My Stepsister’s Unexpected Relationship Rules

Amanda sat across from me in my living room, her eyes fixed intently on mine. “She jerked you off?” she asked, her voice laced with a mix of surprise and curiosity.

“Look, I’m not trying to upset you,” I replied, choosing my words carefully. “I just don’t want to lie to you about anything.”

“No, I’m not upset,” Amanda said with a laugh. “Just surprised. I thought she wasn’t supposed to touch you because that would be considered ‘cheating’ on her boyfriend.”

“Well, you did ask,” I said, raising an eyebrow. “You said you wanted to keep things casual, right?”

Amanda’s expression turned skeptical. “Yeah, but I didn’t know some other girl was gonna jack you off after we went on a date!” She sneered, her tone playful but also laced with a hint of competitiveness.

“I didn’t plan it,” I said, shaking my head. “She just showed up. But like I said, I’m not trying to hide anything from you.”

Amanda’s gaze lingered on mine, her eyes searching for any sign of deception. “Look… I have a job interview, but I’ll be back in an hour or two,” she said finally, her voice hesitant. “Do you wanna hang out later today?”

“Sure, but I’m kinda broke right now,” I said, trying to gauge her interest. “Do you wanna just come over and watch a movie or something?”

“Sure,” Amanda replied, a hint of a smile playing on her lips. “But I’m gonna go now. I’ll be back later.”

As she left, I couldn’t help but feel a sense of excitement. I had no idea what the rest of the day would bring, but I was eager to find out.

A couple of hours later, Amanda showed up at my doorstep, looking sporty and cute in her wind shorts and volleyball tee. “Did you pick out a movie?” she asked, her eyes sparkling with enthusiasm.

“Yeah, I was thinking we could watch ‘Eternal Sunshine of the Spotless Mind’,” I said, smiling. “What do you think?”

Amanda nodded, and we settled into the couch with some popcorn and sodas. As the movie began, she turned to me and asked, “Is that girl gonna show up here tonight?”

“I have no idea,” I replied, trying to keep a straight face. “But even if she does, I’ll handle it.”

Amanda’s gaze lingered on mine, her eyes searching for any sign of reassurance. “And what will we do if she does?” she asked, her voice barely above a whisper.

“I’ll tell her that you’re here, and she’ll probably just go away,” I said, smiling reassuringly. Amanda nodded, looking relieved.

We made it about halfway through the movie before we gave in to our physical desires. As we kissed heatedly, I couldn’t help but feel a sense of excitement and anticipation.

Before long, I was on top of her, my hands roaming over her body as we kissed. I slid my hand up her stomach, resting my palm over her small, firm breast outside of her shirt. She showed no desire for me to stop, so I began to gently squeeze it, feeling her moan into my mouth.

I took it as a good sign and decided to move my knee up between her thighs, applying gentle pressure. She was still moaning, so I slipped my hand under her shirt and then pushed up the sports bra she was wearing underneath. I began to roll her soft nipple between my finger and thumb, feeling her moan more.

She then felt my hand slide down her stomach, resting over my crotch. I pulled her shirt up, exposing her pale breasts. They were not as amazing as Renee’s, but they were still very nice.

I leaned down and drew her small pink nipple into my mouth, sucking on it hard. She continued to moan as I felt her hand slip inside of the waistband of my shorts. I bit her nipple as her exploring fingers found my cock and wrapped around it.

She was stroking me long and slow, and I reached down to unbutton and unzip my shorts for her. Now her hand was free to glide up and down with ease.

All was going well, so I then reached down between her thighs and pulled the crotch of her wind shorts over to the side. I slid my fingertips under the elastic of her panties and pulled them aside as well. When I placed my fingers on her exposed cunt, I found it swollen and dripping wet!

That turned me on a great deal. She was clearly into everything that was happening, so I slid down the couch and out from between her legs. I then grabbed the waistband of her shorts and yanked them down along with her panties. She eagerly lifted up off the couch to help me slide them off.

Before I could even get them off of her legs, she had leaned up and ripped off her shirt and sports bra, dropping them both on the floor, leaving herself completely naked. I followed suit and yanked off my shirt.

Her icy blue eyes were burning with lust as I dropped forward and wrapped my lips around her gushing cunt. She moaned again as I slid my tongue rapidly across her clit.

Her thighs clenched around my head, and I was squeezing one of her breasts in each hand as I dug into her mound with my tongue. I had been taught well. In just a couple of minutes, I felt her body tense up, and she let out a primal scream as her juices gushed over my tongue.

I waited for the bucking to subside and slowed my movements to a gentle lapping. She lay perfectly still, staring up at the ceiling. I finally rose up to look her in the eyes.

SHE LEANED UP AND KISSED ME ON THE MOUTH, DESPITE THE FACT THAT IT WAS GLISTENING WITH HER JUICES. “YOU ARE A FUCKING GOD!” SHE MOANED.

I rose up to my knees, letting my open shorts fall around my knees. My cock was sticking straight out. “Just give me a second,” she sighed.

She then got up and went straight into the bathroom. I was surprised to hear the shower head hum to life. I walked into the bathroom naked and found that she had gotten into the shower.

“What are you doing?” I asked through the curtain.

“Sorry,” she said. “I don’t mean to be weird. I just needed to have warm water rushing over me after that.”

There was a pause. “Did you take classes in that or something? That was fucking amazing.”

“I read a lot of books,” I said as I pulled the shower curtain open to have a better look at her.

“What book was that in?” she asked, her eyes sparkling with curiosity.

“I don’t remember,” I said, smiling. Amanda looked down at my cock, which was still hard from our earlier encounter.

“Oh my god,” she smiled, her eyes locked on mine. I watched as the water cascaded over her tight, muscular body, and I was struck by her beauty.

Amanda was a runner, and it showed. She was toned and firm everywhere that mattered. Her breasts were probably a small C-cup, and her ass was muscular and firm. It was the first time that I saw her naked body in all its glory, and I was very pleased with how she looked.

She finally turned off the water, and I handed her a towel. She stepped out of the shower, and I couldn’t help but feel a sense of excitement and anticipation.

She didn’t say anything, just smiled as she grabbed my cock and pulled me toward the door. She led me back to the couch in the living room, where she sat down next to me on her knees.

She then climbed onto the couch, her eyes locked on mine. “I want to do something for you,” she said, her voice barely above a whisper.

“What do you want to do?” I asked, feeling a sense of excitement and anticipation.

“Just watch,” she said, smiling.

She lowered her head, and I felt a surge of excitement as she took my entire cock into her mouth. It was wet and warm, and it felt amazing!

She continued to deep throat me, and I was amazed each time I watched her lips start at the head of my shaft and go all the way down until her lips were touching my balls.

“Holy shit,” I moaned, feeling a sense of pleasure and excitement.

Once my cock was soaking wet, she kept the head in her warm mouth and began to slide her fist up and down the shaft. She worked it slowly, but her grip was firm and very tight.

Any time it began to feel dry, she would go all the way down and coat it with spit. During all this, I could feel her tongue swirling around the tip as she delicately stroked me.

The sensation was incredible, and I couldn’t help but say, “It looks like you read a lot of books too.”

Amanda laughed, and I was struck by the way a pretty girl looks when she smiles while she’s got your cock in her mouth.

She worked me like that for what felt like twenty minutes, and I was amazed by her skill and technique.

At first, I kept thinking that there was no way that I could cum from what she was doing. But after about twenty minutes, I felt a deep, intense orgasm beginning to build up in me.

My legs began to shake, and I felt my load coming. I moaned aloud, and at that moment, Amanda quickened her pace.

Before I knew it, my fingers were clawing the couch cushion, and I was sending my hot load down her throat. She then went all the way down again, and I had no doubt that I was literally pouring my cum down the back of her throat.

I took her to my bed and we fell asleep, both naked and deeply satisfied.

I woke up at 2:30 am to the sound of my phone chiming. I picked it up and saw that I had a new text from Renee.

RENEE: Come let me in. Want to play with you.

Amanda rolled over with her eyes squinted. “What’s going on?” she asked, her voice barely above a whisper.

“Renee’s here,” I said, sitting up on the edge of the bed.

“Shit,” Amanda sighed. “Can’t you just ignore her?”

“I’ll just be a minute,” I said, standing up and putting on a pair of flannel pajama pants.

I flipped on the porch light and saw Renee standing there, looking drunk and disheveled. I opened the door and she immediately threw her arms around my neck and kissed me deep and hard.

“I want to play with you again,” she said, her voice slurred.

“Not tonight,” I said, trying to gently push her away.

Renee reached out and placed her hand over my cock, gripping it through my thin pants. “Don’t you want me to make you cum again?” she asked, licking her lips.

“Amanda’s here,” I said, trying to reason with her.

Renee’s face fell, and she stepped back, looking hurt. “Fine,” she said, turning on her heel and walking away.

I watched her go, feeling a sense of relief and guilt. I knew that I had hurt her, but I also knew that I had been honest with her.

The next day, I got a text from Renee, asking if she could come over when I got off work. I thought for a moment before responding.

ME: Sure.

I drove home with a mix of eagerness and dread, wondering what would happen when Renee arrived.

When I got home, Renee was sitting in her car outside, looking nervous and anxious. I got out of my car and headed inside, locking the door behind me.

“I’m sorry about last night,” I said, trying to sound sincere.

“Why did you lock the door just now?” I asked, trying to gauge her mood.

“Because I don’t want Amanda coming in while I’m here,” she replied, her voice laced with bitterness.

“She won’t,” I said, trying to reassure her.

“So, she knows all about us and all the stuff that we do together?” she asked, her arms crossed.

“Yes, and you know all about her,” I said, trying to reason with her.

“And she spent the night last night?” she asked, her voice rising.

“Yes,” I said, feeling a sense of guilt and responsibility.

“And she knows that I’m here and she’s okay with me coming over?” she asked, looking confused.

“She’s not my girlfriend, Renee,” I said, trying to explain. “She doesn’t have cause to feel anything about it.”

Renee looked at me, her eyes searching for any sign of deception. “Did you have sex with her?” she asked, her voice barely above a whisper.

“Not yet,” I said, trying to gauge her reaction.

Renee’s face fell, and she looked at me with a mix of anger and hurt. “As though you’re going to?” she asked, her voice rising.

“Are you jealous?” I asked, trying to reason with her.

Renee said nothing, but her expression spoke volumes. I knew that I had hurt her, but I also knew that I had been honest with her.

Finally, she looked up at me and asked, “You swear you didn’t have sex with her?”

“Not that it’s any of your business, but fine,” I said, trying to sound sincere. “I swear I did not have sex with her.”

Renee nodded, looking relieved. “So what happened if you didn’t have sex?” she asked, her voice barely above a whisper.

“We watched a movie,” I said, trying to downplay the situation.

But Renee’s eyes sparkled with curiosity. “Then what?” she asked, her voice rising.

“Then we started kissing again,” I said, feeling a sense of guilt and responsibility.

Renee’s eyes trailed down as I unzipped my fly, and I knew that she was still hurting. But I also knew that I had been honest with her, and that was all I could do.

Renee walked into the room, a sly grin spreading across her face as she closed the door behind her.

‘I think it’s time we got to the bottom of things, don’t you?’ she said, her voice husky and confident.

I raised an eyebrow, intrigued by the sudden change in her demeanor.

‘What do you mean?’ I asked, trying to sound nonchalant despite the growing tension between us.

‘I mean, I know you’ve been lying to me, and I know you’ve been thinking about me in ways you shouldn’t,’ she said, her eyes locked onto mine.

I felt a flush rise to my cheeks as I realized she was right. I had been drawn to her from the start, but I had been too afraid to act on my feelings.

‘How did you know?’ I asked, trying to play it cool.

Renee laughed, a throaty sound that sent shivers down my spine.

‘I know you, Jack,’ she said, her voice dripping with sincerity. ‘I know you’re not the kind of guy who would just lie to me without a reason.’

I felt a pang of guilt as I realized she was right. I had been lying to her, and I had been hoping to avoid the truth.

‘Okay, fine,’ I said, throwing up my hands in surrender. ‘I’ve been attracted to you from the start. I just didn’t know how to handle it.’

Renee’s grin grew wider as she walked closer to me.

‘I think we can handle it together,’ she said, her voice low and husky.

I felt my heart skip a beat as she reached out and touched my face, her fingers tracing the lines of my cheekbones.

‘I think we’re just getting started,’ she whispered, her breath dancing across my skin.

I couldn’t help but agree.
