The party was in full swing, but the real action was happening beneath the table. I'd caught my friend's husband's eye earlier, the spark of our shared secret igniting a fire between us. Now, as I knelt before him, his cock in my hand, I could feel his excitement growing. I worked him slowly, my palm sliding along his shaft, his breathing hitching. He tried to stay still, to not draw attention, but his body betrayed him, his hips moving, his cock throbbing. I could feel his orgasm building, his cock twitching, his cum pulsing into my hand, a secret birthday gift just for me.
