I fucked her until our bodies were sticky with sweat and I worried one of us would overheat if I didn’t put space between us. She frowned, her face pouting and announcing she was disappointed I had pulled away, but when I sat up and cooled off, the craving for control returned.

“On your stomach,” I said, my tone firm.

Gone was her pouting expression. I only got a flash of her excited look before she rolled over and arched up, presenting her flawless ass to me.

“Hands behind your back.” My words were spoken softly, but carried weight. She complied, crossing her wrists in the small of her back. The black cuffs looked good against her pale skin. I grabbed one of the clasps and snapped it around the ring on the other, turning them into handcuffs. “Fuck, you look amazing.”

I snatched up the bottle of lube I’d placed on the nightstand, along with the trainer plug Joseph had encouraged me to buy. When I’d mentioned how neither of us had tried anal before, he’d said the best chance for success was “lots of prep, and lots of lube.”

The silky lube was thick and cold as I spread it over the toy. She had one side of her face flat against the mattress and watched me over her shoulder.

I laid my free hand on her ass. “Ready?”

She nodded.

There was a sharp intake of breath from her as I eased the plug inside. Once I had it all the way to the base, I squeezed her thigh. “Okay?”

“Yeah. It feels . . . weird.”

I moved to kneel between her legs and guided her to lift her hips. Since her arms were bound behind her back, she supported herself on her chest. I teased the tip of my cock against her entrance, and she wiggled, trying to line us up so I would slide inside.

“Fuck,” we said at the same time. With the plug in her ass, her pussy was even tighter, and I groaned. One thrust. Another. Ruby moaned and pressed her face deeper into the bed.

“It feels good,” she said.

I couldn’t agree more. I was aching to drive harder and find my release. My cock had been uncomfortably hard most of the night, and was reaching the limit on not being a selfish prick. My body threatened mutiny. Every molecule in me craved to come.

She rocked her hips, pumping on me like she needed control. “I want it.” She moved faster, beating against me. She amended and clarified. “I need it . . . in my ass. Please. Give it to me.”

I exhaled like someone squeezed all the air from my lungs. She was so unbelievably hot. I slowed my tempo to a stop and pulled out of her. She seemed anxious, and the position she was in didn’t look all that comfortable, so I leaned over the edge of the bed and grabbed two pillows. I wedged them beneath her hips and stomach, giving her more support.

The plug thumped to the floor after I slowly extracted it from her. More lube. First, I squeezed a good amount onto her, and then I smeared a handful over myself. The smooth, slick glide of my fingers over my dick felt good, but I had a dirtier desire.

No woman I’d ever been with had been up for anal, and maybe that was part of the appeal. It was forbidden, and like a stereotypical male, that made me curious and interested. This same reverse psychology was another reason I’d put the final paragraph into our partnership agreement. I was hopeful by taking a normal relationship off the table, it’d make Ruby hungry for it.

I peeled her backside apart and prodded, letting my dick slide around in the liquid. It wasn’t sticky, but thick and slippery, and it felt almost luxurious.

Her breathing was short and rapid, her shoulders tense. I had to be feeling some of her same nerves, just the flip side. I didn’t want to hurt her. If she didn’t enjoy it, I wasn’t going to either.

I clamped a hand around the base of my dick and found where I wanted to go, and slowly began to press at the tight spot. The lube made me slide the head inside, but her fingers reached out for me, touching my stomach and asking me to wait.

“Oh, fuck,” she cried. “Go slow.”

I moved at a snail’s pace, focusing in on every stuttering breath she took and each tiny movement she made. Jesus Fucking Christ, her body gripped me like a tourniquet. It was so tight, I clenched my teeth together.

I barely moved as a bead of sweat rolled down my back. Her hands relaxed a little as I drew backward, and then eased forward. In. Out. A tiny bit more on each pass. Her eyes were closed, at least the one I could see, and her face was pure concentration. Perhaps I could distract her as she got used to the sensation.

“Where’s my cock right now, Ruby?”

She shuddered around me, but it seemed to be a good one. “Oh my God.”

“Tell me. Where is it?”

“It’s in my ass, fucking me.”

I throbbed and my balls tightened. Not yet, just wait. I gazed down and watched as my glistening cock disappeared inside her. So, very, hot. It was a tiny miracle I didn’t come just at the sight of it.

I was almost all the way in, and it seemed that every gentle thrust I gave her loosened her up and allowed me to push further. “That’s it,” I whispered. “Take it deep.”
