Threesome with Girlfriend and Her Sister

This is part 2, for part 1: I Fucked My Girlfriend’s Sister

*****

The drive home was fifteen minutes but I barely remembered it. Every second I was replaying what had just happened: the feel of Flora grinding on my lap, the sound she made when I put my hand in her shorts, the way she laughed while I came inside her, like it was just some cosmic joke. My hands shook a little on the wheel, probably from the comedown, probably from the adrenaline of knowing what I’d just done. Or maybe from the knowledge that Isla would know. Girls like Flora didn’t keep secrets for long.

My mom’s car wasn’t in the driveway when I pulled up, so I headed straight for the shower. I scrubbed myself raw and changed into fresh clothes: plain black t-shirt, joggers, hoodie over the top, like that would erase the smell of sweat and sex and betrayal. I was still hard by the time I got out, a leftover from the hour with Flora, and I did nothing about it. Part of me wondered if this was what guilt felt like. It felt like wanting to jerk off to the memory, and also wanting to punch myself in the face.

I got a text from Isla at 2:14. Done with work early, can I come over? Isla added a second: I brought us fries. I stared at the screen, wondering if Flora had said anything. Probably not. She’d said she wouldn’t tell. But that kind of secrecy felt borrowed, like a jacket you’d have to give back before long. I said yes and then waited for my girlfriend to show up.

The doorbell rang fifteen minutes later. Isla stood on the stoop, hair straight and still damp from her after-shift shower, in a pale blue tee and shorts. She held a greasy brown paper bag in one hand and looked exactly like the girl I was supposed to want. I tried to smile and not think about her sister.

Isla was 5’6″ with an oval face, soft cheeks, full lips, and warm brown eyes that narrowed slightly as she looked at me. Light olive skin with a few faint freckles across her nose, dark brown hair falling past her shoulders. Even in the simple tee and shorts her hourglass figure was obvious: narrower waist, wider hips than Flora’s, thick thighs. The thin fabric clung enough to show the weight of her full D-cups and the hint of cleavage at the neckline.

She walked in, dropped her bag on the kitchen table, and did this thing where she looped her arms around my waist and pressed her face into my chest, sighing like she’d just gotten home after months away.

“Hey,” she said, muffled.

“Hey.” I hugged her back, more out of habit than instinct.

She rocked on her heels and looked up at me, eyes sharp but warm. “You help Flora?”

“Yeah. Got the chair moved.”

“Did she help at all?” Isla’s tone was dry, skeptical.

“She helped,” I said.

She grinned. “With her muscles? Or just with her mouth?”

I choked a laugh. “Both. She spotted me.”

“I’ll bet she did.” Isla peeled herself off me and fished a fry out of the bag. “Did she wear a bra this time?”

I felt my face go red. “Yes, but she took it off.”

“She’s a menace,” Isla said, like she was talking about a neighbor’s cat. “She flirt with you?”

I shrugged, went for a fry myself. “A little, maybe. She said you called me wiry.”

Isla made a face like I’d just confessed a felony. “Oh my god. Did she, like, hit on you?”

The air in my chest got thin. I heard my own voice from ten feet away. “Not really. I mean, she joked a lot.”

“Did she touch you?”

I took a long time chewing. “Not… not on purpose.”

Isla watched me. The look on her face was less suspicious and more curious, like she was writing a story and waiting to see how the next chapter turned out.

“She ever talk about me?” Isla asked.

“Sometimes.”

“Yeah? Like what?”

I shrugged. “Just normal sister stuff.”

Isla snorted. “There’s nothing normal about Flora. She’s, like, her own species.” She sat, criss-cross on one of the kitchen chairs, and shoved more fries in her mouth. “She ever say anything about sex?”

My stomach flipped. “Maybe once or twice,” I said.

This made Isla light up. “She’s projecting.” She paused, leaned forward on her elbows. “Wait, do you think she’s pretty?”

The question landed like a test. I’d never lied to Isla outright, and if she was fishing for something, I didn’t want to hand her bait. “She’s cute,” I said.

“Is that why you’re acting so weird?”

I blinked. “I’m not acting weird.”

She tilted her head, all fake innocence. “You’re being cagey.” She poked my thigh with a fry. “If she flashed you, you can just say.”

“She didn’t flash me,” I said. Which wasn’t technically a lie, unless you counted the tank top. Or the part where she straddled me. Or the fact that I’d had both hands on her tits, and then both hands inside her.

Isla smirked. “You ever jerk off thinking about her?” She said it like she already knew the answer.

I coughed, almost choked. “No.”

“Uh-huh.” She reached over and brushed my hoodie down, then froze, eyes narrowed. “What’s that?”

“What?”

She leaned in, fingers tugging at the seam of my shirt. “You have glitter on your neck.”

I touched the spot. “Maybe from the armchair? She had a weird throw blanket on it.”

Isla’s voice dropped. “That’s her makeup. She has, like, sparkly setting spray. She does it when she wants to look hot.”

I had no reply. My hands went cold.

Isla let it hang for a second, then kissed me. Her lips were soft, and she pressed harder than usual, like she was testing the way I tasted. She pulled away and licked her lips, eyes locked on mine.

“You taste like strawberries,” she said.

I almost said, “That’s not possible.” But then I remembered Flora’s lip gloss, and how it had smeared on my mouth.

“Isla—”

She put a hand on my chest and pushed me gently until I sat in the chair, her body in my lap now, light and solid at the same time. “Do you want to fuck me?” she asked, deadpan.

I shook my head, voice gone. “No. Not now.”

She bit her lower lip, not hurt, not even annoyed. “Did you fuck my sister?”

My mouth opened and nothing came out. She reached for my hands and held them in hers. “Did you?” she repeated, calm and so direct it was almost merciful.

“Yes,” I said. The word was out. The world didn’t end.

Isla looked at me for a full five seconds. Her face didn’t change, but her eyes did this subtle flicker, like a puzzle piece sliding into place. She nodded. “Did you like it?” she asked.

I tried to breathe. “Yeah. I’m sorry. She started it. She—”

Isla squeezed my hand, cutting me off. “Did you come inside her?”

The question shocked me so bad I almost laughed. “Yeah.”

Isla gave a little huff, the corners of her mouth tugging up. “She’s on the shot. Don’t worry.”

That brought me up short. “You knew she’d try to fuck me?”

Isla shrugged. “She told me before you even got here she was going to try. She said, ‘He’s hot, I want to see if he’ll do it.’ I didn’t think you’d actually cave.” She leaned back, head resting on my shoulder, arms looped around my neck. “You’re a bad liar, Ash.”

I was sweating. “You’re not mad?”

Isla shook her head, a little smile working its way up. “No. I’m turned on. Is that fucked up?”

I stared at her, unable to process. “Why?”

She grinned. “Because Flora’s not the only freak in this family.” She slid off my lap and went to her bag, unzipped the side, and pulled out her phone. She scrolled for a second, then handed it to me.

I saw a video thumbnail of two naked girls on a bed, the camera angle grainy and handheld. It took me a second to realize it was Flora and Isla, both of them naked, kissing. The video started: Flora lying on her back, Isla between her legs, tongue licking. Flora’s hands in her sister’s hair, guiding her. The sound was muffled but obscene: wet, breathless and horny.

My jaw dropped. Isla watched my face with a grin, waiting for the moment I realized it was real.

“When?” I asked, still locked on the screen.

She shrugged. “Last month. But we’ve done stuff for, like, a year. She wanted to make sure I’d be okay if she seduced you.”

“She said you’re into threesomes,” I said. “I thought she was joking.”

Isla rolled her eyes. “She says a lot of things. But when she’s horny she’s honest.” She took the phone back, closed the video, and tossed it on the table. “So? Are you mad?”

“No,” I said. “I’m…” I didn’t know the word. “Confused?”

She smiled. “Good. Because if you want to fuck both of us, all you have to do is say it.”

I felt something unlock in my chest. “I want to.”

Isla laughed, the happiest I’d seen her in weeks. “You’re lucky I like you.”

She glanced at the clock, then at me. “You know Mom’s working late tonight, right?”

“Yeah.”

She licked her lips, this time on purpose. “Good. Because you’re driving us back to my house. Flora’s been texting me since you left. She wants round two.”

I grabbed my keys without thinking. Isla was already out the door, hair bouncing, texting as she walked.

The drive back was fifteen minutes, but this time I remembered every second.

*****

Flora answered the door in a ratty Cal Poly tee that hung just past her hips, no shorts underneath, bare-legged and pink-toed. Her hair was up, messy, the way it got when she’d been lying in bed all afternoon. When she saw both of us, her face went shiny with joy.

“Holy shit. Both of you?” She gave Isla a look that was equal parts delighted and competitive. “I thought you were mad at me.”

Isla rolled her eyes. “Why would I be mad?”

Flora pretended to think. “Um. Maybe because I fucked your boyfriend?”

Isla shrugged. “Not my boyfriend anymore … he’s ours.”

The look on Flora’s face was priceless: shock, then worry, then a sly suspicion that maybe she was being punked. She was watching Isla so hard that she barely noticed me, which was a first. Isla stepped in, kissed her on the cheek, and dropped her shoes by the door.

“You’re such a dumbass,” Isla said. “I’m not mad. He’s cute, you’re hot, it was bound to happen.”

Flora grinned. “Are we sharing?”

“That’s the idea,” said Isla, heading for the stairs. “But this time, I get first dibs.”

Flora looked at me, then at Isla, then at me again. “Does he know about us?” she whispered.

“He knows everything,” Isla called from halfway up.

Flora shot me a look like, Really? and then a look like, Oh my god, is he into it? It was the same look I’d seen right before she’d unzipped my pants.

We followed Isla upstairs, Flora right in front of me, her thighs flexing as she went, the hem of her shirt riding higher with every step. At the landing, she turned and fake-tripped, landing against me, then let herself stay pressed a fraction too long.

“You’re not mad?” she whispered, again, voice right in my ear.

I shook my head. “Not even a little.”

She nuzzled into my shoulder and made a tiny pleased sound, then scampered after her sister.

Isla’s room was bigger than Flora’s and cleaner by a mile. White sheets, gold throw blanket, candles on the desk that made everything smell like vanilla. There were three giant polaroids stuck on the headboard: two of Isla, one of both sisters together, cheeks squished, tongues out, middle fingers raised at whoever took the shot.

Isla was sitting on the bed cross-legged, still in her shorts and tee, phone in her lap. She glanced up and said, “Door.”

Flora closed it, then stood there, shifting from foot to foot, waiting to be told what to do. Her eyes were locked on Isla. Whatever power dynamic they had, it was clear who called the shots.

“Take your shirt off,” Isla said, barely looking up.

Flora did, slow and showy, like she was stripping for a hidden camera. She shimmied the tee up, exposing her flat stomach and the faintest tan lines on her hips. The shirt went over her head, mussing her hair, and she flicked it at me. Underneath she wore nothing. Her tits were as perfect as I remembered: heavy, high, round, nipples still swollen from the afternoon.

Isla finally looked at me. “Your turn.”

I pulled off my hoodie and tee at once, heat prickling down my spine. Flora ran a hand down my stomach, grazing my waistband, and gave me this smirk that said she remembered exactly what my cock looked like.

Isla’s eyes lingered on Flora’s tits, then on mine, and then she crooked a finger. “Come here.”

Flora climbed onto the bed and settled between Isla’s legs. The vibe shifted instantly from tease to real. Isla brushed a strand of hair out of Flora’s face and kissed her, open-mouthed and slow. Flora melted into it, moaning into her sister’s mouth, hands gripping Isla’s thighs. Isla guided Flora’s face down, and for a second I thought they were going to 69 right there.

Instead, Isla said, “Show him how you like it.”

Flora shivered. She got on all fours and crawled to the edge of the bed, right in front of me. She looked up, doe-eyed, then pulled down my joggers. My cock sprang out, already hard as hell, and she wrapped her lips around the tip before I could even exhale.

Her mouth was hot and wet, and she took me deeper on the first go than most girls manage in a month. She gagged, spit leaking, but didn’t break eye contact. Her fingers curled around the base, stroking while she bobbed her head. Every second she kept her eyes on mine.

Isla knelt behind her on the bed, pressed close against Flora’s ass. She palmed Flora’s cheeks, spreading them, then slid one hand underneath to toy with her pussy. Flora moaned around my cock, the sound so hot it made my knees weak.

“She’s good, huh?” Isla said.

“Yeah,” I said. I tried not to thrust, but it was impossible.

Isla leaned down and whispered something in Flora’s ear. Flora popped off my cock, panting, then turned to kiss Isla. There was a string of spit from my tip to Flora’s lip, and Isla licked it off, eyes on me the whole time.

I thought I would explode from the sight.

Isla motioned me onto the bed. I sat back, legs spread, and the sisters came at me together. Flora licked up and down my shaft while Isla sucked my balls, then they switched, then both mouths at once. It was obscene, the way they fought over who got more, pushing each other out of the way, then laughing, then going even harder.

“Fuck, that’s insane,” I said.

“Don’t come yet,” Isla ordered. “You have to last.”

They let go at once. Flora wiped her mouth, then leaned in and kissed me, tongue pushing into my mouth. I could taste myself on her, and the taste was instantly addictive. Isla knelt beside me, palming her tits through the thin tee, her nipples so stiff you could see the shape through the fabric.

“Can I fuck you?” I asked Isla, barely able to keep my voice steady.

She grinned. “You can fuck both of us. But start with me.”

She slid off her shorts, revealing smooth skin and a tiny patch of dark hair, trimmed neat. I slid a finger down, felt her soaked and ready. Flora watched, then bent and sucked Isla’s nipple through the shirt, making her gasp.

I lined up and pushed inside. Isla was tighter than Flora, wetter, and so hot I could barely keep from losing it in the first second. Flora kneeled beside us, hands on Isla’s ass, watching my cock disappear into her big sister.

Isla moaned, her breath hitching. “Harder,” she said, biting her own knuckle.

I fucked her harder, Flora squeezing my thigh every time I bottomed out. Flora started kissing Isla again, licking her lips, her cheeks, even her ear. Isla gripped the sheets, hair sticking to her face, staring at me like she owned me.

After a minute, Isla rolled over, dragging me with her so I ended up behind her, fucking her doggy style. She buried her face in the pillow, arching her ass high. Flora slipped under her, head between Isla’s thighs, tongue out.

“Eat me while he fucks me,” Isla panted.

Flora did, hungrily. I could feel Flora’s tongue against my cock every time I pushed in, the three of us joined in one messy, sweat-slick knot. Isla was moaning so loud I worried the neighbors would call the cops.

We kept switching. Flora climbed up and rode my face while I fingered her, her thighs tight around my head. Then Isla took over, stroking me into her mouth until I was close again. After that they lay side by side on their backs, legs tangled, grinding their pussies together while I knelt between them and stroked myself, watching.

Finally, Isla pushed me back on the pillows and climbed on top, riding me. Flora cuddled up next to us, kissing Isla, then me, then Isla again. Her hand trailed down my chest and between Isla’s legs, rubbing her clit while I thrust up. Isla started to shake, her whole body going rigid. She looked down at me, eyes wild.

I grabbed her hips and slammed up, Flora’s hand never slowing. I exploded, groaning, every muscle in my body locking up. Isla threw her head back and came, clenching around me so hard I thought I’d pass out. “Oh fuck, that felt good,” Isla said, coming off my cock, her pussy gaping wide open.

“I want the creampie,” Flora said with a smile, slid down, and immediately put her mouth on Isla, licking up the mess. She didn’t stop until she’d cleaned every drop, her tongue creamy white and my cum mingled with her sister’s pussy juice was all over her chin and lips.

After, the three of us lay there, limbs tangled, sweat cooling on our bodies. Flora curled into my right side, head on my chest, hair in my mouth. Isla wrapped around my left, arm draped over my stomach.

“Is this your dream, or mine?” Flora said, voice muffled.

Isla pinched her. “It’s his. But you can share.”

I couldn’t answer, too blissed out for words.

Flora lifted her head, lips swollen, eyes bright. “You know we’re going to ruin you, right?”

I smiled, pulled her closer. “Promise?”

Isla laughed, warm and mean. “You have no idea.”

I let myself drift, two perfect bodies pressed against me, and thought, this is heaven.
