My mum rolled over, forgetting she had undone her bikini top and I saw her tits, her nipples were really hard and a lot bigger than I thought they wou...d be. My fingers were still covered in her cum so I rubbed her nipples and massaged her cum into her tits. This was good but was still not sorting out my bulging cock, could I really try and fuck my mum. I looked up and saw my brother was still playing at the other end of the garden, so I pulled my shorts down and out came my now massive cock.. She turned back to the mirror and no longer saw just a tart but a slutty tart!He asked her if she was ready and when she nodded he asked her to get on the PVC d****d bed. She sat on the edge of it and then slid back into the centre starting to feel very turned on, she could feel her cunt moistening up nicely and decided to enjoy herself. She got on her knees, thrust her chest forward and brazenly pulled her top open. The stranger immediately starting taking shots and she pouted and smouldered. Then I did it! I closed the var door. The click from the locks was something I will remember for some time. My only way to get home now would be to and walk. For two miles. Stark naked!I had to cross a main road at a traffic light and a car was approaching. I am not sure, but the driver/passenger(s) might have seen me. Then I walked along a walking path behind some apartment buildings. The feeling of exposure - of being stark naked and a long way from home- was making me head spin and I was. I just wanted to have some speed on to give me more time to find where their ejection handles were.I heard them coming, which confirmed they weren't supersonic. Had they been, I would've squeezed their fuel lines instead since I've heard somewhere that ejecting at supersonic speeds is REALLY bad for pilots.I sped up to about 300 mph, angling down at a good angle to be just a little slow for a collision, so they'd undertake me. I carefully watched them get closer and closer, waiting to see it.
