Hoomerous Hentai!

DISC: Don't own Yu-Gi-Oh, not making any money, blah blah.
Set up: When Yami is outside the puzzle but not in control of the body, only Yugi can see him. ^-^

Kizuna shivered. "Does it feel cold in here to you?" She asked Yugi. He shook his head numbly, watching in horror as Yami continued to rub Kizuna's shoulders. His hands slipped forward, down her chest, until he cupped her breasts. Kizuna started.
"Uh, s-something wrong?" Yugi asked, feigning ignorance.
Kizuna shook her head. "I-I'm okay," she stammered. Yami was grinning as though all this were terribly funny. He moved from his place behind Kizuna to kneel in front of her. Yugi gritted his teeth, resisting the urge to smack Yami since he could not anyway. Yami smiled at him as he slid his hand between Kizuna's legs. She gasped; Yugi could see the sinews in Yami's arm moving, moving like they would if Yami moved his fingers. Kizuna was squirming.
Abruptly she jumto hto her feet. "I have to go home," she blurted, grabbing her bag from the table. "I don't feel well." She was out the door in a flash, leaving Yugi staring at the spot where she had been.
"Damn," Yami said. "I didn't mean to scare her off. I was just hoping to get her going a bit, you know, so you could make a move and she'd be raring to go."
Yugi clapped a hand to his face. "That was just great, Yami. She'll never come here again."
"Or she'll be back in about ten minutes," Yami said with a grin. "Thinking there’s something about you that’s so arousing, she just has to have you right now."
Yugi paused to consider this. "I doubt it," he said slowly. "She doesn't strike me as that kind of girl." Yami shrugged. Yugi glared at him for a moment, still angry, before he heaved a sigh. "I'm going to get a drink and lie down," he said, making for the kitchen.
He got himself a glass of water, chugged it down, and then heaved himself onto the couch. Yami stared down at him, grinning. Yugi was unnerved but said nothing. Silent minutes ticked by.
"Its been 8 minutes," Yami said. "She'll be back now."
"No, she won't, Yami. Not everyone is a hentai like you."
Yugi settled deeper into the couch cushions. A second later, the door flew open.
"Sorry I ran out," Kizuna gasped, out of breath. She slammed the door behind her and made for the couch, dropping to her knees beside it.
"Yugi," she panted, before pausing to catch her breath.
Yami was stifling laughs and Yugi just stared at her in shock. The top few buttons of her blouse were undone, and he could just barely see her bra. No way, he thought. She did not come back for the reason Yami thinks.
Kizuna said nothing for a moment. Yami knelt down beside her, took her wrists in his hands and led them towards her blouse. Her fingers began to work the buttons.
"I don't understand what’s gotten into me," Kizuna said, finishing the buttons and removing her shirt. "Yugi, you have no idea... I have to have you now!"
Yami's face was bright red and he was shaking with held in laughter. He moved around behind Kizuna and reached around, cupping her breasts and rubbing them gently. Kizuna moaned.
"You haven't even touched me, Yugi," she panted. "Why do I feel this way?"
Yami moved in a flash, and the next thing Yugi knew he was on the ground next to Kizuna. Yami had pulled him off the couch by his wrists, and was now leading his hands toward Kizuna.
Yami led Yugi's hands straight to Kizuna's bra clasp, undoing it, and then pushing the bra off her shoulders.
Kiss her, Yami commanded, speaking into Yugi's mind as he pushed Yugi's head forward. Kizuna and Yugi's lips met clumsily, mouths already open, tongues running over lips and teeth before meeting. Yami was still snickering lightly. He pushed a hand between Kizuna's legs, making her moan. His other hand went to her shoulder, pushing her down onto her back. He led Yugi on top of her.
Do this, he said, passing his tongue across the peak of one of Kizuna's breasts. Yugi followed suit, as Yami took his wrist and put his hand between Kizuna's legs, showing him how to touch her. Kizuna moaned and writhed beneath him.
Yami undid Yugi's belt buckle and pulled his pants down. Yugi gasped, and Kizuna did not seem to notice that his clothes seemed to strip on their own.
Yami's other hand slid between Yugi's legs. Get it all the way up, boy, he said, sounding amused. She's going to lose it if you don't give her a good fucking here soon.
Yugi gasped, crying out as Yami stroked him. When he was apparently satisfied, Yami gripped Yugi's waist and pulled him down, lower on Kizuna's body. Yami proceeded to undo the side fastenings of her skirt and toss it aside in record time. Yugi was in a near frenzy; he ripped Kizuna's panties down. Yami pushed Yugi's head between her legs.
Finish it off, he said, one hand keeping Yugi's head down as the other reached up to rub Kizuna's breasts. Yugi did as instructed, quickly, desperately. Kizuna cried out and writhed and then shudders wracked her body, she went tense, and then suddenly relaxed. Yugi stopped what he was doing.
Her relaxed state did not last. Yami teased her breasts with his tongue and reached down, slipping a finger inside her.
"Don't just lay there, Yugi," she ground out. "Take me!"
Yugi crawled upward on his elbows, and Yami moved down, gripping the backs of Kizuna's calves and hoisting her legs into the air, spread wide. He placed his hand on Yugi's lower back, and pushed him down, into Kizuna. They cried out together, and Yami wrapped Kizuna's legs around Yugi's waist before gripping Yugi around the ribcage and getting him into a fast rhythm. When he was satisfied that Yugi could actually handle it for himself, he moved away, took a seat against the wall, and watched the end of the show.
Yugi barely noticed the help Yami gave him, or when Yami moved away. He was too busy keeping up with the rhythm Yami had set for him, thrusting hard and fast into Kizuna. She was writhing, raking her nails down Yugi's back and crying out his name. Yami laughed; if she only knew whose name she should really be screaming.
Yami began to be surprised by how long Yugi was lasting. He was still going fast and hard into Kizuna, and heies ies were just as loud. Yami put his head on his fist and kept watching.
Finally, Yugi cried out and collapsed atop Kizuna. She stopped writhing, merely letting her hands rest on his lower back. Neither of them moved for some time. Yami rolled his eyes.
Don't lie there like a dead weight, Yami said to Yugi. Get off her.
For a moment Yugi did not respond, and then he slowly lifted himself up. Kizuna would not meet his gaze as he rose off her.
"Well," Yugi said awkwardly, pulling up his pants.
Kizuna turned her eyes to him finally. "Yugi," she breathed. "You're incredible."
Yami snorted.
Incredible, Yami said sarcastically. If she wants incredible, you should let me have a go at her when I'm in control of our body.
Yugi shook his head. No way, he said, obviously proud of himself, though he had no right to be. I think she's mine now. Kizuna rose off the floor, pulled up her panties and began retrieving her scattered clothing articles.
Yami set his jaw angrily and stared at Yugi.
"Wow, Yugi," Kizuna was saying. "I had no idea you were so... skilled." She tittered. "I don't know what came over me, but it was with good reason. You're amazing. This could be bad for your education; this is all I'll ever want to do with you, Yugi."
Yami rolled his eyes and snorted repeatedly during this speech. Minutes had ticked by. By the way, Yami said casually. Your grampa should be getting home right about... now.
"Shit!" Yugi said aloud. Kizuna was startled, but then she noticed the time.
"Shit!" She echoed, throwing on her clothes. "Oh shit, Yugi we almost got caught. I better let myself out the back door." She ran towards the back of the house but then stopped, rushed back at Yugi and planted a deep kiss on his lips. "I think we need to have more than just two study sessions a week from now on, don't you?" She purred suggestively, and then she raced off. The back door slammed a second before the front door opened.
Yugi was standing in the middle of the room with belt unbuckled and his hair disheveled. A bright red blush settled onto his cheeks as Grampa took in the scene.
Sugoroku walked slowly into the room, letting the door fall shut behind him. He stood before Yugi for a few seconds eyeing him steadily.
"Yugi," he said gravely. "I smell pussy."
"Well, uh," Yugi stammered, but before he could explain, his grandfather clapped him jovially on the back.
"Good for you, boy!" He said in an excited tone. "I was starting to worry about you! So tell me about her! Does she have a nice bust?"
"Uhm," Yugi said, his blush deepening. "Yeah.." he said slowly.
"Great!" Grampa exclaimed. "When do I get to meet her?" He winked at Yugi.
"Grampa," Yugi groaned. "Please don't act like this. You're disgusting."
Grampa huffed. "Well, excuse an old man for wanting some eye candy. And here I was so happy for you, getting your first piece of ass, and look how you treat me." Grampa pouted.

Abrupt ending = unfinished. It wasn't imporant anyway. Chapter 2 coming soon! =^.^=
