My boyfriend believes I'm at ease, unaware of his intimate act

I've been seeing my boyfriend for a while now, and he's got this kinky side to him that I absolutely love. He's always sneaking around, recording us during our most intimate moments. He's got this collection of videos that he keeps hidden away, and I'm completely okay with it. I know he gets off watching me, and I kind of get off on the idea too. His latest addition to the collection is a steamy session we had last night. He caught me by surprise, filming me from behind as I was riding him. The sight of his thick cock disappearing into my culo grande was enough to make me moan in pleasure. As he fucked me harder, I could see his excitement growing. And when he finally came, he made sure to capture every moment of it. I love being his puta, and I can't wait to see what other naughty things he has in store for our next session.
