As best you can

Carrie's comically coated form looms above you as she pets your head expectantly. Her grasp has become far more gentle, to the extent that you might have even entertained the idea of shuffling away had she not had your package pinned to the floor in a vice.

You waste little time testing the limits of her newfound cruelty and instead begin leaning towards the monstrous helping of "icing" your sister left behind on your beloved.

The first thing you notice was the smell. Distracted by your own rapture and the ensuing pain and confusion you didn't catch it before. But being inches away and with eating her cum in mind you are suddenly awash in your sister's scent. While your own cum smells something between chlorine or fresh dough, with hers there is a bit more to it. The sweetness is far more pronounced and there's almost a hint of spice in there. The total effect being that it gives off something like Hawaiian bread or fresh cinnamon rolls.

Secondly, there is just an insane quantity of the stuff. Depending on the arrangement of the ropes and pools slathering Carrie, some areas seem to have as much as an inch thick gloss, and she's more coated than not. This combined with your proximity makes the effect overwhelming.
You almost pass out just by getting this close to the source of the sweet clean scent.

Regardless of the uncomfortably pleasant sensation of just being near her decree, you keep inching forward, feeling the unnaturally powerful heat of the stuff waft off of you girlfriends lacquered body.

Your lips meet the messy sheet of cum on her thigh and you attempt to suck the goo down as efficiently as you can. But in addition to the fact that your initial attempt fails, the dense matrix of supernatural seed proving too heavy to merely sip, you get your first taste of your sister's virility, and it's just too much.

You begin cumming on the spot. Your denied little dicklet punishes itself violently against its prison. Carrie's toes then immediately tighten around your cock and balls, pinching beneath them in an effort to stave off any more of your disobedient discharge.

This time Carrie can't stifle her laughter, the sadistic melody pelts your ears as you neglected little nads are pinched off by her ruthless embrace.
"I know from experience just how good her cum tastes baby, so I'm not going to punish you any further, but _do _try to keep yourself together just a little bit, OK?" She taunts. "I'm going to relax now, finish cumming and then get back to work."

You reel back from the cinching and try to focus as your sister's ambrosia finishes frying your senses for the very first time. Your now unpinched nub leaks its weeping need violently against the floor as Carrie gently pets your head in knowing consolation.

Totally ignorant of whatever she said you lean back towards her christened thigh, biting through the dense warm cream and sucking the molten cock custard down with **** need.

As you begin the daunting task of consuming what must be pounds of your sister's cum off of your formerly doting girlfriend, she begins her tale...
