i think that's film13's best strength. his erotic imagination is top tier. with today's resources, anyone can animate a blowjob or a dick going in a pussy but for example, how many have animated a scene where
1) the girl jerks the guy to the point of explosion (quite a few)
+ 2) takes 1 shot on her face before shoving it balls deep into her throat (surprisingly very little artists have done 1+2 already)
+ 3) transparent x-ray where it shows the guy blasting off down her throat while she gives him the full eye contact (is there anyone besides film13 that has done 1+2+3?)
+ 4) followed by the tongue out, full frontal deepthroat (pretty sure this is just film13 now)
heck, i'd even say mitsuki's thighjob is toptier. i'm pretty sure i haven't seen such a context+ending before either. in an overly saturated erotica industry, film13 still produces novelty
those small details he adds like how she puckers her lips or shoved her face into his crotch or as macboi mentioned, the context where the woman literally ditches her date just to take his load in her pussy. that's 'eroticism' imo
