First-timer doggie-style fuck-fest with close mate results in chick orgasm

I've been besties with my stepbro for years, but our relationship never crossed the line... until now. Our very first-ever time, we kept things professional at first, but when he pushed my buttons, I whipped out a shriek that shook the house. The force of our connection made me spray for the very first-ever time, a super-naughty experience I won't forget.
