Artwork that features characters with plump and sensuous thighs is no rare occurence on pixiv. In fact, you'll find them quite easily thanks to the helpful tag 魅惑のふともも (miryoku no futomomo; lit: bewitching thighs), a fitting tag as the thighs you'll see will certainly hypnotize.
The pose Mei Yoneme (from Love Live! Super Star!!) is striking definitely showcases her lovely thighs, doesn't it?
Do you have any of the thighs below running through your mind?
