Rachel reached over into the box and picked out two chocolates: a dark pussy and dark tonge piece. Pressing her finger onto the base of the tongue piece, she melted some of the chocolate and attached it to the dark pussy chocolate and ate it.
Rachel moaned in extacy as a small tongue tickled the inside of her pussy. She grabbed the same two chocolates and repeated the process, making her cunt and the tongue in it grow.
"Hey Mark," Rachel said, "close your eyes" she said as she fed him another dark chocolate penis. Mark opened his eyes to see an his cock enlarge again, to a whole foot long! Mark got really hard at the sight of his giant member, and it nearly tripled in length. "Now let me blow you" Rachel said as she stuck out her second tongue, Mark almost looked surprised, but he backed up so that Rachel could get his giant dick inside of her. Both Rachel and Mark moaned in pleasure as Rachel's tongue blowed Mark's dick, and his dick jostling around in her pussy. Rachel got a white chocolate pussy and a dark chocolate tonge this time, melted them together and ate them, moaning in pleasure as her tongue expanded to wrap halfway around Mark's giant cock, and as her pussy tightened down on his dick, sending shivers up her spine and into her dick nipples, making them throb harder. Rachel threw her head back and gave a loud moan as Mark almost pulled out from all the pleasure he was recieving from the giant blowjob.
When Mark orgasmed, his cum shot out at such a force that his cock dislodged from Rachel's pussy, at the exact same time Rachel climaxed as well. Wads of cum spat out of Mark's 3 foot dick and hit the wall with enough force to crack the plaster. Rachel screamed with lust as her juices avalanched out of her cunt. Both of their orgasms lasted several minutes. Afterwards, they were out of breath and ready for more.
