This is Pt. 2 of Gramps Enlightenment. It can be read as a standalone but to get the context I would recommend reading Pt. 1
As Patsy pulled into the car parking area at the services, looking around for a suitable place to park, one of the phones in the centre console started to ring, strangely enough, Nicky and Patsy had the same ringtone, same phones just different cases.
'Can you get that......? If it is dad tell him I will call back in 5 minutes, I need a wee first!'
It's OK, it's mine. Nicky answers the phone 'Hi Sharon, give me a minute mum is just parking the car so I am watching one side of the car as there is so much stuff in here we can't see properly..... Bloody Sian has taken literally everything she owns!!'
Patsy looks at Nicky and mouths (I need a wee, lock the car and come find us) she jumps out, looks around, and heads off towards the building across the car park.
Meanwhile, Nicky gets out and stretches 'What's up Shazz?'
'Any chance you will be fit enough for the competition next week? With Sian, Michelle, and 3 others scooting off to Uni we are pretty light on capable competitors.'
'Umm, I have an appointment with the PT on Tuesday, but I am still a bit restricted on movement in my hip..... Maybe it'll be OK but I am not making any guarantees.'
'Bugger..... OK well pop over and see me after PT anyway I have something to tell you that is better in person.'
As she is talking she notices her gramps looking slightly flushed as he gets out of the car, and as Sian dives back inside the car she can't help but notice his slight head tilt and smile as he gazes longingly at Sian's bum.
Sian climbs back out of the car, grabs James's hand, and pulls him towards the building 'Come on gramps, you can treat me to a lolly...... I need something to suck and an ice lolly will be perfect' she snuggles into his side and leans up to kiss his cheek, making her skirt ride up. Nicky is shocked as she is sure she caught sight of the fact Sian has no panties on.
Nicky being a suspicious girl opens the backdoor of the car and notices the towel wadded up on the floor, picks it up, and is surprised to find it slightly damp, bringing it to her nose the aroma is unmistakable.
'I see mum has inherited grammas need for the loo as soon as we stop anywhere.' James mutters as Sian snuggles in close.
'Yeah dad is always moaning about it'
'Oh well, I need to rearrange myself' he winks at Sian as he heads towards the gents 'Meet back here and we will see if we can find her after.'
As Nicky wanders into the building her mum is just coming out of the ladies so takes the keys for the car 'I think we will just stretch our legs and get a bottle of pop or ice cream, then we can get back underway........ Is gramps still in the toilet?'
'I don't know Sian, gramps and Michelle wandered over whilst I was on the phone..... Is Sian in the loo?'
'Yeah, she and Michelle were giggling by the driers just now.'
'OK, I need a wee so I will see you in the shop in a minute.'
Heading into the toilets Nicky sees Sian and Michelle applying lip gloss at the mirrors so marches up and growls at Sian 'I want a word with you'........ Dragging her further into the toilets and finding an empty cubicle she pushes her little sister in and squeezes in before shutting the door. Michelle stands open-mouthed and watches.
Lifting the bottom of Sian's skirt Nicky confirms her suspicions about the no panties.
'What are you doing?'
'Testing a theory and I or in fact, Michelle was right, gramps is hot for some sweet pussy.'
'Michelle?...... what has she to do with you not wearing knickers?'
'Chill, haven't you noticed everything is so much more relaxed since gramma died?........ We can pop in to see gramps without having to be fully buttoned up in a straitjacket?....... Don't tell me you haven't seen him looking!!'
'What!!!...... This is gramps...... '
'Yeah, a fit youngish guy with a cock that needs some loving.'
'No.... he is probably outside now telling mum what a stupid little idiot you are.'
'I don't think so after he has just let me suck his cock and then fucked me!!!!'
'You are lying...... he wouldn't.'
'You are just jealous because he has fucked me and not you......... Anyway, how do you know I had no knickers on?'
'I saw you lean up to kiss his cheek and saw your bare ass......... I then found the towel.'
'There is your proof then......... he wants me!'
'It isn't fair.'
'You chose to ride up front with mum......... see what you are missing!'
'I am gonna tell mum!'
'Don't be fucking stupid......... just think when you drive back tonight mum is bound to go to sleep, she always does when we are out at night..... It is like her eyes need to shut after dark...... let her go in the back and when she is asleep start talking to gramps, slide your hand into his lap..... See if you can get his cock hard......... That is if I haven't fucked him dry first....... Now let me out.' Sian smirks and cups her own pussy and breast to show Nicky she is braless as well.
Nicky lets her sister out and then pulls her panties down to pee, suddenly realising how wet her panty gusset is....... Sliding her fingers through her pubic hair she finds her clit is quite sensitive and her fingers glide effortlessly into her pussy........ Oh my god she thinks, I want some of gramps's cock as well............ At least on the next bit, it is Michelle sitting on gramps's lap so there will be nothing to worry about.
Sian quickly fills Michelle in as to what has happened........ Michelle looks slightly worried 'I will grab some panties and pop them on before we get in the car then and sit in the same place as I was before.'
'Well if you don't want some cock I do!........ Plus if we change the plans now mum and gramps will know there is something wrong........ Just tell gramps if you don't want him to touch you and you can just sit up prim and proper on his knees.'
Everyone gets ice cream and a drink and head back to the car....... Nicky holds Sian back slightly by pretending she needs to show her something on her phone before they get going again 'Will you ask gramps if he wants to fuck me as well?'
'Oh trust me, he will love it when he sees your furry pussy and won't be able to resist....... I think he has realised gramma was a prude.'
They both grin....... 'OK, mum my turn to drive....... Maybe, 2 hours and then stop for dinner.' Nicky chirps.
