Siri and Lumi bangs with lots of rimming and tribbing

Description: Lumi offers Siri hand! Since Lumi knows exactly what Siri is going through, Siri wouldn't have to explain anything to her and Lumi would be able to offer Siri the safe, non-penetrative pleasure she so desires. Siri's a bit taken aback at first, but the idea is simply too tempting to resist.
