What would you do?

One night, you are snuggled in bed with your lover and your lover wraps their hand around your cock. You get hard because of their slow jerking. Feels awesome and you’re well on the way to cumming in your lovers hand but your lover falls asleep?
This has happened a few times and I’ve wondered what others would do.

What would you do?

a - Be thankful for what they have done?

b - Finish yourself off?

c - Something else? Like what?
