So you may recall that my wife sister led her astray with some Army guys a while back and that image of watching Susie in her finest being licked and fucked whilst her sister was on the opposite bed enjoying a couple of young squaddies.

Well since then I have probably seen my sil about twice and to the best of my knowledge she never knew I had spied on them both. Susie was having a party recently with all of her friends (about 10) and her sister staying over.

I had promised to keep out of the way so went to the gym for a game of squash. On my return the party was in full flow and judging by the bottles already consumed then it was likely to be a lively night. One of my wife friends Rachel had commented on my big biceps and grabbed my arm to have a feel of how hard my muscle was, bicep that is. Everyone wanted to grab my bicep and feel for them selves and sure enough one of her friends said "Susie does he have big muscles everywhere to which Susie replied Oh Yes and laughed it off.

So I bid them farewell and went for a shower. I was just stepping into the shower cubicle when, Rachel came in, apparently looking for the loo! I must have had a semi on as she looked and in a second grabbed my cock and placed my hand on her tits. If I had a semi on then it was now hard and Rachel was wriggling and desperate to be fucked. So with my wife downstairs and our new relationship do I fuck her.....Yep. Rachel lifted a leg up and moved her panties aside to reveal a very shaven wet pussy and in an instant i went to lick her out before I fucked her. She turned around and asked me to fuck her from behind and boy did i fuck her. Tight dress pulled up and cupping her tits and she bucked and thrusted like she had not been fucked for years. The whole episode lasted just a few minutes and Rachel wiped her self and left to rejoin the party with a parting kiss. As she opened the bedroom door to leave my sister in law was right out side and saw my semi hard cock and stepped in, closing the door behind her. She asked me if I enjoyed that and did I enjoy watching them both get fucked by the Army guys. So the secret that I thought i had, clearly wasn't secret anymore. She came towards me and put her tongue in my mouth and stroked my cock until she stepped back and said "I have wanted to fuck you for years but not tonight. She has since text me with saucy pictures of her in the same evening dress with stockings and her top pulled down to reveal her tits. Further messages indicating it was the young lady, Amy, I recall who let the cat out of the bag and asking if I wanted to fuck them both together.......Now let me think
