Staying over at my girlfriend's house, I get seduced by my best friend, Rika Mariri. For two days, she whispers in my ear, dominating me with her strict, sadistic attitude. Yet her demeanor is sweet and gentle, smiling as she says, "You poor thing," while scolding me. Whenever she moves away slightly, she secretly touches my cock up close, whispering lewd words like, "You've been waiting for this, haven't you?" We sneakily have sex right next to her sleeping girlfriend, trying not to get caught. This is the story of those two intense days.
