Cynthia Isn't Real, But I Am!

I was deeply focused on dominating a challenging stage when my step-relative caught my attention. She was chattering about something trivial until she mentioned Cynthia, my personal toy - then I decided to pay attention. As it turns out, she perceives herself as a 'hip' step-relative.
I must admit, when she requested a demonstration on how I utilize Cynthia, that was rather intriguing. She appeared captivated as I put Cynthia onto my erect member. She offered to lend a hand and skillfully manipulated Cynthia up and down.
Her gaze was unwavering, creating a slightly awkward atmosphere, prompting me to politely inquire if she desired to sample my member. Without hesitation, my step-relative eagerly agreed and eagerly engaged in pleasuring me. Straddling me, she tantalizingly teased me with her generously sized breasts, repeatedly striking my face.
This ignited my desire, leading to her guiding my rock-hard member into her moist intimacy. Without delay, I raised her attire and engaged in passionate lovemaking from behind - her divine posterior was truly mesmerizing! Allowing me to take the lead, her ample bosom bounced vigorously as I penetrated her mature intimacy until I climaxed inside her. Following our intimate encounter, she requested that I dispose of Cynthia once we were finished.
I thought she was meant to be a 'trendy' step-relative? Oh well, the challenging stage awaits my conquest.
