katy manages to finish the chapter and the summary before she gasps as she cums hard and sits back down on the chair panting, the chair is now sopping wet with her juice, and a few of the boys are taking pictures for future blackmail on the hot red head while muttering things like "she actualy had an orgasm in the middle of class"

A grin spreads across his face slowly, than an obviously feigned look of concern is plastered onto it. "Are you alright miss? "

katy manages to nod slightly

The substitute smiles widely, and a second shadow slithers up her leg. "Good. You, start the next." he gestured to another student, as the second shadow moved inwards.

the second student begins reading as katy jerks a bit as she feel the second shadow slithering up her leg

The demon grins even wider, "Good, now summarize." the second shadow slithers in towards her ass, flickering over it gently at first.

"oh god no...." katy moans quietly as the student continues to read

He tilts his head slightly, as if over hearing someting, and the shadow thickens, bending like no natural substance can, before a cylinder about an inch wide is pressing tightly against her puckered hole, on the verge of penetration. "Good. I think one or two more, and We'll be finished. You, begin." He pointed to the student directly behind Katy.

the student stands up as katy gasps, causing the student to snigger as he begins to read

The sub raises an eyebrow, a slight frown on his lips. "Is something funny, sir?" The second shadow pushes in, a full four inches at once, forcing her open.

katy gasps in pain

"no sir" the boy says continueing to read the chapter

He grins, pushing the shadow deeper, licking his lips, as the original shadow suddenly picks up speed, to a very frenzied pace, a small tail sliding out to attack her swollen clit.

katy gasps loudly and shackes in her chair

the boy stops, then continues

The teacher frowns, locking his eyes onto the redhead. "You've disturbed the class too many times miss. Stay after, so we can talk about your behavior." Pointing at the student right in front of Katy, he says, "You, turn around to the class, and summarize for the stuttering child, than read the last chapter."

katy groans as she tries to control herself as the student infront of her summerizes the chapter
