As a virgin, I finally lost my virginity on the very day my father passed away. My partner was my stepmother. Until then, she had only pleasured me with her hands and mouth, but after my father's death, she finally allowed us to have sex. At first, she seemed hesitant, but the moment I inserted my large cock, she became completely obsessed, thrusting her hips wildly and tightly clenching my penis. Although she had told me not to cum inside her, I ended up ejaculating into her mouth instead.
