I work at a local park doing maintenance and repairs and I have discovered that lots of women in their early 40s come here to exercise in the mornings presumably after they have dropped their kids at school. For the last few weeks between 9-11am I have particularly noticed one woman she is about 40, long dark hair usually tied in a ponytail, curvy body stuffed into activewear and big sunglasses. I live in the southern hemisphere and summer is coming so I've been working either with my shirt off or just a singlet. She smiles and says hi every morning and she has caught me staring at her ass a few times as she walks by.

Now things have been heating up last week, on Monday as she approached and I was doing my usual stare she asked if I'd like a blow job. We disappeared into some bushy areas and she sucked me off keeping her sunglasses on the whole time till I came and she swallowed the lot.
The next 2 days were the same then I didnt see her for the rest of the week.

This week she was back and again we disappeared off while she was sucking me she asked if I wanted to cum inside her and I nodded. We fucked for about 30sec and I blew my load in her. She pulled up her yoga pants and jogged off.
I'm finding myself having feeling for her now. I know she's married, she wears a ring and she never takes off her sunglasses. I want to ask for her number but I'm afraid I won't see her again. What should I do?
