Blowjobs are among the first skills that slutty Karryn will aquire. The guards will use her mouth as soon as her cock and mouth desires reach required levels. Just practice with them on daily basis.well BJS are the most dificult sex skill to Acquire since most of the prisoners go for the typical only/vag/anal/groping/so best way it will be slimes as someone mentioned earlier to you they practically go for anak/bj/+vaginal if u let'em..that's the fastest way,anywhere else is pure RNG...u may be lucky with orcs if they have lizardmen with them when they go for titjobs lizards go for bjs + vaginal
And then the defeat lv 1 scene is a blowbang.... Just let her lose several times and there will be a row of cocks in front of her face waiting to be sucked off.
