She's cool together with you cumming inside her, which is a pretty big deal.
It's great to have intercourse, but it's even better when you can just let it all 
out and also have a great orgasm. Maybe it is a secure day, or maybe she's on birth control, but either way she's down by 
it. All you value is that you were able to give her all of your sperm,
like you were trying to create a baby. We all know 
how it is when you're within the zone and it's really hard to grab!
