Caught off guard, I challenged my aunt to a video game match, thinking I'd win easily. But she had her own plans. Wearing a short miniskirt and a tight top, she teased me with her long blonde hair and perfect, fat ass. As we played, she'd lean over, giving me a clear view of her white girl panties. I started to lose focus, and she took advantage, winning round after round. With a sly smile, she reminded me of our bet - a blowjob if I lost. My cock throbbed as she knelt down, her big ass sticking out, and took me in her mouth, deep and bareback.
