During our company training, we got a fellow female colleague to help us jerk off. It was a 4-on-1 session! She licked and fucked every single one of us until our balls were completely empty. Seeing her suck cock with a big smile while playfully saying 'Oh stop it~' was incredibly erotic. We were shocked by her huge tits once we got her clothes off! Our masturbation pet Mina is seriously the best colleague ever!
