This is less of a post and more of a pointer to an animated gif on tumblr. It features a vigorous pegging and a woman clearly enjoying herself. That’s a description that could be applied to a million similar tumblr animations, but what caught my eye here was her expression just after he orgasms. It’s a great half smile – partly rueful, partly amused and with a hint of ‘Now look what you’ve done!’
I reblogged this to my tumblr to make sure it sticks around, but I found it via the Pegging with a Smile site (which has a magnified version).
