The Dorcas Society

At the close of four and a half months' hard work, the ladies of a certain Dorcas Society were so delighted with the completion of a beautiful silk patchwork quilt for the dear curate that everybody kissed everybody else, except, of course, the bashful young man himself, who only kissed his sisters, whom he had called for, to escort home. 

There were just a gross of osculations altogether. 
How much longer would the ladies have taken over their needlework task if the sisters of the curate referred to had played lawn tennis instead of attending the meetings? 

Of course we must assume that the ladies attended regularly, and I am sure that they all worked equally well. 
A mutual kiss here counts as two osculations
