My girl enjoys anal, but she was apprehensive about doing it with me due to my size. So I rimmed her ass real good first, relaxed her, then fingered her, moving on to a vibrator, using plenty of lube, until eventually I penetrated her with my equipment...she loved it....and we have done it many times after..just take time...when she used the strapon on me, she did the same thing, though the strapon wasn't as big as me...it took time to loosen my virgin ass up...but I agree...straight or not, nothing better than having your ass fucked, my orgasm was incredible...
