If they ask you will have to tell them at some point, especially if they are near the ages of 9 or 10. If it's too embarrassing you could say to them something along the lines of 'Your Mummy and Daddy loves each other very much and from time to time we play a little game. Unfortunately it's only for adults'. For younger kids I would just put them to bed.
If there's any consolation, I remember one of my cousins when we were both around the age of 12 & 10, told me in person when I visited her house she once caught her parents having sex one night. It came up as part of a discussion on adults we made at the time where we shared some of our most awkward or funny experiences growing up. She wasn't shy or awkward about it, but just told me the facts as is. I told nobody else about it however.
Has only happened to my wife and I once so far... We were having sex in the morning since our 4 year old wasn't awake yet. He woke up and came into our room to ask for help turning the TV on. We're nudists so we're often nude, so that wasn't a surprise for him. He didn't ask what we were doing either. I did have my wife turn on his cartoons though since I didn't want to waltz out to the living room with an erection. Luckily, once paw patrol is on and he had an apple sauce packet, he was sufficiently distracted so we could continue on.
Hi Kids sorry, I’m sorry you saw that. Can I take you back to bed? Perfect just give me a moment to put on some clothes.
And then answer honestly any follow up questions.
Well I would guess the 17 yr old would certainly know, the younger boys 8 and 5 not sure what we would do. Likely not say much of anything as doubt they would question it.
I'd probably not notice.

"Your mom & dad are idiots for not locking the door... we're building a door, under the covers by the way."
The answer depends upon their age at the time, but always just open and honest about the fact that we were having sex. How you describe it depends upon their age.
if they just saw stuff under the covers you could say you're playing a game but if they saw everything you'd have to tell them some mild version of the truth ("when mommies and daddies love each other very much...")
I'd probably be to focused on what I was feeling to notice but if I did, it would be really awkward.
Has happened before. They don't question what was going on and we just tell them to get out
Do you ever witness them processing what they saw?
If I had kids? Mommy and daddy were just wrestling.
I'd tell them the truth.
Why would you tell them anything but the truth?
If they were too young to understand that it's not appropriate to mimic themselves?
You don’t have to lie to children, ever. Especially in order to teach them that they’re not old enough to participate in the full human experience.
With my then-wife, pour young kids walked in on us a few times, before they learned that they don't come in when the bedroom door is closed, at least without knocking first. We didn't make a big deal about it and simply told them that mommy and daddy are having some special alone time.
Given kids are 2yr old and 1 yr old I wouldn't tell them anything, just put them back to bed
Nothing to explain. I'd just ask them to be busy with something - I'll have time for them in half an hour or so.
If they have questions later... I'll have age-suitable answers.
If there are no questions - then it's ok anyway.
It's happened to me. I'm was just honest about it and explained what we were doing and why and that's it's normal for grown ups. I don't want them to make a thing of it.
what kind of thing do you mean here?
Were you concerned about them no understanding there's things adults do that aren't appropriate for kids?
No, they know some things are for grown ups. Like knives, medication, alcohol etc.
"Mommy and daddy are just playing a fun game of Twister"
the truth they are smarter than you think
Explain to them what sex is.
Hide the sausage game.
