You don't have to worry about hurting Tatiana. She's a tough girl.
She's not tender-headed, either. Nothing makes her squeal like getting her pigtails tugged on during sex. "I get off on a little bit of pain with sex. I think hair-pulling is so hot."
Bite her. Spank her.
She likes anything that's a little bit rough and playful. "If a guy bites my neck and smacks my ass till it's red I will moan and purr and my pussy will drip like a leaky water faucet."
To get things started, eat her pussy like you're in a pie-eating contest.
Lick it, straight-up porno style. Go crazy. Don't hold back. Tatiana can take it.
