All characters are over 18. This is a work of fiction, and all characters, locations, and events are imaginary. This is a multipart series, and things start out slow(ish) but keep escalating.
There's a fair bit of anatomical terminology here, because the POV character is a nurse. Hopefully that won't detract from your enjoyment. I'll provide a short anatomical glossary along with some fun facts to help out.
Glans: the tip of the penis, distinct from the shaft, aka cock head
Corona: the flare or ridge running around the bottom edge of the glans
(Penile) Meatus: the slit-like opening at the tip of the penis, where urine and semen come out
(Penile) Frenulum: the band of tissue right below the meatus connecting to the foreskin (even if circumcised); this has plentiful nerve endings and many men are very sensitive there
(Scrotal) Raphe: the seamlike band of tissue running vertically down the middle of the exterior scrotum

I'm obsessed with my brother's penis.
I suppose I should back up a few steps. My name's Jen (not Jenny, not Jennifer; Jen). I'm 25 years old, and my brother Brian is 32. Technically he's my half-brother (mom was married twice) but we grew up together and he's always been there for me.
Brian's a tall skinny goofball, and if he weren't so damned hot I'd say he's too smart for his own good. He pulls it off though. He's been in one relationship after another since he was 16, always with phenomenally attractive women that make me feel small and insignificant in comparison.
I've always been short and curvy. Brian can eat anything at all and never gain weight, and I can't seem to slim down no matter what I do. I run every day, I count calories, and I'm still not in the shape I want. People tell me I'm attractive, and I've always had men (well, mostly boys) interested in me since high school, but Brian's always dated these tall supermodel types, and that's just not me. At 5'3" I'm usually pushing 135lbs, and my butt always strains to fit into the pants I like. That's one of two reasons I often wear skirts; the other of course is ease of access, because I'm a horny little thing.
Brian's been living with Cathy, his fiancΓ©e, for a year now. Thankfully we get along really well. She's just lovely, inside and out, and in some ways she's the sister I always wanted. We meet up at least once a week to shop or see a movie or just get some food.
She's predictably gorgeous, and despite being nearly 6 inches taller, she only weighs a little more than me. We even wear the same size bras (36C). It's just not fair.
I know I'm a bit weird about measuring everything, but it comes with the job. I'm a nurse in a pediatric ward. They usually work us for 12-hour shifts, three days on and four off, and I love the job but it can be grueling. There's a locker room but I usually wear my scrubs all day instead of changing at work. When I come home I'm ready to unwind, maybe have a glass of wine and watch something that I don't need to think about that much.
A month ago I came home to find my apartment building was on fire. There was smoke everywhere, and though it was dark and the complex's lights were all out, I could see the firefighters running back and forth and hear their yelling. A police cordon was set up and the officers wouldn't even let me approach.
I was exhausted and cranky already, and finding that all my belongings were either destroyed entirely or at best badly damaged (and in any event inaccessible) was just too much. I called Brian, and he and Cathy told me to come stay with them in their condo. I knew my renter's insurance would probably put me up in a hotel but I just didn't have the bandwidth to deal with it, so I agreed to stay that night, with the intention of leaving in the morning.
They plied me with wine and reassurances and were just the absolute best. I collapsed early in the guest bedroom, where Cathy had laid out a robe. All I had otherwise were my scrubs, underwear, socks, and shoes.
I awoke in the dark, lost and confused, and had a moment of total disorientation. I needed to pee, badly, but didn't remember where I was or why I was there. I sat up and oriented myself, and realized I could hear faint voices coming from upstairs, from Brian and Cathy's room.
I slipped the robe on; it was far too long and not quite wide enough around my shoulders and hips but otherwise fit well. I felt awkward and didn't want to disturb Brian and Cathy, so I moved as silently as I could, opening my door carefully and tiptoeing down the hall to the bathroom.
I could hear much more clearly in there; the bathrooms were one above the other after all, and their bedroom adjoined their bathroom. Cathy's muffled voice said, "Yes! Unh. Easy. Ow. Slower. Nonono. Not so... oh. Oh God. Oh God. Yes. Yes!" It sounded like she was talking into a pillow. Between words she moaned and grunted like a woman possessed.
I've had good sex. Hell, I've had great sex. But those sounds... I've never had an experience like whatever Cathy was going through.
Clearly she loved it, but clearly it was overwhelming her. And the most obvious reason Cathy would moan like that, in pleasure, was that she was being penetrated by something large. Large enough to be hard to take, large enough for her to beg him to slow down. Which was not something I expected to be thinking about, frankly, but I kept listening and kept thinking.
I could hear Brian, too, grunting faintly but slowly. Whatever they were doing, it wasn't just him jackhammering her. Which was a really odd thing to even imagine, but there I was imagining it. Vividly.
The most likely explanation was that they were engaging in anal sex, and Cathy was new to the experience. Thinking back to my first time, I could sympathize. They needed to invest in lube, clearly. And she should also look into learning to relax her sphincter.
I finished urinating and wasn't sure what to do. I didn't want them to know I'd been listening, but I didn't want to leave the toilet unflushed and my hands unwashed either. I agonized for a few minutes, but the truth is I was also enjoying listening, and I was feeling oddly conflicted about what I could hear. It was undeniably hot, but it was my brother making her make those noises. And that in turn led to a spiral of confusing and contradictory thoughts I wasn't ready to deal with.
In the end cowardice won out. I headed back to the guest room and fell back into a fitful sleep. At one point I had a dream that I was a donut, and the baker placed me on a wooden dowel that I could barely fit on. My glazing was smeared all up and down the dowel, and my cream filling was leaking out.
Dreams are weird.
Thankfully I didn't need to work the next day, and I'd set my alarm for 8am. I'd forgotten that Cathy works early, and I awoke a little before 7 to hear her in the kitchen. I could smell bacon and coffee, but I was so tired still that I fell back asleep thinking of food.
When I got up, Cathy was gone, and Brian was about to head out the door.
"Good morning. How are you? Did you sleep ok?" He had his briefcase in hand and was wearing a suit. I think he'd said something the night before about a big meeting, but the wine and stress and exhaustion had wiped it from my head.
"Yeah, I'm ok thanks. It's... I'm still processing, but I'm ok. And thank you both again for letting me crash here. I'll get my hotel sorted and be out before lunch." I could still smell coffee, and headed over to pour myself a cup, making sure not to trip on the robe.
"Look, you don't need to. Please don't. We'd love to have you stay here, Jen. Losing all your stuff... all the pictures of Mom... it has to be awful. It's a lot to go through. And I don't want you to have to stay in an impersonal hotel when you can be with family instead. We have plenty of room, and you're welcome to stay as long as you like. Weeks. Months. Years. Whatever you need." He was so earnest and so loving that I only protested briefly before giving in.
"If you're sure... ok. Thanks. I really... thanks." It was wholly in character for him, but I was still a little surprised, and was deeply grateful. Brian was the best brother ever.
"Oh, shit, I'm going to be late. Cathy should be home for lunch, but I'll be out all day. See you this evening. Make yourself at home, ok? Love you!" With that he rushed out.
