My Wife Got Me Off With Her Ass

We'd put the kids to bed and I was on our bed looking at my phone when my wife came and kissed me for a while. She was obviously quite turned on and after finishing the kiss, she got off the bed. But instead of walking away, she knelt on the floor, with her upper body on the bed next to me, and started looking at Instagram or something on her phone. I could tell she was up to something, despite her not really explaining what she was doing.

I got off the bed and went to the en suite bathroom for a minute, then came back. She was still there, knees on the floor, bent over the bed looking at her phone. Her ass facing me in tight black leggings. There's no way she'd normally do this, so I knew she wanted it.

I came and knelt down behind her, then gave one of her buttocks a gentle squeeze. She immediately responded by subtly pushing back against my hand. I parted her legs and adjusted my position so the stiffening bulge in my trousers was pressed against her from behind. Running my hands round to her front, I found her loose top hanging down, providing easy access. I slid my hands underneath and into her bra. Gently rolling her nipples between my fingers, they were already hard.

After a couple of minutes of clothed teasing like this, I pulled her leggings and knickers down to expose her smooth, waxed pussy and asshole. Taking out my cock, I let it sit directly between her buttocks. She went wild with excitement and began rocking back against it so it would rub against her asshole. I grabbed her hips and softly bumped against her in a simulated fucking fashion, which I know gets her going. I diverted one of my hands round to begin playing with her clit.

I realised now that she wanted me to cum up her back like this. I told her to wait a minute, and I fetched some lube from the drawer nearby. As she continued rubbing herself with her hand underneath, I dripped some lube above her asshole and let it run down to her sticky pussy. She gasped as she felt it running down. I returned my stiff shaft to its position between her ass and started to slide it up and down. Covering my cock, her lips and ass in slippery lube got us both even more excited, and with our plan unspoken but definitely decided, we went to work.

I let her rub herself as I held her hips and 'fucked' my cock up and down between her buttocks. With my other hand I continued to reach round and pleasure her breasts - groping, squeezing, pinching her nipples gently. Unable to contain herself any longer, she came hard on her fingers with the feeling of my hot, thick shaft up against her from behind.

To my surprise, she still desperately wanted me to finish, and so I let myself enjoy it. I grabbed both hips and increased my pace, sliding my cock up and down until I was ready to explode. She helped by pressing back, matching my motion, aiding me with her slippery ass. Eventually my cock began to twitch, and high pressured spurts of cum shot out up her back, all over her top. The second load of cum pulsed out above her ass and, as I continued to pump it out, it leaked down my shaft and everywhere. I made a mess as I slid and smeared it all over her asshole. I did have to put my hand beneath my cock against her pussy, to stop it dripping all over the carpet!

As I stood up to fetch some toilet paper to clean up, I took a last look at her bent over the bed with her pink, flushed post-orgasm pussy lips all sticky, along with her glistening ass and buttocks a mess with cum and lube.
