Interesting

Lilly looked up as her husband, Leonard, came home from work.
"The children told me something interesting today," Lilly began, her manner still proper and her accent still upper class British even in her new body. "They said they saw my body wearing skimpy clothes and prancing around like a...a tart."
"Now, dear," Leonard said, "They say you shouldn't keep tabs on your pre-Shift body for just that reason."
"It simply isn't fair. I worked hard on my figure and that little trollop just gets to steal it and walk away."
"This figure isn't so bad," Leonard tried to console her.
Lilly snapped her book shut. "I know. And now I have no qualms about you doing with it as you wish. If she is going to have intercourse in my body, I shall have intercourse in hers."
Leonard was secretly overjoyed. He'd been dying to touch his wife's graceful new black figure ever since she got it weeks ago in the Great Shift. At last he kissed her, stroking her smooth skin, before leading her to the bedroom and getting her naked. 
Lilly was hesitant at first, but Leonard coaxed and complimented her until she straddled him and sank down onto his cock. A little moan escaped her lips as she began riding him, faster and harder, her tits bouncing up and down as the pleasure shot through her body, soon ending in a crying climax as Lilly enjoyed her first orgasm, a much more intense experience in this stranger's body than she'd ever felt in her own. She came down excited and warm.
"Let's do it again," she enthused.
