taking to flight - finished

Three verses:

she's been a dutiful daughter for long enough
she was eager and well-behaved
she was studious at school and never gruff
she was kind, if a bit too grave

I used RhymeZone.com here (gruff, grave)

there's this boy, her senior by a couple years
experienced, and so worldly-wise
when she's with him she has nothing to fear
he knows all answers when doubts arise

I checked Rhymezone again but stuck with my original ideas.

he convinced her pursuing the course of their love
his uncle has got this summer house
there's no detail that he has not thought of
just thinking of her gets him aroused

Checking Rhymezone yet again as well as my Penguin Rhyming Dictionary. Yet I found nothing useful for "house". I'm not too happy with the last line (too outspoken), but whatever...
