Unexpected surprise.

This event will forever be etched in my memory as it was a complete surprise. Let me set the scene of how this all unfurled. We were at a family dinner and towards the end my mother in law took ill, some kind of food allergy, and the whole group took off for A & E leaving my 17 year old sister in law with me to walk back to our appartment. It was a lovely evening and we walked arm in arm talking about this and that. We had consumed a glass or two of rose wine at dinner so were feeling merry. Now my wife's family are Catholic so the strict no sex before marriage was assumed to be an accepted rule.

In the appartment was a divan with a box underneath full of board games, I knelt next to it and opening the lid I turned to her and asked what board game she would like to play. She came over in her very diaphenous shortish dress her small pair of panties visible through the material. I felt a little surge of arrousal as she swished along. She knelt next to me and taking the lid of the divan she closed it, turned to me and pulling my head down kissed me on the lips. Soon her little tounge was darting into my mouth and we enjoyed a long passionate kiss. Pulling away I said "that was unexpected but very nice!"

She said "would you like to play a little bit?"

"What have you got in mind I asked?"

With that she stood up in front of where I knelt, lifted her skirt up above her waist exposing her beautiful panties to me at eye level, with a dark strip of hair on her mound flattenned against the sheer material. I ran my hands up the back of her legs, inside her panties and squeesed her soft buttocks holding one in each hand. I could hardly breath with excitement and was already fully erect. I pulled her forward and pushed my tounge and teeth onto the mound of her pussy. Instead of pulling away she put her hand on the back of my head and pulled me on harder.

I took my right hand off her buttock and slid it up between her legs onto her panties and gently rubbed her there. Her little pants of encouragement made me bold.

"Can I finger you?" I asked.

"Yes" she panted.

Using both hands I pulled her panties down to expose her sex to me. "Take them off" she demanded so I pulled them right down and she stepped out of them. I immediately went to work running my hands back up her legs and slipping a finger between her lips into her pussy. My left hand was squeesing her butt and I was fucking my finger in and out of her pussy. It was a bit of a tight squeese so she lifted one leg up onto the divan and I pushed a second finger in working against her clit in little circular motions.

"God that feels good" she said.

"I want to go down on you", I blurted out, I could hardly speak I was so arroused by her excitement.

There was an armchair next to the divan so, walking on my knees I walked her into it, she sat down and I lifted her legs over the arms of the chair. I parted her pussy lips with my fingers and looked down on her open pussy that was wet and pink, she was mostly shaved but had a dark strip of pubic hair on top of her mound.

I went to work, rythmically fucking her clit with my tounge and finger fucking her at the same time. It wasn't long before her arrousal was at its peak I was pushing my tounge hard in little pulsing movements against the erect bud of her clit. "I going to cum" she sighed and her clit began to throb. Lifting her with a hand under each buttock I kept the pressure on until her orgasm spilled over. Her clit throbbed against my tounge and I stayed with her until she subsided.

I stood up and undid my belt and zipper, I pushed my jeans and underpant down in a single motion so that my erect penis was directly in front of her. She sat forward on the chair and took my cock in one hand she began licking the head and shaft with her tounge. She knew about giving blowjobs because she took my shaft in her mouth using only her lips and tounge I was about to explode. Holding her still I began fucking her mouth and came jetting a load deep into the back of her mouth.

Afterwards she licked my cock clean looking up at me she smiled. "Thanks that was lovely" she purred.

"Have you had a cock before" I asked.

"Yes she said, my Uni study buddy took my virginity two months ago".

"Thats exciting do you still fuck him?"

"Yes when we study we fuck first then study."

"Stand up I ordered, turn around and bend over" she eagerly complied, I lifted her skirt over her back to expose her naked butt. I stood with my cock pressed against her thigh and reaching between her legs I began to rub her clit back to arrousal, fucking three fingers into her pussy.

"I can't wait to fuck my cock into you" I said, "I want to fill you up with hot cum. Does your study buddy cum inside you?" I asked.

"Yes" she said "I'm on the pill".

"Are you going to tell him that you fucked your brother in law?" 

"No this must be our secret" she panted, "Oh God I'm going to come."

"Kneel on the chair", I instructed and pushed her forward spreading her butt cheeks open I found her opening.

My cock slid right up into her, holding her hips I eased in and out, working faster and faster until I climaxed deep inside her pussy. 

So much for saving herself for marriage! We cleaned ourselves up and watched telly until the others came back. I never got to do her again, although she did share some of her conquests with me. She became quite the little fuck bunny. I may share some of those stories one day.
