tell her "image yourself waiting in line for a rollercoaster. just any roller coaster. how long are you in line for?" the answer she says to this is the answer to how long she likes foreplay. It's a mind trick using something called kokology. if she says there is no line, it means skip the foreplay with her because she just wants to fuck.
Later text her saying "I'm going to fuck the shit out of you tomorrow. Be ready"
-that way she gets turned on and she'll be thinking about getting fucked by you all day, leading to her having a greater orgasm. It also won't make anything awkward when you go over to her house and shove her head on your cock, then your cock in her ass, cause she knows its coming.
-if she sends "oh really

" you know your in.
-if she sends "uhh...." then you have been reading her wrong and your fucked.
hour and a half before you see her
-jerk it 2 times. maybe 3. it takes longer for you to "reload" after you do.
knock on the door. come in.
-she's been waiting like 12 hours to get fucked so get to it. make out . work your way down to her pants. then use "white tiger tantra" its basically the best way to finger a girl that i know of. you can prolly find all the details just by googleing it. if you can't find anything on it, just do what you normally do.
-remember her answer to the roller coaster question, and just keep fingering her, and eating her out, until you estimate that the time is up. have her on the floor or bed.
-while your going down on her, come back up and put her hands together over her head, make out with her, look her in the eye and bring your right hand down from holding her hands above her head, and just let the palm of your hand touch her arm pit. I know it sounds weird, but it will drive her crazy. she wont laugh, she'll moan. tickle spots become turn on spots.
-make your way back down then strip naked and do this

maybe even smack her ass a few times. extra hard if she has daddy issues. then tell her to get on top of you and turn around so you two can do this

just alternate after when you feel like it.
-I chose those positions cause these give her the whole dick inside her. so you wont have to worry about fucking in different ways or dick insecurities.
-also while your fucking her, just tell her whats going through your mind. Like.
"god your so tight"
or give her commands like
"I'm gonna fuck you until you cum baby, then you're gonna lick the cum off my dick. say it! say your gonna lick the cum off my dick"(when girls are horny, they'll say yes to anything. mwhaha!)
But yea hope this helps you out dude, good luck!
