Because you are so small, you digest quickly in Ellie's stomach, but you and Maria are so entangle in each other and climaxing so vigorously that you are able to handle the pain...as you climax into each other, kiss each other, and moan in pleasure, you are both digested.
Your bodies fall apart as they are liquefied, and drawn into Ellie's small intestine, where they are absorbed into Ellie's body, to be distributed to her breasts.
Ellie climaxes in orgasm as she feels the two of you rubbing inside of her, then the rubbing subsides, then ELlie gives a belch.
The next morning, Ellie's breasts are noticibly larger. But you two aren't around to see them. Happily for you, you've wound up in Heaven, where you are now dressed in white robes and are able to forget all the torture that Ellie gave you. IN fact, you almost thank her for the erotic experience you couldn't have had without her...without damning yourselves, at least.
