While returning dad said "Andy tonight I shall keep the window of our bedroom open you can walk over the sunshade and peep in I shall keep the lights ...n and you can see your mom naked and have your fantasy fulfilled," I said "thanks dad" and put my hand on his thigh and rhythmically squeezed his cock as he had done mine earlier.We were now silently driving gathering courage I said "dad can I watch you fucking mom". Dad said," hmmm... I too was thinking that, and I really would like you Andy to. She wasn’t going to marry anybody. The last thing she needed now was to be pregnant. She needed to spend her energy on the station, not some man’s baby.But deeper inside, a primal part of her demanded to be allowed its chance ... to be allowed to step to the front and help her fulfill her destiny. It might not get its way ... she might not conceive... probably would not conceive, it told her. After all, this was only supposed to happen once. A quick fix. A way to blow off steam. The thought. She rubbed her finger over it and felt him fuck even harder up into her milking throat. The sweat had trickled down between his arse cheeks and the dampness made it easier for her to push her finger into his tight puckered hole. She slid it in slowly while Frank fucked her mouth and he bucked and thrashed. As her finger pushed in to her knuckle Frank cried out.“Oh God mummy, I’m cumming....I’m cummmmmmmmaaaaaaaaaaiiiiiiiiiiiiieeeeeeeeeeeeeeeeeee!” His body tensed, his balls tightened. Time. ‘Fine’ she announced, ‘but you’re not getting any from me tonight! And I was going to let you try anal.’ And she stalked off in the direction of his parents’ bedroom. Jacks eyes locked onto her tight ass as she swayed her hips on her way out. David, looked frustrated for a couple of seconds until his gaze fell on Jack, then he blushed. ‘Jack, go do your studies. I don’t want you slacking off just because you’re on holiday.’ Jack sighed as he left the table and made his way to his room. His dad.
