Returning home for Dan and Alan was a sobering moment for both of them. They knew more about each other now than the vast majority of fathers and sons. They'd let go of any sexual inhibitions that either might have had and done things with, and to each other. But that was two thousand miles ago and the reality of coming home hit them.
Where they going to continue this incestuous relationship now they had returned to reality? Or, were they going to heed what Alan said at the beginning of their adventure that what happens in PDI, stays in PDI. This was part of the conversation they had on the last night and they agreed not to talk about it for a week on their return, but to just be as they were before going on holiday.
Alan arranged to visit Dan seven days after their return to discuss their next move. Were they to seek solace with other like-minded individuals and go back to the father and son relationship they had before they stepped through the curtain to the other side, or continue what they discovered on holiday? They had a week to think about it.
Deep down inside Dan wanted to continue this incestuous relationship. He got considerable satisfaction from being the receiver of Alan's lust and was very happy to take a more subservient role in his pleasure and allow him to do almost anything to him that didn't require clothes. But it was up to Alan.
Alan, on the other hand, was worried that Dan might call it a day and call it off. He liked having sex with other men, especially his father. It meant that they could go to the football, then for a few beers, and then go home for sex without the need for flowers and compliments. He also faced the fact that both had much to lose if it ever came out and should they fall out, he believed that nothing would ever be said. It wouldn't be good for either.
When Alan knocked on Dan's door it was with trepidation. He wondered how he would be received. Whether the magic of the holiday had disappeared or whether his father might feel guilty about what they had done, now that they were back in the real world. There was only one way to find out.
Neither needed to have worried. They greeted each other warmly and openly talked about their holiday with fondness. They talked about the sex they had indulged in, between themselves and others, and agreed it had opened up a new life for them. They wanted more, and after a week of celibacy both were eager to let off a little steam in the bedroom so up the stairs they went undoing their clothes as they went.
Upstairs, it was a race to get naked. There was an urgency, by both of them, to consummate what was going to be their long term relationship with each other. It was Alan who was first to get his mouth around a cock, giving Dan a very enthusiastic blow job while reaching up and stroking his nipples to enhance what he was going to be doing to him later. A few minutes later it was Dan who was sucking Alan's cock and they took turns raising their lust to new heights in preparation for Alan to gain satisfaction from deep within Dan.
Eventually Alan used his fingers to make entering Dan easier and enjoyed the anticipation of what he was about to do. They relied on what they had used on holiday, this time it was olive oil and just as Alan had smothered it over his cock and Dan had assumed the position the doorbell rang.
It suddenly dawned on Dan that it was a parcel delivery. He had expected it the day before. The thought of having to go all the way into town and queue up at the parcel pickup office filled him with dread, so he resolved to answer it. He quickly put on his dressing gown, tousled his hair and dashed down to answer the door, pretending to have just woken up and being on night shift. This left Alan, oiled up and ready to mount Dan stroking his slippery cock and urging him to hurry up.
