This wasn't so awkward for me, cause I'm a troll, my sister on the other hand
About six years ago I left some porn out on my computer, normally I'm quite careful with my porn but for what ever reason I didn't that time. My sister came in and saw it, and I lied and said a mate had shared it with me, when in fact I was just, you know; jacking it.
Now a few days ago I was at my mums for a few nights and my sister try's to barge through my door, but I had since came up with a method of locking it (Katana wedged behind a free standing wardrobe and the wall with the hilt blocking the door). It takes me a while to open up and she asks "why was the door locked?" and adds "Were you jacking it?". To which I respond, "Yeah, I was fapping, so?" sarcastically
She had a friend over (I say friend, What I mean is fuck buddy. My family is a little fucked) and as I'm a brony they of course make assumptions, joke that I was in fact tossing my salad, remarking that the mate who I had said sent me that porn turned out gay and came to the conclusion that I'm also gay. I'll be honest, if I woke up next to a man I would not have to get rid of my dick or anything, but its not something I'd actively seek out. I would of course be the top.
Anyway the following day I'm talking to a guy under me on the phone, cause some shit went down or something, I can't remember. He's what we call a Magnificent Bastard, so he's pretty funny to drink with. He's had his tongue down my sisters throat before, but honestly I'm just glad she's not stripping at this point. So there is already some tention. Now he's taking my ear off at this stage so I put him on speaker so I can play Skyrim. And my sister comes in, calling him a fucking creepy mother fucker and shit, after about five minutes of that I tell her to go away, and then she says "Hey Zac, my brother's gay".
"Ok dear sister, what is your reasoning behind this?"
"Last night you know, you locked your door and were looking at porn"
"Imotosan, the only porn I look at is lesbian porn" (Used to be a true story, now I take notes from the masters)
"What about that time Tom sent you that porn, and he turned out gay!"
"Sis, that was ages ago... and I lied... I was pounding the pud"
"So last night you were actually... Having a date with Hannah and her five sisters!?!"
The look on her face when she realised I had a sexual drive was priceless
"And yes, I'm into arse play"
Zac, still on speaker phone fucking lost it.
As she walked away with that kind of ridged walk when someone hears something that they really wish they hadn't I yelled
"Oh come on! When one of your boyfriends Jilled you off right next to me while we watched 28 days later I SAID NOTHING!"
Edit: It was the same reaction she had when she found Mother's dildo. "Hey sis, guess where you came from? Because if it was immaculate conception I'll eat my hat daemon spawn"
