Louise Kay looks very hot. Not what I would say is my usual type but I would love the experience.
I agree with Anth's earlier comment that I haven't really noticed much difference with bj's but DFK is nice with a piercing. Also pierced nipples do give me the horn as its just a little bit kinky which makes a change from real life.
Not sure about DFK. I've only met one girl who has a tongue piercing and does DFK and I find that my toungue is a bit sore afterwards, I'm wondering if it's probably a bit sharp. Very enjoyable though, especially the BJ!
