The text from last night still burned in my pocket when I climbed the stairs the next afternoon. We shouldn’t have done that ... but I’m glad we did. Office hours tomorrow? My hands shook the whole way. The storm had cleared, leaving the campus wet and shining, but my blood was still roaring. Rebecca—plain Rebecca now, no title—had almost kissed me. Her foot on my calf. Her breath tasting like wine. I told myself I was just going for more paper help. But my cock knew the truth.
Her door was closed this time. I knocked once, soft.
It opened immediately.
She stood there in a crisp white blouse and charcoal skirt, but everything felt different. The blouse was tucked tight, buttons fighting her 36DD chest. The skirt hugged her wide hips and stopped just above the knee. When she stepped back to let me in, she crossed her legs at the ankle and I saw it—lacy black tops of thigh-high stockings peeking out, the delicate trim biting into soft pale flesh. My mouth went dry. The wedding ring still glinted on her left hand as she turned the lock with a quiet click.
“Lock the door, Alex,” she said, voice low and steady. “Just in case.”
The sound of the bolt sliding home hit me like a shot of adrenaline straight to the dick. The small book-lined office felt suddenly smaller. Old books, vanilla perfume, the framed family photo on the desk watching us. Her two teenagers smiling, her husband looking away. Guilt twisted hard in my gut. This was wrong. So fucking wrong. But my cock was already thickening against my jeans.
She didn’t sit behind the desk. She took my hand and pulled me straight to the little couch from last night. The same gray sweater dress was folded neatly over her chair now—yesterday’s storm clothes. Today she was all business on the outside, pure sin underneath. Her hazel eyes locked on mine behind the black-rimmed glasses.
“I couldn’t sleep,” she whispered. “Kept thinking about how close we came.”
Then she kissed me.
It wasn’t soft. It was hungry. Her full pink lips crashed into mine, tongue sliding in like she’d been starving for months. I tasted the faint cherry of her lip gloss and something deeper—want. Her hands fisted my shirt, pulling me on top of her as she sank back onto the couch. The blouse strained as her heavy breasts pressed against my chest. I felt the lace of her bra through the fabric, the soft give of her belly, the heat between her thighs as her skirt rode up and those stockings whispered against my jeans.
“Rebecca...” I groaned into her mouth.
She bit my lower lip. “Not yet. Just feel me.”
I unbuttoned her blouse with shaking fingers. One button, two, three. White lace bra finally exposed, her pale freckled cleavage spilling over the cups. She reached back and popped the clasp herself, letting the bra fall away. Her breasts tumbled free—full, soft, heavy, nipples already tight and dark pink. I lowered my head and sucked one into my mouth, tongue circling, teeth grazing just enough. She arched, a soft moan vibrating against my lips.
“Oh god, yes ... like that.”
Her hands tangled in my hair, guiding me from one breast to the other while her hips rolled up against my thigh. The skirt was hiked to her waist now. Black lace panties soaked through, the tops of those thigh-highs framing everything like a gift. I could smell how wet she was—musky, sweet, desperate. My cock throbbed so hard it hurt.
She pushed me back gently, cheeks flushed, glasses slightly crooked. “Stand up.”
