Me [F] 21 listening to my [F] flatmate get fucked in the next room

So I live in a student house with 6 other people. 3 other girls and 3 boys.
I’d say we’re all relatively attractive and pretty popular. We are all involved in various societies and are a friendly bunch.
Now for a variety of reasons, I have been going through a bit of a sexual dry spell over the last 18 months (we’ll blame the pandemic more than we’ll blame my terrible choice of men). Therefore any late-night escapades involve a mixture of – Reddit, pornhub, whatever toy I fancy or my right hand.
Whereas my beautiful flatmate Lena’s late-night escapades involve whatever flavour of the week she fancies.
I love Lena with all my heart. She’s my opposite – petite and tiny with a barely-there chest. We always joke that we wish we had each other’s boobs.
Lena is stunning, Lena is confident, but most importantly, Lena is loud. She is a little pocket rocket whose voice comes out of nowhere.
Lena and I’s rooms are on the top floor of the house, and we share a wall. I am treated regularly to the sound of her getting pounded into oblivion. While the first few times it annoyed me (and made me jealous), it now provides the best entertainment for me to touch myself too.
She’d probably kill me if she knew, but when I hear her and someone giggles and run up the stairs, I creep over to the wall and put my ear to it. I can listen to everything, her soft little moans as someone makes her feel incredible, her much louder moans as she is taken over the edge.
I can hear her going to town on whoever she is with and their groaning, their words, the ‘fucks’, and it turns me on so fucking much.
But the thing that gets me the wettest is the cacophony of noise that comes from her getting absolutely ruined in the next room. The headboard hitting the wall, the bed squeaking.
I’m lucky they get so loud because that hides the sounds of me in my bedroom. Muffling my moans with my arm or stuffing my panties in my mouth to keep me quiet.
It feels so good masturbating when I listen to them. It’s like my own private porno being played out in front of me.
I know what it sounds like when she’s about to cum, and I try to match my pace so I can cum at the same time as her. That way, if I accidentally scream, no one would notice.
Maybe one day I’ll tell her, perhaps she’d let me join in? A girl can dream.
