The first time you have a finger in your ass, it feels like you have a finger in your ass. An Encyclopedia states that "the inner third of the anal canal is less sensitive to touch than the outer two-thirds, but is more sensitive to pressure" and that "the rectum is a curved tube about eight or nine inches long and has the capacity, like the anus, to expand". Those who enjoy either role may be referred to as versatile. I find that I can have stronger orgasms while being penetrated anally, but these are clitoral or vaginal orgasms, not anal orgasms—those are quite elusive.
These could be breasts. My young lover can't seem to fuck me enough because of it. That's just fine with me since I've had a sexual reawakening since my divorce 10 years ago.
Who is she?
