Ms. Welker identifies other aspects of female arousal.

"Mmnugh!" I shudder, collapsing onto the teacher's desk, vaguely aware of a cup full of pencils and pens spilling nodding onto the floor. I'm even less conscious of my friends and classmates crowding around me, my attention entirely occupied by Jason's cock (oh my God...) sliding gently in and out of me.

"Oh, excellent, very responsive, Emily! You're an ideal example of feminine sexual response!" Ms. Welker leans over naked body, splayed across her desk, and runs a finger around my nipple.

"Ungh!" I cry out as her touch sends little electric shivers up my spine.

"See here, class, her areola is experiencing hightened sensitivity as an erogenous zone during intercourse." Her finger continues to tease at my nipple, and I can only shiver in reply. "Here, everyone give this a try!"

Suddenly hands grope me from all angles, squeezing, teasing, pinching, pulling at my breasts. Someone's hands slide down my stomach, massaging gently at my clit.

"Oh fuck!" My body tenses, Jason's cock sliding in and out of my pussy, my classmates' hands groping my naked body, someone teasing my clit. It's all too much all at once.

"Oh, well done, Sarah!" Ms. Welker says to the girl rubbing at the tip of my slit, Jason's cock inches from her hand. "That's another key area for sexual excitement in girls!"

"I know..." Sarah replies.

"Oh God... Oh my God..." My hips are writhing, my face is tightening, my whole body is starting to tingle.

"Excellent, well done Emily!" Ms. Welker says. "Class, you are about to see a genuine orgasm!"
