-Get Sleeping Pills from the bathroom if you don't have them (UNLOCK and TELEKINESIS the first time, just TELEKINESIS after first). Use them on the wine by parent's bed.
-After using sleeping pills on wine. Go get tucked in, TELEKINESIS and LUST mom again. Watch her at night.
Do this 3 times in a row, there will be slight changes in the event. After the third time, she should masturbate in bed and Nina should mention you should be able to give her ideas on the computer.
-Afternoon, talk to dad in office so he leaves, computer, browser, leave. Mom comes in, she should choose to buy them.
-Wait 3 days.
-Go down to the foyer and see the package. Then return to your room
You should now be able to get the Fourth Power: WARP MIND.
