Kayla: “But, it takes seven minutes to get all the way to the humanities building and the sixth floor has at least five different bathrooms.”
Aedan: “Slut’s don’t complain, they find solutions.”
Kayla: “Yes, little brother. I will be there.” I smile. I still have a little morning wood and the bitch is still playing. Then she texts me again.
Kayla: “I already see you’re getting good at this, Aedan. I knew you would be good. I’m on my way, little brother.”
I start a stopwatch timer on my phone. When I meant five minutes, I meant five minutes. And from where she is at, it would almost be impossible for her to make it.
3:30, 4:30, I hope she’s running. And right at 4:59, I hear the bathroom door pop open. I hear her stampede in the bathroom and she knocks on the stall door.
“Open up, open up! I know I made it.” I open the door and with a big shit eating grin, I prop the phone up to her face and say, “My phone says, 5:01. You were a second late. Time for your punishment.”
“Unnnnngghhh, come on little brother. that ‘s not fair.” I really love her daddy’s girl voice. Makes my cock throb.
“I don’t care for your pleading, Kayla.” I sit on the cover of the toilet, “Lay your stomach on my quads. Come, come.”
She does as she told and I can see she’s holding back a smile. she’s living for this. “Now you were a second late, that means 10 spankings for you.”
“Do as you please, little brother.” Smack, smack, smack. Each one getting increasingly harder. Each one making her smile just a little bit more.
When I’m about to go for the tenth smack, I hear the bathroom door open. I don’t know who it is, but I just whisper to her, “Doesn’t your mentor work on this floor? What if that’s him? What if he hears your little brother giving you a spanking.” Then wack, I give her the hardest one, the sound reverberating throughout the bathroom.
“Is everything all right in there? Do I need to call campus police?” Ha, it may actually be him. The voice certainly sounds familiar.
But, I just reply, “No it was a bug, don’t mind me.”
Whoever that was rushes out of the bathroom.
“We almost got caught, big sis. Time for your real punishment.” I unzip her jeans and pull them down her ass. I reach into her panties and sure enough, her sex is scorching hot and wet.
“I see you also have a kink for almost being caught.”
She moans out, “Yesss, I’m just a dirty bitch.”
“Yes, you are, big sis.” And I attack her clit with my fingers. Going fast, no playing around. Her eyes go wide and her mouth is open. She’s moaning faster and faster. I feel her about to cum and I pull my fingers back leaving her disappointed.
“You don’t get to come, bitch. I know you have class in two minutes. The person next to you is going to smell your sex for the entire hour. Now get up and leave my sight.”
She pulls up her jeans and she can’t hold back her smile. It’s like her dreams are coming true. She comes to my ear and whispers, “Good job, little brother, you should always leave your bitch in heat.” And she leaves just as she came, sprinting and in a hurry.
From that day on, I used my sister wherever and whenever I pleased. The student center, the bathroom of a club, in all her lecture halls just before class. She was willing to do anything. We went to one of her ex boyfriends hockey games and I fingered fucked here there as she watched her ex ride the bench. And just as she was about to cum, I yelled out that guy’s name and he turned back and watched my sister’s cumming face as she was orgasming and lightly squirting on my fingers. Leaving a mess in public, tisk tisk, I punished her for that later.
But the best, was when I went to her sorority house and fucked her on one of her sorority sister’s beds as the door was locked. I made sure the entire house heard her moan and scream. And the bitch squirted all over the sheets. I bet they hate her even more now.
My sister is still a bitch, but she’s also my bitch now. “Isn’t that right Kayla? You can stop sucking for just a second to tell these people.”
“Yes, yes, I’m a bitch for my little brother.”
“Good girl, now get back to sucking.” Today we are going to explore my bitch of a sisters third hole. I’m excited.
So, that’s all for now. Thanks for coming. Have a good one!
“Kayla is a bitch. She’s the biggest bitch in the whole wide world. Doo, doo, doooo. Isn’t that right, Kayla?”
“Mmmm hhmmmm”
“Good girl”
