When it comes right down to it, Mahiru would rather be sucking on some cock than anything else. Sucking on his balls, licking them and rolling them around in her mouth. Teasing his asshole, then going back to sucking down each ball one at a time. Finally she licks his ass with a certain ferocity, which makes his dick as hard as it can get. So she has to stick it all the way down her throat. Working it as hard as she can so she can get a mouthful of cum. And she is so proud that she spits it out into her hand to show her prize.
