Vicki has always been pretty upfront with her naughty past. Sometimes going into great detail and sometimes, because of embarrassment, not really telling me everything. 

One thing she told me a few years ago surprised me. Vicki came from a big family and has several brothers and sisters of all ages.

Her sister Mary is about 3 years older than her and looks completely different. Vicki being tall and blond but her sister Mary being smaller with dark hair.

Vicki's clubbing days started when she was old enough for Mary to take with her. I got the distinct impression that this is where Vicki got all her slutty traits from when they went clubbing together. 

I can imagine Mary taking Vicki along as a bit of young eye candy to attract the older guys. I bet Vicki got all the tips on how to play the game from Mary.

Anyway, years on. Mary had married a guy called John who was about 10 to 15 years older than her. He had his own business and liked to splash the cash on whatever he liked. 

Mary was definitely a big influence on how Vicki perceived how the relationship arrangement worked with men. Basically if you see a guy that can give you a nice easy life, make sure he gets everything he desires in the bedroom department. 

I know for a fact that Mary made sure she sucked his cock every day. Letting him empty his balls into her mouth even before he got up in the morning. To be fair, what guy won't say no? he seen her as a keeper, but Mary was only looking after her own interests.

Vicki told me when she was in her early twenties, Mary and John invited her to join them for a few days on holiday. They'd hired a villa for a month, and it had a spare bedroom if she wanted to come out for a week or so. 

Vicki didn't really think anything of it, but sure Mary might want some company at some point. She was sure John wouldn't mind having two bikini-clad girls sitting by the pool to look at.

Vicki didn't want to intrude too much, and some days just went down to the beach. Knowing Vicki, she probably wanted to meet some local guy for some holiday no-strings-attached fucking. 

She also said she went out at night to do her own thing. Giving Mary and John some time together.

She'd heard them fucking a few times and was pretty embarrassed hearing her sister loudly moaning while being fucked.

She was surprised how loud Mary moaned and assumed John must have a big cock and was a good fuck.

Vicki used to get in really late from being out clubbing, almost when the sun was coming up. She didn't go into any details on who the local Spanish guy might have been or if he'd fucked her on the beach.

This is the part of the story I'm surprised Vicki told me about and swore me to secrecy.

It was one of those mornings she'd gotten back pretty late.

It was almost noon and she'd been sleeping for a couple of hours. She heard her bedroom door opening and turned around to see John standing in just a towel. She hadn't really noticed before due to the kind of swim shorts he wore, but she could see John was pretty big; even soft.

It looked much bigger than anything she'd ever encountered. No wonder she'd heard her sister moaning so much. 

John told her that Mary had planned to take her shopping but had left her sleeping because she'd got in late. Mary had decided to go into town without her and would be back in a couple of hours. 

Vicki told me she was only wearing a little baby doll nightdress and panties and was lying on top of the bed due of the heat.

She instinctively pulled the sheet up to cover herself, but she also couldn't stop looking at John's huge cock just covered by a towel. 

Remember, Mary was 3 years older than Vicki, and her husband John was 10 to 15 years older than her. With Vicki in her twenties, that would have put John between 35 and 40 at the time.

He'd have had a lot more life experiences than any of them and was and is a pretty confident guy.

He walked over to the side of the bed as he'd obviously seen her checking him out. He dropped the towel and asked if she liked what she saw.

She said she was still a little tipsy and drowsy and didn't say anything but felt herself biting her lip.

His cock was definitely the biggest she'd ever seen, both in length and in thickness. She openly told me when telling the story it was much bigger than mine. 

John told her she could touch it if she wanted. She blushed but found herself putting her hand out to feel it, rapping her thin fingers around her brother in-law's thick cock. 

She told me she felt it instantly begin to stiffen as John let out a gentle moan, telling Vicki to stroke it. She knew it was wrong but she couldn't help herself. She was mesmerised by her brother in law's huge cock. 

Vicki looked up at him shyly knowing the situation unfolding was wrong but she couldn't help herself. 

Vicki was almost half his age and had never thought about him sexually before. Her sister Mary had told her that John was well endowed. She'd laughed it off thinking her sister was just bragging.

Now John was standing by her bed, her hand now stroking his thickening cock. Her hand looked tiny with her fingers wrapped around his shaft as she gently stroked it. John moaning lightly at Vicki's touch.

His cock now fully hard, she said he must have been at least 9 inches long and very thick. 

She bit her lip again, wondering what was about to happen. John took any doubt she had away when he told Vicki to suck it.

Before she could change her mind, she closed her eyes and leant forward and took his huge cock tip into her tiny mouth.

She began to suck on him as she heard John moan with pleasure. Her mouth already watering with excitement, she took more and more of it into her mouth as her saliva lubed his gorgeous cock.

Vicki had never sucked a guy this old before, but she'd also never sucked a cock so big before. 

She'd already lost control of the situation and was now sucking John's cock enthusiastically. 

She felt his hand on the back of her head as he encouraged her to take it deeper into her mouth. She could feel his cock hitting the back of her throat, but he was expertly fucking her mouth without making her gag.

Holding it in place just long enough before letting Vicki breath. 

This is something Vicki has enjoyed for years, and I know I enjoy doing it to her. I just didn't think until now that it might have been John that made Vicki like it so much. 

She must have been only sucking it for a few minutes but could taste dribbles of pre-cum running down her throat.

She admitted that this excited her as I've said before, Vicki likes to please her men.

Even if it is her sister's husband.

John must have known if Vicki carried on for much longer he was going to blow his load down her throat. Even though he'd probably had Mary swallow a load a few hours earlier.

John pulled Vicki's mouth off his now wet, throbbing cock. Vicki looked surprised as she was eager and willing to swallow John's cum.

He pushed her back onto her bed, her little lacy panties already wet with excitement. John moved forward and ripped them off, breaking the tiny strings holding them on.

He held them to his face, smelling Vicki's sweet wet sex.

He didn't need any further proof. Vicki was going to let him fuck her.

As he leant down she opened her legs spreading herself from him. He lowered his head and as she closed her eyes, as she saw his head disappear between her legs.

Vicki always has herself well-trimmed when going on holiday and back then she'd only have the tiniest strip of hair if not bald.

She felt his mouth cup her wet pussy lips and gently began to suck on them. Driving her wild with lust when he probed his tongue deep inside her slit. Running it slowly up and down, giving her clit a little suck every time. 

She now knew another reason why girls liked older experienced men.

He had her writhing around on the bed as he sucked and licked at her pussy. It didn't take long for his expert tongue to bring Vicki to orgasm. She was holding the back of his head as she bucked uncontrollably as she climaxed.

Grinding her pussy against John's mouth. Only coming down from the sensation after several orgasms. 

John looked up from between her legs and she blushed when she saw her wet sex all over his face. He smiled, knowing she'd enjoyed him licking her to orgasm. 

She knew he wasn't finished with her as he lifted himself up. Pulling her little nighty over her head and admiring her fit young body.

Vicki knew it was wrong and could never tell her sister, but she was desperate to feel his massive cock inside her.

John smiled, he already knew she wanted it. Her legs were spread wide open, offering herself to him.

He even teased her by making her ask for it, no beg for it. 

Vicki embarrassingly blurted it out, "Yes, yes John... I want your big cock inside me." 

He'd placed the tip of his cock just at the entrance of Vicki's wet pussy lips. As he slowly pushed it inside her, she felt her pussy stretch open Making her gasp as she felt his thickness for the first time. 

He gently eased his massive cock into her tight young hole. Letting her adjust to each thick inch before pushing further into her.

It was driving her wild with lust, the slowness of his movement and the anticipation of having him drive further and deeper into her pussy.

She could feel every inch of his veiny thick cock. 

Even though she was soaking wet, she was surprised how easy she was taking him inside her. 

John had obviously fucked many a tight pussy before and knew how to give maximum pleasure from it.

He began to push in faster and harder as Vicki's pussy got use to his girth and length.

She felt as if she were in a dream as she felt him thrust his thick cock into her over and over again.

She knew it wouldn't be long before John was ready to cum, but she knew didn't want him cumming while fucking her in the missionary position.

She'd already lost all respect for herself by then when she asked, no, pleaded for him to take her from behind.

John slowly pulled out of Vicki's pussy, her wet sex coating his glistening cock.

She smiled as she rolled onto her belly and felt John pull her onto her knees. Vicki spread herself wide open, clearly offering John her body to use for his pleasure.

She felt John's presence behind her, and then the tip of his cock pushed her tight little hole wide open again.

She gasped out loud as she felt his cock slide into her wet pussy once more. It felt even deeper than before as he began to thrust his cock harder into her willing cunt.

Holding her tiny waist and pulling Vicki onto his throbbing cock.

Ramming it into her over and over again, making her cry out with sheer pleasure.

She'd have let John fuck her like this as long as he wanted.

His cock was driving her wild.

All of a sudden John grunted as she felt his semen fill her pussy. She felt her insides being sprayed with his cum as his cock jerked and twitched, pumping his seed inside her. 

She unashamedly cried out for him to fill her pussy with cum.

She wasn't worried, as she always took precautions when going on holiday.

John slowed a little but didn't pull out until he'd emptied himself into her, his wife's sister.

As they tidied themselves up John did admit that he'd always wanted to fuck his wife's little sister.

The two of them knew it would never be mentioned again, even in jest.

Vicki knew she'd been far too much of a slut to ever bring it up again.

Since telling me the story years ago, I'd always wondered if Vicki ever fantasized about having John's cock again. 

She certainly has a few toys that are as big, and maybe she got me to buy them for her so she could imagine being fucked by his massive cock again.

Who knows?

We still see them for normal family stuff but I almost feel like I'm cucked again.

Even though it was years ago, I know John has fucked Vicki but it secretly excites me.
