Biting Them!

You notice her thinking about something deeply for a while before she smiles. "Oh God" you think, " What has she thought of now?"

She lays down on the floor inbetween your legs in 'the pose', on her stomach with her feet behind her head. She grabs your swollen nuts without much care before licking her lips. She sizes them up before shrugging.

Without warning she shoves your eggs into her mouth. She has to push a fair amount of your nutmeat further into her mouth with her hands due to their size, though she eventually has both of them crammed in there.

You watch her face wistfully as she sucks and slurps on them for a little while. The pain starts to fade away and be replaced by pleasure as you think about how cute she looks with her cheeks puffed up full with your balls, the warm, wet pressure on them feeling better by the second. You peek around her to look at her cute ass and soft soles, and feel yourself somehow starting to get hard despite the **** your nuts have just been through.

The entire time this is happening your sister is lost in a ball-centric trance, sucking on your jewels and prodding them with her tongue which never seems to bother you. It is only when she feels your dick start to grow barely even an inch from her face that she snaps out of it and realizes what she had meant to do when she started this.

Startled by the growing thing, she instinctively chomps down on your poor balls, crunching them between her molars. Given the size of your balls the **** is spread out evenly enough to where there isn't much fear in her breaking skin, but that does little to ease the pain.

You yelp out in pain and fear and sit up fully, trying to scooch away from her but her grip is too strong. Your balls are in her mouth and unless she *wants* to let them go, you can't stop her.

You hold her face softly with one hand, fighting to keep the strength to do even that, before whimpering a "please...."

She scrunches her face up as if to pout but being unable, while bearing down on your balls even harder, effectively chewing them now. The longer she continues the less solid your babymakers become, eventually becoming nothing but mush.

As you slowly fade into unconsciousness, you feel her squishing the last chunks of nut meat with her fingers before letting the pulped sack fall with a squishy sound onto the tiles below, and as your rapidly deflating dick lets out one last pitiful orgasm she plucks up a bead of it with her finger before sucking it off and saying,

"Nut butter, freshly squeezed.... it actually tastes really good! Nothing like normal cum. Maybe I should market this..."
