There's a possible gangbang scene in the town, but that's the only multi-person scene I've come across
There's also group sex if you're a cheerleader servicing the football team; swim team has threesomes; if you're in a polycule and have subs you can invite them and they'll all sleep with you; and at River Rat you can end up servicing a whole table. Those are the other scenarios besides the one in town that I can think of off the top of my head.
