The scene begins with Anna on her back, knees up and feet on the floor, her vagina already pried wide open by the speculum, her glistening cervix staring back at you like a moist pink eye at the bottom pink tube, its gaze unwavering. Out comes the vibrator, pressed to her clit, as Anna twitches and writhes, vagina clenching on the resisting speculum. The whole time her stretched open hole is aimed right at us - enjoy the view! But mere plastic is no match for the strength of this girl's cunt muscles when she cums, and the hinge on the speculum snaps, still holding her open a little. After the spasms subside, you can see that her cervix is submerged in her own milky white juices.
