In her ass

Victor stepped into the shower stall, and immediately realized that he wasn't ready for such cold water. He tried to focus on the unnaturally gorgeous woman in front of him, but his cock was responding to the cold as most do, which was not the right answer to this quiz.

"I got you," Naomi said. She positioned herself between Victor and the water. She took up a small orange bottle, and squeezed some onto her hand. She rubbed it onto his cock.

"What is that?" he said.

"Oil," she replied. "Oh, dammit. I should have said 'ketchup' or something. That would have be hysterical. But whatever. It's oil. It's a specific oil that lubricates and provides an almost electrical stimulation when friction is applied. It's particularly effective during sex, and even more so when the guy is going to fuck me in the ass."

Victor held his breath.

"Like you are."

She continued to massage the oil into the skin of his rapidly stiffening cock. She looked straight into his eyes, and spoke more softly. "You met me about five minutes ago, you think I'm some crazy bitch with a rando fetish, and you're going to get rock fucking hard right now and slam your cock straight into my virgin asshole." She was right about most of that including the part where he was getting rock fucking hard. Her dirty talk had turned intense, and whatever the recipe was, the oil plus the talking plus the girl plus the whatever, he felt he was about to explode.

Naomi knew it too. She whispered once again, "I'm going to turn now, and you're in charge of this moment. You have five seconds to completely plow my tight asshole before I will fucking step on your foot, knee you in the dick, and you'll never see me again."

She paused and then exploded with laughter. "Holy shit, I don't know what the fuck I'm talking about sometimes! Don't worry -- that stuff isn't true." She paused, then continued, "I'll give you more than five seconds."

She turned around and bent over. Victor gave his cock two more quick pulls, but he was confident in the moment. Did she really say she had a virgin asshole? This is going to fucking kill her, he thought. Of course, with everything else she's said, who the fuck knows what's real? He held her ass with his left hand, and with his right, steered toward her asshole.

"Don't fucking ease it in you pussy. Just fucking stab me."

An instruction is an instruction, he thought, and placing the tip of his cock on her asshole, he held her hips with both hands, and thrust forward. His dick easily penetrated the outer muscle, and the oil gave enough lubrication for his first thrust to take his cock pretty far. Naomi shrieked in the moment, but did nothing to pull off of him. He held his position deep inside her for two, maybe three seconds, then withdrew. He pulled back only far enough so that the head remained inside, and then pushed forward again. Naomi shrieked again, pitched a bit lower, and lasting a little less time.

Victor aimed to establish a rhythm, and with each fresh thrust, Naomi's noises evolved from shrieks to moans to murmurs. Once Victor was comfortably settled into a pattern, he moved one hand off her hip and underneath his cock to finger her pussy. When he began this, he could feel Naomi's breathing change, and she wriggled her hips against both the fingers in her pussy and the cock in her ass.

Victor became aware of the oil. She was right. It felt like a mild tingle of actual electricity on his cock. He had touched raw batteries from time to time, and the slight jolt of electricity from that was similar. His cock vibrated, and with each new penetration, he felt a slightly different pattern of what he could only describe as lightning-like along the shaft of his cock.

Naomi was in ecstasy over this. She also felt the electricity in her asshole, and although her virgin comment wasn't true, it had been a little while since she'd had anal sex, and her butthole had tightened up quite a bit. Maybe it didn't feel quite like the first time, but it was pretty amazing nonetheless.

Victor kept pounding her ass for a while, once reaching into the water to splash some on his face. Occasionally, his rhythm would slow, and he would pause inside her and pulse the muscles. Naomi felt that in her ass, and loved it. She sighed each time, and smiled.

His breathing got faster as he pumped and pumped. Before too much longer, he was either going to come, or need to change positions.
