Today is training day for XL Girl Kat Bailey. She's put through her boob-bouncing paces in the park, doing running in place, jumping jacks, and calisthenics. Looking fine and foxy in her halter top and stretchy yoga pants, Kat's big tits keep falling out. After her "road-work," Kat is brought inside to work on stretching and other techniques. "When I'm done with you, you'll be able to do backbends," her trainer gloats. "You mean like this" Kat replies, getting one up on him by assuming the position on the floor. Very impressive. She notices in that position that he's got a tent-pole and it's her fault. She reaches for it and starts pulling it. This girl does not yank anyone's chain. Now that the feeling is mutual, the trainer puts her in a kneeling position and rubs down Kat's big boobs in an extra-curricular training session. That leads to Kat taking his boner down her throat and, boy, is she excellent at blow jobs.
