Dealing With It A Different Way

So my brother in law and his wife have had this up and down relationship and for the last few years I have benefited from it. Kathryn is in her early 30s a few years younger then me same as her husband. It started after an Easter family function when the party went late and lots of drinking made what I did to her very easy. My in laws live out in the country and it’s very dark. There was lots of people to start but by the end of the night the only people left where the ones that where going to have ti spend the night. Kathryn is a skinny little thing with fake tits. She has a nice ass but her tits really stand out. I had been chatting her up and by the end of the night I had my hands on her titties feeling on them and pinching her nipples. She was sitting down and I was leaning over her while standing behind her. It was dark and I found she liked having her nipples played with. I pinched and yanked on them until I grabbed her by the hand and walked her over to a barn that had a work shop. Every one was hammered including Kathryn she knew what we were doing and at one pint she actually said we shouldn’t be doing this. I just lifted her dress and moved her thong over and guided my cock into her snatch. She did say no then let out a loud sigh and fuck. I gave her no time to get used to it and started pounding away. Making her ass clap got me going and I shot stream after stream into her. Her legs where shaking and she relaxed and I kissed the back of her neck while playing with her tits. I didn’t pull out she told me not to and I quickly got hard again and this time she was bucking into me. It felt really good and a short time later I felt her squirt on my cock then I shot my load again into her. I got her to clean me up i used her tongue to wipe my cock and balls up. I left a little bit in her hair and walked her back to the party. By now it was just us that where up. She stayed close to me I found my wife and her husband they where past out Kathryn then suggested we go to the living room where it was dark and we could mess around. Best Easter ever we fucked one more time this time slipped it into her butt had to stop she was being to loud. We saved it for another day which she did ended up taking it up the rear. She is very submissive and I have had a few close friends over and we have her her over to entertain and enjoy ourselves. We have had her airtight a few times this was the most intense orgasm she had ever had and she even mentioned how hard it hit her. 2 years and have fucked a lot. Has her in a gang bang and she asked that we don’t have more the 3 guys. She was bruised and sore for days. Planning a little camping trip with a couple of buddies and Kathryn in the only women going. She knows I told her that she was the only women going and her response was. I’m bringing lube so my ass isn’t so sore while we play for the few days. Honestly not sure how she hasn’t ended up pregnant. We don’t use condoms
