This is a GREAT photo! Yes...she is delightfully amateur! And, yes...she has lovely, big, natural breasts!
But, what really catches my eye...she is pretty convincingly enjoying her pleasure-session...clit-fingering hand in her panties, while sweetly tweaking her nipple with the other...eyes closed and head thrown back...enjoying her self-induced orgasm!
And, as a delicious bonus...look at the way those pretty, opaque white, lace-top, thigh-high stockings accentuate the luscious "thickness" of her long, beautifully shaped legs! (She easily qualifies for the Thick Thighs Save Lives thread, too!) Mmmm...she is exquisite!
