Yes

Before snapping her out, you decide to give her one last trigger.

"Whenever I kiss you, you will kiss me back and become very horny. Now you will snap out of this trance, Ro", you tell her, and she immediately did so, appearing slightly dazed. You then come closer to her give her another kiss, working your tongue into her mouth before she kisses back, wrestling with her tongue but failing to push you out.

When you pull back from the kiss, Ro's eyes are filled with lust, proving your kiss trigger worked perfectly. Quickly, you take your pants off, and the sight of your dick activates her other trigger, sending her into a fit of lust, grabbing your dick and massaging it while playing with her breasts.

"That's it, Ro, suck my dick right now", you order her, and she quickly obeyed, getting on her knees and taking your dick in her mouth. It felt fantastic to have Ro's mouth around your dick, to have her massaging your balls and licking your shaft as she gives you pleasure.

She began to bob her head as you groan in pleasure, silently thanking X for giving you this ability, and wondering how many of your sister's friends you will be able to claim as your own thanks to this ability. After a while of Ro's admittedly skillful blowjob, you begin to reach the edge, and decide you want to see Ro's face covered by you cum.

Acting on that, at the last second you pull out of her mouth, covering her face with your white liquid, going as high up as her dull red hair, where it greatly contrasts. You put your pants back on, panting, and lay on your bed, looking at the lovely sight of Ro, who is still on her knees, slowly clearing the cum from her face. Looking at her, you wonder what else you could do with her. You also wonder if you could do something else with Alice, remembering what X said about his mother and sister working for some agency to make extra money. That could be very useful.
