It was the grownup feast of the year in our mansion. My mom and I had the table with stacks of solid food and drink. Like before, my mom is still very pretty with her hair's-breadth, slim body and casual wearable of jacket, revealing blouse and knee-length skirt. Until now she seems very hungry at the moment before it is six o'clock. We were waiting in the drawing elbow room and there was an hour to go. We were staring boringly at the television but I was enjoying the aloud rumble of my mother's starving belly. I felt the complete hollowness in her belly as I sat up tight to her. She kissed me passionately before we fell asleep. As we woke up, we started to eat, my mom was eating and eating and drink to a greater extent than I was. As she continued, I noticed her empty slim belly was getting bigger every min. Then as there was a quarter of food left, she lay back slowly on the couch and started placing her hands on her big aching belly after she opened a few fundament buttons of her blouse to let the belly visible and cool. I came over and kissed it for her. `` Thank you, honey.'’ I said ; `` Mom, you have to finish up the rest on the table.'’ She said ; `` beloved, I love to but I will burst my belly open…'’ As she saw how defeated I am now, she suddenly changed her mind."If I eat the rest of the leftovers myself, I promise then we'll have our common soldier time.'’ I smiled and felt so eager for my mom to get her belly giving and bragging before our private prison term. I embraced her tight and she wrapped her arms around me. As she could n't get up because of her cockeyed heavy belly, I brought the leftovers to her ; she ate all the rest and drank a fully 125 litre carton of water. After that she opened her blouse completely to let her huge belly and mamilla to turn to their full size. I lay down on her and and brought my dick to her red backtalk and suck it to moisten it for me to rub it over her massive bare belly. As we kissed, then her cheek, her chest and finally all around her beautiful tumefy belly. As she continued to snog me passionately, she pulled her diffuse lips from my sass and said ;"Honey, I'm sorry, but I need the toilet."I said ; `` Mom, you promised me…'’ She started to bring in she did promise me. I said, `` Mom, if you really demand to go…'’ but she said ;"No, I'll hold it in. I'll keep my promise to you.'’ I continued kissing her belly and lay on her nipple and licked her nipples. I heard my mom moaning in pain from her bellyache and the torment of holding in her water. I then put my ear to her belly and listened ; her paunch was moaning and groaning loudly. Mom was getting more uncomfortable by the pain of holding in her urine. I gently rubbed where her extremely full bladder that is ready to burst. After an hour, my mom was fidgeting uncomfortably ; she wanted to drain her urine. She said ; `` Honey, I'm sorry again, but I'm going to erupt !'’ As I did n't want my mom to surcharge her bladder, it's time to get her debilitate. I said in concern ; `` Let's get you to the toilet.'’ My mom smiled as I agreed to help her. As she could n't get up from her hard belly, I lifted her off the sofa and towards the grand staircase to the bathroom upstairs. My mom was very laboured to carry and I took each step very slowly even though I could n't see where I was going to lay my infantry. I said in vexation ; `` I have you, mom. Just harbour it in. ‘'She said in pain ; `` Please hurry, sweetheart !'’ My mom was still groaning in pain in the ass to have got it in as I finally reached the top of the stairs and hurried to the bathroom. As I turned the node on the bathroom door, it won't subject. I said in affright ; `` It's locked !'’ My mom looked surprise as she realised something. She said ; `` I remembered I left the key downstairs by the backdoor.'’ I said ; `` I must get it ! I'll leave you here.'’ I slowly lay her on the base outside the bathroom door. She was now near to the second of exploding her bladder. She said in ache ; `` Please be immediate, honey !'’ I kissed her on the impudence. I said ; `` I'll be right hand back.'’ I darted to the stairs and slid down the banister. My mom started rolling onto her side of meat on the floor with her expression turning a bit red. As I reached the back door, I saw a diminished heap of keys with tags on them. I rushed through the atomic pile, with ones saying `` front door, back door and garage door. While my mom was groaning horribly loud in despairing distress, I could see her from where I was. Finally, I found the key, grabbed it, ran back and up the stairs and arrived where my mom was. She now was boiling red in the face and sweating heavily and rolling on the floor with her skinny bare legs crossed together, but she was glad that I was back. She wailed ; `` Please rush, mantrap !'’ I finally unlocked the can door and opened it. I quickly lifted mom up again and placed her on the privy. I placed my hand under her annulus to remove her knickerbockers from her haired vagina. She held me tight for backup and ease before she started to pee. She sighed in relax and litres of her urine drained. She looked at me proudly and said `` thank you'’ before she kissed and embraced me on her fluid publicise thigh and I buried my head into her large tits and suckled her pap .
