so I have the house to myself this weekend and my GF is gonna come and stay the night.. she says she is going to "fuck my brains out and do things you never thought were possible." I'm scared yet extremly excited at the same time! WOOOOOO HOOO! Any suggestions/tricks I should try? I plan on jerking it like 3 times before she comes over so I could last longer, or is that maybe a bad idea? I normally last 10-20 minutes, I mean I can stop for a minute then go longer but average is 10-20 minutes straight through.. I want to do this for hours, like all night.. need tips!
