Dogging pt 2

I moved closer with a real bulge in the front of my trousers to get a better look. She stopped sucking for a second and Des said 'Someone followed us up and is watching from that bush'. It seemed to make no difference to Linda as she went back to work on him. Des gestured to the stranger inviting him to join but he must have been a bit shy as he watched for a minute and then went as quickly as he had appeared. I was now next to them both and leaned in and gently pushed Linda's head onto Des' cock so that it went deeper and she gagged slightly. I moved my hand down into her coat and under her top and discovered that she was not wearing a bra.I pinched a nipple and she moaned and took her head away from the cock and smiled. She was to look at a very normal woman but she had a gorgeous smile and a sexy laugh and a very dirty mind. Just as she straightened up Des pushed his cock back in his trousers and said 'walkers'. We all tried to look innocent and moved off in the other direction.
