Meg was sitting in a corner glaring at everyone, I was sitting next to Josh flirting and making people laugh, everyone else was joking and dancing and... having a good time. After a while Meg came over and tried to start propositioning me again. She stood in front of me, stuck her chest out, and demanded I stick my hand down the front of her shirt. I said something like, "Oh Meg, you can't interfere with true love!" and stuck my hand down the front of Josh's shirt. Josh and everyone else went into. You might as well make yourself useful." She pointed at the right-hand seat and settled herself in the left. That amazing young woman just ... fit. She busied herself with assorted buttons, knobs and levers. The customary whine of a jet engine spooling up, followed shortly after by the second. I donned the headset, but absolutely was not going to touch anything else.Jen poked her finger. "Flaps. Undercarriage." then went back to what she was doing. "Tower, Golf, Echo, Alpha, Sierra, Golf.. Then she was coughing pretty heavy and i shouted over to her "are you ok" she replied "yeah im fine" but she sounded like she was choking abit. so i went over to her and said "are you going to be ok" she said "yeah2, then she said could i help her back to the car, so i helped her up seeing a flash of her knickers on the way. She sat in the car and she just said to me in usual drunk talk "I really appreciate what you have done for ****(friends name) over the last few years, since we was. Then I 100% involuntarily shot my load. It got on the bed and some of it got on them."Holy shit, Tim, that was a lot of cum you just shot," Marry said."I know, my sister fucking my girlfriend is so damn hot," I replied.Marry laid back and Emily climbed down towards Marry's pussy. She kissed her legs everywhere all along the way. I never ever in a million years would have thought I'd see my girlfriend eat out another woman, let alone my own sister. Although, it seemed like I was about to see it.
