A few hours later, after a shower and change of clothes, I met Anne at her Granny's house. I noticed Susan's car parked down the street from her mother's house, but didn't see her anywhere.
As I was getting the repaired computer out of the car, my phone announced an incoming text message -
"I'll be outside with the remote. Follow Anne's lead. Enjoy this, cuz I will. Susan"
I started up the walk to the house, and Anne fell in beside me.
"Did Mom text you? We have a plan, you know."
"Yes, she did. I'm still not believing this is happening."
"Want me to pinch you to make sure you're awake, David?"
"No," I responded quickly. I wasn't really sure what she'd pinch, and didn't want to find out.
Anne opened the door without knocking, and walked directly back to the kitchen. I waited in the foyer holding the computer for a few seconds before heading for the den to get everything hooked up. The machine was up and running by the time Anne and Mary appeared.
"Sorry to keep you waiting, David," Mary began apologetically.
I looked up from the screen, and saw she was wearing one of those sleeveless sundresses Anne had described earlier, and there was no doubt she was braless. The thin fabric of the dress formed snuggly around her jiggly mounds, and her huge nipples threatened to rip through the thin cotton of the garment.
Anne wasn't exaggerating about her Granny's nipples – diameter almost as big as my thumb, and standing over half an inch from the circle of her areola. Quite a site – I tore my gaze from her buxom display, and returned to the computer display, trying to be all business.
"Mary, I replaced the hard drive and re--"
"David," Anne interrupted, "Granny doesn't care about any of that. She just needs to get online, so let her have the chair."
Her tone was firm, almost bossy. I found myself relinquishing the chair without a second thought.
"Thanks you, David," Mary almost chirped. I'd never seen her this obviously cheerful – almost radiant. That could have been a flush of embarrassment caused by her flimsy attire.
As she slid into the desk chair, Anne moved behind her, and motioned me to get behind her as well. This viewpoint, looking over her shoulder down the front of her dress, had her tits and nipples looking even more pronounced. She squirmed in her chair, getting comfortable, as she began to open a web page that I recognized as an adult toy storefront.
Anne nudged me with her elbow, using sign language, cupped her crotch and pointed at Mary, twirled an imaginary knob in the palm of her hand, then discreetly point to the window slightly behind her right shoulder. Got it – Mary was wearing the clit vibrator, and Susan must have been just outside with the remote.
I looked to the window – there stood my smiling spouse, waving the remote at us. She mouthed silently what appeared to be a ready, set, go countdown, them flipped the switch to ON.
Mary froze in the chair, looking straight ahead at the screen, her hand not moving.
Anne quickly took over.
"OK, Granny. I thought you knew your way around this web store, Let me help," she offered, as she reached around Mary, resting her left hand on Mary's shoulder, and guiding the mouse with the other.
Mary flinched at her touch, and looked up at me, eyes wide. She thought I was running the remote. Anne pointed at the screen with her chin, looking back at me, mouthing follow me.
"Look, David. Don't you think these hooker pumps are subdued enough for me and Granny to wear in public together?" Anne asked.
I leaned around the left side of the chair, pointing at the screen with my left hand, and placing my right hand on Mary's shoulder as she continued to look up at me.
"These red pumps look too slutty," I commented, looking down, making eye contact with Mary. I held her blank stare without looking away, and saw her look to my left hand pointing at the screen, my right hand on her shoulder, then to Anne's left hand on the other shoulder, and Anne's right hand moving the mouse as she opened a new page of merchandise in the sex toys section.
Mary looked at the screen to see where Anne was going, and I stole a glance to the window to see Susan's grinning as she switched the device to the OFF position. Her mother's body twitched, and she looked around for the hidden operator – but Susan had ducked out of sight.
I saw Anne looking at her Granny's chest, and it was then that I noticed how much my mother-in-law's nipples had grown. From above, I had a new perspective on their size. Anne was right – these were Guinness record contenders that threatened to burst through the flimsy fabric.
"Granny, it's starting to get a little warm in here, don't you think? Why don't you undo a couple of those buttons so you don't get overheated?"
Mary looked up at Anne, who stared back. Apparently, the hesitation of even a few seconds was too much for Anne, who reached over with her hands, grasping the dress and pulling. Material ripped, and my mother-in-law's right breast was exposed. Following the lead, I ripped the dress back to expose the other breast.
What a phenomenal sight. Mary sitting at the computer with her breasts exposed, nipples pointing at the screen, as the flush of embarrassment and arousal swept up her torso, neck and cheeks. Susan was peering through the window, smiling, as she waved the remote.
Anne was back on the mouse, and had brought us to a page featuring nipple clamps.
"What do you think, David? Wouldn't a set of these look good latched onto Granny's big nipples?"
I was staring at those big nipples, which seemed to be getting even more erect. Mary looked up at me as I simply nodded, unable to tear my gaze from her exposed chest.
