First collaboration in the series with “Hai●”! Yui-chan, a beautiful big-breasted loli girl, uses the hypnosis technique to transfer this sensation to the toilet bowl, and cums while licking the toilet bowl! In addition, she loves peeing in white wine, which she purrs and drinks as if bathing in it. Yui-chan can't refuse no matter what is asked of her, such as ``licking the toilet bowl'', ``drinking tongue'', ``drinking urine'', and ``swallowing cum''.
