My girl is not on pill so it's a massive stress relief !
Also you double your potential partners (i'm bi top).
It feels so kinky to stretch wide such a little hole!
And man, the best part is the gaping view ! I'll never get tired of that ! So sexy !
It also takes the "dirtiest" part of a woman and turns it into something permissible and even desirable, so after anal, nothing is off limits. That's also why I like ass to mouth, or seeing a guy enthusiastically rim me or want to even fist me.
I love the taboo nature of anal sex. That it breaks the traditional norms of sex. It's viewed as "dirty" and "wrong" and yet feels so amazing!
I love the combination of intense pleasure and some pain.
I love seeing her ass wink after being stretched open
I love the smells and sounds
I love feeling her ring twitch and flex when she cums
I love cumming deep inside her pipe and watching my cum dribble out, or get uncontrollably farted out
I love helping her get cleaned out before
I love the look on her face when I slide into her for the first time, watching her realize that some pain can feel good
I love seeing her hole the next day after a good vigorous anal session
As a plus: Not taking birth control pills makes me feel better physically and I save money haha, I also feel more sexual desire and guys tend to go crazy when a girl wants anal sex so it is also a plus to see how I turn them on even more.
