Still asking stupid questions!

Issei didn't even need to think about it. He rushed right up to her like a lost puppy. "Hell yeah!" he grinned, and Rias giggled, pulling him into the bathroom. He quickly went to the tub, and turned on the showerhead, waiting until the water reached optimal temperature before they stepped in. "...we might be in here for a bit, so I wish that the hot water will last long enough for us to have some fun in here," he then stated.

"Done, Master!" Rias snapped her fingers with a smirk. "Would you like anything else before we start cleaning up?"

He took a moment to think about it as the water cascaded down on them. She really looked amazing, and the water droplets glistening and dripping down her nude form only added to her allure. "...damn, I could go for a kiss from you right now..." he replied. She immediately stepped up to him, and planted her lips directly on his, moaning in delight as he reached down and groped her ass.

She really enjoyed the contact, not just because she felt good, but because she knew he was enjoying it too. "Mmmnh," she crooned as she broke the kiss, pressing her wet backside into his hands some more. "Master... Remember how I used my boobs to clean your back, back in the club shower?"

"Yeah?" he asked, wondering where she was going with that question, and she grinned.

"May I clean your whole body in that manner this time?" she purred, hoping to be allowed to serve him in such a way with her best assets.

He blushed heavily at the idea of Rias using her wonderful boobs as a loofah on his whole body, and nodded immediately. "O-of course, go for it!" he stammered out.

She beamed at him as she immediately upturned the soap bottle over her chest, and let it drizzle out, before caressing her own tits to get them all sudsy. She then pressed her chest against his, grabbing his shoulders as she did, and started sliding their torsos together. As she did so, she never once broke eye contact with him.

"Unh..." he moaned, growing hard again at her efforts as her chest glided along his body, with her pressing her mammaries against it forcefully to scrub. It was certainly not an efficient way to clean him... But damn if it wasn't hot as hell!

"Do you like this, Master?" she asked, pressing him against the shower wall before kneeling and lifting up his foot to rub her boobs against the sole.

"...yeah, definitely," he nodded as she repeated the process with his other foot. She continued cleaning his body, reapplying soap to her breasts as needed, before finally stepping away, letting the water cascade down her body, rinsing the soap off of her.

"...oops... I seem to have gotten you hard again," she teased, pointing down at his crotch, and sure enough, he was once again at full mast.

"...you do have that effect," he noted, blushing as he rubbed the back of his neck.
