Tim slammed his textbook closed--done with his Trig homework, finally.
Now he thought he'd go for a swim. He stood and stretched, listening to his stiff joints crack and pop, then went into his closet, got naked and pulled on a colorful pair of swim trunks that sported a Porsche motif--race-cars and the prancing horse logo along with the 'Porsche Racing Team' printed around the waistband.
His mind ran back the last few days. the weekend had been a whirlwind of unbridled lust, it was like all the frustration of going 18 years before getting it had kept him hard all weekend. Alexa was a fantastic lover, she had taught him how to hold back, riding him with expert movements, how to move in concert with her to increase their shared pleasures. She was going to see him tonight, and he could hardly wait. They were going to go out to the lake and fuck like rabbits in Dad's cabin. Her lovemaking was a dream, she was energetic, eager, and very hot for his cock. The ideas of what they would do brought on his imagination.
He entered the pool house by the rear door, grabbed a towel off the rack, and walked through the French doors to the pool area. He was still looking down, grinning at his tented trunks as he wandered over to the lounge chairs, intending to drop his towel off before taking the cool plunge.
"You repugnant little pervert."
Tim stopped with a start, jumping at the sudden sound of his step-mother's voice. His mouth dropped open in surprise as he looked up to see Linda reclining with a frozen drink in her hand, buck naked but for a pair of sunglasses and a floppy pink hat, oiled brown skin gleaming under the hot sun.
"Wha--!?!"
"Fucking Peeping Tom," she spat with a look of disgust, although she did nothing to cover her nudity.
"I-I'm not...I wasn't...I didn't..." Tim sputtered.
"Uh-uh-uh-uh," Linda stuttered mockingly. "Not what? Not peeping at your mother? Not sneaking around trying to see me naked? Not standing there with a hardon? Pervert."
"I didn't even know you were out here!" Tim protested, moving his towel to cover his crotch.
Linda raised a foot to kick the towel away, then put her toes on the bulge. "And I suppose that's not your dick? Drop your shorts--Let's see!"
"Huh?" Tim muttered, taken aback by the sight of her plump little pink pussy lips exposed to the bright sunshine as she carelessly held her leg out.
Linda snorted derisively, hooking the leg of his shorts with her agile toes and pulling them down. Tim, mesmerized by her twat, didn't even notice until his bone popped free. He shifted his feet and let the trunks fall to his ankles.
"So, it is your dick, such as it is..." Linda removed her shades for a better look as she laughed out loud. "Pathetic little thing, isn't it?"
