Three weeks had past and it was the same, Damian sneaks in and fucks Tanya, she didn’t even bother protesting anymore just accepted it or even encouraged it, tonight was different before Damian could sneak in Kate walked in and to her shock of her sister grabbed her off the bed to collar as she fell to her knees, “Want to fuck my mate? Well now you have another person to worry about!” Kate took off her dressing gown and revealing her fake cock spat, “On you better lube it up, because this is going in your body!” Tanya shrugged before commenting, “No sweat...Damian’s is way bigger! He isn’t your mate, I see it now...He doesn’t want m...” she was met with Kate forcing her cock into Tanya’s mouth, “Suck it whore!” she **** it forward further into her mouth causing Tanya to reluctantly accept it, “Good pet, this is the beginning of the rest of your life, I will bear his children, I will be his partner, I will share his bed and take his luxury cock whilst you will serve us!” she slapped Tanya’s face before dragging her onto the bed facing the mirror Kate laughed, “Just think you will be eating your own sisters pussy out, suck her breasts and best of all cleaning her ass and feet with your tongue! You’d like that wouldn’t you?” Tanya grumbled as Kate applied an ball gag and being tied up she felt an massive dildo being rammed up her backside, “What’s that more? Okay!” she pushed it further in to Tanya’s pain and entering her vagina with the toy pinched her own nipples, “God this is so hot...Me fucking my sisters beautiful body if it wasn’t like this I would have loved to explore it mutually, may still do if you are an good girl now spread your legs wider bitch!” and hearing the door open in case Damian who staring wide eyed saw Tanya crying, “Damian nice of you to join us, come and fuck your toy!”
