[F][M] Short and sweet, my first anal

A few years back, I was working at a hotel in my home country, Mexico. I had met my then boyfriend (now husband) in Europe, and he came to visit me and my country. One night, we went to a cuban bar, danced salsa while drinking way too many mojitos. I got quite drunk, and got super horny.
We headed back to his hotel and started fucking. We started with missionary, then I rode him, and he started fucking me doggystyle. He had already tickled my butt while grabbing my ass during missionary, but now that my ass was up in the air, I got this desire to try something new… so asked him “do you wanna try from behind?” He didn’t understand at first because technically he was already from behind, but finally got it.
He lubed his dick and my ass, pressed the tip onto my butthole, I remember taking a deep breath while he was pushing it inside. The tip hurt a little, but then it got in super easily, really smooth, to my surprise. He fucked me like that for a little while then I started to feel he was about to come. And just when I felt the spasms in his dick, pulsing warm cum in my ass, I got the strongest orgasm of my life…
