17, my high school girl friend's parents were out of town and her grandmother was house sitting, said no one could come over, but I did anyways (she was old and went to bed earlier) so the gf snuck me in the basement and we did it on her fold out bed/sofa down there. Fun times
Lilian is against bikini photo shoots, isn't she? And she also never did anything other than "plain clothes" photo shoots. No lingerie or any of the sort. Maybe that's why she's always left out of it. I don't know, just my thought.
