I thought he pulled a stool out and did a little trick, then did it again.

I saw it as

1. Stick figure in bed
2. Blowjob
3. Piledriver
4. Rest
5. Blowjob
6. Resume piledriver

I thought it was funny when i first saw it. I see the whole car thing now after reading the comment. So maybe the stick figure never leaves his house and just gets blowjobs. They could be a sex worker that takes money for letting other stick figures suck their stick. And they are waiting for their next client in-between. Or the stick figure in the first frame is the one giving blowjobs and waiting.

I saw it as:

• Sitting on bed alone
• Lying in bed with partner
• Sitting on the cuck stool next to the bed

I like that better, it’s canon now
