Last night with [m]y sis in law. [F] An ongoing polyamorous tale.

Since there was a groundswell of interest in my relationship with my sister in law, I decided to post about last night.

I showed her the post, and it made her happy. For all those asking for pics, she isn’t comfortable with that… yet.

Last night was our night to sleep together anyway, as my wife had a date of her own. Human beings are biologically wired for sexual competition, and so few things can add nitrous to a sex life like sharing a spouse.

Last night Lynn and I were in her room watching family guy re runs, when we suddenly started hearing my wife and her date having a bit of fun. We could hear the muffled sounds of wild moaning and slapping flesh through the walls, and it immediately made us both hot.

We looked at each other, that look evident in both our faces, and we just started making out. My boxer briefs had risen and there was a big wet stain of pre cum on the tip.

Lynn fished me out and quickly covered my purple headed yogurt slinger with her lips.

I wanted to fuck. The sound of my wife being deeply drilled had inspired a flow of blood like no other, and I just wanted to rut.

Lynnn swayed her ass into doggy position, and I rose above her. I sheathed myself, and wasting no time, I began to thrust hard and deep. My hips were a blur. Hell, the whole lusty night was a blur.

We fucked and fondled for a while, and I spilled for her twice. The first time I gave her my load deep in her cunt. We took a break so she could shower. We got some drinks. Flirted and cuddled in the messy sheets, and then resumed another round of animalistic, socially unacceptable relations.

Thanks for all the comments btw. The funny ones and the ones critical of my use of adjectives.
