There's also a slightly different version from the
ESI / UCF war. I don't know for sure which was first.

"Fucking Fiona" by Rotec (more from this author)
The game uses pics from Party Girls (or vice versa) and is supposed
to be a demo but we haven't been able to find a different version.

*sigh* Games like this one lead to frustrated women I tell you! You just
hack away at the F7 key to bring your partner to orgasm. As if it was

to keep it up. If you're too fast... I bet you know what happens. ;)
