Michael stood by the bed, his face buried in the nape of Betty's neck, his lips kissing her skin fervently as he inhaled the scent of her hair.
His hips thrust rhythmically, as if trying to merge completely with her, their genitals secreting fluids with each passionate stroke, pulling out copious amounts of lubrication.
Michael hadn't fully removed his pants, nor had Betty completely taken off her underwear, and her nightgown's hem was caught between them.
As they melded together wildly, the fluids soaked Michael's trousers, Betty's panties, and the hem of her nightgown, leaving visible traces of their intense activity.
"Ugh... oh..." Michael grunted as he worked, exhaling like a marathon runner, his breathing timed with his thrusts, allowing him to maintain a vigorous pace.
The sound of flesh slapping against flesh echoed in the room, "smack, smack, smack..." while Betty's buttocks lifted with each thrust, causing waves of lubrication to splash out.
