Do- Learn to control your left leg for clutching so it doesn't get all wobbly when I'm giving you head on the interstate.
Feel free to bite me, just don't draw blood
Smack that ass
Take off your socks! Nothing ruins it more for me than if you're totally naked but still have your socks on.
Don't- Worry about getting picked on cuz your floormates can hear me through the walls. They're just jealous.
Drip sweat on me, please....yuck
Ask for anything that you aren't willing to give/receive in return (ex. oral sex, anal sex, etc.)
Worry about your roommate walking in. I'm in my element and what he sees is his fault. The big black X on the door shoulda been enough warning.
ETA: Don't be afraid to laugh during sex. There's no way you can keep a straight face when our bodies make that farting noise when we're that close together. Take a second for both of us to laugh it off, and then get back into the action.
