He slowly removed my undies, bent his head buried between my thighs

It was with my first boyfriend and also the first time I got naked in front of him at his apartment.
We both got excited after seeing our naked bodies. I knelt and held his big shaft and slowly caressed and took it between my lips
He told me that he felt the warmth of my lips began to push slowly, but he came quickly filling my mouth; it was amazing for both of us.
