Dave zoned out of whatever the professor was talking about ages ago, his mind shutting out on utter boredom. It's a gloomy rainy day and he can't help but let it affect his spirits. He gets his phone, flickering through the apps in search of a distraction, but coming out short. There's really nothing he would like to do, except maybe to go home and sleep. He can't, however, since presence is mandatory and he's already almost exceeded his limit of absences.

He opens the last message Sebastian's sent him, a simple Night Dave that had been prompted by Dave's own good night message. Smirking, he glances at the professor, who's still lecturing about some work of art that has absolutely zero to do with the content of the class as far as Dave can see. His classmates are divided. A small portion is actually paying attention and even taking notes, while a few brave ones blatantly sleep and the majority of the class, like him, is doing something else. He quickly types in a new message for his boyfriend, hands under the desk.

Thinking of you.

It's simple and innocent enough, but a good way to start a conversation if Seb is available. If he isn't, it doesn't say much either. He soon gets a reply, though.

Dirty thoughts, I hope.

He grins, biting his lower lip.

No other kind when you're involved.

He sends it and waits, eyes flickering to the teacher just in case he's looking back at Dave (he isn't; he never is). The phone buzzes in his hand and he grins again when he sees the message.

Jerking off?

Unfortunately, no. Class. L You?

I am now. ;)

He double checks to make sure he's got it right, but there's no mistaking in the undertone. He decides to go for a good humored text, just in case. He's never exchanged sex messages with Sebastian before (or with anyone, for that matter), and he's pretty sure being in the middle of class is not a good moment to start.

Not in class then, I hope.

He holds his breath while waiting, looking around to check if anyone's been looking at him, but they always seemed preoccupied with their own phones. He wonders if any of them is sex texting…

Home. In bed. Naked. Cock in hand. Get the picture? ;)

Dave swallows thickly, heart hammering in his chest. He does, he most certainly does get the picture. He adjusts himself, cock starting to strain against his jeans and looks around again, then just shrugs. It's not like he really cares, either way.

You tease. You stroking yourself? You know you're driving me crazy. Wish it was me.

What would you do?

That's his cue. He licks his lips, closing his eyes for a second and seeing Sebastian's perfect naked form before him.

Run my hands down your chest. Pinch your nipples. Kiss your neck.

He forces himself to take deep, calming breathes, trying to control his erection enough not to come in his pants. His phone buzzes in his hand.

Fuck yes. Your hands are sexy. Wanna suck your fingers 1 by 1.

I'd fuck you with those fingers. First one, then another, then all of them. In and out, slowly, then faster and faster, brushing against your sweet spot.

He hits send, wondering briefly if "sweet spot" sounds too corny and suddenly wishing he wasn't so inexperienced in this, in everything. The reply comes quickly, though, and he relax.

Doing that. Imagining you.

The mental image of Sebastian finger fucking himself takes him by assault and he sits back, putting the phone back on the desk and taking a deep breath, counting to ten. The phone buzzes again and he picks it up.

Feels so good Dave. Better if it was your fingers. Or your cock. Maybe both.

He bites his lips to repress a groan. He glances at the time on the phone. Only a few more minutes until class is over. Thank god.

Can't wait to be inside you. To grab or hips and slam my body against yours. Wanna feel you around me.

Me too. Come soon. I want you. Gonna kiss your lips and bite your shoulder and grab your ass while you fuck me.

I'll be there soon. Are you ready for me?

It takes a full minute before the screen lights up again.

Yes. Waiting. Hurry.

The professor dismisses the class and it couldn't come a minute too soon. Dave sprints out as fast as his condition allows him, books strategically placed as he joins the crowd leaving the class. He races through campus, the thought of what expects him making him even hornier. He's never been more grateful that both he and Sebastian go to the same university.
