If I could, I'd buy OP a harem full of high end attractive hookers right now, just so he would keep his desperate d1ck away from that pregnant woman. I would!!!
I feel for her husband a million times over!!!
It is insanely hard for any man to learn, that behind his back, another man has been fvcking his wife/gf. Amplify exponentially that distress and heartbreak, with FOREVER being stuck with the image and knowing that another man's d1ck and cvm, was in your woman, while she is/was pregnant with (what he believes, at least at the moment, and very well still could turn out to be) his OWN child!!! Another's man's d1ck in there!
Many lives will be permanently and horrifically fvcked up by OP's choice to pursue this. Understand, I am NOT excusing the woman's previous indiscretions, her interactions with OP, or her potential willingness to be fvcked by him now. I am NOT. OP, alone, has the power and choice NOT to pursue her further and NOT to participate. I am NOT excusing her. I am asking OP not to participate and to find some other woman to get his rocks off with.
This woman's husband, in fact NO MAN, should have to face the horrid reality, of forever knowing another man's d1ck was inside his pregnant wife/gf, fvcking her, with child.
It saddens me tremendously that some men and women, think nothing of it.
If OP fvcks her, at some point her husband will find out. Her husband's pain will be incomprehensible. It does not have to be that way. OP can opt out.
