Alexa Payne, the naughty stepsis, is back at school, but her mind is elsewhere – on her stepbrother and his massive cock. She's daydreaming in class, her hand snaking up her skirt, fingers rubbing her clit through her panties. The teacher catches her, sending her to detention. But Alexa has other plans. She sneaks into the janitor's closet, her heart pounding. Her stepbrother follows, finding her bent over a mop bucket, her big ass on full display. He spanks her, leaving red handprints on her flesh. She moans, pushing back against him. He unzips, sliding his cock into her wet pussy. She gasps, her big boobs swaying as he fucks her hard, her uniform riding up to reveal her big ass. He pulls out, creampieing her, his hot cum dripping down her thighs. They collapse together, breathless, before Alexa wipes herself clean and returns to class, a satisfied smirk on her face.
