"Your balls are so big!" you hear the red fairy say from outside. "You can do the thing now!"

"What thing?" says the blue fairy.

"The thing! You know! The thing!"

You can't see the blue fairy's face obviously but somehow you know she's rolling her eyes anyway.

"I think I know what you're talking about," she says, "now turn your ass around."

There's a pause, then you feel the flesh around you jostle slightly. It does so again, then again and again, and you can feel the swaying of the blue fairy's ballsack back and forth while she fucks the red fairy.

"Do... the thing!" you hear the red fairy say outside while panting.

"You asked for it!" the blue fairy says and you feel the chamber around you squeeze.

The pressure around you builds but not as quickly as you were expecting. You're squeezed slowly into the blue fairy's shaft and she doesn't pause in her thrusts for even a second as you make your leisurely way back up the way you came. The pressure of the shafts walls are significant but as you're pressed into the red fairy's pussy the walls squeezing down onto the shaft and by extension onto you are much more pressing. Each time the blue fairy thrusts back into the red fairy more of you is pushed into the shaft of her cock and less of you leaves the red fairy's pussy when the blue fairy pulls back for another thrust.

The red fairy's moans grow loud and wild as her pussy is stretched by the blue fairy's dick. Using your body as a penile enhancing supplement the blue fairy now sports a shaft that's as long as you are tall. After a few minutes of being used as a dildo for the couple your head is forced out of the blue fairy's cock head. Your face is rammed into the cervix of the red fairy and her cries reach a fever pitch. The walls of her vagina squeeze onto you and the blue fairy's shaft together.

The stimulation is too much for the blue fairy and you feel the pressure of her semen from behind. It pushes you forward and out of the cock, straight into the red fairy's cervix. After only a moment the pressure forces the red fairy's cervix open and you're forced into her womb. What feels like gallons of cum follows you in and you find yourself lying in a pool of it.
