I had always been a little turned on by my sister-in-law’s lack of self care and awareness for her clothing, but this was off the charts. I had NEVER seen so much of her exposed without her even realizing. I mean, hell… her poor shorts and panties were basically playing the roll of a g-string thong now.
“There! All fueled up!” Kat said, putting the empty gas can away. “Hope on, fire this baby up, and show me the ropes!”
“Alrighty!” I replied as I stepped up onto my zero-steer lawn mower.
I sat down in the seat and reached over to the control panel on the side.
“Alright, first, you want to put the throttle all the way forward, so that the choke is on.” I explained.
“Okay, choke. Yup!” Kat exclaimed, standing on the left side of the mower and leaning over me to see my instructions. Her massive tits were right in my face.
“Now, you just want to turn the key, and when she fires up, turn the choke off.” I instructed.
“And how do I do that, exactly?” She asked in a lustful tone.
“Well, uhhh… you just pull the throttle back a little until you feel a little ‘pop’.” I explained.
“Here, let me climb on and you can watch me!” Kat suggested.
“Okay, that works!” I replied.
As I was getting ready to get up, Kat climbed up on the mower with me. I was still sitting in the seat as she stood in front of me, her insanely thick thighs and bulging manhood right in my face.
“God damn… I just want to fuck her…” I think to my self, my cock tenting my pants straight up.
“Hold on Kat, let me get up!” I said, in a playful voice.
“You stay there! How’s this work for ya?!” She exclaimed.
In on swift motion, she reached into her butt crack, pulled her shorts and panties out, slipped my shorts off cock, and sat her massive fat ass right in my lap. My cock slid riiiiight into her pudgy asshole. Kat smirked at me as I let out a big moan of pleasure.
