I just got the new kink, after reading a story on sexstories.com (called my secret). Mc has 2 dicks, has a relationship, but she doesn't know yet, and wants to break off because he never fully undresses, although they had mind blowing sex a few times (MC is MC of course). Then he comes home sad, because he is afraid of telling his GF about his 2 dicks, it's also why his first relationship before her broke off. Of course they had the same perverted interests, like incest stories and such. He comes home find his sister doing DP with 2 boys, she of course is angry until she find he has 2 dicks, MC being MC, has 2 full working 8-9 inch cocks, and in the end fucks her in both holes at the same time, and she has the best orgasm ever. Although from then on she regular fucks him, she sees he is still sad by the break up with his last GF.
His sister knowing his and her kink of incest, goes to talk to his ex, and they end up in bed having sex together, then she calls for her brother to finally join them, it's still a bit dark, and the ex still doesn't notice his 2 dicks, but he fucks them both at the same time. After both reaching the first orgasm, he fucks his GF DP, and she has a mind blowing orgasm and blacks out. Still not knowing he has 2 dicks, when she regains consciousness there is more light in the room and she see his sister and him standing nude over her, and then notices his 2 dicks, who by then have regained hardness. After a short period of being amazed, she takes both hands and kisses him deeply. And after a few blowjobs, going from one to the next dick and back. Both her and his sister, both go sit on hump one of on his dicks each while kissing each other.
And the lived long and orgasmic.
So now please someone add some details and make an AVN of this.
