A big dicked man secretly has sex with his friend's sister in her bedroom, using various positions and sizes

I sneak into my friend\'s sister\'s room, and we quickly get down to business. She\'s a hot, petite blonde with a tight little pussy. We start off with doggystyle, then move to cowgirl as she rides my big, BBC-like dick. It\'s a wild ride, but we\'re just getting started.
