You pop over to see your friend your greatef by his step-mom who you have always fancied. She let's you in and you sit with her and wait for your friend to come home. She starts to flirt with you and you open up about liking the older woman. She is quick to jump on that and flirts even more and offers herself to you. You obviously accept you have always wanted to fuck her and now you have the opportunity. You manage to finish just before your best mate comes home.
