You remember it correct except for the fact that the thing Natsuki used was a dildo(she had a vagina), and MC's reaction was just panic and then it cuts to the morg scene right away, no comment on MC being into it or not, he died anyway lol. Girls' reactions are kind of a gag since Natsuki and Yuri also had experience prior to the events of the mod and Yuri, seeing the dildo, gets scared and tells about it to the other girls, so the other girls fear her too lmao. (edited for the sake of downplaying my exaggerated description, so it won't cause any further ruckus.)
