Don't ask... Just make suggestions about what you would do, what turns you on, what you like, etc. You'll get feedback from there, and find out what they do or don't like, as well. Always throw comments and suggestions around, and get them horny and excited about the ideas. Should flow pretty naturally, like any conversation. They might say something - then you'll make a sexual comment about it. Like if they're going to take a shower - as part of an innocent conversation - you might suggest to join in. IE, "we might have to do that together". Always throw in those sexual inneundos, tell them what you would do, make it sound amazing, be smooth about it, and let the tension build - even if you're not going to have sex at that moment. Sometimes its even better to get them horny and intrigued, and leave them wanting it even more.
Never had much deflection on their part this way... They were always up for most of anything, 'cause they're wild and horny, too... Always adding things in there, like wanting to be choked or spanked, or whatever.
Generally, they'll get an idea of what you want by the things you say and do, and the body parts you are focusing on, and what you want to do with them... But always make it sound appealing.
You can also do this while IN the act - as they're already aroused, more willing to get crazy, not as deflective, etc.
But never ask - STATE your desires and what you would do with confidence. Be bold about it. The topic should be sexual already, too. Or at least, redirected that way. The sexual banter and arousal you create JUST before the act itself... Getting them into the mood, and all that.
If they're against your ideas - and some have very strict boundaries - at least you'll know, and won't have to waste time. Some girls are COMPLETELY against any kind of ass play whatsoever, and will make this known pretty quickly... Even if you never bring it up.
