Secretly making Sis-In-Law pregnant

 First thing to know my sister in law is a right stuck up prude of a bitch but I want my cum in her so bad. It all started after reading a sex story concerning two brothers who would rent out rooms to college girls. Anyway this got my interest up and I thought yes Lynn ( not her real name ) is going to have my cum inside her very soon. Step one. I had to get my brother to unwitingly spill a few intimate secrets about his wife and I found out she likes to masturbate with an ice cub inside her pussy. Step 2. I told my brother my wife likes to masturbate when I am away working and that she has a large tube of lubricant that she she uses and also where she keeps it hidden. I set up a few hidden cameras in our bedroom knowing to well that my perverted brother as I know he has always fancied my wife would soon be trawling through the draws sent there on a pretext that the mirrored sliding door was off it tracks and had to be repaired while my wife was at work. This would give him a few hours to jerk his fat cock several times producing huge loads of cum to go in to my wife’s vibrator lube. The thought of this made me really horny knowing my wife who had not had another man was to have my brothers cum inside her. Step3. After a few months of letting my wife use the spunk lube on herself I confronted my brother and showing him the hidden cam footage of him tossing himself off into the lube I then proceeded to black mail him by threatening to show his wife the camera footage. Step 4. For my plan to get my spunk into my sister in laws pussy to work my brother had to abstain from having sex with her for two months and as she was highly sexed I knew she would have to masturbate alot more to satisfy herself. To be sure my brother would not have sex with his wife I made him wear a cock ring chastity cage with myself only having the key so he could not go anywhere near his wife or let her see what he was wearing so this guaranteed the no sex rule. I did promise him a well deserved treat at the end of this caged torture but more of that later. Step 5. I arranged with him for myself and my wife to stay over at their house several times during the next two months which is when I put my plan in to operation and my brother had no idea what I was planning to get up to. So back to the ice cubes. Step 6. I made several excuses why I could not to go out in a foursome but said it was ok for them to go without me just so I could empty the ice cube trays and then over several hours I would empty my cock and balls of their cum into the trays and refreeze them in to ice cubes for my bitch of a sister in law to pop them in her pussy to masturbate herself off with. Two trays of 10 ice cubes each I thought would be enough on each time I visited their home and after the first visit all but one ice cube had been used. My sister in law was a dirty masturbating slut after not getting any cock from her husband for over two months. Then the news came that my brothers wife was pregnant. He had confided in me that for over the two months he had not had sex with her that she must have been fucking another cock to satisfy her needs. I reasoned with him not to say anything to her telling him she was to prudish to go and have sex with another man and he must have got her pregnant before the cock caging started patting him on the back knowing that I had indeed impregnated her womb with my jizz cubes. Step 7. On the last visit to his house I uncaged his cum throbbing cock and told him under no point should he knock one out to relieve the cum pressure in his cock or he would regret it for the rest of his life but to come to the spare bedroom we were in at 12 midnight when his wife would be fast asleep. What I had not told my brother that my wife had sleeping problems and she took sleeping tablets. Unknown to her I had given her a double strength dose which would keep her completely out for the night. While I was at I thought we don’t want to any interruptions so I slipped a couple of sleeping tablets into my sister in laws drink earlier to keep her cosy in bed. Dead on 12:00 Midnight the door to our room opened and my brother walked in. Lynn’s fast off he whispered. I know I said to my self. Just look at this video on my phone I told my brother. It was me jizzing in to the ice cube trays. The penny dropped it was you he said in a raised voice. I just grinned. Now get undressed as this is for you as I pulled back the bed sheets to expose my wife’s naked body. He instantly got the biggest hard on I had ever seen him have. ( That’s another story ). I said your treats right here. What! He blurted out. Don’t worry I said she will not know its you that’s been fucking her and even if she does stir from her sleep just whisper in her ear that this is the night she is going to get pregnant. The only thing I want to see later is cum ousing out of every hole from all that cum inside you. As I walked to the door I turned around and said I’ve not touched her so for a petite women she will be so tight. With that he grabbed her legs pulled my wife towards him spread her legs as wide as they would stretch ran his finger over her cunt lips and whispered softly bone dry and with this he thrust his cum throbbing hard cock straight inside her in one swift movement with my wife giving out a loud moan of pleasure. I watched for a few minutes my brother fucking my wife like a man possed for someone who had not cum for months and my wife enjoying it. As the door closed I heard my brother say where you off too. I opened the door and said to fuck your hot pregnant wife. Night…
