Your sister-in-law has been b@bysitting for you since the wife's away from home and you have been working late. You go out with the boys and end up coming back so late! The scene starts with you finding your sis-in-law in the marital bed wearing your wife's lingerie! You question her a little but she looks so hot, that beside your wife has never even bothered to wear the sexy negligee you bought for her birthday! She notices that you are getting hard, your cock is growing from the excitement of having a half naked women in your bed, for once! It doesn't take much for her to lure you in and before you know it your cock is in her mouth ;) Your wife has never blown you this good mmmm you are in for a treat tonight! Your slutty cock hungry sister-in-law begs you to fuck her raw, to cheat on your wife, impregnate her! What could be more exciting than fucking your wifes sister in the marital bed ;) You give her a good hard pounding fucking her in missionary & doggy until you explode deep inside her. After she lays back in bed and teases you in a much darker tone asking you just how devastated your wife would be if she knew? Oh and she is so fucking fertile :)
