Joyce first

Xander was pissed at Joyce for running Buffy off, so he wanted to punish her. He put Joyce Summers in the Master PC, and her profile came up.

The first thing he did to her was plump up her lips and make them more sensitive. He then made her pussy and anus hyper-sensitive, and pushed the libido bar to the far right, making her a total nympho, but that was not punishment.

The punishment was that he totally removed her ability to orgasm. Her new sensitive lips, pussy, and anus would mean that any cock put in them would easily drive her to the very edge of orgasm, but she could never get over the edge, and this would frustrate the hell out of her.

Xander made Joyce's breasts a cup size bigger and firmer, and added inch to her butt and firmed it up. She would not notice the changes, and anyone who did notice would think she had plastic surgery.

Xander made Joyce want to show off her body by wearing very tight, revealing clothing and hat wearing bras. She would also do her hair and make-up like teenage jailbait as she now thought that was what could attract more men, and gave her a predilection for college aged boys.

Now that Joyce would be a shameless cougar hell bent on getting laid, but never being able to orgasm, Xander thought that should be hell enough for Joyce.
