cheeks through her skirt. He huskily whispered, "I like you wet like this even better. Although seeing you wet in the pool was very sexy."

"I'm surprised how much you're willing to do with me."

"What do you mean?"

"I didn't know you wanted to do more than look at me. I mean…" she paused and moaned when he flicked her clit. "I didn't expect this."

He chuckled darkly and pressed his cock against her ass. "Can't you feel how hard I am? How can you not realize I'll do anything with you that you'd let me? I'm your servant."

She looked up at him with hooded eyes. And he realized exactly what "bedroom eyes" looked like. Usagi asked, "And if I wanted to do more with you?"

"I need to know now if that's a hypothetical or an offer!"

"An offer."

She squealed when he picked her up bridal style and carried her to his bedroom. Once she got there, she let out a little laugh. "Sakura was off about this room too."

He laid her on the bed, pulled off her panties, and then her skirt. "I'm not even sure who she is. Do I have science with her?"

"No PE."

He laughed loudly at that. "You're the only woman in PE I ever notice. I bet I couldn't pick her out of a lineup."

He then spread her legs and then ran his finger through her folds, brought it to his mouth, and then sucked it clean. "You're all I see."

She chuckled, "My legs are spread wide for you, and we're in your apartment —alone. Of course, I'm all you see."

"True. But I'm telling the truth. You're the only one I want to have here like this." He noticed a look of hesitation on her face. So he pressed on. "Usagi. Do I really seem like I've done this before?"

She cocked her head. "Actually? Yeah. You're so good at everything you've done with my body."

He shook his head. "No. No, never." He needed her to believe him. "I have a very vivid and active imagination. And it's embarrassing to admit that I've imagined touching you for…." He blushed. "A long time. You've always been just out of my reach, though. That was until today, and I couldn't let myself hesitate. I can't let myself fail to please you. Deep inside, I need this not to be a one-time thing. It's not prior experience. It's the desperation I have for you."

He took her ankles in each hand and lifted her legs, bringing her ankles near her ass and spreading her pussy wide open. He locked eyes with her wet pussy and licked his lips. "Usako," this time, he said it on purpose. "I might be a pervert enjoying looking at your cunt so much, but it's because it's your body that I want so much."

He took his middle finger and slid it inside of her and watched as she arched her body and moaned. "How many times have you done this?"

"Never before," she moaned as he curled his finger.

He gave her a smart-ass look. "Then how in the hell would you know if I was any good at this?"

She shot him an unimpressed look. "I can feel how good this all feels. I'm not stupid, just inexperienced."

"Same," he said as he added another finger inside of her. He watched her chest heave with pleasure and said, "It's not like your body is hard to read. Like in everything, you're very expressive. I really liked that about you before, but now I find it so hot."

He loved the grunts and moans he got out of her as he fingered her. She was almost wild, squirming on his bed as she rode his fingers. "Please believe me," he begged. "You're the only one I've ever wanted like this and the only woman I've ever even kissed."

She raised an eyebrow as she impaled herself on him. "You got here from never kissing before?"

"And you?" He challenged her.

She shuddered from pleasure and said, "You're the man of all my fantasies. Once I got the smallest hint you wanted me, I was desperate to throw myself at you."

He scissored his fingers in her and nipped her tit. "You're the only one I think of as I jerk off every time. Why would I pass up any chance to see or touch your body?"

"Truly?"

"Yes," he promised. "Would you be my girlfriend? I'll prove my desire and affection for you, Usako."

"Yes, Mamo-chan. I'll be yours."

He flicked her clit, and she orgasmed. She looked up at him with a sated look on her face with her chest heaving, panting for breath.

Mamoru moved and pulled off his shirt and then his pants and boxers. "Usako, umm… Could you suck my cock?"

"One of your fantasies?" she asked.

He nodded. "Absolutely." He smiled as she got on her knees and stroked his cock.

She touched the head of his penis as she asked, "Will you be able to have sex tonight if you cum in my mouth?"

"Usako, I wasn't kidding about my lack of sex life. I don't have condoms."

She blinked up at him after kissing the head of his penis. "I'm on birth control. And I believe you about not being with a woman at all before. Do you believe in a virgin too?"

"Yes!"

"Then we don't need a condom." She hesitated and added. "That is if you want to have sex."

He flipped her to her back and covered her body with his. "I want this so badly." He didn't hesitate then. He penetrated her with his hard cock, breaking her maidenhead. "You're mine."

"Yours," she agreed readily as he began setting a slow, steady pace.

He grabbed her boobs as he felt himself having sex with the most amazing woman in the world. He couldn't believe he was finally there inside of her like he'd only dreamed. It was so much better than he could have ever imagined. As his desperation amped up, so did his pace.

He was taking her hard and grunted out, "Can I cum inside of you?"

"Yes, please. I want that."

He nipped at her neck and thrust deep into her making her scream out in pleasure. "Good. I don't want to have to pull out. This feels so damn good. You feel amazing! Usako, I've wanted you for so fucking long." He quickly buried his head in her hair, hiding the tears in his eyes. He was overwhelmed with the pleasure of having sex with the one woman he ever loved.

With them both being virgins, it didn't take long. They both orgasmed, screaming in pleasure. He collapsed onto her, his limp dick still inside of her. Not wanting to pull out to prolong his contact with her.

Once his breathing was more under control, he shifted and held her in his arms by spooning her. "I've never been so happy," he whispered. "I didn't think you'd ever be interested in me."

She nestled deeper into his arms. "Same. We talk, but you always seem like you are keeping some distance between us."

"I was. I thought my feelings for you would be obvious if I didn't. I'm in love with you, Usako." He was honest because it would have felt funny hiding his feelings for her after what they just shared. "You're the only woman I really talk to."

She laced the fingers together of their right hands. "I know, and it made me feel silly. It got me hoping you'd fall in love with me too."

He kissed the back of her neck. "Already done. You've owned my heart for a year and a half."

She raised his hand with hers and kissed the back of it. "You own mine too. And now you have my virginity."

"And you have mine."

She looked back at him, smiling. "I'm really grateful Minako talked me into that bathing suit."

He chuckled and kissed her shoulder. "Damn, am I too."

They both fell asleep happy and content in each other's arms.

Their love, they each confessed that day, lasted through the decades.
