A Bathroom

We still had a couple of minutes before the bell to end lunch rang, so I knew the halls would be empty. I quickly lead Karen to a nearby girl's bathroom and then into one of the stalls.

"I can't believe you expect me to do this in a bathroom, Master!" Karen said.

"Do you want to cum or do you want to stay at the edge for the rest of the day?"

"...I need to cum. I'm losing my mind! Please fuck me with your big cock, Master!"

"That's more like it. Turn around and bend over with your hands on the door."

"Yes, Daddy." She turned around and put her hands on the stall door, sticking her butt out at me. I could still smell her desire. She was **** for me to fuck her pussy. But that wasn't my intention.

"Ooooh, you're going to need this!" Angela said. I didn't see her but suddenly a jar of Vaseline appeared in my hand. "Remember, she's never done anal before. Also, I went digging in her mind. She really thinks anal sounds gross, so if you make her cum from it, she'll be even more humiliated!"

The bell rang signally the end of lunch and the start of 4th Block. I put some Vaseline on a finger and tried to stick it in her asshole but she flinched and moved away from me. "Hey! What are you doing? I told you I don't take it in the ass!"

"I said I was going to fuck you. I never said which hole! Now, unless you want me to fuck your ass dry, hold still."

"...Okay, fine." I guess that registered more of a choice than a command. When I reached for her asshole again, she didn't move away but still couldn't help clinching up.

"Relax your asshole."

"Yes, Daddy." Finally, I was able to slide my finger in. Her asshole was tight! I could tell she really didn't want this from how much she was whimpering. Then, I worked two fingers into her ass. "Owwwwww! Is that your cock?"

"No, just my fingers. You'll know when it's my cock." I fingered her ass, stretching it out as well as applying a good amount of Vaseline. Then, I covered my hard cock with it. "I'm going to fuck your ass now. Spread your ass cheeks and beg me to fuck your ass." I pulled out my phone to record this.

"Yes, Daddy." She spread her ass and looked back at me with a smile. "Please, fuck my ass, Daddy! I need your big cock inside me! Use my virgin ass as much as you want!" Then, the smile went away replaced by a look of lust and desperation. "Just make me cum! Please! Fuck my ass if that's what it'll take!"

"Well, I can't refuse an invitation like that!" I put the head of my cock against her asshole and pushed. It took a bit but finally the head popped in causing her to gasp. Then, I very slowly pushed the rest of my cock into her ass.

"Oh my god! Your cock is actually going in my ass!" Her ass was really tight and felt amazing. Still, not quite as good as Angela's.

"There's two reasons for that," Angela said. "One, I'm a sex demon. I could give you a handjob and it'll be the best handjob ever. Two, she's an anal virgin. She doesn't have any experience with anything going in her ass. So, you can't really compare us fairly."

Once I was all the way in, I lifted up her top and squeezed her big tits from behind. "Put you hands back on the door until we're done and tell me how this feels."

"Yes, Daddy. It hurts, damnit! Please take it out and fuck my pussy instead!"

"Sorry, no condoms so no can do! Now, if you can cum from anal sex, you can cum without my permission. However, it will only take away some of your sexual tension. When I cum inside you, you will cum and release all of your sexual tension."

"Yes, Daddy." I started to fuck her ass with long, slow strokes. Before long, her whimpers turned into moans.

"It's starting to feel good, isn't it?"

"No, of course not, Master!"

"Answer me honestly."

"Yes, Daddy. Yes, it's starting to feel good. Why is it feeling good? What did you do to me?"

"I didn't do anything. You just like getting fucked in the ass like a whore!" With that, I started moving faster.

"Ah! Ah! Oh God!" Then, I heard a door open and stopped moving. "Wait! Someone is here!" she whispered.

"Well then, I hope she doesn't hear you." Then, I started fucking her hard. She tried her best to keep her mouth closed but then something neither of us expected happened. She came.

"Uhhhhhhhhhhh!"

"Are you okay in there," the person in the bathroom with us asked. I recognized her voice as Sally, a girl in my 4th Block Calculus class.

"Yeah, I'm OKAY!" As Karen replied, I started fucking her hard, again. "I'm JUST a little AH! Constipated!"

"Riiiiight. You have fun in there." With that, I started fucking her faster

"Ah! Ah!" She couldn't keep quiet anymore and Sally was now in the stall next to us. Having this unexpected audience really turned me on. Finally, I thrust all the way inside and filled her ass with cum. This was the condition I had given her. "I'm cumming! I'm cumming! I'm CUMMING! AHHHHHHHHHHH!" Her whole body shook before she went completely limp in my arms. I sat down on the toilet, pulling her into my lap and held her there as I pumped her ass full of cum.

"Damn, girl! I'd ask whoever's in there with you to give me a turn but I need to get back to class." With that, Sally flushed, washed her hands, and left. Karen sat on my lap barely conscious with my softening cock still in her ass.

I spanked her ass to get her attention. "Okay slut, get up and clean my cock with your mouth."

"Yes...Daddy..." She slowly stood up and let my soft cock, and some of my cum, fall out of her ass. Then, she turned around, got on her knees, and started sucking my cock. I think at this point she realized what she was doing because her eyes went wide. "That's enough. Put your number in my phone."

"Yes, Daddy." She got up and did as I said. I saved her number as "Slut". "Go home and await further instructions. If anyone asks why, tell them you're feeling sick."

"Yes, Daddy. Can i have my panties back now?"

"Hmmmm, no."

"You're a jerk, Master." Then, she grabbed her backpack and left.

Grabbing my bag, I peaked out to make sure the coast was clear and then went to my Calculus class. "John, why are you a half hour late?" my teacher Mrs. Howard asked.

"I had to use the bathroom. I was a little--" I looked at Sally. "--constipated." Her eyes went wide as she realized what I meant.
