Without getting into too many details, I’m a service submissive, so I’m actually quite happy to be invited over to help around the house, but that needs to be something discussed before it happens! I don’t mean it’s a transactional situation, but we need to discuss parameters, limits, and other specifics long before that starts.
I was dating someone for a while where several of our dates in a row involved me assembling furniture for them, but they’d also cook (or buy) dinner, catch up with each other, etc. They and their husband had only recently moved into their home, so every time I helped them with something, it made the place more comfortable for all of us for future visits. (And since some of it was pet furniture, I got to make some very lovely kitties happy.)
The “specialty” furniture was an added bonus, of course!
