Odysseus has recently returned from his long journey home from Troy, having been drafted for war 20 years earlier

Athena, being Odysseus' ex-mentor and friend, decided to help him out and ask Helios to make the night longer

now Odysseus and Penelope had a long night at their disposal, during which they rekindled the passion they had in the past - well, and basically, quenched their desire that had been accumulating for twenty years

meanwhile, in the next room, their poor son Telemachus is burning with shame, traumatized enough by the loud moans. they were very embarrassing for you too - you were both awake, and your husband was... rather worked up about it

"i swear, one more 'oh, Odysseus, yes!' and i'll go nuts."
