This is basically a text conversation between Blaine and Sebastian about their kinky sex life. I don't know exactly the rating, probably M, they talk about sex stuff (also a not explicit mention of rape-play, just to warn you).
To: My Sebastian
What is the kinkiest thing we have tried?
From: My Sebastian
That depends on many things. Do you have a kinkiness scale? Why are you even asking? Are you trying to sext? Because I can't leave to jerk off right now. Sorry.
To: My Sebastian
Kurt just asked it out of nowhere before being distracted by a hat. He is in the changing room now. And, huh, I guess the less people do it the kinkier it is?
From: My Sebastian
Then our kinkiest thing was humping on the huge pile of freshly washed blankets while listening to your favorite disco hits and licking maple syrup out of each other's mouth before realizing the balcony door is open and the neighbors' Chihuahua is staring at us.
To: My Sebastian
Wait, what?
From: My Sebastian
Well, how many people do you think have done all that exactly like that?
To: My Sebastian
Oh come on. You know that's not what I was talking about.
From: My Sebastian
Okay… do you think roleplays are kinky? We had teacher-student, corrupt politician-meek househusband, knight-slave… and I think I forgot a few.
To: My Sebastian
The stripper-businessman and the doctor-patient ones. Oh, and remember when we borrowed Kurt's costume when I was the knight and he was so mad at us when he couldn't get the come stains out of the fabric? I still feel horrible about it!
From: My Sebastian
I think that was fucking hilarious, actually. I mean he agreed, didn't he?
To: My Sebastian
Well…
To: My Sebastian
I said I needed it to practice for an audition.
From: My Sebastian
An audition to get into my pants. Well, loincloth. Whatever, Kurt got over it. So… bondage? How kinky is that for you, baby?
To: My Sebastian
Eh, I don't know. We have never tried more than scarves/ties. Not even handcuffs, now that I think about it! Actually, we should try that Japanese bondage thing, what about that? Do you know what I'm talking about?
From: My Sebastian
No. Can I google it in public?
To: My Sebastian
I'm really not sure about that. Anyway, hm, chocolate sauce and whipped cream are something people joke about in rom coms so they are pretty tame. I can't believe I can't think about anything else right now! I thought we are pretty kinky!
From: My Sebastian
I googled 'kink list', Blaine, don't worry! Okay, so, we had foreplay in the bath and shower sex but I wouldn't consider those super kinky. Hairless genitals… eh. I like your curls at the base of your cock, they are pretty adorable.
To: My Sebastian
What? 'Hairless genitals' is on the kink list? And, um, thank you.
From: My Sebastian
So is 'exposure to the sun's rays', 'spiders' and 'staging one's own murder'. And these are only the ones that start with A. I mean the Latin names.
To: My Sebastian
I'm laughing and making horrified faces and the other costumers are all staring at me.
From: My Sebastian
Aw, sunshine, I'm sorry. But you were the one who asked! Oh, hey, we kind of tried rape-play once, what about that? That's pretty kinky.
To: My Sebastian
God, Sebastian, I can't tell Kurt I asked you to pretend to be a stranger who breaks into my home, slips under my blanket and threatens to strangle me if I don't let him make me choke on his dick before fucking my ass so roughly I could hardly walk for days! He is still not completely sure you are the best boyfriend for me and that would definitely not convince him.
From: My Sebastian
Come on, we used a safe word and everything, it wasn't wrong.
To: My Sebastian
I know but I don't want others to know. Especially my best friend. And Kurt would tell Rachel and Cooper and Cooper would tell my parents and… No.
From: My Sebastian
I think we found the one that is the kinkiest. I mean if you can't even admit it…
To: My Sebastian
… I suppose. But I still need to say something to Kurt. Or do you want him to think we have only vanilla sex?
From: My Sebastian
Of course not! Hm, well, toys?
To: My Sebastian
Riiight. Kurt has like a collection of dildos and vibrators, some of them limited series, luxury items. He wouldn't be impressed by that.
From: My Sebastian
He does? I'm not sure what to do with this information.
To: My Sebastian
Yes, and he has a size kink so… Anyway. About us.
From: My Sebastian
Exhibicionism? We like to grind against each other on the dance floor and show all those other guys that we belong to each other and they can't have either of us, no matter how hard they get seeing us make out.
To: My Sebastian
Yeah, I think Kurt noticed that. Every time the three of us go out to have some fun it ends like that and he is left standing in front of the wall holding our drinks.
From: My Sebastian
Well, we offer to be his wingmen all the time; he is the one who doesn't even try to go after some hot ass. Tell him we have rough sex a lot? I know that doesn't sound very kinky but if you go into details… The hairpulling, the biting, the nails digging hard enough into skin to draw blood, the pulled muscles and bruises…
To: My Sebastian
I have to go now, Kurt is asking me to go to him and tell him how he looks. See you tonight, babe.
From: My Sebastian
Have fun. And don't be too surprised if when you get home there will be some handcuffs and leather pants waiting for you in our bedroom.
