It had been almost 2 years since Heather and I had started having sex. Over the past few months things had kind of tapered off though, the thrill and excitement slipping away, especially with our parents knowing. They'd tease on occasion but would otherwise leave us to it, as long as we'd kept it in our rooms they really didn't care. Lucy never joined us again, she got herself a job out of state and was wrapped up with her new girlfriend too. Heather had also moved out into a small apartment, we had fun having noisy sex in her living room a few times then she managed to get herself a boyfriend. Out of respect for her I took a step back and went back to my porn and masturbation, my crazy work schedule making it too tough to find anyone.
One morning though, she called me and asked me to head over to her place, she sounded a little angry but wouldn't say why over the phone. When I got to her apartment she pulled me inside, she was wearing black stockings and suspenders but was otherwise naked, I grinned as I gazed at her. I went to speak but she put her finger over my lips and pulled me by the hand into her kitchen.
"So, questions later, you're here to fuck me, cum in me then you're going to leave," she said quietly, already rubbing my cock through my jeans.
"What about Steve, we agreed to not fuck while you have a boyfriend Heather," I replied.
"I said, questions later."
Heather undid my jeans and pulled them down as she got to her knees, it didn't take her long to suck me to hardness. She stood up and leaned over the counter and looked back at me as she rubbed her pussy. I knew better than to argue with her and pushed my cock inside her. I hadn't jerked off in over a week so being in Heather's pussy again was a treat, the thrill of fucking my younger sister returning and I knew I wouldn't last long. I held on to her hips as I fucked her, her tight pussy felt amazing and I soon felt the familiar tingling in my balls.
"I... I'm close Heather," I gasped.
"Push it in nice and deep when you cum baby.." she replied.
I did as she asked, almost lifting her feet off the ground as I pushed deep inside her then erupted, my cock swelling as I pulsed my seed deep inside her pussy. She whimpered in pleasure and I felt her pussy tighten as my orgasm set her off too but as soon as I'd finished cumming she stood up and kissed me on the cheek.
"You have to go now, pull your pants up and leave, I'll talk to you later."
I was still catching my breath as she almost pushed me out the door, my cock still dribbling the cum I hadn't finished spraying into her, I sat in my car confused and drove home. I was laying on my bed when Heather called me.
"Hey, I hope you're not mad at me," she said.
"No, just a little confused, first sex I've had in almost 4 months so it felt good but why the cum and go?" I replied.
"I can't tell you right now, I need you to do the same tonight and tomorrow then I'll explain okay?"
"Just come to your place, cum in you then leave?"
"Yes."
"I don't know sis, I feel like I'm part of something I shouldn't be."
"If you do it without asking questions I promise I'll have you stay over for a weekend and we can just fuck like we did when we first got together and I'll even let you have anal. I promise I'll explain too okay, I just need you to do this."
"Fine, you know I can never refuse you."
"Thanks bro, I love you."
"Love you too Heather."
She texted me about 8pm, told me to head over, included a topless picture of her and told me same rules, fuck her then leave. I was already semi hard when she pulled me into the kitchen, she kissed me passionately then had me fuck her. I lasted a little longer that time but the surreal situation and the mystery behind it had me excited and I was soon pushing in deep to fill her with the contents of my balls. Like that morning, she pulled off my still dribbling cock, had me pull up my pants and boxers then I was out the door, my cock still semi hard by the time I was driving away.
The next morning after I'd showered she texted me again, just asked me to come over to her place. My excitement vanished when she answered the door fully dressed though, she hugged me, gave me a quick kiss on the lips then led me by the hand into her lounge. I got a little worried when her boyfriend, huge guy about twice my size, was sitting on the couch.
"Hey Marcus, good to see you man," he said, shaking my hand.
"You can wipe the worried look off your face sweetie, take a seat," said Heather, sitting next to Steve.
"What uh, what's going on?" I asked as I sat down.
"So. Do you remember Clara?" said Heather.
"You mean the Clara who got me kicked off the football team because she lied about buying xanax from me?" I asked.
"Yup, the very same bitch. Well, she's been trying to fuck Steve for years, she started a rumor that Steve was cheating on me with a girl in his work, even faked a text exchange that she sent me a screenshot of, claiming "I'm sorry to show you this, I used to like him but I thought you should know" and I stupidly fell for it. After Tom cheated on me I wasn't thinking straight and went straight to anger and wanted to teach Steve a lesson. Yesterday when I had you cum in me, Steve was blindfolded and tied to my bed, I went in and sat on his face and made him eat your cum," said Heather.
"When she wouldn't let me fuck her afterwards I made her tell me why and she told me. I gave her my phone to show her I wasn't lying, I don't delete my messages and had replied to Clara that I am with Heather and don't cheat. Heather took some convincing but she came clean and told me she was convinced I'd cheated and wanted to teach me a lesson before dumping me," said Steve.
"Well, turns out my kinky boyfriend here has always had a fantasy of eating another mans cum from my just fucked pussy but wouldn't want some stranger to fuck me so when I told him he confessed he actually enjoyed it. He made me tell him who it was and got super turned on when I told him about us," continued Heather.
"She told me everything, I'd never been so turned on in my life, I used to read erotica about that but having a girlfriend who actually fucked her own brother is awesome for me," said Steve.
"So why am I here again and what has Clara got to do with anything? She loses again right, she didn't break you up," I replied.
