This is a sex move, so get consent. You’ll need some red and yellow dyed lube, and a bitch with an innie pussy. So you get her pants off, lay her on the bed with her legs extended into the air and bent back towards her face. This should expose her
pussy lips perfectly. Then you take your dick, and put it in between her
pussy lips, but not in, then you put the dyed lube on top of your dick, and slide your dick
back and forth. That’s basically it.
