My Sister In Law's Breasts

I’ve always fancied my sister in law Janine; she’s funny, caring, beautiful, bubbly, plus has an enormous pair of tits! Don’t get me wrong, I love her sister, my wife, but I’ve always fantasized about Janine.

Janine married a complete ass hole. His parents were wealthy but lovely people; however, their son is an entitled, rude misogynist. I knew my sister in law was very unhappy; she even told me the first year of marriage was the saddest of her life! It was hard seeing such a lovely girl unhappy; at one point, I even had my shithead of a brother in law up against a wall threatening to kick his head in over the way he treated his wife.

Janine was desperate to have children. Unfortunately, it took five years and two miscarriages before she saw her first child David born. My shithead brother in law chose to be away a lot when David was a baby; we all suspected he was fucking somebody else or just wanted to steer clear of any baby responsibility.

It was left to the family to look after and support Janine during this time. As she lived on my root to work, I would pop around at least once a week on my way home to check on her. At this point, I’d known my sister in law for over ten years, and we had always been close. I sometimes doubt she would have even let me in the house if she knew some of the debauched fantasies I had about her! This particular day, I called to find my lovely sister in law in tears and highly distressed. Poor David was quite poorly, and the doctor had diagnosed whooping cough. Janine had had little sleep and was very distressed. I immediately called my wife, who was unfortunately busy with our children and couldn’t come around. In the end, I offered to look after David for a couple of hours so she could get some sleep.

The poor little chap was not well at all, and it took all my parenting skills and various rubs and vapour machines to get him to settle. Janine was asleep for over four hours and eventually got out of bed. She still looked distressed but thanked me for letting her get some sleep. I asked if my brother in law had upset her again, but she said no. I did pry as I could tell something was still wrong. David, at this point, was fast asleep. She became pretty embarrassed and said to me that due to illness, David had not been feeding, and her breasts were extremely sore due to an overproduction of milk. I asked if I could get her a breast pump as I knew my wife had used one to make up feeds when our kids were babies. She said she had one; however, her nipples had become highly sore due to using it, and David had refused to feed at all that day.

My wife had this issue a couple of times when our kids were babies and not well. I had stepped in at these points and ‘helped her out’ I didn’t mind the taste of human breast milk; it tasted just like sweet water to me. I told Janine what I had done for her sister and would be more than happy to do the same for her. She was not sure and didn’t know what to do. In the end, I took charge and sat her down on a chair and knelt in front of her. I opened her dressing gown, and oh my God, her breasts under her nightie were huge! She had a maternity nursing nightie that opened up at her breasts. She let me open up the cloth panel, and one of her breasts appeared. I’ve never seen a tit that size, and her nipples were extremely dark and also massive. I can’t even guess its size, but we are talking well north of EE’s


Her nipple was already expressing milk without even being touched? I gently took her nipple in my mouth and began to feed. I didn’t have to suck that hard for a torrent of breast milk to fill my mouth. Janine moaned a sigh of relief at the release. I must have fed for ten minutes on her left breast before moving to her right. Just before I did, she moved to the settee and rested her head against the back of the sofa. I opened her up the other cloth panel, and even I noticed the difference in size between the two breasts after I’d emptied the first one. I climbed on the settee and almost took on a babies position on her lap as I started to feed again. I kept out of my head that this was Janine tit’s in my mouth; I didn’t want to get sexually aroused. However, whilst feeding on the second, I got an enormous erection. Janine had her head resting on the back of the setter with her eyes closed. I gently rubbed the front of my trousers to try and get some relief without her seeing. After a couple of minutes, I was lost in lust and openly squeezing my hard erection as I fed and sucked this gorgeous woman’s tit. I then feel another hand on my erection!

Janine was looking at my suit trouser and squeezing my hardness. I released myself and let her take over. I had been dying to touch her tits and place a hand on the tit I was feeding on. She was now rubbing my cock over my trousers and doing an outstanding job. I started to squeeze her tits and feed from her at the same time. Next, my zip was down, and my cock was free; I loved her small hands working me. I’d not felt this hard in years, and I could feel my orgasm building. I broke off from her tit to warn her I was about to cum. Janine slides down the settee and takes my cock in her mouth. OMG, it was such a feeling; she was licking and sucking me, truly giving me the best blow job I’d ever experienced.

My head was at now at her knee level, and I separated her knees and caught a glimpse of her white panties under her nightie. My head drilled its way to her crotch. Seconds later, my hands are pulling her knickers to the side. OMG, she had really large pussy lips, totally different to her sisters? I ate her alive, savouring the musky taste of her delicious sex as I came into her mouth. She milked me, as I had milked her. My tongue was dancing around her clit as shortly after her body shuddered in orgasm.

Before I left we agreed that nothing like this would ever happen again, and that it would remain forever remain our secret.
