Day Dream shivered in her professor’s gentle hands, then let out a husky moan as she felt Study’s finger slide down her stomach toward marehood. Her back arched, her wings stretched and the familiar heat filled her. Such a wonderful heat… she knew she should control it… but she just… just couldn’t.

“I’m… I’m sorry…” Day Dream whimpered. “I’m not… I don’t want to be naughty… even if…” The finger slipped past Day’s skirt as Study’s hands lifted her top. “I can’t… I can’t stop…”

“Sssh…” Study Break murmured as the finger neared Day’s aching marehood. “It’s natural for one of you western pegasi. You’ve just got it a lot stronger than most! But, let’s see if we can work some of it out of your system before you go see Lily, hm?”

Day Dream nodded. Even with the pounding lust of Long Heat pounding through her head—and her sex—she smiled. Study Break had always been so understanding of her aching needs. The Long Heat had hit her so hard to the point where her grades were starting to suffer. Study had even been willing to tutor her… after making sure she could focus properly. And everypony knew there was only one way to get a western pegasus filly to focus in the Long Heat…

Day gasped as she felt the finger enter her intimate place like it had so many times before. Study Break had learned every trick of Day’s body since Day had moved here.

Within the first week, Study had learned one very important thing about Day. Something Day hadn’t even known herself before the Long Heat had swept over her.

“You’ve been naughty… but I know you’re really a good filly, aren’t you?”

“Oh yes, Miss Study,” Day gasped as the finger went deeper. “I’m a… haaaaaahhh… good filly.”

“What kind of good filly?” Study murmured as her other hand caressed Day’s aching left breast.

“A good… a good…” Day whimpered. She knew what she needed to say. She bucked around Study’s wonderful, understanding finger as she tried to get out the coherent words. “A good… submissive filly.”

“Yes…” Study moaned. “Oh Day… you’re such a good filly.”

Study’s finger shifted just a little to the right and Day let out a cry as the fifth female orgasm of the day washed over her body. Her wings flared to her full length, completely beyond her control. Her legs buckled and it was only Study’s strength that kept her from falling to her knees.

“Profess… Professor…” Day moaned the word, her mind filled with wonderful glorious heat. “You… you… you’re so… good to me…”

“Mmmm,” Study hummed. “It’s the least I can do for such a good filly.”

Even though Study’s finger hadn’t shifted a bit, the words sent another bolt of ecstatic pleasure through her. She yelped as she tried to milk the professor’s finger like a cock.

Mmm… it feels like forever since I’ve had an actual dick in me… Day thought as she mentally wandered through red hot clouds.

“Grab the chair in front of you, sweetie,” Study cooed in her ear. “Hold yourself up. One more lesson for today.”

Day giggled a little. Her lessons with the wonderful Professor Break were always so satisfying. She happily did what she was told, even as her body continued to tremble.

Study shifted around her and Day let out a whimper of desperate need when the professor pulled her glorious finger out of Day’s soaked sex. She reacted purely on instinct and lifted her tail, completely unable to retract her wings.

“Now, time for a quick pop quiz,” Study said from somewhere behind her. Day tried to turn to look, but Study reached out and squeezed her ass. Day let out a groan of pleasure and obeyed, staring straight ahead. That particular signal had taken only three days to sink in. Now, she could no more resist that signal than she could go two days without fucking somepony.

Oh… and when Red found out about that little trigger… Day giggled dreamily to herself, remembering how wonderfully exposed she had felt that day.

Study slowly shifted her supple, shapely body and pressed it against Day’s back. Study’s fingers gently traced Day’s wings, sending more pleasure than she could cope with through her body. Day gasped out her professor’s name again.

“Mmm… yes…” Study murmured, once again whispering in her ear. The hot breath seemed to go straight through Day and right down into her aching sex. She bucked her hips against the older mare, silently begging for her touch.

“Now, my goodfilly,” she paused as Day’s body shuddered again. “I’m going to ask you to do something. If you do it, I give you an orgasm so hard, those wonderful tits will fill right to the brim.”

Day froze even as her entire body went red in excitement.

“I… I didn’t think…” Day murmured. “I didn’t think I could… yet…”

“You’re almost ready,” Study whispered encouragingly. “And even better, I promise your gorgeous little friend Lily will drink every drop of it from you.”

Day almost came right there at the thought of the gorgeous orange-maned filly suckling her milk-filled titties.

“So… do you want to feed Lily this afternoon?” Study Break asked, her breath hot and wet against Day’s twitching ear. “Hm? Having her lap away…”

Day shivered again.

“Well… does that sound like fun?”

“Yes please…”
