In a threesome, when a man and a woman are having sex, vaginal or anal, and the third persos, m or f, licks the cock and pussy, or cock and ass, of the first two.
That was the best sex I've ever had, getting my cock licked as it was sliding in and out of her, the fucklicking was awesome.
You: “my dog just died.”
Me “I’m sorry...”
You: “my sister was holding her, and...”
Me: “and what?!”
You: “and they both got run over by a bus and died.”
Me: “that’s a total fucklebutt!”
