Stepaunt's unwanted advance on me: Should I let her go further?

Stepaunts unwanted advance on me, and I'm torn between stopping her or letting her go further. As a mature woman, I know what I want. After some kissing, she eagerly pleasures me orally, leading to intense sex.

In a moment of weakness, I found myself succumbing to my stepaunt's unwelcome advances. As we sat on the couch, her hands roamed freely over my body, her lips trailing after. At first, I tried to push her away, but as she continued to kiss me passionately, I found myself lost in the moment. She took me to the bedroom, where she proceeded to pleasure me with her mouth, her tongue exploring every inch of my most intimate area. I found myself reciprocating, tasting her sweet nectar as well. As the intensity grew, she climbed on top of me, straddling me, and we engaged in a steamy session of face sitting and fucking. Despite the guilt and the potential consequences, I couldn't help but enjoy the unexpected encounter with my stepaunt.
