Sister-in-law's blowjob continuation

This is the continuation following my sister-in-law's blowjob.

As promised, this is a true account of what followed my sister-in-law giving me a blowjob and is still happening, even now.
On the Saturday that I'd told my sister-in-law to come over, I was very doubtful as to whether she'd actually turn up. My wife had left for her concert about 8.45 so I was left home alone. I just wore a t-shirt and shorts as I wasn't going anywhere.
It got to 10.00 o'clock when all of a sudden there was a knock on the door and in walked my sister-in-law. She was wearing a long cardigan type coat and she'd left her long hair loose, she looked stunning. She sat next to me on our couch and removed the cardigan, to reveal her royal blue bra and thong. "I wasn't sure about doing this" she said "but after sucking your cock, I couldn't get you out of my mind" she said. "I have to have more of it" she continued. " I know this is your favourite colour, so I bought this set just for you".
I was actually flattered that she'd done that and leaned over kissing her passionately on her mouth. As I kissed her, I unfastened her bra and eased it off her body and groped her perfectly shaped firm tits. She gave a gentle moan as I sucked and nibbled her perfect nipples then snaked my hand down to her pussy, a pussy I'd dreamt of getting into for a couple of years.
I was absolutely delighted to find that her pussy was perfectly smooth, with not a hint of pubes, I'm really not a fan of public hair. She gave quite a loud moan as my fingers entered her pussy and reached for my cock over my shorts. While I finger fucked her pussy, she pushed my waistband down and grabbing my cock, started to stroke me. I started to finger her deeper and faster, rubbing her clit with my thumb as she gripped my cock harder and she started to buck her hips, clearly approaching an orgasm. She pushed her head into my shoulder and let out a long deep moan as she coated my hand with her juices. "Give me your cock, I need to taste your spunk again " she said, and dropped to her knees taking my cock straight into her mouth. "Mmmmmm, so big, so hard" she spluttered out while bobbing her head up and down. She's such an expert cock sucker, I didn't last very long before she got 5 long blasts of spunk straight into the back of her throat, swallowing every drop.
" I need you to fuck me" she said. " I need you to fuck me hard, I need your cock deep inside me, I want you to fuck my brains out, fuck me 'till I can't take anymore" She got on all fours and as I removed her thong, I gave her sweet pussy a couple of licks. She tasted absolutely fantastic, so instead of fucking her straight away, I ate her out to another orgasm, swallowing her juices that I'd wanted to taste for so long. "Ooooohhhh yyyeeeess, that was heaven, but get that cock inside me" I knelt up and with one lunge, pushed my cock in as deep and as hard as I could. "Owwwwww, your too deeeeep, it's painful and hurting. You're up in my womb if not deeper " she cried. To be honest, I didn't care (not very gentlemanly I know) but I'd wanted to fuck her for so long I was going to make sure she'd know she'd been well and truly fucked.
I hammered away at her pussy as she cried about how deep I fucked her when she lifted her head up and backwards and yelled out " Ooooohhhh shit, I'm cumming and I think it's going to be massive ". Her orgasm was so strong, she fainted for a few seconds before coming round only to go straight into another massive orgasm, only this time she yelled, screamed and shouted out obscenities. "Don't you dare stop fucking me 'till I tell you" she said.
I soon felt my balls tighten and shot off what seemed like a pint of cum deep into whatever part of her body my cock had reached. "Ohhhh God, I felt every spurt of your cum hitting my insides" she said as I pulled out and she collapsed onto her stomach. We fucked, sucked, fingered, licked, did everything we could think of all day whenever she got my cock up again, which she was brilliant at doing, taking quite a few loads down her mouth and in her pussy.
She was sat riding my cock when all of a sudden, in walked my wife. "YOU FUCKING DIRTY SLUT" she screamed at her sister. " HOW DARE YOU COME HERE AND FUCK WITH HUSBAND, YOU FUCKING COW" she bellowed. "I'm sorry, but I've been wanting to fuck him for years and I was jealous of you having him" my sister-in-law said. We were too close to cumming to stop fucking but my wife watched as we both came together. My wife had stripped naked and told her sister to get the fuck off me and sit on the sofa. " Get your fucking legs spread" she told her sister. My sister-in-law opened her legs slightly, but my wife just snarled at her "I fucking said spread your fucking slutty legs open, as wide as you can, NOW SPREAD THEM" she barked. My sister-in-law said she was sore, but my wife wasn't in the least interested.
"You've fucked my husband, now I'm gonna fuck you" my wife said. " But, but you can't, that's incest and I'm not a lesbian. I love cock and only cock" my sister-in-law protested.
My wife wasn't interested in what she said and dived in-between her sisters legs and started to lick and finger her pussy. "I can taste spunk so he's obviously cum in you" my wife said. My sister-in-law started to moan and buck as my wife tongued her pussy, so I stuck my cock in her mouth again for the umpteenth time filling her mouth yet again with spunk.
After my wife had ate her out and brought her to her to her god knows what number orgasm, she looked up at her sister and said "If you don't want all your friends, husband and everyone else to know what a slut you are, we will have this threesome of ours whenever we want it. Now get on your knees and lick my pussy until I tell you to stop"
After my wife had a couple of orgasms into her sisters mouth, she'd calmed down enough to talk calmly. "I've been bi for a while now" she told her sister. "Did you enjoy sucking and licking my pussy" she asked. "I must admit I did, can we carry on". Carry on we did for the next 12 hrs in allsorts of positions and combinations and we still do it today. It's fantastic having to incestuous sisters to fuck and watch, even though my brother-in-law hasn't a clue as to why his wife spends 2 weekends a month at ours. The only complaint I hear, is how sore they are after the fucking they get.
