The In-laws – Part 1 – The Sister

It’s so difficult having a sex drive higher than your Wife. Once again, I’m left hard and frustrated as she falls asleep.

That leaves me needing get myself off.

Slight problem with that is we are staying at my in laws, so sneaking to the bathroom to cum isn’t the most gracious act.

I creep out of the room and across the hall, passing her younger sisters room, and notice the door slightly open.

As I quietly pass the open door, I hear a soft moan, which stops me in my tracks.

“Mmm”. There it is again.

Curiosity gets the better of me, and I decide I’m too much of a pervert to not peak through the open door.

My sister in law is mid 20s, hot blonde with huge tits and a great ass.

As I peer through the door, through the darkness, I can see her bare legs, with a black lycra thong discarded around her left ankle. Almost as if she couldn’t wait to get it off and pleasure herself.

I look further and see her hand between her thick thighs. She’s pushing two fingers into her tight, wet pussy. I can hear it too.

Then I see her face. Eyes closed, mouth open. Complete bliss.

Without even realising, I’ve got my cock in my hand. I’ve fantasised about my sister in law before, but seeing her pleasure herself is something else.

As I adjust my boxers and pull my cock out, I move slightly and the floorboard creaks…

She’s immediately startled and see’s me. At the door. Staring. With my cock out. I’m frozen to the spot.

She stands up, wearing nothing but a black vest top. I can see her perfect curves, her erect nipples, and her immaculately smooth pussy. I can’t move.

She slowly walks towards me, not breaking eye contact, and grabs me by the face. Then she puts her fingers in my mouth, making me taste her. She tastes phenomenal. So sweet. I need more.

Then she whispers to me, “do you taste as good as I do?” And pushes me out of the door back on to the landing.

She again walks towards me, pulls her vest down revealing her incredible tits, and drops in front of me to her knees. Again, not breaking eye contact.

Then she slowly slides her mouth over the head of my cock, placing her hands on my thighs. Her tongue is swirling around my rock hard cock, making me squirm.

Then she sticks her tongue out, and starts slapping my cock against it. I had a feeling she was a slut, and now I’m getting the proof.

After licking the full length of my shaft, she slowly starts easing it in to her throat.

I loved watching her struggle as she tried to force it in. She wasn’t going to stop until she’d taken it all.

I decided to help her out, grabbing her head and shoving the rest of my cock deep into her throat. I continued to thrust it in and out, using more force each time as I fucked her mouth.

She was gagging and coughing, whilst drooling saliva everywhere. I became worried we might wake the rest of the house, but seeing her a sloppy mess with tears rolling down her face, I had to carry on.

I began fucking her face much quicker, I was ready to explode.

I saw her hand was back between her legs as she was rubbing her pussy again, whilst sucking my cock like a champ.

She was so good. So determined. So wet. I couldn’t contain it anymore.

I grabbed a handful of her hair, pulled her off my cock, and positioned her ready to unload on her face.

I stroked my cock frantically, and at the exact second I blew my load all over her pretty face, I heard a noise…

The light came on, and my Mother in law is stood there. Staring at me with my oozing cock in my hand, stand over her kneeling half naked daughter, with her face painted in my cum.

To be continued.
