The apartment was quiet except for the low hum of the laptop fan. Mia sat cross-legged on the couch in nothing but an old tank top and panties, her finger hovering over the download button. The file name glowed on the screen: free download sex film girl and girl. She clicked it anyway, heart thumping, knowing her older sister Lena was due home any minute from her shift.
Lena walked in five minutes later, kicking off her boots. "What are you watching?" she asked, dropping her keys. Mia didn't minimize the window fast enough. The video started playingtwo women, one clearly older, the other younger, tangled on a bed, moaning as fingers disappeared between spread thighs. Lena froze, then laughed low. "That's some family shit right there. You into that now?"
Mia felt her face burn but didn't close it. "It's just a download. Free. Looks hot." Lena came closer, leaning over the back of the couch. Her breath hit Mia's neck. "Hot? Those two look like they could be sisters. You ever think about that?"
The air thickened. Mia shifted, feeling the wet spot already forming in her panties. Lena's hand dropped to her shoulder, squeezing. "Show me the good part," Lena said, voice dropping. She climbed over the couch and sat right next to Mia, thigh pressing against thigh. The women on screen were grinding now, one riding the other's face, juices shining on her chin. Lena's fingers traced down Mia's arm and landed on her bare leg. "You like watching that? Girls in the same family getting nasty?"
Mia nodded, spreading her legs a little. Lena didn't wait. Her hand slid under the waistband of Mia's panties and found her slick folds. "Fuck, you're soaked already." Two fingers pushed inside without warning, curling hard. Mia gasped and bucked against them.
On screen the younger woman was coming loud, shaking, while the older one licked her through it.
Lena pumped faster, thumb rubbing Mia's clit in rough circles. "Bet you'd let your big sister do this to you. Finger this tight cunt until you scream." Mia grabbed Lena's wrist, not to stop her but to push her deeper. The download kept playingnow the women were scissoring, clits grinding together, wet sounds filling the room. Lena pulled Mia's tank top up and sucked a nipple into her mouth, biting just enough to sting.
Mia came hard, clenching around Lena's fingers, thighs shaking. But Lena wasn't done. She yanked Mia's panties off, pushed her back on the couch, and buried her face between her legs. Her tongue was relentless, licking from asshole to clit, sucking the swollen nub until Mia's hips lifted off the cushions. "Taste so fucking good," Lena muttered against her. "My little sister's pussy."
Mia reached down and grabbed Lena's hair, grinding against her mouth. Another orgasm built fast. The video had moved to the two women using a strap-on, the younger one taking it deep while calling the other "sis." Lena slid two fingers back inside Mia while sucking her clit and Mia broke again, crying out, flooding Lena's tongue.
They didn't stop. Lena stripped fast, climbed on top, and rubbed her own wet cunt against Mia's. Their clits slid together, slick and hot. "Fuck me back," Lena ordered. Mia thrust up to meet her, both of them panting, skin slapping. The free download sex film kept looping in the background while the real thing happened on the couchtwo sisters using each other until they were shaking and dripping, coming together in a messy, loud grind.
When they finally collapsed, sweaty and spent, Lena kissed Mia slow and deep, tasting herself on her tongue. "We should download more of those," she said. Mia smiled against her mouth, already reaching for the laptop again.
