Trish and I had a bond which went further than brother and sister in law. We were always really close and had a sexual energy between us that we had never acted on, until last Friday.
We had been having our usual chat over coffee when we got to the subject of sex as we always did. Trish knew I had not been getting any action for a while, as my wife had lost the little sex drive she had and as usual Trish joked that she would help me out.
I pointed out what would her boyfriend think and she said "Charlie and I have discussed this and he wants you to join us. And he also wants to know what you would be up for, as he wants to suck a cock again after trying it for the 1st time?"
I realised Trish was serious and this was what I had fantasised about for years, not only having sex with my sister in law, but also having another man suck my cock.
"Are you sure about this?" I asked.
"Oh yes I'm sure, we have wanted a threesome for a while and we both want it to be with you."
"Ok I'm in. I would love Charlie to suck me and I would like to see what it's like to play with another cock myself."
Trish moved up to me, gave me a kiss and said "When would you like to do it?"
She turned around to the sink and I said "What about now?"
I moved up behind her and gently ran a few kisses over her neck, she gave a small shiver and let out a small sigh, I continued to kiss her soft neck as I ran my hands up under her shirt to cup her unfettered breast.
She moaned as I gently rolled her swollen nipples between my thumb and finger, her nipples swelled even more until it felt like I was caressing steel bullets.
"I see you accepted our offer. Shall we take this to the bedroom?" said Charlie as he came into the kitchen.
"Mmmm, lets." I said as pulled on both Trish's nipples and she let out a small gasp.
