Tiffany trains him too

Jenna lay by the pool, her bikini top barely covering her perky breasts as she soaked up the sun. She was 19 now, old enough to know exactly what she was doing as she "accidentally" let the strings of her top slip off her tan shoulders, exposing herself to her 18-year-old stepbrother Jake who was floating lazily in the pool.

The young man's eyes went wide as saucers as he stared at Jenna's creamy flesh. She giggled to herself, knowing that at his age, it didn't take much to get the boy worked up. She let her top fall away completely, her rosy nipples hardening in the warm summer breeze.

"Oops, silly me!" Jenna cooed as she sat up, adjusting her top back into place. "Guess I need to tie this tighter." She smiled coyly at Jake who quickly averted his eyes, a deep blush coloring his cheeks.

Just then, the sliding glass door opened and out sauntered her mother Tiffany. The 37-year-old bombshell was wearing a scandalously small bikini that struggled to contain her massive tits and round bubble butt. Jake's eyes nearly popped out of his head as he took in the sight of his stepmom's body.

"Well hello there," Tiffany purred, eyeing her son like a hungry lioness. "Enjoying the view, baby?" She deliberately bent over as she set down her drink, giving both teens a perfect view of her thong-clad ass.

Jake sputtered, sinking lower into the water. Jenna smirked, loving that her mom was both equally brazen and teasing the poor boy. She decided to really push it.

"You know Mom, you're looking so hot today," Jenna said with a giggle. "I bet you could totally have any guy you wanted, huh?"

Tiffany laughed, a throaty sound. "Oh honey, I could have anyone I wanted, any time." Her eyes found Jake's. "Anyone at all."
