It was happening again, you felt the familiar stiffening of your cock
in your shorts. That urgent throbbing and pumping through your shaft
and balls only meant one thing: you had to cum and
you had to cum quickly. The longer you failed to empty your seed, the
more it built up and the more...
life-threatening it became.
You ran to your sister's room, where she lay sleeping. As she lazily
shifted in the covers, mumbling in response to your calls for emergency,
her breast slipped out of her shirt. That brief
glimpse of her nipple sent a whole new flood of pressure to your cock.
You
had to wake her up, you
had to convince her to help you... no matter how wrong it was.
Annoyed that your emergency erection roused her from her beauty
sleep, your sister remained unconvinced of the seriousness of the
circumstances. Both of her bare breasts swayed outside of her
shirt now, completely exposed. She didn't seem to notice, as you
bombarded her with pleas to help relieve you of the pressure.
