SINN-004 "I betrayed my boyfriend and let his father make a baby with me" This lowly cuckoldry! My beloved girlfriend was secretly having passionate sex with the desperate guy, cumming inside her over and over!

I really want to die... or rather, I have no choice but to die! My beloved girlfriend was stolen from me. And the guy who did it is my own father, who always looked down on me! They've been secretly doing it right next to me every time he comes over to our house. When we first met, she was so innocent and pure, but now she's completely smitten by his old man techniques... She's more lovey-dovey with him than with me, even having raw sex and getting inseminated! It seems her birthday present from him is getting pregnant.
