THE SISTER IN LAW BACK UP PLAN

[neerathemall]

Lorna turned to me. 'Adam, shut up and give my little sister the good hard fucking she needs. I want to watch you screw her brains out.'

Instead of replying, I kissed down Stacey's body, between her breasts, on her stomach, her cute belly button, and then I was between her open legs, my nose pressing into her damp bikini bottoms, breathing in the clean scent of her arousal.

'Lift up, sis,' I said, getting turned on calling her that.

She did and I peeled her blue bikini pants down to her ankles and off her. I'd eaten Stacey's juicy pussy out earlier but it was good to be back between her legs. I gave her a few long licks up and down, holding her thick thighs open as she writhed on the bed. Her pussy lips were puffy, pink and glistening, her entrance waiting to be filled. I loved the little patch of hair above her lips, so different to my wife's completely shaved cunt.

The moment I had dreamed about and wanked over many times had finally arrived. I gave her wet pussy a kiss, then her swollen clit before I climbed back up her body into her open arms, braced above her. I nestled my hot cock between her thighs, letting my length rest on her warm pussy.

It suddenly occurred to me I wasn't wearing protection. I was always trying to get Lorna pregnant so we hadn't used condoms for years.

'Stacey, I-'

Our eyes met, serious for a few moments.

'You worried about getting me pregnant?'

Worried wasn't the right word. In fact my cock jerked against her pussy lips with the thought of it. Jesus.

'Aren't you?'

'No. In fact I came off the pill a few weeks ago '

I looked across at Lorna who was on her knees watching us intently and smiling.

I realised then that the sisters had a plan for tonight that went beyond just a threesome.

'Adam, I want you to fuck a baby into my little sister, ' said my wife. 'I don't know why we didn't think of this year's ago.'

My cock throbbed again.

'Stacey, are you sure about this? It means a lot to me that you would do this for us.'

My sister in law smiled.

'It means a lot to me too, bro. Plus, it'll be a lot of fun having you try to knock me up. We can practice a lot, right?'

'Right,' I said, light headed at the thought.

Stacey moved her hips and tightened her arms around my shoulders, and I felt the head of my cock brush her slick centre. I gasped at the contact. I would fuck her hard and yes I'd fuck a baby into her any day.

I didn't want to wait any longer and as I lowered my mouth to Stacey's, I moved forward and finally, finally after many years of dreaming about this moment, I slid the first few inches of my cock into her slippery pussy, opening up her lips with the width of my erection. She was tight and the delicious squeeze on the head of my cock made me throb.
