Though no one else was at my house, Wren waited until we were upstairs and inside my room, with the door closed behind us, before she revealed her new purchase.

I curiously watched as she reached into her purse to withdraw the sex toy she'd bought. It was her first, and she was quite proud of herself for visiting a local shop and selecting the bullet vibrator. Staring down at the object in her palm, I wasn't exactly impressed. "That's it?"

"It's little, but it's really powerful," Wren explained. "At least, that's what the lady at the store said. Of course, I haven't had a chance to try it out yet." The toy couldn't have been more than a few inches long. Covered in pink silicone, it had a rounded tip. I noticed Wren was breathing a little faster when she turned it on. "It's ready to go!"

The vibrator's motor hummed away. Shifting my weight from one foot to the other, I tried to sound casual. "I, uh, hope it works for you."

"I can't wait to use it!" Wren flashed one of her gorgeous smiles at me. "Thanks for letting me come over for some private time, Logan."

I didn't need to be told how weird it was that my eighteen-year-old friend was in my bedroom, preparing to masturbate with her new toy. Even as the situation was unfolding, it felt surreal to me. But Wren and I had been friends forever, and she trusted me more than anyone else. She was also envious of the fact that I had plenty of privacy. She, on the other hand, had to share a bedroom with her sister. "She's always around!" Wren had complained to me on the phone. "And I'm forbidden from locking her out, even for a few minutes. I have no time to myself."

On that particular Saturday, my parents were out of town, so I invited her over to use my room. She'd agreed without hesitation; apparently, she didn't find the situation strange at all. I was happy to be able to help her out, and happier to be the one she turned to. Secretly, I was a little afraid she'd soon leave me behind. Though I was a few weeks older, Wren had always seemed far more mature. I was the quiet guy obsessed with graphic novels and astronomy, while she was way... cooler.

Not once had my parents ever expressed concern about me hanging out with Wren, even when they weren't home. They'd never say it out loud, but they probably figured she couldn't possibly see me as more than a friend. With light brown hair and eyes almost the same color, I was average in height and build, easily overlooked in a crowd. But Wren? She was beautiful. Her brown hair cascaded down to the small of her back, and her blue eyes were large and expressive. And her body? Well, I tried not to dwell too long on her perfect figure.

I'd had a couple of girlfriends, and Wren had dated several guys during senior year. Plenty more made it clear they wanted to be with her. Yet despite her past boyfriends, she'd recently confided in me that she was still a virgin. "I didn't trust any of them enough," she told me. "I worried they'd turn around and tell all their friends about everything we did." 

Again, it came back to trust, and I wanted her to know she could always trust me. Now, I nodded toward my bed. Because I knew she'd be using it, I'd made it up with clean sheets; I wanted everything to be perfect for her "private time."

"Make yourself comfortable," I told her, still trying to play it cool. Was I blushing from the thought of her in my bed? Good God, I hoped not. "I'll be downstairs if you need anything." As I spoke, I tried not to let my imagination stray into X-rated territory. Later? I'd be lying between those sheets, jerking off while I fantasized about what Wren had done. But at that moment, it was important to hide the fact that the idea of her masturbating made me horny as hell.

"Wait," she said when I started for the door. I paused, looking at her expectantly. "You don't have to go," she went on with a shy smile. "It feels weird, kicking you out of your own room."

"You're not," I tried to assure her. "I just want to give you privacy."

Wren's gaze drifted to my desk chair. "It might be fun if you stayed. Just, um, look away while I take off my panties."

I wondered if she heard my sharp intake of breath. My stare swept over her summer dress, which accentuated her breasts. "Of course," I blurted out. If Wren was willing to let me stay, there was no chance I'd turn down that offer! I knew she'd be mostly under the covers while she played, but simply seeing her face, and hearing the hum of that toy...

I hurried to my desk, hoping she hadn't caught sight of my boner. Sitting down in the chair, I faced away from the bed. My dick was already uncomfortably hard beneath my shorts. Behind me, Wren moved around; hearing the slide of fabric against skin, I imagined her lowering her panties. Though the growing silence between us felt a little awkward, I couldn't think of anything to say.

Finally, she slipped under the covers. The bedsprings squeaked ever so slightly as she lay down. "You can look now," she said softly. 

When I turned in the chair, I found she'd pulled the covers up to her chin. My stare darted to the floor, where her pink panties had been discarded. "Comfortable?" I managed to ask in a raspy voice.

Wren nodded. "I like your bed. It's bigger than mine."

"Plenty of room for you to spread out," I said, then flushed with embarrassment. I hadn't meant anything by the remark, but it sounded dirty to my own ears.

She only giggled, her eyes full of excitement. "Here goes nothing!" Fumbling beneath the covers, she turned on the vibrator. 

Mere seconds passed before my friend released a pleasured moan. I could see the outline of her legs, which were indeed spread wide. My dick jumped in response. The sight of Wren in my bed, with her hair fanned out across my pillow, was hot enough on its own. But knowing she had that vibrator between her thighs, and against her clit, made me desperate to jerk off. 

I waited until her eyelids fluttered closed, then furtively gave my erection a stroke. That fleeting touch did nothing to alleviate my horniness. If anything, it made it worse. 

"It's definitely powerful!" Wren said, her voice low and guttural. "Mmm, I'm keeping it right on my clit."

An involuntary groan escaped me. Wren must have heard it, for her eyes locked with mine. Her lips were parted, and I could make out the sound of her heavier breathing over the toy's insistent buzz. Her stare traveled from my face to my chest and belly, then settled on my crotch. 

Shifting in the chair, I tried to hide my hard-on while apologizing. "I can go if you want."

"I want you to stay," Wren said through another moan. "It's okay if you're turned on, Logan. I mean, I'm playing with my pussy in your bed."

I pressed a hand to my forehead, struggling to control my arousal. I could only pray that my precum didn't soak through my shorts and leave a visible wet spot. 

"Do you think I'm pretty?" Wren asked.

"I think you're beautiful."

She beamed at my words. My gaze remained riveted to her as she started writhing. "I'm gonna come soon! My pussy is dripping wet, and I don't think my clit has ever been so sensitive!"

Leaning forward, I licked my lips. "Please," I begged. "I want to see you come, Wren!" By this point, I was almost panting.

She rocked her hips, causing the bedsprings to issue rhythmic squeaks. In the process, the covers slipped down her body, and I gasped to find she'd lowered the bodice of her sleeveless dress. At some point, she'd lifted her tits from the cups of her bra, and her rosy nipples were hard, as if begging to be sucked. 

Without thinking, I placed a hand between my thighs. Desperately, I stroked myself through my shorts while Wren got closer to orgasm. Her breasts weren't large; in fact, I'd be able to cradle them in my hands. But my God, they were so sexy!  

Her wails intensified, reverberating throughout the room. She sounded like a woman being fucked senseless. Giving me a seductive smile, she managed to say, "I love knowing you're so hard!"

Fuck, I was afraid I'd come at any moment! By some miracle, Wren got there first. When the orgasm descended upon her, she arched her spine and quaked. It was as if a fierce current surged through her entire body. I'd never seen anything like it! Her cries strengthened to screams, and she thrashed in my bed. Those spasms went on for at least twenty seconds, subsiding only after she turned off the vibrator.

"My clit needs a break!" she said, still breathing fast.

I needed a break, too. I needed to retreat to the bathroom and jerk off, because I was so hard it hurt. Yet I stayed where I was, afraid something priceless would be lost the second I moved. 

Wren's smile turned sly as she regarded me. "Come over here, Logan." 

I knew my face was pathetically hopeful. "Why?" I croaked out.

She pressed her tits together, as if I required more persuading. "Because you need to come, and I want to see you do it."
