Tonight's the night this bisexual sub learns the art of cock sucking, and their femdom trainer is eager to begin. The sub, blindfolded and bound, is led to a chair, where they're made to feel the throbbing reality of their first cock - a strapped-on dildo on the domme's dominant form. The sub's mouth is guided, their lips and tongue learning the contours of the silicone shaft. The domme's voice, firm yet encouraging, coaches the sub through each movement, from licking and sucking to taking the cock deep into their throat. As the sub's skills improve, the domme introduces a real cock, the sub's eager mouth ready to please, marking a significant step in their bisexual journey.
