I pulled the car into the drive after a long day at work, opened the door and went into the lounge. I was exhausted, I just slumped in an armchair. I shouted to my girlfriend, telling her that I was home, but I got no reply. Oh well, I thought, she's probably in the back garden. I got up, and took a walk to the back, but there was no sign of her. Never mind, I said to myself, I'll just go and take a shower, maybe she's popped out.
I took off my jacket and shoes, and then set off upstairs. As I got to the top of the stairs, I walked into the bathroom, then realised I needed to fetch a towel from my bedroom. I pushed open the door, and was completely shocked at what I saw. My girlfriend was home, and she was on the bed, with the woman from next door. They didn't notice me come in, and I just stood there and stared.
They were both totally naked, the woman from next door, Sarah her name was, was on her back, legs apart, and my girlfriend, Cathy, had her face between Sarah's legs, and was, from what I could see, running her tongue up and down Cathy's thighs. Both of them were panting loudly, Sarah's were shorter, more urgent. Just watching them was so erotic, I had forgotten everything, and was now totally focused on the two of them. I stayed where I was, and without thinking I shoved a hand down my trousers and inside my pants. This was better than any movie.
As I watched, Cathy moved her head slightly, and then thrust it forward. Sarah gasped. I looked to see what Cathy's hands were up to. One arm was supporting her, bent so that she was resting on her elbow, and the other hand was in her crotch. I guessed that she must be using her fingers for the same pleasure she was giving to Sarah with her strong tongue.
I regained just enough control over my body to move myself a little to the left, so that I could get a better view. It was odd, despite having walked in on my girlfriend with another woman, I wasn't in any way perturbed. I suppose I was just too excited by the sight.
From where I now was, I could see a little between Sarah's legs. I could see her hips moving sharply and regularly, rising up and pressing hard into Cathy's face. Every so often I could catch a glimpse of Cathy's tongue as it stroked across the outside of Sarah's vagina, across her lips. Then my view would be blocked as Sarah's head was thrust down. I had done that for Cathy before, and in my mind I could imagine the sensations, the hot, wetness of the inside as your tongue forces its way down, as deep as it can go, then wanders about, poking in all directions. The smell, overpowering, keeping you captivated. How I long to be involved in this, not just a spectator.
