I've published one more gladiatrix chapter since you posted this, and I have one more gladiatrix chapter that just needs proofreading. As for smothering, foot smothering's not really my bag, but there's no shortage of  mothering in this series--if you're into breast smothering, check out the chapter entitled 'Kim,' which has plenty of that. There's some smaller-scale breast smother in the chapter 'The Great Coliseum,' although you may have already read that. And there's vaginal smother in the chapter entitled 'Julia,' as well as the still-to-be-published gladiator chapter. There's also tons (literally and figuratively) of breast smothering in my other story, Roman Hospitality, which is set in the same world as Pax Romana. Hopefully that answers your question!
