hun,
i would say this is a BIG start for things to come. i started this way as well. i have nice legs (for a girl even) and my fiance liked it when i wore a pair of sheer black thigh highs to bed. she kept caressing my legs while having oral sex. GOD, i luved that! it progressed from there. take it slow and watch for signs of her not being ok, then back off for a bit. read her feelings, and always make sure you make her feel special!
