Jane Cortez and her living sex toy [NSFW] (Patreon)

It all began as your average sexual encounter between a man and a woman. They admired each other's bodies, he worshipped hers, they caressed and kissed and eventually his lips came down to her wet vagina and began to kiss and lick it passionately. Jane really loved this and before long she felt so much pleasure, she instinctively brought her hand to her partner's head and gently pushed him tighter against her labia. 

At first, he believed she was going to crush his head against her tightly closed labia, but to his surprise and relief, her lips parted, and they did so widely. She is so much bigger than the average woman, her vagina opened up enough for his head to slip comfortably inside and then closed tightly around his neck (tight enough to hold him inside but not enough to cause him any harm). To add to his surprise, inside her he finds out he can breathe just fine (neither he nor she has any idea how that's possible).

Cheers
