Easy - a thong. Don’t care the cut or style. Don’t care if simple every day kind of stuff or fancy.
Love the aesthetic of looking down and seeing a beautiful female body in a thong giving me a BJ. Similarly, love the aesthetic of a thumb looped around the thong, pulling it to the side with my hands on both ass cheeks in doggy.
Perfect way to accentuate a beautiful part of a woman’s body.
