Step-Aunt Risks It All

You've been staying with your Step-Aunt and Step-Uncle while you have been waiting for the lease to go through on your new apartment. Your Step-Uncle is working away this weekend and you decide to take your Step-Aunt out for dinner to say thankyou. She tells you that you really don't need to do that, she has loved having you here and it's been nice to have some company seeing as your Step-Uncle always seems to be working away.
During the meal, the two of you have flirty banter and your undeniable connection means that even the waitress thinks that you are a couple!
When the two of you get home all giggly, your Step-Aunt confides in you that she thinks your Step-Uncle might be cheating on her. She has lost her spark, and for all of the things she has done for you you decide that you could be the one to revive her again. You pull her in for a kiss, shocked and reluctant at first your Step-Aunt can't resist but to give into temptation. It's so wrong, she knows she shouldn't cheat on her husband in general let alone with her Step-Nephew. But she admits you make her feel like the most amazing, beautiful Woman in the world and you can do the things to her that your Step-Uncle can't. She wants to feel you, raw, bare inside of her - even more risky that she isn't on any contraception. You will need to be careful. But the closer she gets to orgasm she begs for the two of you to cum together, she is done caring about how stupidly risky this is and there is nothing she wants more than to feel your forbidden seed inside of her. You empty the biggest load you have ever done inside of your Step-Aunt, she keeps you inside of her whilst the two of you cuddle together. She hasn't felt this special in a very long time, you have bought back her spark and she is determined to leave your Step-Uncle for good so that the two of you can live happily ever after.
