"Roomies" is particularly good but it always irritates me, when you've got performers for whom it is "supposed" to be their first time with their buddy and one is cut and the other not, that there is no mention of it. Surely if you're stroking/sucking a mate with a foreskin for the first time (even if you knew before that he was uncut) you would pass comment on technique and ask if you were doing it to his satisfaction? The same for the circumcised guy (in fact, especially when a cut guy is being stroked by an uncut one - because you can't be as rough with his more delicate cockhead).
