Stacy's Mom 10 - A Breeding Stud for Mothers and Daughters

My girlfriend Stacy Gardner is away at college, but we've been maintaining a long distance relationship. That means so long as Stacy is a long distance away, her hot mom has been riding me like a rodeo bull. Don't worry, Stacy knows, and so long as whatever I do is under her mom's supervision, she is okay with it.Lately, Stacy's mom has been peddling me to her MILF friends, including an old family friend who I've always called "Aunt Sandy." No! We're not related! But that didn't make it any less weird when Sandy paid me to knock her up. Apparently my sperm is so fertile that it is becoming a hot commodity among the wannabe moms of the neighborhood. I'm fine impregnating hot middle aged women, but when Stacy and her mom surprise me with a special request of their own I am caught by surprise. Am I really going to impregnate my girlfriend and her mom?This 9,000+ word story is romantic erotica about an intensely erotic triangle where an older woman and her daughter share a younger man. It includes a kinky threesome, supervised impregnation, and a horny hump session with a family friend. It is explicit and intended for adults only.
