Seth positioned himself to the right place, going as far as rubbing her pussy lips with his rod and since he could already feel the excitement coming from the Elf Queen, he decided that he didn't want to make her keep waiting.
Without any more delay, he pushed his hip forward, until he connected his body together with hers, instantly feeling he had entered the paradise. But he didn't stop only there. Seth kept pushing slowly but steadly, till he felt her internal folds were completely accommodating the new visitant they were receiving.
"Ahn... I can never get tired of this." Arwen closed her eyes and started to enjoy that sensation.
Ever since she had done it with Seth for the first time, she felt he was able to complete her; to fill the gap she had from a soulmate she never had. And that situation was the illustration of what her thoughts represented.
They were connecting together in body and soul, enjoying each other's presence and company.
