She gives a blowjob to a guy she just met at the park and he cums in her mouth.

She didn't know how to go talk to that guy who was there alone.

She already knew what she wanted, but didn't know how to get it.

There was only one thing on her mind, going home without giving a blowjob is out of the

question.

So, she went to the guy to bring up the subject with him and be able to propose.
