**Caging Day**
"Are you sure about this?" Lily asked, her bright blue eyes locked on mine as she sat cross-legged on the couch next to me, her long straw-blond hair falling forwards over her face.
"Of course, I love you Lily" I said, and with a loud click, snapped the lock shut on a metal chastity cage.
Lily flinched at the sound and let out a quiet gasp, as though she were the one who had just surrendered control of her body. I let go of the lock, and brought my hand up to Lily's face, brushing her hair back, as I held back of her neck and kissed her.
"Aww, you two are so cute" Zoe said, clasping her hands together.
Lily broke off our kiss and turned away, flustered. Zoe stood up from her seat and walked over to me. She gave my cage a firm tug and checked the lock, making sure everything was secure. She gave me a dirty grin when she saw that I was already starting to strain in the cage, then plopped down on the couch next to Lily.
"Does it feel ok? Does it hurt?" Lily asked quietly. I reassured her everything was ok, and started to reach for my pants. Zoe reached across Lily's lap and grabbed my hand, stopping me.
"Your body belongs to Lily now, you don't get to cover it up unless she asks you to." Zoe said in a teasing voice. "In fact, take off your shirt too, and throw your clothes in the other room".
Lily let out a small sound, but Zoe pressed her finger to Lily's lips, silencing her.
I took off my shirt, and threw it and my pants out of the room, then walked back to the couch, doing my best not to feel self conscious. As I walked the feeling of the cage pressing on my restrained member was enough to get me throbbing, much to my embarrassment. I resisted the urge to cover myself, knowing that I had no right to hide my body now that it no longer belonged to me.
Lily ran her hand along my chest and abs, almost reaching the cage, but hesitating before reaching it, until Zoe grabbed Lily's hand and forced it down to my cage. I was hornier than I had ever felt before in my life, but the pressure from the cage was unrelenting, and I had no hope of getting even a little hard. As Zoe ran Lily's hand over the length of my caged shaft, and gently down to my balls, I thought I would go insane with desire. I did my best not to look too uncomfortable though, and gave Lily a small kiss, my arm lightly brushing across her breast as I reached up to touch her face.
"It looks so tight, are you sure its the right size?" Lily asked, drawing her hand away.
"Its perfect, I'm just excited to be doing this for you" I reassured her, as Zoe rolled her eyes.
"Oh yeah you sure are excited alright" Zoe said with a smirk, making Lily blush.
I put arm around Lily and pulled her close to me, her hair brushing my bare chest, as Zoe stood in front of us and went over the rules one more time.
Although I had been nervous ever since Zoe had suggested this, I felt a sense of relief now that the I had committed. Whatever happened now was out of my control, literally. Lily gripped my hand and gave me a small smile, and I thought back to how I had ended up here.
**Backstory**
I had only been dating Lily for two months, but we had known each other for years through mutual friends, so it felt like I had been with her much longer. We already knew everything there was to know about each other, and knew we belonged together. It had never been any secret that we were attracted to each other, but for years my many attempts to ask her out had never resulted in more than her blushing turning her head away. In the end it was Lily's best friend and roommate Zoe who convinced her to let me take her out on a date. It didn't take long before we became inseparable. We were the perfect couple, and everyone who knew us already knew we would end up together forever. What nobody else knew, other than Zoe, was that we had never had sex.
Lily had always been a quiet girl with a sweet voice and a gentle temperament. Although she was only 21 years old she had already gotten her bachelors degree, and was in grad school studying a branch of mathematics I had never quite been able to wrap my head around. When she wasn't studying, she spent most of her free time reading trashy romance novels, her guilty pleasure. She had pale blue eyes, and strawberry blond hair which she kept long with rough fringed bangs framing her delicate face. She was reasonably tall at 5'8", but her slim, narrow frame and tendency to keep her head down as she walked made her disappear in crowds. Her breasts were small, barely filling out an A cup, but firm and perfectly round. Although she was elegant and beautiful, she never sought attention and rarely caught the eye of men. Her clothes were always modest, and practical and she almost never wore makeup. Lily had always been too shy to date, and looked like she would die of embarrassment any time Zoe had managed to drag her out of their apartment to go to a party. Despite her total lack of a social life, I had always suspected that deep down she craved affection. Once I ran into her while out on a run, shirtless and sweaty, and for a moment she was unable to hide the glimmer of hunger in her eyes as her gaze lingered over my abs.
