They're not caught (yet)

Marinette may not have experience in giving blowjobs, but she more than makes up for that with her enthusiasm. Her head bobbing on Adrien's cock as she holds on to him for support. She hopes she is doing a good job and when she looks up at him with her puppy dog eyes, something snaps inside Adrien and he loses any remaining regret or inhibition he had of fucking his cute classmate. Adrien grabs Marinette by her head and before she can protest, he begins to facefuck her.

Any attempt to stay quiet is abandoned and the hall is filled with loud slurping and gagging noises. Marinette had dreamed of her first time with Adrien being romantic, slow and most importantly private affair. Now she is getting used by him. Still, she is getting used by Adrien Agreste, and this is turning her on more than she was willing to admit. It doesn't take long for Adrien to blow his load down her throat and by then Marinette is barely conscious from how horny she is. She tries to swallow it all but as Adrien clamps her head against his groin she gags and is **** to pull out, leaving Adrien to spray some of his cum on her face and hair while she is left gasping for breath.

"Did... *gasp* Did I... Do good?" Marinette finally manages to ask and give an awkward smile. She may be half-naked, covered in cum and kneeling on the school floor with no foreseaable way to get out of this disaster of a situation, but at the very least she had to try to give a good impression to Adrien.

Adrien for his part is pulling his pants up again and hiding that delicious cock, but he does nod. He seems to be thinking of something and Marinette hopes that he has thought of some way to salvage this disasster.
