In bad weather, the beach sometimes becomes almost deserted, and among the few people left, it's easier to tell if someone is interested in you. When Fabiola pointed out that there was a very mature man staring at our asses, I turned to look at him, then replied that he was definitely staring at hers, but I couldn't convince her that the man didn't want us both. Fabiola looked around and, after realizing that none of the few people on the beach were looking at us, reached out and moved my swimsuit so that the man, almost seventy years old, could get a good look at my anus. Before I could say anything, she moved her hand and did the same with her swimsuit, exposing her tender bud of flesh to the man as well. Seeing me look embarrassed, she started laughing heartily, then turned to cast a mischievous glance in the man's direction, who, however, had been called back by his wife, and had returned to his umbrella. An hour later, while I was in the shower, I found myself in front of that completely naked man, who, stroking his sizeable cock, complimented Fabiola's beauty and my femininity. When he approached me, I thought he wanted to touch me, but instead, in a low voice, he told me he was throwing a "special" party at his villa and that he and his wife would appreciate me and Fabiola's presence. Before I accepted the invitation, he warned me that almost all of the guests would be very mature, and therefore we shouldn't expect models with perfect bodies, but normal people with bodies appropriate for their age. When I told him we loved mature people, his face lit up, and he suggested I join our wives for introductions. We immediately hit it off, and we agreed on the party.
