Easy wall kiss.
If your partner is a guy,
When near a wall, take your signifgant other's hands in yours, wrap them around your back, and back him up into the wall, slowly and carefully, we don't want any bumps on the head.
Apply pressure with your hips, as if pinning him to the wall
Start out kissing open lips, no tongue
Then work your way to his neck
If you partner is a girl
Take her hands and put them around your neck
Place your hands on her lower back, just above her butt
back her up slowly into the wall
Pin her with your hips, and with one arm, lift her leg up to your side
Stroke it as you kiss her.
