With My Friend’s Mom at the School Library
A few days after I fucked Auntie Saea in a public restroom, Sunday morning rolled around. Midterms had only just finished, leaving the central library’s reading room nearly empty. I sat in a corner seat, halfheartedly paging through my major textbooks.
Haah… This is boring. Not that I can go out anywhere with Lisa around. Seoa’s off campus too—her department play is coming up soon…
Seoa was in the theater department, and with the performance only a month away, she was going to be busy every weekend for a while. I flipped pages without really reading them until a good idea suddenly struck me.
Lisa has a lunch appointment and can’t eat with me anyway… and if Seoa’s not here, I can just call Auntie Saea to campus, right?
The mere thought of her sent a surge of energy through my body. At the same time, all sorts of ways to play with her started spinning through my head.
In truth, if Auntie simply insisted she’d worn Seoa’s clothes, I had no real way to tell. I just spoke as if I could.
Ha. Still three hours left… Might as well study.
I managed to focus on my books after that, until I felt someone settle into the seat beside me. I glanced over and found Auntie Saea sitting there with a slightly prim expression. She had a blue baseball cap pulled low over her face and was wearing a burgundy sweater Seoa often wore, paired with black wide-banding jeans.
Is it because her chest is a cup bigger than Seoa’s? The fit looks different.
Even in the same sweater, Auntie Saea’s chest strained the fabric far more tightly. It was a campus look she never normally wore. On top of that, she’d copied one of Seoa’s favorite outfits down to the set, clearly trying not to give me anything to nitpick. The ball cap hid more than half her face so I couldn’t see her eyes clearly, but I could feel her glaring at me all the same. I leaned in and whispered.
“What did you tell Seoa when you put those on?”
“…Seoa doesn’t know. I parked on campus and changed in the car.”
Ah. That works too.
“Alright. Time for the punishment inspection, don’t you think? Pull your pants down a little.”
At my words Auntie flinched and twisted around, scanning the room.
“H-here?”
Midterms were over, so the fourth-floor reading room of the central library was practically deserted. The few people present sat far away; no one was near us. Still, the outer wall behind my seat was floor-to-ceiling glass, so her hesitation made sense. Of course the glass was treated so no one outside could see in, but from the way she reacted she clearly didn’t know that.
Then again, how many people carefully check whether you can see into a library from outside? Most just think, Wow, the central library’s exterior is all glass, and leave it at that. I could have told her the truth, but keeping it secret was more fun.
“Cha Saea. Are you going to disobey?”
“W-what if people outside can see everything?”
“You’re wearing a cap pulled low, and we’re on the fourth floor. They won’t see much from outside.”
“If you keep dithering, someone might come over this way.”
Auntie hesitated a long while before undoing the button of her pants, lowering the zipper, and sliding them down to her thighs. Her pure white crotch gleamed almost dazzlingly under the bright reading-room lights. Neatly trimmed black hair fluttered softly above her pale pussy, teasing me. Between the tightly closed slit of her folds, a black ring was just visible.
Whoa. She deliberately left just the ring peeking out so it would show from the outside?
As always, Auntie Saea’s obedience was flawless. When she saw where my eyes were glued and hurriedly tried to pull her pants back up, I caught her hand and stopped her, then held out my other palm.
“Hand it over. Now.”
“W-what?”
“Are you going to keep playing dumb? If you put a vibrator in, there’s a remote, isn’t there?”
“I… I can’t.”
“Ah-ah!”
For a second her reaction made me wonder if she hadn’t brought the remote after all, but a pervert like Auntie would never do that. She must have anticipated exactly this the moment I ordered her to insert the vibrator. With a look of resignation she lowered her gaze, carefully took a pink remote from her bag, and laid it on my palm. The instant I had it I set the vibrator nestled inside her pussy to medium power.
Bzzzzz.
“Hngk!!?”
Auntie clamped both hands hard over her mouth, stifling the moan that tried to escape, glanced frantically around, then glared at me. Her eyes were full of resentment. Of course I ignored that look completely and said only what I needed to. I was the master; she was the slave.
“Did you bring a book to read?”
“N-no. Hngk!?”
“Then go down to the third-floor stacks right now and check out whatever you feel like reading. I still have studying to finish. Seeing you got into the library just fine, I take it you borrowed Seoa’s student ID?”
“Hnggh!!? Uh… uhh… please, the vibration… hngiiit!!?”
Even at medium power she couldn’t keep her wits about her; she tried to answer in a whisper only to keep leaking moans.
“Fine, fine. If you go get a book in that state, I’ll turn it down.”
“Okay. Okay, so… hngk! Please just… hiiit!!?”
Only after I dropped the vibrator to its lowest setting did her moans finally stop. Her face was still flushed a deep pink, though.
“Th-then I’ll be right back. You absolutely mustn’t turn it up, okay?”
The pleading look in Auntie Saea’s eyes was so cute I smiled and nodded. Once she left the reading room I moved to a seat that still had a clear view of the entrance but was as out of the way as possible—most of the room was empty anyway—and waited for her.
A good while later, the moment I spotted her coming back through the entrance I cranked the vibrator to maximum.
“Hnggegegeeeeet!!?”
Auntie let out a bizarre scream and crumpled to the floor. The reaction was so violent it startled even me; I hurriedly dialed it back down. A couple of people sitting nearby stood and hurried over to where she had collapsed by the door. My surprise lasted only a second—then the situation became extremely interesting.
This could be fun too.
We were far enough apart that I couldn’t hear the conversation. I only saw Auntie bow her head in thanks to the people who’d helped her up, and one of them say something to her. She shook her head, bowed once more, then started walking toward our original seats. I quietly followed close behind, tempted for a moment to give her firm ass a light squeeze, then held back.
If she screams, we’re done. Better not.
Instead I gave her back a couple of light taps. She turned with a puzzled look, recognized me, and instantly fixed me with a glare so full of resentment it almost felt cold.
“Y-you… how could you…! I told you not to!”
Despite the fierce expression, she whispered so softly only I could hear. Without a word I took her hand and led her back to our seats.
“Auntie. What did you talk about at the entrance?”
“Shouldn’t you start with an apology? What if we’d been caught?”
“Hmm… Our Saea still can’t get her head straight enough to answer properly, can she?”
The moment I switched to that coercive, casual speech, Auntie gave a little shudder and lowered her head. From the past few days with her I’d learned that when I used casual speech she really seemed to feel like she was the inferior one; her reactions were completely different from when I spoke formally.
That gap is the delicious part.
“…Th-they asked if I was okay, and one of them… asked for my number…”
Whoa. He thought about asking for her number in that short time? That bastard’s a lunatic too.
“And?”
“I turned him down, of course.”
I reached over and groped her breast through her clothes, kneading it. Auntie lifted a hand as if to resist, then checked that no one was nearby and let it drop again.
“Good girl. Your body belongs to me for a month—no other guy gets to touch it. You know that too, right?”
“Th-that’s right.”
My touch must have excited her; not only were her cheeks flushed, even her earlobes had turned red-hot.
“Now pull your pants down to your thighs like before and read the book you brought.”
“Huh? Huh…? Do I really have to?”
“Ask one more time and I’ll strip you completely bare.”
Auntie gave a slow nod, undid her button and zipper again, slid her pants to her thighs, and parted her legs a little.
Ha. She already knows exactly what I’m about to do.
I slipped my hand between her spread thighs and rubbed the pale surface of her pussy and her lower belly while I finished the day’s studying. Thanks to the soft, springy feel of her skin, I somehow concentrated better than usual. When I packed the books on the desk into my bag, I checked what she’d checked out. Sitting on the desk was a volume titled Pride.
“Why’d you pick this one?”
“It’s… a book I like.”
Schlick-schlick ♡
“Hnnngh!!”
Even though the vibrator was still on its lowest setting, the moment I eased a finger into her pussy Auntie clamped both hands over her mouth and moaned.
“What do you like about it? The male lead?”
She nodded slightly, face already crimson, still fighting the sounds.
“Wow… for real? You’re confessing right in front of your master that you like another man? A mere slave?”
I immediately used my index and middle fingers to stir inside her. The tip of my finger caught on the pink egg-shaped vibrator.
“Hngk!!? N-no… st-stop it ♡ Hnnnngh!!?”
Love juices spilled from her folds and soaked my fingers.
“Have you apologized or not?”
“Hngyaat!!? I-I’m sorry!! Please… st-stop!”
Auntie’s eyes flew wide; she clamped her hands over her mouth as hard as she could and shook her head frantically at me.
“Why? Your mouth says one thing, but your body’s so into it you’re burning up red.”
Auntie Saea shook her head left and right in rapid, desperate little jerks. That pitiful look made me want to keep going, but getting caught would land me in trouble too, so I pulled my fingers free.
“Hah… hah… Please, if you’re going to do it, do it somewhere else.”
“What exactly do you want to do with me, Seoa’s mother?”
Even when I dragged Seoa’s name into it she didn’t snap the way she usually did. Escaping the present situation was clearly her top priority; she showed no irritation and just kept talking.
“I… I want to have sex with Hajun. Not here—somewhere without people… Please. Auntie can’t hold back anymore. Hurry and put Hajun’s cock into Auntie’s filthy pussy. Please… somewhere it’s just the two of us.”
As always, Auntie had read my intention and given me exactly the answer I wanted, stressing her wish for privacy.
“Alright. If our Saea wants it that badly, as her master I have to grant it. Get ready and let’s go.”
The second I finished speaking she yanked her pants back up.
“Cha Saea. Your answer?”
“Th-thank you. Master Hajun.”
I stroked the head of the woman now speaking so politely.
“Lunchtime’s already over and I’m getting hungry, so let’s eat first.”
“I… I brought lunch boxes in the car. While I was packing Seoa’s I made yours too. Want to go to the car?”
I’d half expected it ever since she mentioned bringing Seoa lunch, but hearing Auntie herself say she’d prepared a lunch box for me too felt good. She stared at me with desperate eyes, clearly dying to get out of the library as fast as possible.
“Auntie, this is actually kind of touching. You even packed my lunch—I might have to call you to campus more often.”
“…You’re really…”
“Alright, let’s go.”
Once Auntie had gathered her things I gently took her hand, laced our fingers together, and led her out of the library. Just before we left the reading room I deliberately passed right by the guy who’d spoken to her earlier, giving our joined hands a little swing so he’d notice.
Know your place. Don’t eye what’s mine.
Still holding hands tightly, we cut across campus toward the 100th Anniversary Hall and its basement parking. Midway there Auntie suddenly stopped. I turned to look at her and found an unexpected expression. I’d been sure she’d be scowling, but Auntie Saea was gazing at me shyly, face flushed pink.

Our eyes met for a moment; then she seemed flustered by her own reaction, waving both hands as she spoke.
“D-don’t get the wrong idea! It’s just… holding hands on a university campus like this is… a first for me. I felt flutter—no! …W-we shouldn’t be doing this!”
“Huh? What are we doing right now? We’re just holding hands on the way to the basement parking lot.”
“B-but if other people see us, it’s too… you know…”
I hadn’t expected this reaction at all. A thirty-nine-year-old woman with a college-age daughter getting this embarrassed?
Wait—just now she almost said she felt fluttery, didn’t she?
I took her hand again gently while she floundered, too shy to finish her sentence.
“Alright, you don’t have to deny it so hard. Until we reach your car we can just pretend to be a campus couple. You can think of it as part of the contract if you want.”
“Uh… uh?… Mm.”
What’s this? I thought she’d hate it and refuse… Don’t tell me Auntie Saea actually started liking me after I fucked her? Hmm… that would be a bit of a problem.
