Who could resist that ass? : Part 2

Note : This story is completely fictional!

 For the next few days after Billy and Becky’s wild sex romp in the game room things were very tense around the household. Right after their first fuck Becky went to make dinner and when they sat down to eat Becky would not look at or talk to Billy. After dinner Becky said she was tired and went to her room. Billy did not know what to think because she even said he could keep her panties and he figured that meant they would be going at it every chance they got. For the following three days Billy came home from school to an empty house and wondered where his mom was. Becky was going to a local gym and staying there late working out, tanning, and get rub downs to calm her nerves. She would come home late, just before her husband came home so she would not be alone with Billy. Becky seemed to feel ashamed of what had happened between her and her son. Finally, four days later Billy came home and Becky was preparing dinner. Billy walked in the front door and into the kitchen where he saw his mom bent over pulling some pots out of the lower cupboard. Becky was wearing cut off jean shorts and Billy stopped in his tracks to get a good look at the ass he had his face buried in four long days ago.

Becky stood up and caught him peeking at her ass and just turned away and continued with dinner. Becky said “you hungry? I’m making pasta tonight” “sounds good mom” Billy replied. Billy went in the living room and turned on the t.v to watch espn. Becky came in the room sat down on the opposite end of the couch and said “Billy, we need to talk” Billy looked at her and said “sure mom, what’s up”. Becky grabbed the remote and turned off the t.v. Becky put her hands on her face then looked at her son and began said “Billy, what we did was so wrong on so many levels. I feel so ashamed of what happened between us. I can’t believe I cheated on my husband with my own son. I can’t believe I did something like that, I feel so horrible”. Billy looked at the sadness in his mother’s eyes and said “it’s o.k mom I don’t think of you any different and what happened between us will stay between us”. Tears began to flow down Becky’s cheeks as she said “I know baby, it has to stay between us and we can never ever do anything like that again o.k?” Becky pulled her son in for a hug and Billy said “yes mom, I understand” as he could feel his dick getting hard in his jeans. Becky stood up and said “o.k I’m glad we talked, I have to make dinner” Billy smiled and said “I’m glad too mom”, but what Billy was really smiling about was hard nipples that were poking through his mom’s t-shirt. Becky walked out of the living room and Billy, like always watched her sweet ass as she walked away. Billy thought to himself “shit, that sucks oh well I still have her panties” and he went up stairs and jerked off with her panties in his face like he had done every night since their mom son fuck fest.

Later that night at dinner Billy’s dad announced that he was assigned a very high profile case and would be out of town for the weekend. Billy looked at his mom and could not help but smile to himself and think what might happen with mom and son with the house to themselves for a whole weekend. The next day Billy drove his dad to the airport and saw him off. Billy’s dad looked at him and said “you look after your mother while I’m gone” Billy said “yup, sure thing dad”. Billy then jumped in the car and sped home. Billy figured his mom would not let anything happen between them again, but he still enjoyed spying on her and jerking of later with his prized possession, his mom’s thong.

Billy got home and searched to house for his mom and didn’t see her anywhere. He went up to the game room and didn’t see her there. He looked out the window and there he saw his mother forty-one year old mother lying by the pool in her beach chair wearing a yellow bikini. Billy felt his dick get hard immediately as his mom flipped over on her stomach to get some sun on her back. Becky reached back and untied her bikini top to reduce to tan lines on her back. Becky’s bottom was a thong and her lotion covered cheeks had Billy hypnotised. Billy ran in to his room changed into his swim trunks and headed out to the pool to join his mom. As he walked out the door his mom gave him a little smile and asked “going for a swim?” “yeah, could use a couple laps” Billy replied. Billy jumped in the pool began swimming lengths of the pool, stopping at the end of the pool to look at his mom lying by the pool. Becky then reached back and tied up her top and walked over to the edge of the pool, got in and swam under water towards Billy. She came up right beside him at the edge of the pool and smiling she said “let’s go, there and back once. I think I can still take ya. Loser cooks dinner.” Billy smiled and said “alright ready...set” Becky took off swimming as fast as she could Billy started right behind her and was gaining on her. At the turn Billy had almost caught her and as they kicked off the wall to come back Billy was starting to pull ahead.

Becky knew she was going to lose so she reached over and grabbed her son’s swim trunks almost pulling them off. Becky then started to pull away but Billy reached and grabbed her thong pulling them completely off. Becky raced to the end of pool turned to Billy and smiled “looks like I won”. Billy held up his mom’s yellow thong began spinning it on his finger and said “looks like I won”. Becky swam at Billy and tried to grab her bottoms from him. They wrestled in the water playfully groping each other as they did. Finally, Billy held his mom against the edge of the pool and kissed her. Their tongues flicked each other as they moaned in each other’s mouth. Billy reached down and cupped his mom’s ass, Becky reached around put her hands in her son’s swim trunks and grabbed his cheeks as Billy grinded his dick into Beck’s pussy. They broke the kiss both breathing heavily. Becky then opened her eyes and pushed Billy away and said “stop, I told you no more, we must stop” and she grabbed her bottoms put them on and got out of the pool she looked back and said “you’re still making dinner”.
Billy spent most of the next day in his room watching t.v and jerking off with his mom’s panties.

It was late in the afternoon and Billy thought about jerking off in his mom’s panties again instead he heard a knock at his door. Becky walked in and said “I almost forgot, give me my thong back.” Billy handed it to her and she said “maybe now you can forget and get over what happened. It’s not going to happen again so don’t bother trying again”. Becky walked out of the room and Billy watched as she walked out wearing his favourite faded blue jeans. Billy laid in bed thinking to himself “one minute she’s pissed off at me, the next she’s flirting with me like wants to fuck my brains out. What the fuck is going on?” He decided a good work out would relieve some stress so he got up and put on his work out gear to go for a run. As he went down stairs he passes his mom who was at the sink doing dishes. Billy put on his headphones and turned to tell his mom he would be back in a bit and caught his mom looking at his butt. Becky smiled at him and continued with the dishes. Billy shook his head and went out for a run. He worked up a pretty good sweat and did some thinking about what to about his smoking hot mom before returning home just before dark.

Billy walked through the front door kicked off his running shoes at the door and took off his sweaty socks and went downstairs to the laundry room. When he made his way down to the laundry room he saw his mother bent over taking clothes out of the dryer. Billy took it all in as his mom’s ass stared back at him. Billy peeled his sweat covered shirt off and walked in the room. Becky turned and was a bit startled and said “oh you scared me” as she looked at her son’s rock hard abs. Billy said to his mother “mom can you wash these I want to go workout again later” as he handed her his socks and t-shirt. Becky took them and opened up the washer and started to load it with dirty clothes. Billy then took of his gym shorts and said to Becky “mom, could you wash these too?” Becky turned around and saw her son holding out his gym shorts with his fat eight inch cock dangling between his legs. Becky’s legs went weak and looked as though she was going to faint. Billy reached out and hugged his mom holding her tightly. Becky pushed Billy back and looked down at his rock hard abs and big hanging dick between his legs. Becky kept her eyes on Billy’s dick.
