My Evil X Sister-in-law

Until now only two people on the planet knew this story. You better show some appreciation by getting off!

Kelly was my Ex’s sister. We were only a few years apart while my ex was 7 years younger than me.

When we first met I hated her. She was snobbish, drank too much and was never nice to her sister, Sheri.

Kelly was a sports medicine physical therapist and worked for a AAA mlb baseball team. She loved the attention she got from the players and as long as I’d known her she’s never had a steady boyfriend.

Kelly was 5’3 straight long blonde hair and green eyes. She had natural huge breasts and a pretty small waist. Her ass was very tight from pilates or whatever gym kick she was on. This was the absolutely best ass possible in a pair of yoga pants.

At this point I really hadn’t interacted much with her other than some holidays etc. I asked Sheri to set up an evaluation due to an injury I sustained. Let’s just say playing golf for the first time and trying to crank every tee shot 250 yards wasn’t smart!

THE OFFICE
Upon showing up to my appointment, Kelly’s assistant had me fill some paperwork out and sent me back. “What’s up sis! Should I drop my pants now? Or…” I joked. “No one wants to see that thing you perv!” she shot back.

We chit chatted and Kelly went through some range of motion tests on my shoulder. She gave me some exercises to do and told me to lay off the “Happy Gilmore shit” for awhile.

“So how is that perfect sister of mine doing?” she asked. “From the limited amount of time I get to see her great!” I said. “She comes home pretty late from work sometimes and then just passed out!”

“Be careful she may be banging random guys after work! She can be feisty” Kelly said. I laughed and asked “Wait do you have another sister that I don’t know about?”

Kelly smirked a bit and started to say something. I couldn’t quite catch it and asked “C’mon let’s hear it. I know you’re gonna say something bitchy”. “Ok dickhead, if I tell you this story you better NEVER tell her I told you! I’m fucking serious!” she said with a hard look.

THE SIS STORY FROM KELLY’S MOUTH
“Ok I was in college and Sheri came to visit me. She was 18 and had a nerdy boyfriend. Like you!” she chuckled. “Fucking funny! Go on!” I pressed. “Well he didn’t want her to come but I insisted that she must since it was a big Frat party weekend. She drank a little but had not much experience partying. Not COLLEGE experience anyway.”

“I dragged her to some parties and she was having fun and drank lots of jello shots, which had 150 proof liquor! She wasn’t sick though and we went back to my dorm”

“A guy I was hooking up with regularly came over to the dorm and hung out. Sheri was drunk and very direct. She asked Brandon, my boy toy if he planned to stay over and ‘bone her sister’.

“Maybe! Why will that freak you out?” he asked. Just then there was a knock at the door. “OPEN” I yelled. A girl peeked her head in and said “Kelly some dude is asking for you or maybe your sister..I’m not sure”. “Oh jesus send up the nerd!”

“Seriously Sheri? You drunk dialed him didn’t you? We’ll that dork isn’t gonna be the only sober one here so go get him some of that punch from the SAE guys next door. Tell them Killer Kelly sent ya!”

“In walked Shawn all 150lbs of him. ‘Well hello Shawn!’ I said. Come join the party! Your sister is out fucking an ENTIRE fraternity!” Shawn looked like he was gonna really cry. “Dude I’m kidding she’s getting some drinks for you.”

“I knew I was being a bitch but I was pretty buzzed and I guess I didn’t care. Right in front of both Shawn and Brandon I pulled the sun dress I was wearing over my head. I covered my tits with my hands and went to the dresser. I grabbed a babydoll nightgown and slid it on. Both of the guys just stared.”

“Just then Sheri came in with a huge pitcher of punch mixed with various fruit. Her shirt was literally soaked in the front. ‘ You fucking lush, grab a shirt from my drawer’
Sheri went into the bathroom dragging Shawn with her.

“I told Brandon that if he wanted to fuck me he better pretend that they weren’t even here and turn out the lights. I really wanted to freak Shawn out. Our bed was perpendicular to the other with a half wall in-between. Basically you could see half of both beds.”

“Brandon was a good dude but his cock was the boss of all of his decisions. I had my hood pierced and the slightest flick of the tongue sent me screaming. I commanded him to get to work on it. TMI Tyson?” I asked.

I was taking all of this story in without a peep for fear that she wouldn’t continue. “Ah nope, please continue ya freak” I jabbed.

“Whatever, just keep it in your pants. Anyhow I was loud. I cum loud, I fuck loud. Brandon literally came while going down on me once because of the nasty things I blurt out while I cum.”

“I heard the door open to the bathroom and some whispering.”

“Your sister is so loud Sheri, what the fuck?” I heard Shawn say. “Should we stay here?” he asked.

“Sheri didn’t say anything but she turned on some music. I grabbed Brandon’s head holding it still for a second and looked around the corner. Shawn was standing there naked and his cock was hard and thick like a soda can.”

“Still wanna hear more ya pussy?” Kelly paused. “I’m good lets hear it” I said apprehensively.

“Brandon was no longer doing his job and his face was now on the bed. He was super drunk and now snoozing away. Sheri was enthusiastically sucking Shawn’s cock and I could see everything. Every once in awhile he would glance over and smile at me. Then she stopped sucking.”

“That’s not gonna happen” I heard my sister say. “It hurts WAY too much” she explained.

“I hopped up, totally naked and went into the bathroom. I grabbed some cherry lube and tossed it on their bed.”

“I could hear them laughing like two drunk idiots. ‘Shawn drag your ass over here and stand in front of me!’ I said. I heard some whispering and more laughing.

“Just then Shawn was standing there 5 feet from my bed. His cock was unbelievably hard. I then heard Sheri let out a big burp and laugh hysterically.”

“The room was pretty dark but I could Sheri peering through a small opening under her pillow. I grabbed Shawn’s ass with both hands and pulled him to me. He resisted a little until his cock brushed my cheek”

“I barely licked the head of his cock and laid down, putting a pillow under my ass. ‘Shawn get me a towel’. I said. Sheri was still watching. Shawn came back and handed me a towel.”

“Stand there and watch me” I commanded. “I shifted my hips and put the towel underneath my ass. I opened my legs and showed him my entire pussy. Slowly I started working the ring on my clit and it started to swell. I could see him mouth ‘what the fuck’ as he watched me.

“I started moving faster and faster on my clit, flicking the ring until I screamed. A quick stream shot from my pussy and I could feel my juices pouring onto the towel.”

“When I looked up Sheri was now standing behind Shawn stroking his cock. She had the cherry lube all over her hands and was working his cock vigorously.”

“Without thinking about just how fucking twisted it was I sat up and opened my mouth. Sheri nudged him right up to my mouth. I could see his cock starting to twitch and I rested his cock on my tongue. Every ounce of cum in the world seemed to shoot out of that huge monster!”

“I swallowed every drop and smacked him in the butt. You’re welcome sis!’ I said like the bitch that I am.”

“They passed out and when I awoke the next morning they were both gone. Sheri left a note on my desk. ‘Love you sis. Thanks for a fun night you slut. Give Brandon a kiss from me! Love Sheri.”

“Well there ya go sport. Think about that one tonight when Sheri passes out early again!” Kelly teased.

This was just bthe beginning of the EVIL Sister-in-law saga. TBC
