Naked supper

Its getting late and all that yard has made me hungry. I figure since my mother in law took care of me earlier, i could repay her by cooking supper. I ask her what she wants to eat and she suggests grilled hamburgers and i ask me if im "up" for grilling naked with a sly grin on her face. I say "yes maam, its the least i could do for you taking care of me earlier" i go outside, still bare ass with my penis swinging and gather up my clothes and start the grill. When i come back in she tells me to take my clothes to the laundry room so she can wash them. After taking my clothes to the laundry room i go into the kitchen and start preparing the food. I take the meat outside and start grilling. While facing the grill im startled when i hear a loud smack and fill a sharp pain on my bare butt cheek! My mother in law says "you sure do know how to handle your meat"! By now she has had several beers. I say "yes maam i do" and before i realize it i also say " i bet you know how to handle my meat too". After a short silence she says " we'll just have to find out after supper won't we" then she reaches out and squeezes my ass. By this point i am so horny that im not thinking clearly so i say " yes maam". She then goes back inside and tells me to let her know when supper is ready. As soon as i get done cooking i let her know. Wr sit down and eat. When we're finished eating she gives me instructions she says " go wash the dishes, then take a shower. When you're done showering go to my room and stay just as you are, butt naked" i say " yes maam". When im done showering i do just as im told and walk to her room butt naked. My penis, now rock hard from the anticipation, is bouncing around as i walk in to see her sitting on her bed still fully clothed, but holding a belt. Im a little surprised to see the belt. She says " you've been bad today, prancing around naked in front of your poor old mother in law, i think its time for your punishment" i say "im sorry, you're right i do need to be punished" she tells me to face the wall and lean over. "Yes maam" i do as im told, spreading my legs. She swings the belt and cracks me right on the ass. I yelp with pain and jerk forward making my penis and balls flop up and jiggle. She follows that first swat with thirty more just as hard. My bare butt is now as red as an apple. When shes done she tells me to turn around. When i turn around she gets down on her knees and grabs my rock hard penis and starts to stroke it. After a few stroked, she takes the full length of it in her mouth and starts to suck and rub her tongue over the head. I was already on edge beforehand so when she grabs my freshly whipped ass i lose it, and feel her mouth with cum. She then takes me out of her mouth and finishes jerking me off onto her face. After we both get cleaned up, we promise not to ever say anything and i go to bed. Still butt naked.
