For me it would depend on the female and situation to be honest. But, if she is cool, I would probably hang out and help. Kids aren't easy, and if a lady carries your baby, it's the least you can do. But, in the end it's all up to her.
She is telling you without telling you. All women fantasize about a MMf. Two men sucking on their tits at the same time. Start with the dirty talk and dildos. Go slow at her speed. Watch that cock get hard when she finally admits it.
