To fully appreciate the storyline and characters I recommend reading the three previous parts. Also, if you aren't into consensual wife sharing you might be better off reading something you like rather than this woeful tale of a couple who happily indulge their fantasies.
I had intended to finish the story off in 4 chapters but, as with many stories, it has grown as I wrote it and to give it the ending that I wanted, I have added one more.
**************************
Ben pulled his wife back down to him as she attempted to get up off the crumpled bedcovers.
"You don't want to do it again, surely?" Abi groaned softly giving in without a struggle and laying back against his muscled chest, "You'll make me sore."
"No, I just want to hold you for a little bit longer. Is that a problem?"
"Well, I'm certainly not going to object to it." she stated with a cheeky grin and snuggled against him so they were spooning on their bed.
The pair were upstairs in their bedroom having just made passionate love after Ben's brother had gone home following his afternoon tryst with Abigail.
Laying silently next to his wife he reflected on everything she had done over the week-end. Knowing how his wife had taken his brother's virginity on the Saturday and was now educating him in the pleasures of sex was turning him even more than he had ever thought possible.
"It's going well with Nathan obviously." Her husband enquired casually his fingers caressing her small firm breasts.
She sighed, enjoying the touch of his hands on her body "Yeah, it's all pretty good. He won't embarrass himself with girls when he goes to university, that's for sure."
"You're assuming he can find himself a girlfriend."
Abi looked at him with a bemused expression "And why wouldn't he? He's a good-looking lad with a very large cock. He'll make some girl very happy."
Her husband grinned "If you say so. I can't say I've ever looked at it."
"Well, he has. You can take it from me." She giggled naughtily.
"He won't get a girlfriend if you wear the poor sod out over the next two weeks though." Ben laughed, "Then he won't be any use to anyone. No matter how big it is."
"I'll try my best not to but he's very demanding." She chuckled, joining in with the joke.
"Don't forget about Frank. You need to leave some for him." Her husband ruined her good mood and reminded her about their odious neighbour's stated intention to fuck her.
Pushing herself up onto her arm she looked back at him "No, I haven't forgotten. The disgusting pig will get what he deserves. That's what you want, isn't it?"
"Yes, you know that's what I want."
Abi sighed resignedly knowing Frank would want to have her at some point. Apart from the fact that she knew her husband wanted to watch her being fucked she was now completely aware that she wouldn't be able to refuse him for very long.
"So, who's idea was Monday and Wednesday?" Ben changed the subject back his brother.
"Nathan said he wanted me again tomorrow so I suggested stopping by at your parents for an hour after work and then Wednesday... well I have to admit that was mostly my idea." she told him honestly.
With that final comment a naked Abigail slipped out of bed and, picking up her clothes, she started to get dressed continuing "But now I need to go and get our dinner prepared."
"Fair enough, I'll need my strength if I'm going to have any chance to keep up with your demands on my body." He grinned, laying back on the bed and watching his wife.
"Hmmmm... yeah right." She laughed pulling on her shorts and then exiting the bedroom.
"And don't forget about the wine that I had to go and buy." Ben called after his wife.
"As if I could." the sarcastic retort came back from halfway down the stairs.
***************************
Ben was up first on the Monday morning, as was usual, taking a shower and dressing before heading down to the kitchen to make the coffee while his wife took her turn in the bathroom then got herself ready for work.
Putting on the minimum of make-up; just a little eyeshadow and mascara, she brushed out her hair and then quickly got dressed.
Rolling a pair of neutral-coloured stockings up her legs she clipped them to her white lace suspender belt. Then, after putting on the matching panties, she slipped into the dark skirt and leopard print top she had decided to wear.
A pair of low-ish 2" heeled shoes finished off her outfit so that it didn't appear to slutty for work but sexy enough for her afternoon date with Nathan.
"What time will you be home?" Ben asked, handing her a cup of coffee as she came downstairs ready for work.
"Hopefully not too late. If I can get to your parents by four-thirty then maybe I'll make it home by six to six-thirty." She informed her husband as she made herself some toast.
"Not to late then?" he raised a questioning eyebrow.
"Well that all depends on your brother and how demanding he is." Abi told him with a chuckle, "But I'll try not to wear him out."
"Ok, I guess I'll see you sometime this evening then."
"I'll try not to be too late."
"Bye babe. Have fun." her husband kissed her on the cheek as he headed out of the door.
"Bye." Abi called after him.
The day seemed endless to Abigail as she waited for four o'clock to come around. She had made an excuse to her boss about having a dentist's appointment so she could leave an hour early but the intervening time seemed to crawl by. Finally, at just before four, she was able to hurry out of the office and make the short journey to Ben's parent's house, arriving almost exactly as planned, at half past four.
Making a quick final check of her face and hair in the vanity mirror she slipped out of her car and walked, casually, up to the front door. Her heart racing at the anticipation of what she was about to do and she could feel the dampness soaking into the crotch of her white lace panties.
"Hi Nathan," she smiled as he appeared at the entrance while she was still a couple of steps away.
"Hey." He ushered her inside and had no sooner closed the door than she slid her arms about his neck.
"Are you ready for me?" Abi giggled and leant up to kiss him feeling the hard bulge of his dick pressing against her as their bodies came together.
"I sure am.... H... how long do we have?" he stammered wrapping her in his grasp.
She shrugged "Not very long really, I promised Ben I'd be home by six o'clock."
Nathan swallowed nervously "He knows where you are?"
"Of course, he does silly." Abigail wriggled out of his arms and slipped off her coat, draping it across a chair, "And, more to the point, he knows exactly what we'll be doing."
"Oh!" was all he managed to say as she took control and dropped to her knees before him, starting to unfasten his jeans.
"Fucking hell." Nathan gasped when she freed his erect prick straight into her small hand.
"Mmmmmmmmmmmmmm!" Abi didn't wait and slid her lips over his cockhead so her tongue could worm around the bulbous tip.
With his jeans and underwear half-way down his legs all Nathan could do was grab her hair and groan with pleasure as his manhood grew even harder under her oral ministrations.
"Ghhhhuunnnnnnn... Guuurrrrgggggg... Guuuurrrggggggggg!" taking the shaft deeper she sucked eagerly on his throbbing organ, tightening her lips around its girth.
She had had to wait all day at work for the opportunity to enjoy her brother-in-law's cock again and she was determined that she was going to savour the short time they had.
"Shit Abi... you're gonna make me cum!"
"Well, we don't want that do we?" she giggled, "At least not yet."
Gazing up at him she let his spit coated erection slip out of her mouth, then taking it in her hand she started to lightly tongue the crown smearing even more saliva across it.
"Yuuuuummmmmmmmmmmmmm!" with her fingers wrapped around his girth she lapped gently on the tip.
"As good as that is I really need to fuck you Abi." Nathan groaned after a couple of minutes his fingers still twisted in her hair.
She didn't answer. Instead, she got to her feet and reaching up under her skirt she slipped her panties down her legs, letting them pool at her feet, before kicking them aside. Then rucking her skirt up around her waist, she bent forwards across the back of the sofa with her feet spread wide apart.
"We don't have long, so just go ahead and fuck me then." She looked back over her shoulder and blatantly ordered him to take her there and then.
For a moment Nathan stood and stared at his sister-in-law, her long stocking clad legs open wide with her pink slit peeking out tantalisingly at the top of her thighs.
"Fucking hell Abs!" his groan was one of total lust, "You're wearing stockings."
"I hoped you would like them." Abigail giggled and wiggled her backside at him, "So, the question is, are you going to screw me or just look at my nylons?"
Her invitation was immediately accepted and he shuffled forward, his cock standing out like a lance before him as he guided the head between her moist lips.
"Oh!" Abi barely had time to utter a sound before he drove his full length all the way into her forcing her up onto her toes.
"Fuckkkkkkkkkkkkkkkkkkkkkkkkk!" the second word she spoke was much louder and echoed around the room.
Grasping her hips Nathan started to fuck her, slowly at first, taking his time to slide his throbbing shaft in and out of her juicy cunt. Her puffy pink labia clinging to his dick, folding in with each deep stroke, cushioning it and making their mating even more pleasurable for him.
"Uhhh... uhhhhh.... oh fuck.... aahhhhhh... yessssss!" breathlessly grunting he began to increase the rate of his thrusts, his hips starting to slap her arse every time he bottomed out inside her.
