Mongoose Hunting and the Dark Car

I really want to put my head under my coat on her lap and get her amazing cock in my mouth. I think she has the same idea, and she goes to push my head towards it. I whisper 'I'm not sure', and gesture to those in the front and her snoring dad. It feels like we both know this is absolutely ridiculous, but just waiting for the other to say it before we stop. 

'Maybe I can pretend to go to sleep on your lap, and then I can put you in MY mouth', she suggests. I like this idea. Suddenly my father calls into the back, 'what are the two of you whispering about back there'. I quickly sit up straight to hide my erection and she pulls down her skirt. Has he heard all the noise of my belt knocking around, and our saliva swapping kissing.  'We're just playing a game to pass the time', I reply. After a short silence he continues, 'we'll be stopping soon for a toilet break anyway and to stretch our legs'.

Lara's father wakes up, and is happy with this plan. He stretches. Lara and I just stare forwards. The streets are a little more well lit now and with her dad now awake, this is likely the end of our fun. We have gotten away with a lot, but it's too much to expect it to continue. It's good that we've quit while we're ahead. But I'm still horny. I reach my hand behind her to grab her butt through her dress. I can't help myself. 

I move my hand under her, and I move my hand under her butt. She grabs the front of her dress and lifts the back of her dress up, so now my hand is under her bare ass. I feel her butt hole pulsing and opening against the palm of my hand. I rub it with my index finger. It starts to open. I notice her breathing has changed. She licks her hand quite smoothly and puts it between her legs and rubs her fingers against mine to add some lubrication. The pulsing continues and I start to push my finger against the opening. It opens and my finger slips in. She makes a noise. 'Are you ok Lara?' her dad asks. I freeze. My finger is in his daughter's asshole. 'Yep just a sneeze', she replies.
