How I finally came inside my sister in law [MF]

Hello all!

Let me first give some quick background. My sister in law is in a sexually frustrating marriage. Her husband has been really sick, chemo, the rest and he can’t perform. They’re still strong but whenever she can hint to it, she’s wanting to get laid, and has revealed she’s very sexually adventurous because of it, including her past of liking anal, giving blow jobs at parties, etc. Basically dropping hints all the time that she’s ready again to get wild but is just stuck. She knows how we are as a couple and has expressed before that she’d love to party with us if my wife wasn’t her sister. Thankfully we didn’t have to cross into any weird territory for her to finally get some relief.

A few weeks ago they were all in town for a visit, their mom and even the husband, for a family gathering. During the party there was a bit of a ruckus and the SIL got very upset by some comments a distant family member made. In those comments she was very hurt and basically sobbing. My wife was busy with dinner and the sister was looking for a shoulder to cry on, and her husband was taking a nap from being sick (turns out he had some issues that later put him in the hospital). Because she was upset and had no where else to turn I was the shoulder for her to cry on.

I did my best to console her, holding her tiny body tightly and letting her get it all out. She looked up at me and said she needed to be alone, she wasn’t able to stop crying. I told her she could go up to the third floor bedroom and get privacy, but before going up the steps she asked me to go with her. I checked with my wife, who laughed, and said to go for it.

When we got up to the bedroom we sat on the bed and I offered my embrace to help her feel better. When she came to me she threw her legs over my lap and curled up right on me, telling me how safe I mad her feel. She kept crying for about a minute or two before (finally!) changing her mood a little. She looked me right in the eye as she squirmed a bit using her thighs to feel for my cock. She was out of practice so it was obvious what she was trying to do.

Of course, it worked. I had been hot for her for some time and knew she needed sex, being a former fitness model, most people would beg her for sex. Having her in my arms, so close, I was completely aroused and I knew she was trying to get us alone. When she found my growing erection she thrust her hand between her legs and just grabbed it, looking back into my eyes she told me she needed it, it was what would make her feel better. I simply nodded and went in to kiss her – where she stopped me.

Her fingers found my zipper and opened my pants. Reaching in she found precum on my tip and rubbed it as I reached down and pushed up on her clit through her jeans. While she wrapped her fingers around my hard shaft I started to unbutton her pants – which simply disappeared onto the floor. Before I knew it she had my cock out and she was starting to climb on top of me.

I, instead, pushed her to the bed – she smiled up at me, pulled up her shirt to reveal that tight tummy and nice tits. Here I was on top of my sister in law, ready to plow into her, just as I had dreamed. However, there were people in the house so we had to be very careful. With my cock dripping precum on her thighs I pushed into her, entering her dripping cunt. She started to moan and I covered her mouth.

She held me tight as I put my mouth on her ear and told her to be very quiet. One hand on my ass she pulled me deep into her, as deep as anyone has been in five years. Her legs went up and wrapped around me, I could feel her flexing against my cock and squeezing it – she felt like nothing I’d experienced – absolute perfection. I only pumped a bit, mostly grinding my tip deep in her and her clit against my body – her legs opening and closing around me as I did.

I kept telling her how great she felt and she just whispered back “thank you, thank you!” as I grew harder and pushed deeper. We were being very careful to not make any noise as we were locked in together. My mouth found her nipples as I kissed down her neck, which made her grab onto my cock tighter. I found out later that no one has even sucked her nipples in 5+ years.

We continued to hump quietly as much as we could until I just couldn’t take it any more. She felt amazing and though I wanted to absolutely pound her, she didn’t need it. She wimpered and whined as she felt me get closer, she knew that she felt great and how sexy she was.

“Please cum in me, please, I need it”

Which is all I needed to hear. I pulled her legs up to my chest and quietly pumped my entire cock into her, my tip popping her open over and over slowly.

“I’m going… I… I’m … I’m going to….”

I said as I got there, not even believing what was happening. She looked right into my eyes and I finally thrust deep, holding my cock in her while I grinded into her. Her beautiful face did it, that look in her eyes, and I felt it erupt as did she. I then thrust into her 4-5 times as my load blew forth from my balls and my shaft pulsated, a few times hard enough to make some bed noise.

“FILL ME UP PLEASE!!”

She said as she tightened up and suddenly lost it. Her body shaking she squeezed and gyrated on my cock, pushing back towards me, making that last rope of cum fly against her deepest spots. I was pushing up towards her gspot with my tip as she came a second time in as many seconds. Hearing that she was going to get loud, I had to cover her mouth again.

She just laid back and said “thank you” over and over. Being the responsible person I got everything together to rejoin the party. She then started talking about ‘next time’ and how we’re going to keep doing this when she could get rid of her husband. I had to leave through and check on things.

No one heard us, except for my wife, who listened through the door I found out later. My wife that night sucked me dry and pulled out some ropes onto her face. She tells me she’s not mad or jealous and happy to have helped her sister – but I think it’s started a competition. We’ll have to see where that goes.
