The girl gets an incredible orgasm from the vibrator

She sprawled out like a meat doll for an anatomy class. A silver plug is stuck in her ass, tight, to the point of creaking, squeezing her sphincter in sweet torment. Fingers are working over her smooth-shaven pussy, spreading the swollen, wet lips — they’re engorged with blood like overripe plums, ready to burst. Her clit twitches under the fingertip, and from her hole it oozes, trickling down her perineum toward the plug. All of this is just the anticipation of a short, wet explosion, after which only a sticky stain and trembling legs will remain.
