Fuck my half sister and got her pregnant

This was my best friend's chick until he took money from me more then 3 times finally she called me said she was sick of how he was doing that to me so I went to pick her up then kept her here with me she moved in for a a month I returned her to him later pregnant with my kid now he has to raise my kid he thinks is his but joke on him she is now pregnant again by me whenever he leaves she comes over to fuck he done said his self he never gets to cum inside her so he knows he not the dad but yet he don't know it's me again... Take my money I take ur bitch ...better yet he knows I'm fucking her still he can't do shit but bet he don't take my money again
