"Watching You Watching Me" by Gregarious (gregarious@poboxes.com). The woman moves from Texas to Boston to be with her lover, and she finds the winter to be a real burden. Then one day he comes home with tickets to Costa Rica. Anything would be better than two more weeks of gray snow, but the delights of Central America are amplified by the presence of another couple. First the woman shows off her amorous abilities on the plane in the presence of the other couple. Then she discovers that they are in the same resort, and she spies on them while they make love. All this leads to hot sex with her own lover. It's very sexy stuff!
