Please note, for our first orgy experience, refer to my story: Hallowe'en Havoc. https://literotica.com/s/ericas-man-halloween-havoc
"I really want you both to come with me. Honestly, when I went with Kasey it was so well organised and safe... Please come. You know you loved the Hallowe'en one."
Alice had been trying to persuade Erica for about two weeks now, and with just three more days until the orgy she'd signed us up for, she was again trying to convince my wife, her older sister, that going to another fuck fest was a good idea.
She wasn't wrong, of course. We had loved our first ever orgy, nearly two years ago now, which we'd attended at the invitation of some of my work colleagues (and sex partners). It had been a fun night of debauchery, with Erica accompanied by her younger sister and their cousin, Kasey. We'd also met my two work colleagues, Holly and Nat, and I'd been lucky enough to take all five back to our hotel afterwards.
Erica grinned again, obviously running back the good memories in her head as I was. "It was pretty great," she chuckled. " I just don't know if you'd be able to cock-block as effectively on your own." She grinned at her younger sister. "You and Kasey took so much cock between you that nobody had anything left to pester me!"
Alice blushed a little, but smiled with the memory. Erica had been very apprehensive about our first orgy. She is bisexual, but generally much prefers girls, and for her own reasons had not wanted to fuck any other men, asking her sister and their cousin, Kasey, to 'distract' any advances.
I interjected, "Again, gorgeous, there's no reason you can't fuck the other guys there. I appreciate your dedication to my cock, but I've always said, if you wanted to include other men then I'd be fine with it." We'd had plenty of group sex over the years, but Erica had always involved only other women. "In an orgy especially, it'd be fine if you wanted to fuck anyone you wanted. Let's face it, you've slept with so many women with me over the years, it'd just be selfish if I had any issue!"
"See! Your husband is ok with it, so let's all go! He can help cock block if needed anyway." Alice knew she was repeating herself. She'd given all of these arguments over and over for weeks now.
Erica sighed. "I'll think about it." The same response as the last however many times.
"Too late! It's in three days! What is the issue?" Alice was clearly fed up, and I kind of understood why. I wasn't sure myself, why Erica wasn't really up for it. I wasn't bothered, particularly. I'd already made it clear I would be up for visiting another sex party, but Erica had always decided against over the last couple of years, and Alice had gone three times with Kasey. She'd always enjoyed them, and come back with some very erotic stories. This time, Kasey was unavailable, hence Alice's more determined pursuit of her sister's, and my, company.
"I just... I don't know," Erica admitted, sighing. She looked at her watch. "Anyway, I need to go and pick up the kids. I'm taking them to Mum's from nursery - you coming?" She looked to Alice and chuckled at her sister's irritated expression. "I promise I'll let you know tomorrow," she offered.
Alice pouted, but accepted that Erica was clearly done with the conversation for now. "I'll meet you there. I'll just nip to the loo, and then I need to nip for petrol, first."
As Alice disappeared upstairs, Erica kissed me and headed out to the car. We would clearly need to have a chat that night about Erica's misgivings regarding the orgy. I wondered what it was that was bothering her.
The car just disappearing around the corner, I felt Alice's body press against me from behind, her hand reaching around me and down the waist of my jeans to fondle my semi-erect cock, engorged a little, but without any serious stiffness after the discussion of the orgy.
"Your job tonight is to get Erica to that orgy," she whispered into my ear, her chest pressed against my back and her fingers slowly rubbing at my quickly growing erection. "I don't want to go on my own, and I want this big, thick cock inside me while I'm sucking on another." She reached up on her tiptoes and lightly bit my earlobe. "You don't want to miss out, do you?"
I turned and kissed my sister-in-law, fully ready to show her just how much I wanted not to miss out on her tight, little pussy, but she pushed me away gently after a few seconds.
"Not now," she breathed, her cheeks a little red. "Get Erica to that party and I promise you can do anything you want to me there." She paused and smirked at me. "Anything at all," she reiterated, her voice dripping with the implications, before she skirted past me, her stomach pressing against my erection as she passed, and waved cheerfully as she headed to her own car to follow Erica to their mum's.

"The honest answer, yes," I agreed, my hands roaming over my wife's beautiful body as she cuddled into me, my cum drying on my belly and her chest after a slow and sensual blowjob. "I love you, and usually I can guess how you'll react to pretty much anything, but with this... you're just a lot more indecisive than usual. The last three she's been to, you've said a straight no to her. Is it the fact she'd have to go alone that you're considering, or are you just not sure whether you fancy it or not?"
Erica sighed. "Ok. Honestly... I have been thinking about this a lot. Yes, part of it is not wanting Alice to have to go on her own. I know she'd be fine, but she wants the company, so I really don't want to leave her. Otherwise I think I'd have just said no."
