Siobhan wraps her tongue around my cock and slides it up to the base of my erection, then she drags it down to the head.
"Fuck, Siobhan," I growl. "Are you trying to give me a heart attack?"
Instead of answering my question, she moans deeply and shuts her eyes. Her mouth glides up and down my skin, and she starts sucking gently.
Christ, if I'd had any blood left in my brain, it's all flooded south now.
A phone rings. I have no idea if it's a mobile or a landline, and I can't think at all, so no chance I'll figure out the answer. I'm breathing so fast my ears have started to ring. Maybe that's what I'm hearing? No, it can't be—
Siobhan massages my balls and sucks harder.
I gasp, grip the chair's arms so tightly it makes my knuckles ache, and grit my teeth. The best kind of pressure bears down on my entire body, settling in my cock.
That phone stops ringing.
Choking back a shout, I push up on the chair's arms without meaning to, and my arse lifts off the seat a little. I feel the climax coming like a runaway train, the need getting stronger and stronger because she sucks harder and pumps faster while making the most erotic grunting noises I've ever heard. My entire body freezes, my lungs too. Shocks fire down my spine straight into my cock, and I couldn't stop this if I wanted to.
I come inside her mouth while she keeps going, and a strangled shout erupts out of me.
Only once I'm done, and she's wiping her mouth with a tissue, do I realize someone might have heard the noise I made. Can't do anything about that now. I'm still struggling to breathe normally, and my heart is still racing like a deranged greyhound. I slump in the chair.
Siobhan tucks my dick back into my trousers and zips me up. She sits there watching while I gradually regain the ability to breathe without gasping and to sit up straight instead of slouching so far down that I might ooze off the chair.
"Christ, Siobhan," I say when I become capable of speech again. "That was incredible. You're bloody brilliant at giving head."
"Never done that before. I looked up instructions online and downloaded an ebook that had even more information."
"You—what?" I gape at her, and I don't feel embarrassed about doing that. "You researched how to give a blow job? And you're serious about never having tried to do this before?"
She nods, biting her lip.
I laugh, though I'm still somewhat breathless. "If you can learn overnight how to give bloody incredible blow jobs, I can't wait to see what happens the next time we have sex."
"You liked it, then?" She seems genuinely surprised by that fact.
Leaning forward, I cradle her face in my hands. "No, Siobhan, I didn't like it. I loved it."
She turns her face into my palm to kiss it. "Time to get back to work. For me, anyway."
"But I haven't repaid the favor you just did for me."
"Later." She stands up and clears her throat. "I'll meet you at your place tonight, eight o'clock."
Someone steps into the doorway behind her.
The man glances from Siobhan to me and back again. "Everything okay in here?"
He's British, like me. Maybe this is the friend she mentioned on the day we met.
My clandestine lover whirls around to face the other bloke. "Sanjay? What are you doing here?"
"A student heard a strange noise coming from in here and told me about it. She thought you might need help."
"No, we're fine. Just talking shop." She gestures toward me. "Sanjay, meet my newest student, Nick Hunter. He's British too. Nick, this is Sanjay Desai, my friend and colleague."
I heave myself out of the chair because jumping up is out of the question right now and approach her colleague, offering him my hand. "Pleasure to meet you."
"Always nice to meet a new student," he says, shaking my hand. "You're not a typical college student, though, are you?"
