You lads are actually pathetic, but since I'm feeling nice I'll teach you fuckwits the easy way to do it
Step 1;
Set how much she resists to 1 and how long you'll last to one, how quickly she cums is irrelevant
Step 2;
Wave your hand over her cheek a little bit, then pull at her knees until her legs are spread
Step 3;
Pull up the shirt BUT LEAVE THE PANTIES ON
Step 4;
In the centre of your screen, go down into the black area and wave your mouse around in that area until your penis appears erect
Step 5;
Press space and hold left click on your penis, you'll see it sit there pressed against her, it will let you cum inside her this way, repeat this until on the right hand side, 'in' is at about 30, then you can pull her panties off and actually cum inside her
