You start to write the exam

You start reading the first question and find that you... can't stop. It feels really nice. You read the question all the way through, a warmth growing inside of you, until you've fully read and understood it. You shiver as a tiny wave of arousal hits you. What's even better is that you realize the answer, and start to write it down.

As you write your answer to the question, the ever-present warmth builds again, surging whenever you come up with a clever thought or answer. It's not long before the first answer is written out and you're happy with it. You realize that the implant is definitely working as intended, as your pussy grows warmer. Re-reading your answer, you realize that it's pretty good! Better than it might have been otherwise, actually. You smile discreetly. With the implant... encouraging you to do well, you'll definitely get a good grade, and... oh... getting a good grade would be nice. Your breath catches as you picture an A at the top of the paper, or even an A+. Picturing the TA reviewing your answers line by line, putting comments and giving you good marks...

You realize that your thighs are pressing together involuntarily and that you're unconsciously sucking on the end of your pencil. You take your pencil out of your mouth and greedily turn to the next question.
