Sounds reasonable to me. Guys, if you want to fuck her up the ass, let her put a strap-on up yours. Then she'll be more than receptive to you poking her brown-hole. Same goes with wanting her to swallow your cum after a blow-job...Lick the cream-pie out of her pussy after you've given her your high hard one and chances are the next time you ask her to swallow your load, she'll lick the ol' salami clean.
