I have a yonger sister (super super short and thicc 19 yo girl, big ass tits), who got herself a boyfriend, and they were very much in love (haha). I knew for a fact that they fuck alot . "You sis gives the best blowjobs" is something he told me. Hated the cunt after that. Then on one faithful day, she and her boyfriend came over to our house, because the parents weren't fuckin home were they? They brough some fuckin voda and weed, and I get smashed every fucking night because I've got no life or friends, so I said fuck it why not?. We had fun, but then she went to throw up in the downstairs bathroom, and never came back (rude cunt). I went to check on her, and she was sleeping next to the fucking toilet bowl. Like by god, love, do you know what a shit shot the old man is!? So fuck her, I lock her in the toilet. Then I went to my sister's boyfriend, and he was talking some shit, I don't remember. I carried him upstairs, and he said 'ey cuz, the toilet'. So I took him to the toilet (cradling him in my arms like a wee bab), an he was so fucked up, the cunt didn't even noticed I was watching him take a fat log all over the goddamn floor (like jesus, what a prick). Then I took the fucker to my room, and put him in my bed. I could not fucking resist. So like a priest with a little boy, I took out his cock, and took a photo. Then I got really fucking horny, took off all his clothes, and mine >:). I licked all up his cock and ass, then I hate fucked the prick. Bloke moaned a bit, but was out like a little fucking baby. I came deep inside his ass... Yeaah, fuck him! Then after realizing what I did... I knew I was completely fucked, there's no way I can get all the cum out of there, and no way am I fucking licking up my own cum, that'd be gay as shit. But I did it anyway coz I'm a fag. So I put my sister next to him on the bed, but shit, man's ass is gaping. Maybe they do some weird shit, I dun fuckin know. Put a strap on from mum's collection there just in case ( don't asK ).  Whatever, all worked out in the end, next morning they apologized for fuckin in my bed because they were so fucked up. No one will ever know that I cucked my sister, that night (except me dad, had to tell him. Gave me a highfive). ANd my sister's prick of a boyfriend will never know that i emptied my fuckin nuts in his ass.
