Vibrator action

Your sister pulls her nipple from your mouth; Trish is still on top of you, fucking you hard, her breasts wobbling wildly. You see Heather opening the nightstand drawer and pulling something out. You hear a click and a buzz as she comes into view again holding a sleek white vibrator that is about seven inches long. She starts rubbing it around Trish's clit, and you can feel the vibrations through her flesh, driving you deeper into your ecstatic state. Trish groans loudly at the feeling. Heather moves it around and runs the device across your balls; you growl your pleasure at this new sensation. Then she starts rubbing it between your balls and your asshole, making your taint buzz and hum. Trish's cunt is leaking serious lubrication all over your cock and balls, and some of it is dripping between your ass cheeks and covering the plastic toy. Heather shifts the vibrator again and circles around your rosebud as Trish increases the pace on your pulsing cock.

"No, no, NO!" you shout as you feel her press the tip against your sphincter. The buzzing is driving you nuts, but you've never had anything up your ass, and the thought isn't pleasant. You clench your buttocks, but Heather just presses harder. "Oof!" you say as the tip slips into your rectum, expanding your anus forcibly. Your body is now tingling from the electrical pleasure appliance in your bowels; it's reaction denies your mind's thoughts of disgust, and you are overwhelmed by the intensity of the feelings in your ass.

Your sister starts thrusting the vibrator in and out of your butt until she finds the walnut-sized lump of your prostate gland. Your groin is out of your control as it shakes and pumps upward into Trish as she drops down; your bodies slam together pretty hard each time. In seconds, your head and cock both explode, your head splashing a dozen yellow stars in front of your eyes and your cock splashing a dozen spurts of spunk into your sister's friend's inflamed cunt. The combined sensations of your buzzing cock and the superheated jism inside Trish throws her into a frenzy of humping on your meat. She screams as she is consumed by her orgasm, jerking uncontrollably on top of you.

The plastic intruder into your ass propels you through your climax, bringing you higher than you've ever been. All thought is extinguished in your brain as you convulse wildly. Finally, Trish slumps over on your body, and she pulls herself off your member. She is breathing hard to replace the oxygen she just expended.

Heather starts moving the vibrator in and out again, and your body won't let your cock collapse. It feels amazing inside Trish's hot cunt.
