That she wants to make sweet music with you.

"You made me feel much better. I could almost sing. Don’t worry though. I won’t put you through that. Buuuut I could stand to hear you sing a few bars."

Your eyes must have shown true confusion as you sucked on her cock head because she started giggling and she bent down and grabbed your ass. Her icy grip causes you to make a loud high yip sound that echoed in the chamber. A sound you didn’t know you could make. She lifts you effortlessly by your behind. Helping as best as you can you straddle her hips and wrap your arms around her. Normally this would be really romantic but it’s like hugging a bronze statue in the middle of a blizzard. Your nerves are screaming to let go but before you could even muster the plan of action a very cold intrude knocks on your shivering backdoor.

"I can’t wait to find out if you’re a soprano or an alto."

Regina jerks her hips upward and your ring surrenders to the frozen invader.

“OH AH” you scream in a high pitched voice.

"Oh, an alto! Give me a good whole note hot stuff!"

She gives your neck a sharp bite and then slams you half way down her rod.

“AHHHHHHHHHHHHHHHHHHHHHH”

You never knew you could carry a tune but Regina is having a surprising effect on you, might have something to do with the ice log making its way up your colon.

"I love your voice. Let’s make some music!"

Regina lifts and then drops you down on her sex. You bottom out and her balls slap your ass cheeks. Your alto voice lets out a small wincing note. Regina holds you tight. Her head next to yours. Her smooth slick freezing body triggers every nerve on your skin. She starts humping you. Only half of her dick coming out of you with every thrust. Each time she pushes in you let out a small note. This makes her want to change her rhythm every few seconds.

“Ha”

*Smack*

“Ha”

*Smack*

*Smack*

"HAAAA"

She’s pegging you like a set of bagpipes.

"Tell me you want my dick."

“I want you-”

"No, sing it to me!"

The cold is draining your energy, you can barely feel your ring anymore but you’re sure it’d be gaping if she wasn’t fucking the strength out of you.

You muster a minor arpeggio, “Please fuck me with that ice cannon!”

Regina let’s go of you and her cock keeps you mostly suspended in mid-air. As you lean back she jerks her cock so you bounce a bit. Smiling ear to ear she lifts your left leg and you feel your guts twisting around her solid gut buster. She’s rotating you on her dick like a hog on a spit. Belly now facing the ground Regina walks you over to the arm of the couch and folds you over. Your ass still plugged down to her balls. The angle is making her dick now press your spine into a straight line. You try and arch your back to help but it barely matters.

Regina starts plowing you again. The couch is actually helping you get feeling back in your face and chest but anything below your waste is an icy desert of sensation. You feel your guts shifting with every heavy drop of her womanhood. The only saving grace is not feeling the loud smacks her balls are generating from dominating your insignificant testicles.

Singing to her seemed to please her and turn her on more so you figured maybe it’d help.

“Let it go!”

"Are you serious!?"

“Let it gooooo!”

"Oh, you must have a **** wish that is terrible!"

“Can’t hold it back anymore”

"You little trollop! Ugh, fuck gonna have to break you in a bit harder now."

Regina’s cock expands by nearly double and your joke turns into a bunch of gibberish. Her thrusts are becoming brutal. She seems to be trying to break your back with every thrust. Sometimes driving deep and holding while pressing her column up and down to further warp your cum shute. Now she is singing with every thrust. Her voice is quite good. You can’t help but shiver with every bounce of her balls on your behind. Undoubtedly driving her on.

"Ugh fuck babe guess that was pretty appropriate! I’m about drop some girl juice down that hot ass of yours."

“Please fill my ass up Regina, I want you to blow that fucking hot load in me!”

"aaaAAAAHHHHH"

She drives deep and stays there. Your guts feel a huge expansion and then warmth. Finally, you feel your body temperature rising. Your stomach is expanding too. In little stages, looking down you see the pressure building and it drives you over the edge. Your comparably small dick spurts hard. You feel your ring pointlessly convulse on her still glacier hard dick. This causes Regina to shudder and you feel the base of her cock expand upward and as it reaches the tip your belly massively expands outward. You’re sweating now, it’s almost worse since Regina’s skin is still ice cold causing it to evaporate immediately. You're stuck between overheating and hypothermia. Regina pulls out and your guts start pushing her batter out. It’s not as viscus as the other girls it’s actually slowly sliding down your back like melted butter creme. Regina saunters over and turns your head towards her sex. She waits for you to open and accept her pride and joy. You oblige and get a solid helping of the leftover sweet jizz she’s implanted in you. It’s a real treat.

The intercom clicks on.

"Great work you too, I was happy to see you both restrain yourselves from the Ice puns. Get some rest and we'll see you in the morning."

And so, the test ends and you make your way back to your rooms.

You got the "Cold sore" ending with Regina.
