I will become your post-workout relief toy

Hi! This is my first time posting on the bulletin. I hope I'm doing this properly. Don't be afraid to comment any questions!

Scenario:

You are a tall, slightly muscular woman, somewhere in your 20s, who has been attending the local gym quite frequently. You give off an air of confidence that makes it easy for you to make friends, but there is one person that has intrigued you not too long ago: a small boy (my character) that's maybe of your age or maybe a bit younger. While he's diligent with his routine, he's still a bit on the skinny side; once you overheard his trainer mentioning he's not too interested in building muscle. Either way, you can't help but tease him whenever you can just for how cute his reactions can be. Sometimes you'd wink or blow kisses at him, other times you'd make your grunts a little more suggestive when he was around. Every time he'd look away, doing his best to hide the blush on his face.

You were hoping he would eventually muster the courage to open up a little more and get to know him better, but one day you got tired of waiting. Switching to more intense exercises might have helped with that decision. You just happen to spot him getting ready to leave, so you start to think of ways on how to approach him. Whatever you come up with, you're resolute on making him yours.
