I love the idea of the look myself! I have no problem inching those panties down, carefully undoing the garter straps, and reattaching them as the panties are pullled down below them. Adds to the foreplay.
Though I have to say, the idea of side tie panties is great! Grants access to the succulent pussy or throbbing cock underneath very quickly yet still looking the sexy best before hand! Yummy!
hands down or up, side tie panties wins.
