My wife went to bed because she had to work weekends and my SIL and I stayed up and watched TV for a while. She decided to go get ready for bed and I ...igured I would also. I always slept I the nude but put a robe on and went out to the front room and soon my SIL came out of her bedroom and I almost died. She had a sheer see thru nightgown on with nothing under it and I could clearly see her pussy and tits. I had to cover my erection but she was a little tease and she came over to me and opened. I was hurt and asked what was missing that would let her get ready. I was shocked again when she said that she needed to be exclusive to the man she was to marry.I was devastated. I was angry. I asked Jane, that if she had not been exclusive to me, why did she let me think she was being exclusive. And when did she have time to date, other than weeknights.Jane angrily came back with; “I never said I was exclusive, I am dating others. You are the main guy, but I am not ready to be exclusive, much. You squeeze my breast as i take your cock in my mouth, Your hand tightens in my hair,pushing your cock deep in my throat, I suck you deep, in and out my mouth,My mouth is so wet dripping on your balls as you smack my ass hard,running your hand along my ass crack down to my soaking wet pussy.fingering my clit as your hard cock fucks my wet willing mouth.My hips thrust against your hand, as you push your cock deeper in my throat.Sliding your fingers in my pussy, rubbing your thumb around my tight. She seems relaxed as I work her legs sneaking a peak at her peach, it is hairy as shit just as I figured but showing some pink, so I am having the right effect. As I work her legs and upper thighs, I brush against her twat and she moans just a little. So I brush against it some more, then acting like I found a knot, I work right next to her cooch so that my hand is brushing it non stop. Anna starts breathing hard and I can tell she is getting turned on. I stop and tell Anna to roll over and let.
