You would play either my daughter, niece, or cousin who had a baby about 6 months ago with a man no longer in the picture. You're staying with me and my wife while raising the kid. With you being around and nursing a lot I've noticed how much bigger your boobs are and I start feeling attracted to you. One day my wife takes the baby out shopping to give you a break and you take the opportunity to pump milk using a machine. It's then I incidentally find you and spy on your. From there we could either go in 1 or a few directions

1) You notice me spying on you and while disgusted at first, you're pent up sexual energy leads us to have a minor sexual encounter

2) You notice me spying on you and you instead pretend not to and start to tease me hoping I will pounce on you

3) You don't notice me and it's a slow burn of me low-key flirting until you eventually decide to fuck me

4) I can't contain my lust for you and I force myself into you over and over until you fully sumbit to me.

If interested, DM me with ASL and your kinks/limits
