It's a wonder more females in the game don't get pregnant when MC walks by.
After fucking Diane, or Daisy, or Jenny, odds are the Wheel of Fate is going to come up Pregnant more often than not, especially if MC's taken that pill, and that little sperm cell will have a clear shot of making it to the egg cell.
Fuck Diane and the wheel comes up Pregnant, you'll be able to screw her all the way through the first half of her pregnancy.
However, once the wheel comes up Pregnant for Daisy or Jenny, that's it for sex.
Rather than pull out and ejaculate (kinda fucks up the screwing, if you know what I mean), as soon as you hit the Spin button on the Wheel of Fate, be prepared to hit the Ctrl key on your computer to immediately enable another spin if you don't like the spin's result (like Pregnant). Gotta be quick, though.
The Ctrl key trick also works with the Spin the Bottle game at the beach with the girls. Last spin? Wanna fuck'em all? Hit the Ctrl key until you get the desired result. Again, gotta be quick.
