The Up the Middle sex position is that final stroke of analingus genius before going to town on an increasingly worked up bottom.
To get into this position, both partners should be on hands and knees. A wider stance for the receiver will make things that much better. The giving partner can also add hands and sex toys to the mix. That said, this is another sex position that’s just begging to have playmates swap at half time. We all know that versatility is key to a healthy sex life!
