Have her lick your balls. That always feels nice. Make sure she keeps things moving; Have her suck your cock and then go down and lick your balls, while she keeps you going with her hand, and switch. Also, it feels really nice when they grab your ass while they suck your dick.

I have personally always wanted to face**** a girl. That would be hot. I would be gentle, though.

I remember my first blowjob, and she was inexperienced too. My penis is really sensitive, too.
