Bottom's Backup-Plan 

Fake-fucking. It is when the receiver, or bottom, lays with legs together and straight with the torso either on their side or stomach. The other person, the top, comes in from behind and will be thrusting, using the perineum of the body. (Position can be done with the bottom on their back, and top entering from front side, with the bottom lifting up their balls to give access to their perineum.)
There is no actual penetration of the body being preformed with this position. When laying on the side, it should feel like a relaxed natural cuddle session. Adding a little bit of lubrication of whatever form desired, in addition to the bottom flexing their thighs and relaxing their thighs, will stimulate the top in the similar sensations that they would receive from anal penetration.

So if the bottom wasn't prepared or had to tap out, this still would allow the bottom to take care of the top and never let him walk away with blue balls.

Key note!! Bottoms...do not try to do the work, don't wiggle the hips, do not bring your knees up, your body should be lined up the same as if you were laying flat on your back on the floor.

I could not clean myself out before my hookup, but he didn't know any difference because of the Bottom's Backup-Plan. He still thinks he finished inside of me.

back up plan 

Haplessly taken for granted just because it’s not “exciting enough” or it’s “too good”. A plan that will only be referred to when all else fails. When you become a back up plan you should
figure out a way to hit them hard with the realization that you won’t always be there for them to walk all over you when they have no one else to go to; that you’ve got your own plans too. Otherwise, you my friend, will forever remain stuck in that phase.

Person #1 : Hey bro so what’s our plans tonight?
Person #2 : Who said “we” had plans? Check back with me in an hour or two.
Person #1 : What, so now I’m a back up plan?
