Tom was having more than a little fun watching a chunky beauty run around the park. Her body jiggled with every footfall, that fat continuing to shake for what seemed like minutes even after she stopped. He blushed as the girl caught him staring a few times, and she started to show off, making sure to bend over and show her huge cleavage, or shaking her ass a little more as she ran. But as she was doing this, the woman suddenly tripped, falling hard on her ass. Tom quickly ran up to her and offered to help her up. "Thanks... Ouch that really hurt... I think that's gonna leave a big bruise...Umm... I know this is really straightforward, but my butt's too big for me to look back at it... Could you come to my house and look to see if it bruised? I was thinking of wearing a really short skirt later and can't wear it with a big black and blue mark." Tom couldn't believe his luck, this beauty wanted him to check out her ass!!! He of course agreed and in no time they were at her house. The woman giggled as she pushed him onto the couch, taking off her shirt and showing a lacy cami underneath. Tom was so turned on he was getting lightheaded... Until he suddenly shrunk!!! The woman continued and soon had her pants off and lifted up her cami to show off her ass as she looked back to see Tom had disappeared! Tom jumped up and down and she luckily saw him. "Oh my gosh, look at you!!! You're tiny! What happened?" "Umm... I have no idea..." "Oh... I get it, you wanted to make real sure I didn't have a bruise anywhere on my ass, so you shrunk yourself so you could see better!!!" Before Tom could reply she quickly grabbed him and slammed him against her sweaty stinky ass cheek. "Do you see any bruising?" "Mmmrrpphhh..." "I take that as a no, but you know... I think there might be one in between my ass cheeks..." Tom screamed as the woman pulled back a cheek to show a totally shit stained crack. Unfortunately for him she was VERY thorough, and smeared him all over her crack until he was covered in her shit. "Hmm... no bruising huh? Well, I know you want to do the best for me, hell you shrunk yourself for me, so my asshole kinda hurts, you could rub it, right?" Before TOm can say no, she has his face smothered against her asshole. PPPHHHHRRRTTTT!!! "Whoops, sorry about that, but if you shrank yourself down to get closer to my butt you must have known what you were getting yourself into." SSSPPPLLLUUUUURRRSSSHHH!!! "Ooo, that was a wet one, hopefully I don't SSPPPRRRTTTT, SSPPPLLLLAAARRRTTT SPPPreeeeeennnnplopplop. Damn... happens every time I scratch my asshole." She giggled as she dropped Tom into the pile of shit she had released. "Do me a favor and clean that up hun, I'll make sure to come back for you when my ass itches again!"
