====================================
All characters are 18 years or older.
This story marks the start of ACT 2 of AMA: The Boyfriend. If you have not read the rest of the series, you really kind of need to for a lot of important context to what's going on. That being said - Act 2 picks up on an hour or two after Act 1 ended! This collection of short chapters was originally published on a daily basis, and are collected here for Literotica. In these chapters you can expect some MFF fun on the ride back to Vegas, a homecoming, and touching base with Robbie's multiple girlfriends and unlabeled partners.
The AMA was originally conceived of by Fantasy; this is just my version of the popular idea. Kudos to him and his original versions!

Chapter 340
The hot, heavy air of the desert washed over the side of my truck like a dusty warm breath as the transport truck blasted past us, the driver hanging on his horn in a blaring honk. Totally unnecessary - we'd pulled more than far enough to the side to clear the lane. I wiped my mouth and groaned, looking out at the hot afternoon desert. I was pretty sure we were in Nevada now, but it had been a little hard to keep track during the second half of the drive back home to Vegas.
"That's it, babe," Cassidy crowed, her big grin audible in her voice even though I was looking off at the horizon instead of down at my fiancee. She was hugging herself to me, her shirt pulled up over her tits to press them against my bare side. If we spent too much more time out of the truck cab we'd need to put on some sunscreen or risk getting burned. "Use those big, beautiful tits," Cassidy continued, sweeping a hand through the black, silky hair of my girlfriend Cattie.
A week ago, that would have sounded fucking insane to me. Now it felt completely natural, which had its own weirdness to it.
"Come on, Tiger," Cattie said, pulling my eyes down past my fiancee to her. More gorgeous, gothy-vibes model girlfriend was on her knees as I leaned back against the driver's seat of the truck, working her tits up and down my spit-slick cock energetically as she grinned up at me just as gleeful and loving as my fiancee was. "Give me that cum, Robbie. I want your cum, wherever you want it. I want it on my tits, and all over my face. Down my throat. You want to shoot down my throat, Tiger? I'll swallow it all."
I groaned as she laughed joyously, and Cassidy hummed her own pleased laugh as she ran her fingers through Cattie's hair again in an adoring sort of way.
A week ago they'd been best friends, Cassidy and I had been engaged and - I thought - entirely monogamous. Then Cass had sprung the source of her deep, cyclical depression on me as we'd been driving out to meet Cattie and a bunch of other cosplayers, streamers and models for a week-long working vacation at Lake Powell. She'd been getting eaten up by guilt for years.
The short version, and we still hadn't really sat down to get the full, long version because there just hadn't been
time
yet, was that just before the start of our senior year of high school, shortly after her Mom had passed away, Cassidy had found the Affection Multiplier App on her phone. It was magic - we had plenty of evidence of that now, both from before and from the week - and it gamified her relationships. It multiplied the positive effects of her interactions with others, making them stronger. A good conversation that could lead to a recognized acquaintance instead turned someone into a friend. But friendliness wasn't the only factor of Affection. The App also magnified Love and Lust, and hormonal, horny, eighteen-year-old Cassidy had become addicted to the power of seduction the App gave her. I'd already been crushing on her, loving her, before she got the App, and her seeing my 'stats' had only proven it to her. She'd had my love and swore she'd never needed any other.
Sex, on the other hand, with girls? That was her vice. A deep-seated one that she secretly indulged in frequently until halfway through our college careers.
Hundreds
was the ballpark number. And I'd never even known she was bisexual.
Looking back, I may have overlooked some of the signs
because
of the App. Not because she used it to do anything to me, but because the effect of the App made me more blindly accepting or unlikely to question her unless she was basically throwing it in my face. But then she'd hit a wall; a fellow college student who loved her boyfriend so much that, even with the effect of the App, Cassidy couldn't convince her to 'have a little fun.' The strain had made the girl break down, her desire for Cassidy warring with her love for her boyfriend, and she'd cut Cassidy off from the friendship.
That had been Cassidy's wake-up call, and she'd hit rock bottom. Dropped out of college, riddled with guilt and shame, dealing with waves of clinical-level depression, and there I'd been trying to help her through it without knowing the why of it all. That had probably only made things worse, considering it was her guilt towards me that she was trying to handle.
So, several tough years later and with our wedding less than a year away, she'd come up with a plan to properly repent and seek forgiveness - admit to what she'd done, tell me about the App, and start trying to give me the adoration from others that she felt I deserved just like she'd had. It was that last part that was probably an awful idea, but that she'd focused on and decided she needed to happen. And it would start with me being able to sleep with any of the hot, beautiful and quite possibly horny cosplayers, models and streamers on the work trip.
The plan, for how ill-conceived it was, hadn't accounted for a few important factors. The first was that girls who worked their careers in the online space were bombarded daily with kind of heinous, horny shit from their fans - there were plenty of good ones out, but the bad shit stood out. The space was also highly competitive, with lots of toxicity and drama that people slowly got used to. Stripping those issues away on a private trip, filled (mostly) with supportive folks with similar goals, put everyone extra at ease. Add a little alcohol and inhibitions dropped as playfulness rose. Then there was the fact that, apparently, Cassidy making it known she was entirely comfortable and open to sharing me out, made me extra-safe to flirt with and that built rapport quickly; the App likely had a hand in boosting that effect, too.
Then there was the fact that I, according to my fiancee and now multiple other women, was apparently 'extremely lovable.' I wasn't built to just hook up, I was built to make emotional connections. So a lot of the hookups that happened weren't just hookups.
The last element, though, was the big one that turned things on their head.
Bad relationships.
The plan had never been that hooking up with Cattie, Cassidy's best friend, would be the first nail in the coffin of her toxic-as-fuck relationship with her girlfriend Heather. If anything, Cassidy had thought there was a possibility that Cattie and Heather would have a threesome with me and things would otherwise remain the same. Then Heather had proven herself to be a contemptible bitch, and had pushed Cattie to the edge.
And hers hadn't been the only relationship that proved rotten. It
was
the only one that had ended before the trip did, though the others were pending.
"Come here, gorgeous," I grunted, reaching down and lifting Cattie up to her feet, mashing our lips together in a kiss as her tits pressed to my bare torso and Cass backed off a touch to give me room to move.
Cattie kissed me like she was desperate for a taste of my lips, which was silly because we'd been kissing for a while now - I'd driven the first half of the trip back to Vegas, Cattie coming to stay with us for a few days rather than getting trapped on a plane with her evil ex and backstabbing younger sister Sherry. Then, after I'd stopped for gas, Cassidy had insisted on driving and that I get in the back of my pickup truck cab with my girlfriend. Cattie and I had made out like teenagers, and she'd delighted in getting my hands up under her shirt and onto those glorious tits of hers. Then, ten minutes in, Cassidy had pulled off the side of the highway, climbed between the front seats and into the back with us, and Cattie had climbed forward to take over the driving. A little bewildered but mostly amused, I'd resumed what I'd been doing, just with my fiancee instead of my girlfriend. Kissing her lips, feeling her tits, burying my nose in her purple-dyed hair instead of Cattie's black-dyed longer locks.
And then, ten minutes later, they'd switched again.
They got pretty damn good at it. It took them less than fifteen seconds to make the swap. It would have probably been faster to just use the doors, but considering their tops came off as things slowly escalated, it was safer to not.
I spun Catherine with me, pressing her back to the driver's seat where I'd been. We had both doors open, nominally blocking the view of us from up or down the long desert highway, but as another truck blasted us with wind and honked at us I had a feeling their extra height was giving them a little peek at the action.
"Catherine," I grunted, leaning down and nipping at her pale, bountiful cleavage before hooking my fingers in her cotton shorts and pulling them down her thighs.
