The ingredients for anal sex for a couple from my point of view is foreplay with an anal toy, oil but not directly near the forbidden sweet spot. Oil is good for massaging and getting into the mood. With oil comes arousal and heat. A relaxed mind is important too. Any tension of the body might cause the muscles to tense up and could be painful in my opinion and experience. The back door can close fast for me if I am not ready:)
I had an amazing live anal sex show this past weekend. The whole show can be viewed in the members area if you missed it. Here are some screen shots from my forbidden sweet spot show.
My next live chat & play is Sunday, April 19th at 8pm est. Hope to have you there!
