The tension had been building for weeks. Ever since Cory caught her stepson, Mark, staring a little too long, a little too intensely. She knew he was curious, and frankly, so was she. Today, the air crackled with unspoken desires. He'd asked to borrow her car, and she'd agreed, with a sly smile, telling him to 'be careful' as she tossed him the keys. But when he returned, she had a different lesson in mind. An anal education, she thought with a wicked grin.
"Thanks, Cory," Mark said, a little flustered under her gaze. He was a handsome kid, broad shoulders filling out his t-shirt, but she saw the nervousness in his eyes. "The car was great."
"Oh, I'm glad," Cory purred, stepping closer. She was wearing a silk robe, barely concealing her big boobs. "But I think you deserve something a little more...educational."
Before he could respond, she reached out, her fingers tracing the outline of his big cock through his jeans. He gasped, his eyes widening. "Cory...I don't know if-"
"Shhh," she whispered, leading him to the bedroom. The blinds were drawn, casting the room in a soft, sensual light. She pushed him onto the bed and straddled him, the robe falling open to reveal her naked body. He reached out, his hands cupping her busty breasts. "This is what you want, isn't it?" she asked, her voice husky.
He nodded, unable to speak. Cory leaned down and began to give him a blowjob, her lips teasing and tormenting him until he was hard and throbbing. Then, she pulled away, her eyes locking with his. "But that's just the beginning," she said, reaching for the lube.
Mark watched, mesmerized, as she slicked up her ass. He'd never done anal sex before, but the way she was presenting herself, the raw desire in her eyes, made him want to try anything. She positioned herself on the edge of the bed, her ass facing him. "Ready for your lesson, stepson?" she breathed. He nodded eagerly, and with a deep breath, he thrust forward.
Cory cried out, a mixture of pleasure and pain. He pushed deeper, filling her completely. She moaned, her body arching with each thrust. It was tight, intense, and unbelievably arousing. He could feel her muscles clenching around him, drawing him in. The sensation was electric. He couldn't hold back, and with a final, powerful thrust, he cum in ass.
They collapsed onto the bed, breathless and satisfied. Cory looked at him, a mischievous glint in her eye. "Well, Mark," she said, "I think you passed with flying colors. But there's always more to learn."
