I let my stepson fuck my pussy, but he decides to fuck my butt

I gave my stepson the opportunity to enter my pussy, but he decides to penetrate my ass instead. It was completely unexpected, but also so arousing. He penetrates deeper and deeper, bringing me incredible pleasure. I moan with pleasure, feeling every movement of his cock inside me. This forbidden pleasure makes me crazy with desire and I just can't stop. We are both immersed in this forbidden act, enjoying every second of it.
