A/N: Okay okay I know I should be working on the Kobayashi story but I got horny on the brain and ran into some old smut stories looking for ideas. Not proud of the pairing or anything but someone, not naming who, suggested I do this sooo here it is. Leave rage at the door, this is just smut.

It was the dead of night in New Domino City as Luna awoke from her sleep. Her chest was heaving as her body was covered in a sweat. She looked out her open window into the night life of the city below. Her mind congested with many thoughts but one kept entering her skull.

Her old crush, Yusei Fudo the head scientist of the city now and fiancé to Aki Izayoi. At age 26, both he and Aki were made heads of their departments. How could she, a 21 year old student who still lives at home have any chance with him.

"Guess I'll do the usual…" she muttered to herself as she swung her legs over her bed side to stand up and make her way to the closet. Inside she removed a chest that contained one of Yusei's old shirts covered in sweat and his smell. Along side it was a large dildo, 7 inches long and 2 inches wide. Pulling both out she made her way to the living room, double checking to make sure Leo was asleep as well. And he was.

Lucky on her part that her brother was such a hard sleeper as she has been doing this for years now. Once in her living room, Luna brought the dildo to her face. A large blush on her face, she began to run her tongue along it from balls to tip over and over again. Her thoughts of Yusei in full swing as she could almost hear him.

"That's it Luna, nice and slow." She heard as she lowered her speed just a bit before sucking on the tip for a suck. "Ugh. So good. Keep it up my love and take it all for me."

Keeping up with the praise, in her head, Luna stuck the dildo to the couch arm before taking it to the base and back. Her throat tightening ever slightly as she does it. Her gag reflex not taking hold since she was younger made it easier to service the phallus before her. 'I feel hot… can't cool off with these on' she thought moving her hands towards her pajama set.

One by one she undid her top, never losing motion on the dildo in her mouth. Her Yusei, imagination version, praising her for how good she was doing. Always taking it down to the base and back sucking on the tip every so often. As her top becomes undone and tossed onto the couch, Luna's hands move towards the front of her lingerie bra, unclamping it to reveal her modest c-cup breast, nipples erect and areola swollen for attention.

Adding to her oral motion, Luna's hands began to grope herself from the base of her breasts all the way to the tips of her nipples. Her imagination screaming at her with another Yusei appearing behind her. His hands, well actually hers, were strong and rough from all the D-Runner work he used to do with Jack and Crow. In her ear she could hear him, "I love your breasts more than Aki's sagging breasts. They are much too large for my tastes."

Her mind was racing so deep in her imagination that she never heard her brother waking up nor heard him getting a drink of water from the kitchen. He looked over the couch from the opposite end, just watching her go to town on her breasts and dildo. His eyes glued to her, erection straining within his sleepwear as he stroked himself softly. He was aware of the line crossing through his head and felt like someone should smack him with an H-Bat to pull him from his thoughts. However that was made harder by the next motion Luna was doing.

Carefully, Luna's hands went to the waist band of her pajama bottoms before pulling them down with her lacy panties. Her pussy, sopping wet and aching was now exposed to the air as she ran her right hand across the swollen red lips stroking her clit every time she came back to it. "I can't take it anymore Yusei…" she panted out in hungry lust as she raised herself up onto the couch. She was preparing to take the dildo inside her when she felt another hand touch her.

Snapping from her lust, she looked up to see her younger brother Leo standing there stroking his large dick with his right hand. His left was playing with the small amount of Fluid that Luna secreted all this time. "W-When did you wake up?!" She questioned not bothering to cover herself as her embarrassment had not yet registered.

"About twenty minutes ago when I heard you calling out Yusei's name…" he stated moving his hands to cover himself as he felt Luna's eyes glue themselves to his pelvis.

Taking her dildo in hand she began measuring it to Leo. Her eyes getting wider and filled more with lust as she was now arguing with herself. 'Well, we are two parts of one person…' she debated as another voice cut in. 'But he's your brother Luna, are you crazy?!' The voice yelled as it fell now on deft ears.

Placing the dildo down, she moves her hands over her brother's exposed tip playing with the pre-cum that formed there. "Is it painful?" She asked her brother who was blushing harder than she ever was.

"N-not really… just uncomfortable for the first time…." He replied not knowing what exactly she was asking. He assumed she meant Sex as to his knowledge, she was a virgin to where he was not thanks to Patty.

They stood in silence for who knows how long as neither one wanted to pull away from this exciting moment. It felt as though it could last forever until Luna spoke first. "Just… this one time… I'm aching that badly and you've probably deduced that I never had a boyfriend that lasted more than a month."

She said moving behind the couch with her brother. She bent down in front of him before reaching back and spreading herself. "P-please be gentle… and wear a condom…"

Hearing those words, Leo stripped completely before reaching behind a nearby couch pillow pulling out a box of lubricant condoms that he and patty stored there. "Why are those there?" Luna asked as Leo put the condom on his erection.

"P-patty suggested placing them there for this weekend… I'm just gonna replace them so she'll never know." He said placing his erection between Luna's thighs. The top curving well past her clit as he begins grinding on her. "It's gonna hurt so you know."

"I'm aware… I don't have my hymen anymore so just be gentle…" she stated as she felt Leo's tip slowly enter her. She grit her teeth almost instantly as she felt her pussy slowly stretch wider than her toy ever did. "H-how big are you?!" She questioned in panic and pain, tears streaming down her face.

"9 inches long, 3 inches wide," he replied before slamming the rest into her. Luna's voice hitched as she felt him all the way in, tears running down her face even faster.

"I- hick… I told you gentle…" she said as Leo pulled her backwards into a kiss trying to soothe her discomfort. At first she tried to pull away as this was one line she didn't want to cross but there was something about the kiss that just eased her. On top of it, Leo was not moving an inch. She could feel how hot and hard he was through the condom and her spasming insides. Upon being released from the kiss, Luna gave an experimental push back of her hips expecting pain. But there wasn't any. "I-I think I'm fine now Leo. Take me. Slowly please."

Responding to her demand, Leo slowly pulled out gritting his teeth from how tight she was despite not having a hymen. As he pulled out, the tip was left inside Luna before it was slammed back into her. Luna gasped in pleasure before groaning loudly. It was clear, Leo was reaching a new g-spot Luna had never touched before.

Slowly over and over again the motion came, the dick inside her pulling almost out and then slamming back into her harder than the last time. Her gasps were growing ever louder as she was enjoying this feeling now despite how wrong it all was. "Leo…" Luna called out as he leaned in to hear what she was going to say.

"Faster… fucking like a bitch in h-" She was cut off by the sudden but demanded speed increase of Leo. He pulled out as quickly as his hips would allow before slamming back in just as fast and hard as before. The result of this was leaving Luna a mess both in her pussy and her mind.

For who knows how long, the two engaged in forbidden acts. Lusting one another as they used condom after condom, orgasm after orgasm all throughout the night. As the sun came into view, Luna was leaning back on Leo's lap slamming her hips downward as they painted each other like beasts of desire. However in their lust one piece was now missing and out of stock in the house. The condom. Not caring anymore the two kept going trying to reach the high of orgasm for the unknown time already. "Leo, I'm cumming…" Luna moaned in a crackly voice as Leo only groaned. The warm feeling filled her to the brim as she came harder than ever before.

The end?
