"Her fingers digging into the rigid muscles of his thighs, she let him direct the pace of her mouth moving up and down the rampant cock wet with her saliva. She lost track of time, aware of only the man using her for his sexual gratification and the subsequent arousal that made her thick fluids trickle down between her legs. He pulled her mouth off his shaft, shifted closer to the edge of the seat and, in a strained, husky voice, told her to suck his testicles.
She enclosed the taut sac within her mouth, her lips tickled by his dark, wiry pubic hair. She suckled him, rubbing her tongue across the underside of his sac, tracing patterns all over him with the pointed tip. He cursed, drew her head back and, gripping his cock in a tight fist, rubbed the tip of it across her lips. She obediently parted them, gave him a single lick and took him inside once more.
He shouted her name when he climaxed and salty liquid hit her tongue and the back of her throat. Katarzyna swallowed. When his body stopped jerking, she released him from her mouth and, per his order, licked him clean."
