I often went without underwear, especially since I'd started my arrangement with Noah. I didn't want any potential barriers between us and, to be honest, my dick rubbing against my denim jeans made me tingle with anticipation.
Somehow, being bare was less intrusive than the green G-string I was wearing. It cut through my ass cheeks and with each step I had to remind myself I didn't have a wedgie, this was just what women put themselves through each day. The silk front was too small for my dick and I resisted the urge to re-adjust. I'd already done that a million times this morning, after I opened the box Noah left on my bedside table.
A present.
We'd had sex last night, and my muscles ached with the delicious memory. Noah was less tentative this time, more demanding, if that was possible. I'd been face down, ass up five minutes after he walked into my bedroom. Noah swiped his hand through my assignment notes, and they fluttered to the ground as he tugged my shorts off.
Fervent. Primal.
He rode the edge of rough and it unlocked something that had never happened to me before. A hand-free orgasm. My release had covered my bedspread. The orgasm shuddered through me as Noah's hips slapped against my ass and his grunts filled the air.
Instead of being grossed out, he carded a hand through his sweaty locks and slapped my ass.
"You just can't help yourself, can you baby?" He'd whistled and jerked up his pants, that had been around his ankles.
The next day he'd left me a white box on my bedside table, with a black ribbon and a note that read. 'Wear these for me.'
I opened the box to find seven silk G-strings, all in different colors. My eyes just about fell out, but I did as Noah asked. They weren't the right size, clearly made for a petite woman, not me. I'd never worn lingerie before, and the slide of silk against my intimate parts was exhilarating. That no-one knew I was wearing sexy underwear, given to me by my straight roommate, was even better. My dick kept hardening at the most inappropriate moments. Like right now, walking with Zane after class. He nudged me with his elbow.
"Earth to Bran. What are you thinking about?"
A car sped past us, the occupants hollering out the window at someone up ahead. Zane moved closer and his arm brushed against mine again. He had shoulder length black hair he normally tied back in a ponytail but had left loose today. The long hair, baggy pants and band tees made him look like a rockstar, and he had a sultry way of staring at me from underneath his thick, dark lashes.
"Just this assignment. I think one more session should be enough to polish it up, right? I need to check those references." The string between my ass cheeks was impossible to ignore. It rubbed against my hole with each steady step. Zane dawdled to a stop and checked the calendar on his phone. Tucking his smoothie into his arm.
"I'm free Friday night? Did you wanna come over to mine for pizza or something? We can work as late as we need to. Maybe watch a movie afterwards if we're not too brain dead."
His hopeful smile made my stomach spark with warning. I didn't think Zane was into guys, but we'd never really talked about it. Finishing up the assignment and following it up with pizza and a movie would have been the perfect night for me. Except all I could think about was Noah. He had an exam that day and I wanted to be available. My mouth watered, and the silk wrapped around my hardening dick like a vise.
I couldn't say no to my roommate's cock or the way he bent me over. His hard rod slamming inside me, hitting that perfect spot each time. The way Noah called me baby. It was still wild to me he'd rearranged my guts, and we hadn't even kissed.
"I can't," I grimaced, adjusting my strap over my shoulder. "I'm doing something with Noah."
"Your roommate?" Disappointment threaded through Zane's voice.
"He's finishing up exams and we're going to celebrate."
With him riding my ass, hopefully all night.
Zane's face brightened. "Well, what about Saturday? I think Sandy is throwing a party. Isn't she Noah's girlfriend? Speaking of---" Zane waved his hand, and I froze as I followed his eyeline. "Hey Sandy, come here for a sec."
"Ex-girlfriend." I muttered under my breath, my lungs burning from a sharp exhale. Sandy flounced over, wearing a pleated, baby blue skirt that hit mid-thigh and a tiny white crop top that showed off her ample cleavage. Nestled between the soft swell was a heart-shaped gold necklace, and it glinted in the sun.
"Hey handsome, it's been too long." Sandy squealed, wrapped her arms around Zane's neck and smacked his cheek with a loud kiss. Her gaze narrowed when she noticed me, and she took a step back. The warmth she'd shown Zane trickled away.
"Are you having that party on Saturday? I'm gonna bring Bran." Zane bumped into me with his hip, biting his lower lip. Those thick, gorgeous lashes brushed his cheeks, almost like he was...flirting with me? Sandy snatched the smoothie Zane was holding and took a sip.
"Sure am. I'll see you there, but can I talk to you in private for a sec?" Sandy looked at me as she passed Zane his smoothie and reached out to pluck at my sleeve. Zane shook his head, as if used to her antics. He reached out and squeezed my elbow. Tingles shot down my spine and I masked my surprise with a cough. Not in a good way. I wasn't his to touch. Technically, I wasn't Noah's either, but I didn't want to focus on that.
"I'll text you later." He promised, and I waved as he wandered down the street. Zane was a nice guy, but he did nothing for me physically. I knew objectively he was handsome, and from this interaction, interested. But my mind was full of Noah and my body craved only him. My chest ached at the thought of him being done with me, but with Sandy standing in front of me, I knew it was only a matter of time. Noah was straight and Sandy was a gorgeous woman.
"What's up?" I asked Sandy awkwardly.
"I think you know why I want to talk to you, Brian." Sandy chewed on her plump lower lip.
"It's Bran."
"Sorry. We've never really talked before, have we?" Sandy let out a soft laugh. "I mean, can you blame me? You live with Noah, so you know what he's like."
My throat dried, and I was more aware than ever of the G-string I was wearing. My body prickled all over with heat as silence dragged out between us.
"What do you mean?" I forced the squeaky words out past the knot in my throat. Did she know something happened between Noah and me? He wouldn't tell anyone, would he? Sandy glanced at the road, watching cars roll by with a faraway look. A truck belched a cloud of black smoke, and it seared my nostrils, even from the sidewalk.
