Superpower Growth?

The unusual setting and thrilling excitement made Jake feel a fresh thrill in sex he hadn't experienced in a long time.

Moreover, his aunt's legs were already trembling. If he didn't finish soon, she might collapse from exhaustion.

"Schlick... schlick..."

"Slap... slap..."

Jake prepared for his final assault, his cock pistoning violently, his hips working like a high-powered engine at full throttle.

"Oh... auntie... I'm gonna cum..." After hundreds of thrusts, the fluids in his aunt's pussy were nearly depleted. Her pink labia fluttered wildly from the impact, the white froth between his cock and her entrance now worn away into nothingness.

The hungry slit at the tip of his cock, stimulated by his vigorous movements, frequently brushed against her core, greedily sucking up the mysterious fluids coating the walls of her womb like a starving child desperate for milk.
