Listen here Trainer-chama! You can do many things to your Umas during her career, like going on dates, holding each other's hands, and even sloppily making out without a care in the world. However, you must never engage in steamy, sweaty, clinging onto one another like slugs, bareback sex with her during her career. Now, I'm not saying you and your Uma shouldn't fuck eachother's brains out to blow off stress, I am simply asking you to use protection. What would happen if your Uma got knocked up by you in the middle of her career? Have you seen any pregnant Umas on the tracks? Of course, you haven't. Pregnant Uma belongs at home being taken care of. Think about how happy your Uma will be when she finds out she has your baby inside her stomach. Now think about the disappointment she will feel learning she can no longer race in that condition. She will be crying on your shoulder, asking you to hold her tightly and never to let go after hearing such heartbreaking news. All that hard work and training will go down the drain all because you drained your balls inside your Uma, isn't that just tragic? You might think you can pull out but its not that easy, not only would you have need wit to fight off your own desires to creampie your Uma but you also need to be able to break out of her leglock with your strength and have enough guts to resist her sweet voice begging you to make her a foal factory. You never stood a chance against an Uma. Maybe we need to castrate the trainers... just kidding! What is done is done, you can't cry over spilled milk, or in this case its your cum. The only thing you can do should you find yourself looking at your pregnant Uma, is to marry her and raise your children together. Maybe this time because the Uma you are training is your daughter, you wouldn't think about shooting a fat rope into her tummy during her career again! Good thing I am a human so I don't have to worry about this happening to me haha!
