May i suggest instead of the latest glam blow job scene something a little more hardcore. At least put a good sized plug up her ass or have her placed with a fucking machine taking her ass at least while blowing guys.
For me a blowjob only scene would go as follows. Scene opens we see nice chesty girl tied to floor with a long dildo gag down her throat . A 12 inch dildo can be seen working in and out of her ass we also see wires from a electro plug hanging from her pussy. Many dudes enter for their bj, they remove the dildo mouth gag and play with the speed and depth of plug fucking her ass. after a while they change the fucking machine dildo out for a thicker longer one. If they are not happy with how hard she sucks they shock her pussy with the electro plug she swallows all their cun and is left still on the floor being ass fuxked by the machine for the entire duration of the scene.
