Nothing to be sorry for, I appreciate the hype and am always happy to answer questions! 🙂
1. You can't hook up with Tomas yet, but you can start moving things in that direction in this new update.
2. I'm not sure what you mean by this question, unfortunately.
3. Yes, more Grind'm scenarios are on the way! I'm working on the second one now, actually, which features NC17's twin, Trevor. I spent the past few days creating images for his profile and wrote the intro/foreplay section, and I think it's turning out great.
The third Grind'm guy will be Parker, the theatrical guy in the hat at the frat party. That scenario will be released a few updates from now. I don't know who will get a scenario beyond that since the guys are chosen by vote on Patreon, and I haven't done the fourth vote yet.
