Louise Smithson, aged fifty-three, had a dilemma. She wanted to continue fucking her nineteen-year-old house guest, Calvin Nelson, but her husband and her son had both mentioned their suspicions and her son had almost caught Louise leaving Calvin's room the day before.
The frequent fucks had been going on since the day that Calvin arrived ten days previously, but now, with only four days left of his stay, Louise was having doubts about the wisdom of continuing.
Her husband, Tony, was at work most days but her son, Chris, was an ever-present in the house when Calvin had been fucking Louise, and it was getting caught by Chris that concerned Louise the most.
Chris had not been suspicious until his dad had mentioned that Louise and Calvin frequently 'disappeared' at the same time, but now he was almost convinced that there was something going on between his mother and his friend from University. He was unsure how he felt about it, possibly jealous because his mother was a very curvy, good-looking woman.
Chris hah had a few girls, but what he really wanted was a woman—one just like his mother.
The atmosphere at breakfast was a bit strained, not least because Louise had refused Tony sex the night before. The main reason that she turned down his advances was that he wanted to take her from behind but she could not afford for her husband to see her bare arse because it still bore evidence of the whipping that Calvin had given it when he and Louise went for a walk in the woods.
Tony went to work and, as usual, Chris got onto his laptop. Calvin frequently went to his room to listen to music, and he did so again now. Chris wondered how long it would be before Louise absented herself, but she stayed in the living room for quite a while, before announcing that she was going upstairs to do some stuff.
Chris decided that he had to know, one way or the other if his mother was getting fucked by the house guest, but he waited a while before going to investigate.
Louise went to Calvin's room, and soon they were both naked, and Louise was riding Calvin's cock.
Chris crept up the stairs, and reached the top just as he heard his mother announcing that she was 'fucking cumming.'
Chris went to Calvin's room, and in pushing the door open, he got a view of his mother's bare arse and Calvin's cock inside her cunt.
"I fucking knew it," said Chris.
"Oh shit, Chris, baby," said a startled Louise, who hurriedly dismounted, leaving Calvin's erection standing proud.
"How long have you been fucking each other?" said Chris, who seemed close to tears.
"Please don't tell your dad," pleaded Louise, grabbing her son.
"Get your hands off me, you whore," said Chris, pushing his mother away, but in doing so putting a hand on one of her large tits.
"Baby, baby please let me explain," said Louise, following her son out of the room, and not concerned at all about her nakedness.
Chris went into his room, with his mum following. Chris was now crying. Louise pulled him towards her and hugged him, and Chris found his right hand going to his mother's arse.
Chris was rapidly getting an erection, as he held his naked mother's body close to his fully clothed one.
"It is alright, baby, honestly it is," said Louise, who then kissed Chris on his lips.
Louise could feel Chris's stiff penis against her naked body, and she understood.
"Mum, how could you?" said the loudly sobbing Chris.
"It just happened. You won't tell your father, will you?" replied Louise, still holding her son tight.
"I don't know, mum, I am so confused," sobbed Chris.
"Let's sit on your bed, and talk things through," said Louise, fully aware that she was naked.
They sat, and Louise took her son's head in her hands and planted another kiss on his lips. This time, Chris responded, and they snogged. Chris's left hand went to his mother's right tit, and he massaged it.
"Are you thinking what I am thinking?" said Louise, looking deep into her son's eyes.
"I,...I don't know," stuttered Chris.
"Well, I am naked but you still have your clothes on," continued Louise.
"Mum, are you suggesting that you and I, um...,?" said a confused and turned on Chris.
"Fuck, if you want to," responded Louise.
"But, but, it would be so wrong," replied Chris.
"It would be beautiful," said Louise, removing her son's T-shirt.
"But what about Calvin?" said Chris.
"He will understand, I am sure," said Louise, unzipping Chris's jeans.
