She could have indeed wound up with someone a lot worse; "awful", "creepy", and "crusty" easily some good descriptions... "Old", though? Age-wise, sure, physically, probably not so much. Once a troll became an adult, that was it. No old, wrinkly creeps among them; once grown up, they would be that way til death, whether the human definition of middle aged to several thousands of years (or in the Empress' case, tens of 'em, compounded by agelessness). Ugly, on the other hand... plenty of those among even the "beautiful" elite.

Unless something bad happened to Vriska, she'd outlive Umi for several of her lifetimes... well, if she lived to the usual human median, anyway, depending on how things went, said lifetime might be over in a few days, if that. That was the future, though, and for the present, what was happening now would continue. Her biting and nibbling doesn't stop, the troll girl adding Umi's shoulders and collarbone to the collecting spots of her hickeys.

Her fingers continue pounding in and out, continuing to give lewd, squelching sounds to be companions to the human girl's vocalizations and breaths as well as the sounds her own mouth makes against Umi's flesh. That mouth moves on to catch the bluenette's ear in its grasp, Vriska nibbling and tugging at it roughly before letting go. She adds another yank to that blue hair and gives another shoulder bite, and this time, it's to draw out some red.
