Perhaps this chap actually just fapped, and then decided to ejaculate inside her? Hence her already being covered due to it not well...Flowing into such a small hole, and him having already ejaculated, justifying him to not continue.
This case is closed boys, he is not trying to kill her.
all you have to do is rub the penis against her no need to penetrate and when you ejaculate hold it against her pussy as much as possible or use a straw to make sure it gets in her
