Keep the arms pinned

You looked Jan over, and even though there was a clear distortion at her stomach where her arms were being held against herself... you nodded a little. "Look, if I had a vote, I'd say keep things like this. I'm sure we can find something to do like this, unless Jan wants to stop."

"N-no, just wait!" Jan said, trying to fight the conflicting feelings of being manipulated in such weird ways to also getting a chance to do something truly intimate with you. "I didn't say... I didn't say I didn't want to do it. Just that I thought it would be awkward if I was, y'know... touching and stuff. But, if Jane is in control she's the one that puts my hands in all those places anyway, so... I mean, that's permission, right?"

"You bet it is!" Jane said happily, as the pants wriggled Jan's hips back and forth in excitement. "Oh, I can't wait to see what you think of your four-armed girlfriend, John!"

The outfit tugged Jan along briefly, just to go toward one of the drawers, where two black gloves hopped out and quickly aligned with the sweater sleeves. With the gloves in place, you almost had no way of knowing that there wasn't any arms inside them. It just looked like Jan had two normal arms, and... well, two spares dangling from her waist...

Jan was breathing quickly, almost hyperventilating at the thought of what she was about to do. But the outfit confidently strutted back toward you, shaking those hips and running the gloves up along her sides, before cupping the breasts. "Looks like you get to have a little playtime with us now, John! Won't that be fun. Jan, if you're ready to go, then you better get at that belt."

The gloves and sweater's arms stopped feeling up their own self, instead changing over to run along your arms and chest. The outfit pulled Jan closer, and her eyes were locked on yours, still in a confused, slightly worried expression. But, a smile slowly began to form after she got the hang of her freed hands in their confines... Jane kept her steady, so Jan could undo your belt in tiny motions, tugging bit by bit out of the loops and then loosening it with a flick of a finger. She unbuttoned and unzipped your pants, albeit with a little extra help on your end since her range of motion really was limited.

You could feel her hands touching around your boxers, feeling your rock hard appendage springing outwards, almost right into her palms. The clothes got into the action too, as Jan gripped at the fabric of your boxers the pants bent Jan's body down just enough to tug the fabric free. No longer confined, you felt Jan's delicate hands gripping your member lightly. Her range of motion really was limited, but she could at least lightly caress with her fingers and hands...

And then Jane joined in, pulling Jan by her hips backward, then forward. Back, then forward. That, plus the range of motion, meant the two girls were finally teaming up on a shared goal--to give you the weirdest moments of pleasure you may have ever endured! At least, up to this point...

Jan seemed to have relaxed much of her body, no longer fighting whatever it was that the clothes were making her do. Her arms and hands may have been trapped, but her legs were more willing to shimmy and move against your body, and you were just as happy to get in on the act as well. The ghostly gloves encouraged your own hands to run along the fabric of the body, occasionally pressing in hard enough to find that you were intrinsically touching Jan as well, while other times such as upon the larger soft breasts contained in the sweater, you knew you were only feeling fabric and thus only touching Jane.

It seemed that Jane was so satisfied with the cooperation both of you were providing her that she brought you and Jan even closer--your faces nearly touching. "Why not a kiss, then? A gift for you being so willing to help me try something new, Jan. I'm gonna be really generous with letting you join in on our fun as long as you keep agreeing to do things my way."

You were hesitant, but Jan wasn't. She swiftly leaned in the rest of the way to kiss you. You reciprocated, though it was strange to work through the thought that this was at your girlfriend's behest. After relaxing, you just gave into the motions and situation fully, and Jan's outfit squirmed and wriggled in delight, clearly happy that this was all going just as she pictured!

The gloves pushed you down further onto the bed as Jan was made to climb on top of you. Jan was a sweet girl who made dainty, calculated movements, but her clothes were turning her into a rather forceful tiger of a woman, someone who was confident in what they wanted, and Jan simply let the clothes take her there. The pants still vigorously thrust up and down, causing Jan's hands to glide along your erection with ease, finding a bit of lubrication in your precum that she used to her advantage in this assisted handjob.

And then, you couldn't help it anymore! You came almost without warning, and your sticky cum coated Jan's hands, as well as the crotch and thighs of the khakis.

"Aww, for shame, I'm gonna have to dress Jan up in something else now!" a ghostly voice said with a giggle, as she let the surprised but accepting Jan collapse right on top of you.
