I ambled into the bathroom bleary-eyed and fumbled with the sink faucet. I rubbed cold water into my eyes and prepared myself for a much needed day off. I sighed deeply and considered what PC game I was going to play first.
"Yeah you gotta see this fucking thing..." My thoughts were interrupted by muffled conversation trickling from my sister's room. "...I don't know where he got it..."
Our bedrooms were connected by a neat little jack and jill bathroom, doors on opposing sides, so I could sometimes hear her thumping music or one side of her phone conversations faintly through the door when I was taking a piss. A small keyhole below the doorknob allowed a certain amount of sound to seep through.
"Yeah I'll find a way..." the conversation piqued my interest as I began to gather what she was talking about with her girlfriend. "He's fucking messy... he probably just leaves it laying out somewhere."
One corner of my mouth turned up.
"Yeah it's big" she said with a giggle. "yeah yeah I know what you like, you whore."
I shivered in delight.
She was talking to her friend about my cock. Rather, my dildo. My very, very realistic and "cum-filled" dildo.
The implications of their conversation began to materialize in my mind.
"I don't even know, girl... I always knew he was a sick little fuck. I just don't even care as long as we can..." Her voice trailed off as she began to whisper.
"Ok I'll see you in a few," I could barely hear after a few moments of silence.
I could only make assumptions.
I left the bathroom silently, clicking the door shut behind me.
I looked over at my desk where the small black box sat.
My dick began to swell as my gears turned.
I looked at my bathroom door with hope. Hope that I'd heard her right. Hope that I was right about what might happen in mere minutes.
I popped open the small black box and pulled both of the glowing latex-like rings out as my plan began to materialize.
I quickly pushed my boxers down and my half-hard cock flipped past the elastic band.
Holding one ring in my flat palm, I slid the other one carefully over my thickening dick and reveled once again as my cock appeared in my outstretched hand.
I held it carefully and looked down at my balls. I thought about it for a moment and decided she wouldn't remember what it looked like yesterday, the stupid bitch. So I reached down and stretched the flexible material over my sack, watching my balls materialize off the side of my hand and hang from my shaft.
I shivered with delight.
I pulled my boxers back up and gripped my shaft gently, feeling my hand squeeze it. I grazed my fingertips over my smoothly shaved balls. I shuddered as it thickened further.
I went into the bathroom and shut the door behind me allowing it to click against the strike plate loudly. I wanted her to know I was in here. I had a plan.
I looked at my cock. I looked into the mirror and saw myself with my cock in my hand. I blushed with shame. I was truly embarrassed, but only for a moment.
I allowed a bit of saliva to well into my mouth and I spit on my tip audibly, glancing at the door to my sister's bedroom hoping she'd heard.
I hesitated for only a final moment before I pushed my tip into my mouth and sucked noisily. My knees nearly buckled when I felt the nubbly texture of my wet tongue glide across my extremely sensitive frenulum and my lips slip over the pronounced ridge of my circumcised head. I held it in my mouth as I flicked my tongue side to side against the sensitive skin under the head. It grew quickly and the head swelled in my mouth.
I sucked it loudly. I wanted to make sure she heard. I made sure to lewdly slurp with wet suction as my lips slipped over the ridge of my swollen head each time I slid my cock into my mouth. A sickly pop echoed off the bathroom walls with each thrust.
It felt incredible. It was gross. I accidentally glanced up at the mirror at myself. I saw my own lips wrapped around my shaft and my cheeks undulate with the disgusting movements of my tongue. I blushed fiercely, my cheeks flushing with redness as I looked away quickly in shame. I didn't stop. I continued my loud self-molestation with purpose.
Eventually I decided that there was no way Jess couldn't hear me and I pulled my "dildo" from my mouth with a loud pop.
I unceremoniously threw it into the drawer on my side of the bathroom with a thud and shut it loudly. I left the bathroom and shut the door behind me.
A bit of panic shot through me as the realization of what I'd just done began to set in. If my assumptions were right about what I'd just heard Jess talking about, it means I'd just surrendered a part of myself to the whims of my sister and her cunty friend.
A knot formed in my stomach.
I turned around and reached for the bathroom door once again.
The doorbell rang. My hand flinched away.
I weighed the possibilities quickly.
I soon heard the sing-songy voice of my sister's bestie, Amber, from downstairs. That sealed the deal. Amber was just about as banging hot as my sister. Gorgeous face with luscious pouty lips, huge tits that spilled out of her sweaty sports bra when they came back from the gym together, big round ass cheeks, usually clad by tight form-fitting yoga pants. Equally cunty at times though.
I heard them both thump their way upstairs and past my bedroom door, excited whispers being passed between them.
Soon after, my sister stumbled into the bathroom from her side. I listened.
"Yeah he was just in here with it." She half whispered, half giggled. "I heard his drawer- Yeah here it is. Oh my god"
The feeling of her delicate fingers once again wrapping around my sensitive shaft sent me falling into my desk chair and my eyes fluttering.
"Look at this fucking thing, dude" She whispered loudly.
"Holy shit... Why does he have this?" Her stupid friend giggled.
"I don't even know. It sounded like he was- EW It's all fucking wet!" Jess blurted.
The bathroom faucet hissed and I was shocked by the intense feeling of cold water being splashed across my shaft. The feeling of them both rubbing the length, the head, sliding their fingers across my balls while the cold water washed over my cock threatened to send my cum prematurely spurting into the sink.
The feeling was surreal. I reclined back in my desk chair with my eyes closed as I envisioned them both lovingly caressing my swollen flesh 10 feet away from my body.
The raspy feeling of the towel was less nice, but it was brief.
They giggled and bounded back into her room, shutting and locking the door behind them.
I felt them fingering it with curiosity, tracing their fingers up and down the veins, around the ridge of the head, across my flared piss hole, along the smooth flesh of my sack. I was in heaven. I was still nervous. I wasn't sure what they were capable of. I was putting a lot of unspoken trust in their motivations.
I opened my eyes with realization and silently crept into the bathroom on wobbling legs. I knelt down at my sister's door and peered through to small keyhole. They were both on their knees in the middle of her room, bouncing with glee on the balls of their feet.
"I can actually feel it throbbing..." Amber said quietly, holding it up, looking at it with reverence.
"What, really!?" My sister grabbed it from her, my balls bounding to the side, and squeezed it, looking at it with thought. "Holy shit you're right... It's so fucking realistic... Look there's even precum inside that comes out when you play with it..."
They ran their fingers across the tip and dragged the slick liquid around on the head. Each time one of them gripped it or fingered it with curiosity, my entire pelvis lurched with white-hot pleasure. The sheer taboo of the act only served to send additional burning jolts of bliss through me.
"Wait a second!" Amber spoke with realization. She grabbed my cock from my sister. "This ring..."
She glanced up at the bathroom door briefly. The keyhole was tiny, so she couldn't see me, but she looked right at me like she suddenly had x-ray vision.
"This is-" She stopped herself. She glanced at the door one more time.
