Sister In Heat: 18

Book:Crazy Pleasure (Erotica) Published:2025-2-5

Strangely, though these words might have been delivered with venom, Stephanie’s tone was more curious than coarse.
Tired of fiddling with my torn button-up, I removed it and sat down on the couch. “It started a few years ago,” I said.
Slowly, Stephanie nodded. She sat down in the opposite chair. “And you guys just kept at it?”
“No,” I said. “I stopped when we moved in together.”
“I always thought there was someone else,” she said. “I could feel it. Feel there was part of you elsewhere. But you’re saying you haven’t?”
“No,” I said. Part of me was ashamed, it’s true, but part of me was so relieved to finally tell her this – to tell anybody, really. “I didn’t think it was right.”
“But, John,” she said. “We had an… We agreed. It was okay.”
I jerked my thumb behind me at the dinner table. “You’re okay with that?”
“Well, no,” she said. “Coming home to see you fucking your sister like a crazy person is pretty jarring, but… that’s not what I’m talking about. I mean, who else are you sleeping with?”
“No one,” I said. “Until tonight.”
“But you could have. I have.”
That was always part of the agreement, but the way she said it… “What do you mean?”
She sighed, rubbing her fingers into her temple. “That’s what I came home to tell you. It’s… ugh. It’s my boss. I’ve been sleeping with him, off and on, since… Since I got this stupid job.” She leaned forward. “He’s an asshole, but he can get me this UN gig and… he wants me to go on this embassy trip with him and I came home to tell you I didn’t want to lie to you anymore. I can’t be with you if I’m fucking him regularly. That’s not right.”
“Uh-” I wasn’t sure how to respond. There were a lot of emotions in the air at the moment (not to mention the unmistakable smell of Moni and me still lingering in the air). “So you came here to break up?” I said.
“Pretty much,” she said.
“Why isn’t it right?”
“Because I care about you,” she said. “Yeah, we have permission to sleep around, but that’s… I dunno. I never thought it would work but it kind of has. I think I understand why, now. You love her, don’t you?”
I wasn’t sure what to say.
She just nodded, her eyes boring into me. “I always knew there was someone. That’s why I agreed to all of this. I figured as long as you had someone else you’d be okay with me not being 100 percent monogamous. But it wasn’t because you wanted to sleep around, it’s because you had someone you couldn’t be with.”
“It’s complicated,” I said. “But I always knew how I felt about you.”
“Yeah?” she said. She actually smiled. “You do love me a little bit, don’t you?”
“Always have,” I said. “This has never been easy for me.”
“It’s been very easy for me,” she said. “I always felt like I was taking advantage of you.”
“Oh, I didn’t mind that,” I said.
“I know,” she said, and smiled again. She let out a sigh and fell back against the chair cushions. “So you and your sister, huh?”
“Yeah,” I said.
“I guess maybe I can see that. I asked to see my brother’s dick one time on a bet. I’d be lying if I said I didn’t wonder how far that game of truth or dare could have gone if I didn’t have a meet that day…” A mischevious smirk formed on her face. “Hey, since we’re breaking up, you want to get a little weird with it?”
“Hm?” I said.
She leaned forward, and I knew what that expression meant. “Would you… um…” She bit her lip. “Would you do it, in front of me? I mean, could I watch?”
“You bet your million dollar ass you can watch.” It was Monica. She was standing behind the couch. I jerked to stare at her, dumbfounded. The girls were grinning at each other like a couple of hellcats.
“Well hold on,” I said. “I don’t know-”
“Oh fuck yes you do,” said Monica. “And don’t say you can’t get it up. I’m sure we both know that’s a lie.”
“Well-” I started.
Steph stood up to meet Monica at our doorway. “You do look pretty fucking cute, by the way,” my now ex-girlfriend said.
Monica didn’t wait for another line. She launched herself at Stephanie. The girl had a good couple of inches on her but the kiss landed. Moni went up on her tiptoes and Stephanie, after a surprised squeak, closed her wide eyes and gingerly wrapped her fingers around Monica’s blonde curls. I watched their tongues slide languidly out of their soft mouths to play with each others lips.
No, it was not hard getting hard.
Monica took Stephanie’s hand and led her into our bedroom. “I’ve always wanted to try this,” she said.
“Is that how this started?” asked Stephanie. “You wanted to fuck your brother?”
Monica crossed her hands over her chest, pulling her blouse and bra up and over her head. Stephanie gave an appreciative ogle at my sister’s wobbling breasts. “No,” Moni said coyly. “He just promised to help me fulfill a few dirty fantasies.”
Stephane grinned at me over her shoulder as she started to wiggle out of her pants. “Yeah, he’s good like that.”
Monica slid her skirt down her stockinged thighs. Stephanie started to undo her blouse but was already kneeling down where Moni was sitting on the bed. “Mm,” said Steph. “You’re so wet.”
“You want to taste him?” said Monica. She spread her legs. I watched my little sister, naked except for those sheer stockings, sweep Stephanie’s hair back as the girl descended on her lap. “Oh, fuck,” Monica sighed.
“Mmm,” Stephanie hummed into her pussy.
Monica laid back and let Steph eat her out. “Mmmmm…” Her eyes opened, slowly, and found me staring. She shrugged, indicating to me that I should just roll with it, and held out her hands. I unbuckled my pants and slid them down. Then I was on the bed, sliding into Monica’s arms and kissing her mouth.
“You’ve fought this for so long, baby,” my sister murmured between my kisses. “You see it’s okay, now?”
Steph emerged from between Monica’s thick thighs and climbed up next to the two of us. She kissed my forehead, then shifted a lock of my hair to the side. “If you want her, take her,” she said. Her mouth was glossy from Monica’s pussy, and it glimmered as she reclined against the pillows, her eyes entranced by my dick swinging over Monica’s squirming body. My cockhead pushed easily between her beautiful lips and my sister let out an ecstatic cry of fulfillment.
“Your brother just put his dick inside you,” Stephanie whispered into Monica’s ear. “Do you like that?”
“Mmmmyesss,” Monica whispered.
I gripped my sister’s thighs tightly and gave her a long, loving plunge. Stephanie watched my glistening cock squeeze inside her, licking her lips as it slowly pulled back out.
Steph couldn’t help herself. She took my sister’s cheek in her hands and gave her a long, slow kiss on the mouth. Monica returned it, even as her lower body met my every languid thrust. “What does it feel like to have somebody love you that much?” Steph murmured.
“It feels so good,” Monica told her. “So warm. Mm. So full.”
