My Stepsister Thinks I'm a Pervert!

Jodie nearly chokes on his tongue when Melissa announces she'll be sunbathing naked in the yard. He plays it cool—sort of—but the second she leaves, his feet carry him straight to the window. There she is, sprawled out, tits pointing skyward, legs parted just enough to show pink. Jodie ducks into the bushes for a better angle, heart hammering like a cheap drum. Melissa rolls onto her stomach, arches her back, gives the grass a slow grind. Then she twists, catches his eyes peeking between leaves, and smirks. "Busted, perv," she calls. "Get out here." He steps out red-faced, shorts tented. Melissa props herself on one elbow. "Strip. Fair's fair." Jodie shucks off his shirt, his jeans, finally his briefs. His cock springs free, heavy and already slick at the tip. Melissa whistles low. "Not bad, little bro." She crawls over on hands and knees, wraps warm fingers around him, and swallows him down in one smooth motion. Wet heat, tongue flicking, cheeks hollowing—Jodie's knees wobble. Melissa pulls off with a wet pop, turns, plants her palms on the towel. "Behind me," she orders. Jodie lines up, pushes in, and watches her plush ass ripple with every slap of his hips. Her pussy grips tight, slick, greedy. He grabs her waist, thrusts harder, and her big tits swing beneath her like pendulums. She moans, reaches back to spread herself wider. "Deeper—yeah, just like that." They flip. Melissa straddles him, sinks down slow, then rides like she's got somewhere to be. Her fluffy lips stretch around his shaft, clit grinding against him on every drop. She plants her hands on his chest, bounces faster, breath hitching. "Fuck—Jodie—I'm—" Her whole body locks, pussy pulsing, a rush of wet heat soaking his lap. She laughs, shaky, then slides off and drops to her knees again. "Mouth," she says, opening wide. Jodie stands, strokes once, twice, and spills across her tongue in thick pulses. Melissa swallows, licks the corner of her lip, grins up at him like the cat that got the cream.
