When ur horny, the pussy...

Vaginas get deeper when we’re turned on
With sex on the mind, the vagina opens its doors.

Normally, the vagina is somewhere between 3 to 6 inches long, and 1 to 2.5 inches wide. After arousal, the upper portion of the vagina elongates, pushing the cervix and uterus slightly deeper into your body to make room for penetration

And they also change color
When you’re horny, blood rushes to your vulva and vagina. This can make the color of your skin in that area appear darker.

Don’t worry though, it’ll go back to its normal shade after sexy time is over.
