When I got on a crowded bus wearing a mini skirt, the cock of the office worker behind me pressed against my ass. I felt it getting harder and bigger, and I felt uneasy. I noticed that my skirt was lifted up by the erect cock, exposing my ass, and my panties got wet with embarrassment and excitement. I couldn't resist, and the man's hands started to grope my ass and breasts, and I tried desperately to suppress my voice. He pulled my panties down and inserted his hard cock right there, and when I was pounded so hard that I trembled and gave way, the erect cock in front of me also entered my mouth.
