I felt the coolness of the soap, and then the slipperiness it provided. Kris, seemed to as well; she grabbed the corner of the shower door, lifted her head and started moving up and down, increasing the pressure of her skin against mine. I looked down and saw my foreskin moving backwards and forwards so smoothly it could have been manipulated by my own hands.
“Fucking yes,” Kris announced. I guessed things were progressing ok so far. I leant back and twisted my hand around so I could trace it down the small of her back. Then I progressed further, rubbing the shower gel around the top of her buttocks, and then venturing further down, applying delicate pressure all the way until I reached the delicate bud of her anus. As my finger circled this gently but persistently, Kris subtly changed her position, raising one hand higher, lowering the other to her own sex, and readjusting the position of her feet slightly so she could lower her ass, allowing me easier entry.
I slowly pushed in my lubricated finger, relishing every one of Kris’s high-pitched quick breaths. She didn’t move at all as I pushed it in, but as I gently started pulling it out she slowly rotated her behind and pushed backwards, trying to hold onto my finger for as long as possible, while all the while her own clitoral stimulation increased in vigour. Her own hand was buried deep in her crotch from the front, and just from the movements I could see from the top of her arm she was working herself exceptionally enthusiastically.
I removed my finger entirely, and then reached again for the shower gel. I flipped the lid with one hand, cupped the other underneath my fully-engorged cock as I squeezed a large amount over it, catching the rest before rubbing it into my member.
“Are you ok with this?” I asked nervously.
“Tell me what you’re gong to do,” she gasped.
As I caressed the curve of her back with one hand, the other was on my heavily lubricated penis, guiding it to her asshole.
“Well, first I was going to do this.” I pulled my foreskin fully back and, looking down, guided the dark skin to her tight, taboo hole.
“Yeah?” I pushed, feeling a pressure I’d not experienced before. “Tell me what you’re doing, for fuck’s sake.” The resistance, despite all the lubrication, was surprisingly unyielding, but Kris’s harsh tone spurred me on. I leaned hard into her, and felt that tight hole succumb.
“I’m fucking your ass,” I hissed, slowly pushing further and further in. I searched for other words, but couldn’t think of anything clichéd or ridiculous. “I’m fucking you; I’m fucking your asshole.”
I could have been saying anything; Kris was gasping so loudly it was almost an inverted scream. Her hand left her snatch and it went to the shower wall with the other. She was in the stance of someone about to be searched.
I pushed in until I couldn’t anymore. “Don’t move, for crying out loud don’t move,” said Kris. I didn’t need to. Held there in place as the warm rain of the shower fell down on us, I felt the warmth grow up between my legs, all around my groin, and not moving, fastened there in the stretched asshole of the woman I thought I loved, my seed coursed vigorously into her as we both shouted our orgasm.
