Fumika-chan, my sister-in-law whom I met after several years, had surprisingly huge breasts and was actually a sex monster! She secretly pressed her breasts against me and seduced me! Then, she gave me a vacuum blowjob while hiding it from my wife! The act escalates more and more in a situation where I can't make excuses if I'm caught! My resistance was in vain, and I was ridden on my dick and forcefully creampied with a big-ass compression piston!! I have a wife... I'm being made to have forbidden sex with a continuous reverse impregnation press in a female-superior position that doesn't stop no matter how many times I cum, until my uterus is full...
