Very hot!

Issei and Kiba arrived at the pool, and proceeded to enter the guy's locker room to change into simple swim trunks. "...heh, not bad," Kiba remarked, glancing towards Issei from the side, and taking on a teasing smile. "No wonder Prez is so satisfied with you as her Master..."

"H-hey, don't peek!" Issei flushed, turning away, and Kiba laughed a bit. Issei took a moment to wonder if Kiba was into dudes at all. Not that he judged, but he hoped Kiba didn't start flirting with him regardless, as he wasn't interested. Though he did admit, the compliment to his manhood, which was by no means huge, but still a decent size, did stroke his ego a bit.

They stepped out, grabbing the pool skimmers, and started getting the leaves out. "Oi, ready for the show?" Raynare's voice called from the inside of the girl's locker room.

"...alright, yeah!" Issei nodded, practically drooling. True to form, Raynare exited first. She was wearing a purple micro bikini. As in, she had only tiny triangles on her nipples, and a thin strip covering her pussy.

Issei froze, staring as Raynare smirked, and gave him a twirl, showcasing that the string of the bikini bottoms rode up her ass. Issei let a trickle of blood escape his nose. "Heh, think this is daring, wait until you see Rias's," Raynare smirked, stepping aside to let Xenovia exit next.

Issei drooled slightly at that sight. Xenovia was wearing a rather simple green bikini, with multiple thin strings serving as the waistband of her bottoms, and connecting the cloth over her boobs. Not the most revealing bikini, but enticing nonetheless. "...should I twirl too?" Xenovia asked Raynare, who nodded.

"Go for it," Raynare answered, and Xenovia obliged. Asia stepped out next, wearing a lime green two piece racing swimsuit.

"How's this, Master?" Asia gave a slightly awkward, yet still flirty wink as she attempted a sultry pose with one hip jutted out.

"... incredible..." Issei sighed in absolute delight. Akeno was the next out, and she was wearing a small, dark red bikini. Bigger than Raynare's, but definitely still extremely revealing.

"How about this?" Akeno purred, turning around to show that the bikini bottoms rode low enough to expose a nice bit of ass crack. She turned a sly look over her shoulder at Issei, and crossed her arms under her bust as she gave her backside a nice wiggle for his enjoyment.

"...oh God, if Rias turns it up much more, I might actually pass out from my dick taking up too much of my blood supply," Issei gushed a bit. Indeed, his erection was straining at his boxers, like it wanted to tear free and drag him right to the bevy of babes before him.

"Challenge accepted~!" Rias called cheerfully from the locker room, before sauntering out. Issei.EXE proceeded to crash abruptly at the glint of her own swimsuit... She had certainly gotten creative with it. She was wearing a bunch of thin, silvery strings, with only glimmering bits of jewelry covering up the important bits. It was roughly the same size as Raynare's micro bikini, but the gleam of the gemstones were somehow so much more suggestive (Think the Fortune swimsuit from Dead or Alive). Rias let a radiant grin overtake her face at Issei's sheer adoration at the sight of her like that, and she gave a twirl for him.

"...holy shit... I could die happy..." Issei breathed, barely daring to move, earning giggles from the girls, aside from Koneko, who just gave a tired sigh as she exited herself, wearing a one piece school swimsuit, hoping at least that she wouldn't get ogled much by Issei with everyone else being so exposed.
