Note to those who answered "Call the cops". The question only asks what would we do if he was tied up on our bed at our house. That leaves it open to suggestion we knew he was there!

For all we know, we could pass a stranger in the street who says: "By the way: I tied up some random boy on your bed".
But seriously, if it was a case of actually coming home to find you there, when I didn't expect you, I would do the following (or pretty close to it).
1: Duck. The person who tied you there might be behind me.
2. SWAT the whole place. Make sure there are no other univited guests. If anyone I actually expect to be there is home, I might ask them if they've seen or heard anything strange today.
3. Question you. Only after I know what is going on, and know you, a bit better can the fun begin.
4. Tickle torture. I'm an expert at that; so Rae informs me.
5. Judging from your previous comment, it seems you might prefer to be at the mercy of girls rather than guys. In which case, I would've found this out in (3). I would also have found out how intense you like it. Then I would call the relevant girl to come get you. If you prefer guys, refer to 4.
6. Help the relevant girl load you into the boot of her car. Presumably girl takes you to her home and puts you on her bed. Now you are back to the start and you can read a response from a girl now
