My brother was never much of a womanizer, but somehow he managed to land a beautiful wife! However, my sister-in-law comes to me with a problem: they're both so inexperienced that they can't seem to get the baby-making right. "Maybe it's because I'm bad at sex..." she worries, and then she drops a bombshell—she wants me to be her practice partner! Before I can even process the idea of doing that with my brother's wife, this beautiful woman starts attacking my cock with everything she's learned from the internet! "I'll never tell my husband..." she whispers, and my self-control completely collapses. Since it's "baby-making practice," raw insertion is a given! Far from being bad at it, she's incredibly erotic, and as she works hard in cowgirl position, my balls are ready for breeding! Because this practice is just like the real thing, a raw creampie is inevitable! Hey, sister-in-law... this is way beyond practice. What are you going to do if you actually get pregnant from this!?
