My coworker spasms into a nympho while I make love to the hilt her curvy silhouette

A young, curvy coworker with whom I had chosen to share a passionate intimate moment for the first time suddenly transformed from a sane woman into a nymphomaniac. Her 18-year-old brunette beauty and large bosomy best assets are on display as she gets fucked in the doggy style. There is no reversal of fortune and the climax is that she is completely drenched in cum.
