Unpause them and watch them pull each other's faces into their cunts to ride out the orgasm. Repeat this process, but arrange them in different lesbian positions each time, essentially giving them continuous rolling orgasms throughout. Do this so that from their perspective, they are having a huge sapphic orgasm for about fifteen straight minutes, waves of pleasure constantly washing over and into them as they suddenly find themselves in new positions they wouldn't have dared try without your assistance, eventually, let their orgasms die down.
After they're good and relaxed, freeze time and bring them back to the spot where you found them, and rub some breathable heavy aphrodesiac on their upper lip mixed with a hint of the other girl's pussy juices, and watch as they wake up suddenly, confused, thoroughly cum-drunk, and somehow, wanting more. They will spend the rest of the vacation trying to replicate this crazy, intense "dream", unaware that they'll never experience that pleasure again without your help.
For extra lewd, do this with Kasumi x Ayane, or Helena x Kokoro for the incest angle.
