A sobering experience

Sarah stood up while continuing to look at me, pulled her knickers down before sitting down next to me and hitching her knees up to give him a good view of her bare pussy, “is he awake” Lee asked while standing with his cock in full view, glistening with Sarah’s juices.
“I don’t think so or he’d have said something wouldn’t be?”
With that Sarah sunk down on the bench a bit more to move her pussy closer to the edge of the while Lee tried to kneel in front of her but couldn’t, because the floor was too hard and gravelly.
“Argh! Can you lie the other way? This way isn’t going to work” He moaned, “But I’d have to put my head on his lap, and he might wake up!”
“I doubt it, and it won’t be for long believe me” Lee muttered quite aggressively.
Sarah agreed and sat back up and swivelled to get into position before placing her head gently on my left leg and once again hitching her knees up, looking at me the whole time for signs of life.

I couldn’t believe what was happening! I was in shock and turned on beyond belief all at the same time, my stomach felt like it was tying itself in knots but it felt good.
The strange thing at the time was that I was more worried she would notice my hard cock against the back of her head and they’d realise I was awake!
Maybe it was the drink or the shock, but I was actually more worried about getting caught?
When really I should have been more concerned with kicking off, or at least getting up and walking away.
