Time for my step-mom to drink my cum

I go inside, and boil water in the tea pot, then as the water boils I take one of the tea cups back to my room and pour my cum from the soap dish into the tea cup. Then I quietly return to the kitchen, just in time for the tea pot has started making a whistling sound, so the water inside it is now boiling.

I leave the water to boil for a little bit longer, take out a second tea cup, tea bags, sugar, and milk from the fridge. I put the tea bags in the cups, then pour the boiling water in both, seeing strings of cum floating around in Millie's tea. It looks like quite a lot, I think to myself, then I stir it around with a spoon, trying to make it dissolve as much as possible.

I add milk and two tea spoons of sugar to Millie's tea, put a bit of milk in mine, and then I go outside with the tea.

Millie gives me a smile when she sees me come out of the patio door, then says thank you when I give her her cup. I take a seat on the sun lounger next to hers, and watch her through the corner of my eye. She has put the cup down on the small table between our sun loungers, waiting for it to cool down a little before she drinks it.

I can wait, I think to myself, so I grab the newspaper and read it, and then after about three-four minutes Millie reaches for her tea cup. She takes one sip, grimaces, then says:

"Tastes a bit sour, maybe the milk is a bit off?"

No, you are just tasting my cum, I think to myself, but out loud I say:

"Mine is fine."

Millie takes another sip of her tea. Swirls it around in her mouth a little, grimaces, but then says:

"You are right, it is fine."

Then she drinks it down in a few gulps, and thinking that I am watching my step-mom drink my cum gives me a boner, so I have to shift my legs around so that she can't see it.
