Daniella had already been my girlfriend for about 6 months in those days.
We often had sex in that time, and the position we loved to make at most was "69" oral sex, where I lie with my back on the bed, and she lies above me, while I'm licking her pussy.
I thought to myself how I can tell her what I really like to do with her.
I was attracted to her very much, and I really liked her to use my mouth as her toilet.
I knew that most of the people are disgusted of just thinking about it, and I was afraid she would be very disgusted of me and would break up with me.
I thought about it for a few days, how I can tell it to her without she taking it too hard, and finally I got to a genius idea – I will tell her nothing!
Instead of telling it to her – I will try to gradually make it happen naturally!
I thought to myself – how can I create a gradual process which will end when she uses my mouth as a toilet?
I decided on my first step – next time we make "69" oral sex, I will "accidentally" lick her asshole, hoping she would like the feeling of the "accident".
About 2 days later, at night, I was waiting for her in the bed, while she took a shower.
She then finished her shower and came to the bedroom.
She got on the bed and we immediately started making out. I got lied on my back and asked her to come above me, to be in "69" pose, so I can lick her pussy.
She got on me and I started licking her pussy while she has a great pleasure.
I thought to myself - "This is the time to act like I planned".
While licking her pussy, I started to move my tongue more and more up, towards her asshole.
I finally started feeling her hole with my tongue and started licking it hardly.
She suddenly asked me "What are you licking there?"
I got stressed. What should I answer her?
I didn't answer.
She again asked me "Where are you licking me? Are you licking my ass?"
I then answered with no confidence "I think so..."
"Do you like it?" I asked her?
She said "Yes!! Wow! I really like this feeling! I will move my asshole towards you mouth".
She then moved her pussy away from my face, and instead pushed her asshole into my mouth.
I licked her asshole intensively for a few minutes until she got orgasm.
She really liked it when I licked her asshole, and starting from that day, almost each time when she came out of the shower and we started making sex, I licked her asshole.
This was the first step in the gradual process I wanted to make.
From that day, after she took a shower, licking her asshole was something we were doing naturally.
After about a month, I thought it's time for the next step – licking her asshole even if she did not take a shower before.
It means that if she used the toilet after the last time she took a shower, her asshole will not be totally clean. But I've already licked her asshole many times, so I hoped she would let it happen.
So a few days later, after we got back home from work, I started making out with her and we finally went to the bed.
I again started licking her pussy while she lies above me in "69" pose.
For licking her asshole after a shower, I did not need to fake an accident as I did in the first time I licked her asshole.
But at this time, the last time she took a shower was the night before, and I remembered that at the morning of this day she used the toilet for a long time.
She would probably not let me lick her asshole in such a situation.
So again, I started to move my tongue upper towards her asshole, until I finally got it.
I licked her asshole intensively.
She said nothing!
I could smell and even feel with my tongue, that her asshole is not as clean as when I do it to her after she takes a shower. But I liked it!
She was enjoying while I was licking her asshole, and she did not pay attention to the shower issue.
Then after a few minutes she got orgasm.
She then said "but I didn't take a shower!".
I answered, lying to her "Who cares? I did not feel any difference in smell or taste!".
She thought to herself for a second and answered "Wow! So it means we can do it without me taking a shower before?".
I answered "Yes!".
So, starting from that day, there were many times we had sex and I licked her asshole, when it was not after her taking a shower.
A few months later, I again was waiting to her in the bed, while I knew she is using the toilet and that she is taking a shit.
A few minutes later, she came to the room.
I told her: "Baby, I really like to lick you asshole right now!".
She said: "Baby, this is so cute, but I just returned from the toilet, and you know....".
I answered her: "I don't care! I lick your asshole many times without you taking a shower before, so why does it matter if you used the toilet a few hours before or a few minutes before?".
She said "But, it might be smelling bad..".
I answered, lying "You asshole never smells bad. I like the smell and taste of it very much and always. Come on, get on my face, I really like to make you feel good! ".
She hesitated for a second, but she was probably already very horny from our talk, and she could not stop herself from coming to sit on my face.
