You think two women going to the beach would make them lesbian? I have no data to back this up, but I would say the majority of woman going to the beach together are straight.
That’s why I ask how did the woman know they were lesbians? Can she spot a lesbian? Maybe there’s a secret sign the women didn’t use.
Same as VerySad - point is how did she know? And you’d think she might possibly assume they are homo, being she is 1 and might like the same situation.
