Walk over to her

"Can I join you?" I whisper in her ear, "don't move"

She blushes and nods nervously, staying still as everyone continues to paint her.

I walk up to her and kneel down in front of her, grabbing her soft thighs and spreading her legs wide apart. I place my face in between her legs and lean forward to lick her pussy from clit to hole, tasting her sweet juices. Her moans fill the room and I pull my head back to look at her, watching as her whole body shakes uncontrollably.

Seeing that she has finished painting, the shocked teacher turns to look at her curiously, "what are you doing? are you okay?"

Kate is breathing heavily and looks away from the teacher, "I...I cant...its too much...I need to cum..."

The teacher looks concerned and kneels down beside her, "Kate! What's wrong?!"

Kate looks at the teacher and then down at her pussy, "I... I just cant stop myself... I love having my pussy eaten... its so good... mnhmmhmmm" she cries out as she feels my tongue on her clit, moaning loudly. The teacher and all of the other girls stare in disbelief as they witness what appears to be a girl climaxing uncontrollably.

As Kate calms down she recomposes herself and looks up at her teacher and classmates, "I'm fine... I'm sorry, I just... I couldn't control myself..."

Her teacher looks at her with concern, "You really shouldn't play with yourself during class Kate, its unprofessional"

"Oh... but I didn't" Kate says, "It wasn't me, it's him! he came into our class and started licking my pussy! He's such a bad boy... he was taking his time making me cum so many timess...! "

"Kate...? Theres no one else here aside us and you?" says her classmates, all of them looking at Kate with shock and surprise.

"Wait what?? No HIM!" Kate shouts point at me, "Can't you see him?!?"
