This is great and playful for your guy or girl

Start off by laying down. It creates this sexy mood and makes him/her want to kiss you more.
Kiss him/her lightly and get agressive but don't tongue, yet.
Once you guys are deep into a passionate makeout (without tongue) pull away really fast.
Then ask him to guess what you're thinking of..a letter or number or something that you know he wont think of & tell him that everytime he gets it wrong he has to kiss you on a different part of your body.
Let go wayy into proportion and then make them stop to make out with you. I gareentee they'll love it boy/girl. It makes them hornier if you suck a little in the more tender parts and be really agressive by playing with their hair or slideing your hands over his/her body.
