Surprisingly well

“Hey Ash. Just got back from the bar.” Amy continues to gag you with her cock as she explains herself. “Was planning to pass out in bed only to find my little sis sleeping with her boy toy”. Amy enunciates the words “Boy” and “Toy” and punctuates them by jamming her dick further down your throat as she speaks each word.

“May I ask why you have your cock in his mouth Amy?” asks Ashley. “Oh that? Well I was just feeling a bit horny after being out partying all night. I was actually thinking about bringing a guy home since Mom and Dad are away, but I figured I shouldn’t set a bad example for my little sis. So much for that I guess”.

“By the way…” Amy asks in an inquiring tone. “Is that a chastity belt he’s wearing?”

As her conversation with Ashley continues, Amy finally removes her magnificent…I mean unwanted…cock from your mouth.

“Oh that. Yeah I bought that for Doug. I was concerned about his ability to stay faithful to me, so we decided this was the best option” explains Ashley matter-of-factly.

“Well it's certainly effective, when I first saw him sleeping face-down ass-up I was planning on waking him up with a good fucking, but I had to settle for second best, if you catch my drift.”

“What the fuck Amy?” you say. Neither Amy nor Ashley pay you any attention.

“Well I have the key right here” Ashley states, motioning to the chain around her neck. “I was more worried about one of those big-dicked bitches at school fucking him behind my back and hurting him. But we are sisters after all” Ashley again takes off the chain and reaches over to unlock the waistband of your chastity belt. She loosens the pink knob and then places the key back around her neck.

Amy once again curls her fingers under the waistband and goes to yank the device off of you. Possibly unaware of the fact that the device is connected to a sizable butt plug, Amy is not gentle and the sudden withdrawal causes you to gasp and shudder. The butt plug is removed, along with the rest of the device, and audible plop is heard by both girls.

Hearing the telltale plop, Amy chuckles and flips you onto your stomach, her athletic body able to easily re-position you on a whim. Amy spreads your cheeks and says “Look at that Ash, his pussy is wide open for me”. You can’t see her moving behind you but you are sure that Amy is grinning madly.

“Grab that bottle of lube from the top drawer” Amy says to Ashley who then reaches over to the bedside table.

“Oh what’s that?” says Amy. “Oh that? That's the cock cage that goes with his chastity belt” replies Ashley.

“Oh right. Don’t you think he should be wearing it?” asks Amy. “Well I forgot to put it back before we went to sleep” explains Amy.

“You really should put it on Ash. You know it’s not healthy for a boy to have his dick hard all the time time. Sooner or later he has to learn that sex is for your pleasure, not his”. Amy speaks to Ashley in a sisterly but somewhat scolding tone.

“Not healthy? What are you talking about?” you ask, puzzled by what Amy is saying.

“Well you can’t put the cage on when he's hard anyways” says Amy.
