Just one??? I've got a billion of 'em. Try reading a sex guide or a romance novel every now and then for inspiration. Don't learn from porn.
My all time favorite had to be giving cunniligus with her standing in front of a full length mirror and making her watch

. I would sit down indian style with my legs outside her feet licking up and grip her butt to support. Watch out because she's likely to fall when she reaches orgasm.
Other fun things to try.....
-hold her arms back doing it doggy.
-open or close her legs to make her tighter or looser.
-rub a knuckle on her @$$ when giving cunnilingus.
-lick your thumb and rub her clit when she rides you.
-pick her up every now and again and have her hold on tight and grind you while you walk around the room. You can also put her against a wall.
-anything like a pullup bar or stair case she can hold on too standig up
-try treach her g spot with your tongue. 69 or face riding works better.
-leave her socks on and she'l get there quicker.
-if you spank her butt cheeks from the bottom edge up and in you can cause her to tighten for a sec or two. If you spank from the top you can topple her balance.
-use a clitoral vibrator during sex or bjs. You can use an internal egg but don't go deep or your bang the egg against her cervix.
-if you cause her cervix pain by going too deep or she just needs to come to relax her ovaries, do it doggy with her leaning way down.
-pillows help a lot with misionary positions and lying rear entry.
