It's a random thing...Sometimes you get fist, other you get fuck.how to fist? how to cum inside mom with plan b pills?
Mainly you have to fuck Mom in the Kitchen (play with ass) in the morning on the weekend. If you did what you needed to do to get the buttplug (pharmacy) then you will use it to stop the cum from running out of her.
Later on catch her washing dishes and when it comes up use the Check Buttplug option...Make sure you have Lube!
But that option is a 50/50 chance as the other is just fucking mom no buttplug showed.
