Jen stared at her hairy crotch with the massive sausage attached... and felt an urge. She felt an urge she had never felt before and she needed to Jack it off. With two hands she gripped onto her meat and began stroking as it became harder, she kept pumping until a massive spirt of cum flew out causing her to moan in pleasure.

When Jen woke up she saw her dick wasn't erect... but it was bigger than she remembered. She got up and it dragged through the semi-wet cum and went over her beach ball sized hairy testicles andropped her oversized hairy bush, her dick had to be about 5 feet long now. She inspected her body, and she went a little overboard... her breasts were covered completely in chest hairs, her armpit tufts stuck out of the sides, her arms and legs were dark with hair, her knuckles had hair on them, hair grew down her back, and she was growing a mustache with a beard.
