After Aunt Meg went back home Jack and Janet resumed their normal activities, still naked of course. And, of course, they fucked every chance they got.
A few weeks after Meg left, Janet received a call from her mother asking if she could visit. They agreed to have her visit beginning the next week.
Again, Jack worried that they wouldn’t be able to go nude and fuck but Janet reminded him that the naked rule was still in effect and it also applied to granny.
So the next Sunday at noon, Granny arrived. As with her sister when she answered the door she was naked.
“Oh my god, Janet! You’re naked!”
“I see you’re observant just like Meg.”
“Why are you naked?”
“It’s the new house rule. You’re either naked or you can’t stay. You’re welcome to stay in a hotel and we can visit there but if you want to stay here you’ll have to undress after you enter the house.”
Granny thought about it. She didn’t like to be nude in front of others. Her husband had died early, at 54 years old only a year ago. She was 55 now and by no means old. She had kept her youthful appearance.
But she didn’t want to stay in a hotel so she agreed to her daughter’s rule.
She entered the house and walked to the living room.
She wasn’t prepared to see her grandson Jack naked, but there he was on the sofa, his long cock hanging between his legs.
“Hi gran!” He said as he got up and gave her a big hug, making sure to press his cock against her.
She was a bit flustered but she had agreed to get naked so she undressed right there.
She was in very good physical condition from using the gym regularly. Her boobs sagged, but not as much as other women her age. She had just a bit of cushion on her tummy and a nice firm ass.
When she removed her panties, her salt and pepper pubic hair was thick on her pussy. She didn’t like to shave.
She was a little taken aback by her grandson naked with his hardening cock against her belly.
He let her go and she looked at her daughter and asked, “are you and Jack having sex?”
“You mean are we fucking? Hell yes we are! He’s great in bed. I’m sorry I waited this long to get him in bed.”
Jack sat next to his Granny on the sofa. He put his arm around her shoulder and pulled her close to him.
“Uh, Janet? I’m not sure I’m comfortable with this.”
“It’s okay mom, just relax and enjoy it. Jack really is an excellent lover.”
While his mom was talking to her, Jack moved his hand down and cupped a breast. He rubbed the nipple, making it hard and making his Granny moan.
“Ohhhhhh my god! I’m letting my grandson fondle my tit! What am I doing! Ohhhhhhhhhhhhh god, it feels so good and it’s been so long! God forgive me but I can’t resist!”
Having made her surrender, Jack put his other hand between her legs, making her spread them to give him access to her cunt. He ran his finger through her gash then twirled it around her clit.
“Ohhhhhhhhhh yes Jack! Ohhhhhhhhhhhhh god yes! Oh god! It feels so fucking good!”
Jack then knelt in front of Granny and started to lick her cunt.
“Ohhhhhhhhhh my god! Oh my god! Oh god Jack! It’s been so long since anyone has licked me! Ohhhhhhhhhhhhh god, it feels wonderful! Ohhhhhhhhhhhhh yes!”
Jack licked all over, concentrating on her clit.
Finally Granny begged, “oh god Jack! Fuck me! Ohhhhhhhhhhhhh god, please fuck me! I need your cock so bad!”
Jack pulled her ass to the edge of the sofa and shoved his very long and hard cock slowly into her cunt.
“Ohhhhhhhhhhh! Fuck! Fuck! Fuck! Fuck me! Oh! Oh! Ah! Oh!”
Granny moaned as Jack plowed her cunt with his cock. He twisted her nipple as he fucked her.
Janet was sitting next to her mom and was sucking on her nipple.
“Oh god Janet! What am I doing! You’re making me do the most forbidden things!”
“I know mom, and you’re loving it!”
Janet took her mom’s face in her hands and kissed her, pushing her tongue into her mouth. Her mom resisted at first but the passion overwhelmed her and she started kissing back, completely surrendering to it!
She started pushing back against Jack and feeling Janet’s tits and cunt. She put two fingers into her, then added two more.
“Oh yes mom! More! Put your fist in me!”
“God! You are a slut, Janet!” Granny said as she tucked her thumb into her palm and worked it into Janet’s cunt.
“Oh yes! Ohhhhhhhhhhhhh god mom! Fist fuck me! Ohhhhhhhhhhhhh yes!”
Janet sucked a nipple into her mouth then bit down on it.
“Ohhhhhhhhhhhhhh! Oh god! I’m cumming! Ohhhhhhhhhhhhh god yes! It’s too much! Oh my fucking god!”
Jack started to rapidly pound her with his cock until he threw his head back and howled, “oh my god! I’m cumming inside you, Granny! Oh god yes!”
“Yes baby! Cum in my cunt! Oh goddamn! Ohhhhhhhhhhhhh! Oh! Oh!”
She had stopped moving her hand in Janet’s cunt until she stopped cumming. Then she resumed, sucking on Janet’s nipples and rubbing her clit. That was all it took for Janet to orgasm!
“Ohhhhhh mom! Ohhhhhhhhhhhhh god! I’m cumming! Oh god!”
“Yes honey! Cum for me! Cum hard!”
Janet was jerking all over as she spasmed. She scissored her legs and grabbed her mom’s arm as she almost fainted from the jolts of pleasure!
Jack pulled out and the cum poured from Granny’s cunt.
When Granny pulled her fist from Janet, Janet dove between her legs and sucked all the cum from her cunt, then licked the gobs clinging to her thighs.
Janet sat next to her mom and kissed her, pushing the cum from her mouth to Granny’s.
When she pulled away, Granny said, “I can’t believe I did this. I’ve never even thought about having sex with my family! Why did you start doing this, Janet?”
“Actually it’s been building for a while. I just feel free when I’m naked and I’ve always loved fucking. Probably why I’m single now. And I know you loved it. Just like Meg did.”
“I’m not surprised. She has always been a slut like you.”
“I’ll take that as a compliment. So why don’t we see if we can get Jack hard again.”
Janet knew it wouldn’t take much to do that. She started to stroke his cock then told her mom, “Why don’t you suck his cock mom? That always gets him hard quickly.”
“I don’t know, I’ve never done that. Your dad didn’t think it was proper.”
“I’ll show you how mom. You just put his cock in your mouth. Like this.”
Janet closed her lips around Jack’s cock. Then she sat back up.
Jack looked disappointed but Janet said, “now you try it mom.”
Hesitantly her mom leaned over Jack’s cock and opened her mouth. She closed her lips on it and Janet told her, “Now lick all around his cock and make sure you use a lot of spit.”
“Ohhhhhh Gran! That feels amazing!”
“Start bobbing up and down, still using lots of spit. He likes it when you make slurping noises.”
Gran was learning fast. She really liked making Jack moan!
Janet sat back and rubbed her cunt while she watched her mom suck her son’s cock.
“Keep doing it like that. He’ll cum pretty soon if you do. When he does, swallow as much as you can. You’ll love the taste!”
Gran wasn’t sure but she kept sucking.
After several minutes, Jack moaned and the first spurt jetted into her mouth!
She almost gagged but swallowed in time to avoid it. Jack spewed several ropes of cum into her mouth and Janet told her to save some so they could kiss and swap the cum.
Jack finally stopped cumming and Gran kept some of the last spurts. She kissed her daughter and they swapped his cum, each swallowing some.
Gran laid back and after catching her breath, said “oh my god! I loved sucking your cock Jack! I love the taste. I’m just sorry I waited this long to do it!”
“Well, you can make up for lost time now, mom!”
In part 4 the 3 women will get together.
