Step Cousin Invited Me to a Threesome with a Lookalike Doll

My step cousin has a kinky surprise for me: he brings out a doll that looks almost like me and wants us to play together. What starts as teasing turns into a naughty threesome fantasy, with me riding cock while the doll becomes part of the game. A taboo roleplay full of blowjob, cowgirl, doggy style, and cum play, blending imagination with reality.
