To fully appreciate the storyline and characters I recommend reading parts 1 & 2. Also, as always, if you aren't into consensual wife sharing you might be better off reading something you like rather than this particular tale.

"Oh god that was amazing Abi... I never imagined that it would be that good." Nathan gasped once he had got his breath back.
Abigail giggled sexily and kissed her brother-in-law.
"You were pretty good yourself. For a virgin that is." she grinned pulling her lips away from his.
Rolling off her to lay alongside him he pulled her against him and for the next few minutes they lay quietly together, snuggled up enjoying the slowly fading afterglow of their coupling. Letting him gently play with her breasts she sighed contentedly and closed her eyes basking in the achievement of her fantasy.
She could hardly believe what she had done. Her deepest, most private dream to be someone's first, to take their virginity had been realised. The fact that Nathan would always remember her for that sent a shiver down her spine.
"Are you ok?" he asked her after a brief silence.
"Mmhhmm... I'm fine. Just thinking."
"About?" he queried.
"That you had better drive me home in a minute." Abi eventually suggested glancing at her watch and seeing the time.
"Home... shit. Ben!" Nathan suddenly sat up in a state of panic, "What have we just done Abi... my brother... I've"
Sitting up alongside him she kissed his cheek and giggled "Silly. You don't have to worry. Ben knows everything."
"HE WHAT!" he turned to stare at her.
****************************************
"Ben knows what we've been doing." Biting her lower lip, she suddenly felt a little nervous as she looked at him coyly, "Well not the details exactly but he left me here knowing what might well happen."
Nathan stared at her disbelievingly, barely able to speak "What... how... I... I don't understand."
"Just give me a minute, I need the bathroom." Naked, Abi slipped out of bed with her hand between her thighs and giggled, "More of your stuff is coming out of me."
Stunned he sat up amongst the rumpled bedsheets trying to comprehend what his sister-in-law had just told him. Watching her bare backside disappear out of the door he tried to gather his thoughts and make some sense of what had happened over the last hour or two. He was still sitting there completely bemused when she returned a minute or two later and sat down next to him.
"So, the two of you just set me up for some reason?" he asked her immediately, unable to take his eyes off her nude form despite his obvious displeasure, "Did you really want to have sex with me or is this all some sort of game?"
"No Nathan, we didn't set you up as you put it." She shook her head, her long dark tousled hair swaying around her shoulders, "I'm sorry that you think we mislead you but that's not how it was at all."
The eighteen-year-old looked at her with a mystified expression "No? Really! Then please explain to me how it was then."
Patiently Abi explained to him how, with his brother, she had come to discuss the subject of her ultimate fantasy, to be someone's first, and how they had eventually come to choose Nathan as her prospective partner.
"So, it wasn't that you fancied me or anything?" he sounded more than a little disappointed, "It was just the fact that I had never been with a girl."
"Of course, you being a virgin was important. I can't deny that." Smiling almost innocently she shook her head again and took hold of his hand, "But you're also perfect for me. Cute, young and very fanciable."
"Well, I'm not a virgin anymore." He grinned sheepishly, "You've certainly made sure of that."
"That's true." She giggled sexily.
"But what do you get out of all this?"
"Well, I get to fulfil my fantasy." Abi replied candidly, "And remember that aside from your brother you're the only other man that I've ever been with, so that's a kind of first for me to."
"I guess so." he agreed somewhat self-consciously.
She kissed his cheek then turning his face to hers she kissed him firmly on the lips, responding to him when he kissed her back and forced his tongue into her mouth. Allowing him to pull her down onto the bed they lay together, still kissing, as Nathan ran his hands over her slim body, cupping and feeling her breasts.
"That's really nice but you ought to drive me home." Abi pushed him gently away after a few minutes noting that his cock was already hardening again, "Ben will be back from the airport otherwise."
"Do I have to?" he groaned disappointedly, "I really want to fuck you again."
Laughing she kissed him one last time and got up off the bed "You can have me whenever you want but not right now. Now I need to go home and get dinner ready for my husband."
"OK." he sighed resignedly and laid back watching her pert rear as she walked out of his bedroom to go downstairs and find her clothes.
Sighing he pushed himself up off the bed to follow her.
"Can I have you tomorrow then?" he asked hesitantly when he eventually caught up with her in the living room.
Half-dressed Abi paused as she pulled her skirt up her legs "Let me see if I can persuade Ben to go to the pub and give us an hour alone. Would that be ok?"
Searching for his own clothes Nathan grinned sheepishly at her "That would be great if you could."
Ben still wasn't back when Nathan dropped Abigail off and he happily accepted her offer to come in and have a coffee before going back to his parent's house. Closing the front door behind him he immediately grabbed Abi, his arms encircling her while his hands groped her modest breasts through her top when he pulled her back against him.
"Are you sure we haven't got time to do it again?" he whispered in her ear, nuzzling her neck at the same time.
Wiggling her firm backside into her young brother-in-law's very obvious erection she let him feel up her tits as she answered, "Yes I'm very sure we don't have time, Ben will be home soon. You'll just have to control your urges."
"But you said he doesn't mind me fucking you." He continued, sliding his hands up under her top to grope her bare breasts, trying extremely hard to persuade her.
Twisting her head to look back at him she replied frankly "He doesn't but I don't think either of you are ready to watch or to be watched yet. Don't you agree?"
"Probably true." Reluctantly, Nathan let her go rolling her nipples one final time before releasing her to go and make the coffee, slapping her rear gently as she went to the kitchen.
It was literally no more than five minutes later when Ben strolled through the front door to find the pair of them sitting in the lounge, mugs in hand.
"Hey Nath. Hi babe." He nonchalantly greeted his brother as if nothing unusual had happened and then came straight over to give his wife a brief kiss.
"Everything go ok?" she asked him trying to deflect his attention away from what she had been doing with his brother.
"Yeah, yeah we got there alright. They should be on the plane right about now." He updated them both as he checked his watch, "How about you two?"
"Oh us, we're fine aren't we Nathan?" Abi smiled naughtily and looked at her brother-in-law, who was blushing scarlet, as she answered her husband.
Obviously nervous and more than a little embarrassed Nathan put his cup down and got up, mumbling "Umm... yeah, yeah... we were... umm ok... I'd err.... I'd better get going."
"Catch you later." Ben casually called over his shoulder to his brother, heading out to the kitchen to get his own coffee, "If you need anything just give us a call."
Getting up Abi glanced after her husband as he left the room then quickly went across to kiss her brother-in-law "Bye Nathan, I'll let you know what Ben says."
"Bye Abs. I hope we can.... you know, do it tomorrow." kissing her back he turned to go.
"Me too." She said quietly to herself as she watched him leave.
"Well?" hearing the front door close Ben came back into the room with his coffee, "Are you going to tell me what happened?"
Abigail smiled guiltily "Well, in a nutshell, your virgin brother fucked me.... twice."
"Details babe. I want all the sordid nasty details." Dropping onto the sofa he grinned salaciously at his wife.
Moving across to him she sat on his lap "Maybe you should take me to bed first. Then afterwards I'll get you all horny again by telling you what actually happened."
"Deal!" her husband laughed and stood her up, "Now get your sexy little arse up those stairs."
Scampering ahead of him a giggling Abigail disrobed as she raced upstairs leaving a trail of clothing along the way. Completely naked by the time she got to the bedroom she threw herself onto the bed and opened her legs.
"Fucking hell Abs, that looks so inviting." Ben stood and gazed at her reddened, cum coated vagina as he hurriedly stripped off his own clothes.
Laying back with her slender pale thighs splayed wide, Abi held her hands out to him, "I want you inside me baby... please. I need you to fuck me."
Ben didn't need to be asked twice and mounted his wife, easing his bulbous cockhead between her moist outer lips before pausing for a second. Then he slowly slid his full length all the way up in to her cum lubricated pussy in a single stroke.
"Oh fuck.... yes, yes... fuck me baby... fuck your slut." Groaning with delight she arched her back up off the bed, taking every inch of his hard shaft inside her.
