Or circumstances can lead to completely forgetting about condoms at all. Some years ago Mary had some issues and had to stop taking the pill for a bit while the doc tried to figure it out.
Anyways she a business trip coming up, no real plans to play with others so she has no brought condoms along. She was visiting another location of her company.
They arranged to have one of their security staff drive her around (to and from airport, to and from offices each day). Nice young black man. They hit it off, not sexual hear really, just got along well.
The 2nd to last day waiting at this intersection where a couple of multi-lane very busy roads met a tractor trailer truck hit a car that had run a red light. Like a scene out of a movie, the car was smashed towards them at the end it somehow managed to go just airborne enough to clear their hood and changed direction enough that it did not land on the cabin of their car. Thankfully nobody in any vehicle was killed but the cars passenger was pretty hurt.
Even with the wait to give info to the police by time they got to the hotel they were still a bit shook up. Mary especially. He walked her back to hotel room. Inside room she felt she really needed a hug (nothing sexual going on in her head). So they hugged, she even cried for a minute, she told me she had no idea how it happened. Suddenly they were kissing, she had no rational thoughts going and completely forgot about a condom or that she was off birth control...that is until as she was cumming hard again she felt him throb and the warmth of his cum inside her.
Now we did not do not have any sort of fantasy about her getting pregnant by another. And part of her mind did panic , but another part was telling her she had needed comfort and release and this she had both.
A nervous couple of weeks followed, but thankfully no pregnancy.
