Slow.. just take it easy and go with the flow.
Here's a fun tip for all you guys while spurting the jizz. Click on your “excitement meter” quickly when the orgasm is just about over… you know, to reload the cum. If you do it right, it gets stuck and the cum keeps spurting and spurting and spurting. You can change actions and you keep jizzin'… if you change poses though it resets. I glazed Robot Girl like a donut that way… almost complete coverage.
But… don't do it too long. If you do, the balls on your avatar start to shrink and eventually they get sucked up into the body and if you keep going like that it forms a singularity which creates a black hole and swallows not only you, but your lover and the entire room. Then you have to reboot.
Have fun!
