Mary had put her meetings with Sophie on hold until both her children had gone off to university. Fortunately she was still able to meet Mark for her twice weekly sex sessions and she still managed to fit in the odd masturbation session at home when she was alone.
Her 18 year old son Rob had finished school and was off to university in September and her daughter Michelle was due back from university in a weeks time.
One morning Mary was on her way out to play badminton. She had just got to the end of the road when she really needed the toilet so she quickly drove home again. As she walked to the toilet she heard her son Rob talking to someone. She knew he was still in bed so wondered who it was. His bedroom door was slightly open and as she looked in she saw her son lying naked on his bed with a pair of panties round his erect cock and him holding another pair to his nose.
He was saying, 'oh Michelle I can smell your cunt juices, I love them and want to lick you.'
He was wanking furiously and Mary was mesmerised as she watched her son wank and cum into his sister's panties. Not only that but Mary felt herself getting aroused.
She waited until he had cum and burst in and said, 'whatever would your sister say if she knew what you were doing. Give them to me and I'll wash them before she gets home.'
What Rob didn't tell his mum was that his sister had given them to him to wank into.
Mary knew her son wanked but never expected to catch him like that. She took the panties, went downstairs and threw them into the washing machine to wash later. She went to the bathroom and headed off to play badminton.
She saw Sophie there and told her what she had seen. She was fascinated and wanted to know how big he was and how much cum he had spurted. All this talk was soon arousing Mary and she decided to masturbate when she got home. She remembered the soiled panties in the washing machine and went and took them out and went into the bathroom and locked the door.
She took her panties off, picked up a pair of panties and sniffed them. She could smell her daughter's cunt juices on them. She put a hand between her legs and felt how wet she was. She started playing with herself as she sniffed the panties.
Then she took the other pair and was amazed how much cum there was in them. She knew she wouldn't be able to resist and licked some cum off them. She loved the taste as she swirled it around her mouth. She was frantically fingering herself and licked the remaining cum off them and soon had an enormous climax with her mouth full of her son's cum.
Later that afternoon Rob came home and sat chatting to his mum. She said, 'you really need to keep your door closed if you're going to do that.'
'Yes, OK, but you're the only one who's going to see me,' he replied.
'Your sister is home from uni at the weekend,' Mary said.
'OK, I'll be careful, but I need sexual relief,' he replied.
Mary said, 'I realise that, how often do you do it?'
'Every morning and at least one other time during the day,' he replied.
Mary asked, 'what about today?'
'Just the once so far but I feel the need for another now. Do you want to watch me?' he asked.
In her head she knew she wanted to but also knew it was wrong. But sometimes the need is overpowering and this was one of those times.
'I'm going up to my room, why not follow me,' he said.
Rob went upstairs and Mary waited a couple of minutes. She knew it was wrong, but couldn't stop herself and was soon on her way upstairs. She loosened a button her blouse on the way. She was already feeling aroused as she walked into his room. He was lying on the bed naked, his cock semi hard.
She sat on the edge of the bed and he took her hand and put it on his cock. She very gently started rubbing it, not wanking, just stroking but in no time it was rock hard and she loved the feel of it.
It was arousing Mary as it bought back memories of years ago when she was his age and started wanking her older brother. Now she was doing it to her son.
She started wanking properly and could tell by the look on his face how much he was enjoying it. She felt a little precum oozing out and she pushed his foreskin back over the head and rubbed the precum into the head. Rob loved this and told his mum not to stop. As more precum seeped out she rubbed it all into the red cok head. She knew he wasn't going to last much longer and carried on wanking furiously and suddenly spunk was spurting all over his body. She got a lot on her hand and while he wiped himself clean with a tissue she licked the cum off her hand. She loved the taste and texture as she swirled it round her mouth before swallowing it all.
'How was that,' she asked.
'Wonderful, hopefully we can do it again soon,' he replied.
Mary was really horny and went into the bathroom and masturbated while thinking about what she had just done.
Later in the evening as they all watched the television when his dad went out of the room he said to his mum, 'you know what I'm going to do in the morning, when dad goes to work why don't you come and see me.'
Mary replied, 'I need to think about that.'
But in reality Mary knew she wouldn't be able to resist.
Mary had a restless night and kept thinking about Rob. She knew what she was doing was wrong but the urge was overpowering. She had breakfast with her husband while still wearing her dressing gown. She kissed him goodbye and as she heard his car drive away she went up to her son's bedroom.
As she neared his room she loosened the belt on her dressing gown. She knocked on his door and he said, 'come in.'
He was lying on his bed naked with his cock standing to attention. She was happy to wank him but she preferred to fuck him or suck him. That way she would get some pleasure for herself.
She sat beside him on the bed and started playing with his balls.
'I want you to wank me, mum,' he said.
