It was impossible to get Seto and her big brother to get along. Seto made it obvious that he couldn’t tolerate him. This, however, did nothing to deter Shizuka. She loved the both of them very much so they would just have to deal. Tonight would be another night of playing mediator between the two boys. Anzu and Mai had no idea how she managed.

It was quite easy, in all honesty.

A small moan passed Shizuka’s lips as she sank onto Seto’s cock. Her wet heat enveloped his shaft. The sensation made the normally stoic man shudder and mutter under his breath. Sweet, sweet friction. Seto’s hands placed themselves on her thighs and held her in place. He longed to just slam her down onto the entirety of his prick but held back on his desires. He knew better. He also knew that Shizuka could take it but... his fellow partner would flip out.

Katsuya huffed as he buried his face in the crook of his sister’s neck. His fluffy blond hair contrasted against the warm brown of Shizuka’s. Seto bit back a remark about not wanting to see Jounouchi for his girlfriend’s sake. It was a big ask of him but he managed. He loved Shizuka more than he disliked the blond.

Katsuya, likewise, kept any remarks to himself when he accidentally locked eyes with the brunet. His hands ran from her shoulders and down her sides until they reached her hips. His cock throbbed as he felt the curves of his sister’s body under his touch. “You ready for me, Shizuka?”

Shizuka nodded. She turned towards him and gave him a peck on the corner of his mouth. “Yeah, keep going.”

He leaned over to kiss her properly. One hand slipped down her hips and cupped her ass before parting her pert cheeks. “Get ready,” he breathed. His cock prodded her tight entrance once, twice, three times before finally getting a purchase on her. A hiss was shared between the siblings as he pushed past the tight ring and was properly inside.

She felt so tight. She always did whenever they got together with Seto.

The sensation of Seto’s cock so close to his, just barely separated by a thin wall of soft flesh, always left Katsuya conflicted. It felt good. Really good. But couldn’t it have been with literally anyone else?

“Fuck,” Katsuya muttered. “You feel so good.”

“Y-you do too, Big Brother...” She mewled before leaning forward to kiss the other man on the lips. “You do too, Seto. The both of you can move now...”

Seto’s nails dug into her soft thighs as Katsuya moved his to her heaving breasts. Fingers sank into soft flesh. Shizuka’s eyes snapped open as her brother pulled out only to slam himself forward. Seto chuckled.

“So it’s fine for you to get rough with her, mutt?” he muttered as he thrust upward and made the girl gasp out. “What happened to ‘treating your little sister right’?”

Katsuya didn’t have a response, he simply growled under his breath and tried to focus on the sensation of Shizuka around his fat cock. His fingers found her nipples and gave them a pinch. Electricity pulsed through her body. A high-pitched moan tore itself from her throat as she clenched around both boys. Seto hissed as Katsuya let out a long, drawn-out moan. The brunet grimaced as he felt the blond twitch and throb through her walls. They were so close. Too close. If he had his way, he would just have Shizuka all to himself... but that wasn’t what she wanted. She loved both of them and whatever she wanted, she got.

Their thrusts were uneven and out of sync at first. The sound of sweaty flesh smacking against sweaty flesh filled the air as did the heady scent of sex. Shizuka’s arousal dripped down Seto’s shaft and stained the upholstery below. Soon, the boys found a rhythm. Whenever Seto would pull out, Katsuya would push in, and vice versa. It was a breathless pace that Shizuka could barely handle but she absolutely wanted more.

Shizuka was the first to cum. Violent tremors wracked her body. Her back arched against her brother’s back as he clung to her, murmuring sweet nothings into her ear. Seto grumbled before sitting up to kiss her on the other side of her neck. Murmurs about how nice and tight she felt around his cock, how he was going to make her his, and how she belonged to him drifted through her mind. She cried out as the two most important men in her life showered her with praise. Their thrusts kept going, less powerful than before, but they still kept going.

Katsuya finished second much to Seto’s amusement. He buried his face in Shizuka’s hair as he completely sheathed himself inside of her ass. His cock throbbed as he panted and his cum flooded her insides. It didn’t take Seto long to finish. His cum splattered against Shizuka’s defenseless womb. The thought of getting her pregnant with his child made him shudder.

Panting, the siblings collapsed onto Seto who did nothing to move them. Somehow, the combined weight of the two was comforting... Though, he could do without Katsuya.
