From "Bro" to Sissy Sub
My friend Magnus and I have known each other most our lives. We met in pre-K, when we lived a block and half from each other. Our families were close and we grew up side-by-side. We knew each other so long; we referred to each other as "brother." Magnus is only four months older than me, but that's not the reason he always called me "little bro." We had no other siblings and stayed close through childhood, went to college together, and married fraternal twin sisters, Flora and Nora.
While the twins were nearly identical, Magnus and I couldn't be more different. He was a giant 6'4" he-man, built like a lumberjack; and... I the exact opposite, a diminutive 5'6 1/2" with delicate features. In our last year in college, Magnus introduced me to Flora; he had his eye on Nora, but the twins sort of came as a set, so he asked me to be his wingman.
Though similar in looks, the twins had different personalities: Flora was quiet and reserved; Nora was lively and outgoing. These traits fit in perfectly with our (Magnus and my) dispositions. He was the outgoing, captain of the soccer team, big man on campus, always the ultra-social ladies' man. I was a dweeb, a nerd, who hid in my dorm room, playing online RPGs. I didn't really hang out with Magnus through most of college; his jock friends intimidated me, and he was kind of jerk to me when they were around.
Through high school, I had to stick close to Magnus for protection. College was less fraught, and we could each do our own thing, but stayed in touch. Magnus was in a frat and had lots of friends; I had two friends, as nerdy as me.
We met Nora and Flora senior year and started spending more time together again. It was clear right away that he and Nora were serious, but Flora and I--both quiet and reserved--took longer to get acquainted and form a relationship.
Nora and Magnus put pressure on us--Magnus on me, and Nora on Flora--to keep our relationship going. They had this romantic notion of the "brothers" (as we thought of ourselves) and sisters ending up married "happily ever after." Partly due to this pressure and partly by recognizing our similarities, Flora and I did get serious. Magnus and Nora got married right after graduation. Flora and I took another year.
After college, Magnus and Nora moved to the city, and Flora and I to the suburbs, and we again drifted apart; we'd see each other occasionally, but not like before. We would have the odd Sunday dinner at our place or go out with them in the city on a Friday or Saturday night. Their outgoing personalities would drag us out of our homebody shells, and we had fun with them.
We settled into married life over the next six years. Until tragedy struck: driving home late from work one night, Nora was killed in a head-on collision. She died instantly, as did the drunk driver, who ran into her. We were all shell-shocked, but Magnus and Flora were totally devastated; he was nearly inconsolable. It seemed Flora was the only one with whom he could truly share his grief.
He began spending more and more time with us, until he more or less lived in our small guestroom. He and I were still close, but I knew Flora (his lost love's twin sister) was the real object of his attention. I never really thought much about their closeness, as they were both so distraught by Nora's death. Flora was so blue; she would spend days without speaking, almost catatonic; only Magnus could bring her out of it. I'd try, but Nora and I were never particularly close; Magnus would divert her with memories of Nora, and they'd weep privately.
It had been three months after Nora's death. For more than two of them, Magnus spent at least three a week with us, and Flora sometimes stayed with him after work, in the city. I didn't ponder this too closely at the time. She would call teary and unstable and say he was distraught and couldn't be left alone. I would offer to join them, but she would wave me off, saying it was unnecessary, and I trustingly relented.
Then... one night, everything changed.
It was a Friday, and Magnus had come home in a manic upbeat mood. He brought dinner from our favorite city restaurant and two bottles of our favorite wine. He wanted, he said, to thank us of for the hospitality, letting him stay with us, and me for kindly "sharing Flora." He announced he had bought a house around the corner and was selling the downtown condo.
We were all happy with the news, I was glad to have Magnus permanently nearby, and yet out of our guestroom. And it was nice to see some of his garrulous energy back. We had a great dinner and drank down both bottles of wine, and Magnus and I moved on to Scotch. I was not used to drinking like this, and nearly blacked out in bed, next to Flora who had preceded me.
I awoke hours later, around midnight, groggy and with an urgent need to urinate. Flora's side of the bed was empty. I saw a sliver of light under the door of the ensuite, assumed she was in there, and walked out to the guest bath on the opposite end of the hallway by the guestroom. I tiptoed into the bathroom so as not to wake Magnus and closed the door behind me. As I was waiting for my pee stream, I thought I heard something like a faint mewling.
I peed and flushed, but in the ensuing silence, as I was about to walk out, I heard it again, then a mumble, like maybe Magnus snoring or talking in his sleep. Between the guestroom and our bedroom were the hall bath, my home office (formerly the larger guestroom) and a narrow storage room. I walked back to my bedroom and found the ensuite door still closed with the light on and knocked softly on the door to see if she was okay.
I worried the wine had made her nauseous, though she actually had very little. Magnus and I had drunk most of it. In fact, as I recall, Magnus had made sure my cup was never empty, so I might have drunk most of the wine, and then he insisted on Scotch; teasing me for being such a lightweight.
Not getting an answer, I opened the ensuite door, to find it empty. Curious where she might be, I went back out in the hallway, where the mewling was a little louder. I walked up to the guestroom door, from where I could now clearly hear a moaning and humming. I knocked softly on the door, still cluelessly thinking Magnus must be talking in his sleep, but I noticed the light in the room and knocked again, a little louder.
"Yes!?" Magnus answered from inside in a somewhat irritated, but alert tone.
As I walked into the room, I nearly fainted from the shock of what I saw. Magnus sat on the edge of the small single bed naked, his muscular legs spread wide; my beautiful wife was on her knees in front of him, also naked, her hands tied behind her back with a thin rope. His massive cock rammed down her throat.
As she sensed my entrance, she instinctively moved, as if to back away and off her knees. But he had a belt around her neck and used it as leash to keep her in place, kneeling deferentially with his dick down her throat.
"I didn't say you could stop sucking my cock, slut!" He sneered at my sweet angelic wife, as he pulled her by the belt back toward his crotch.
"Uhmmm, gluggg, ummgug, glug, mhmh, hmm," she hummed and gurgled in an apparent apology to the brutal monster.
I was enraged, devasted, and confused; I felt betrayed, heartbroken, sad and wounded. I assumed he must be forcing her into this. I thought, maybe losing Nora had done something to his psyche, to change my best friend into a rape fiend. I didn't consider my response long or very well, but ran headlong to protect my wife from her assailant.
