She keeps growing

By: GiantessLover

Your sister continued her massive growth spurt and in time she was 50 feet tall. Despite her using you everyday for her own pleasure, you found time for a relationship with a girl named Alison.

Alison was a girl any guy would kill to be with. She was incredibly tall at 6'3, standing 3 inches taller than you and her breasts were a massive 34 K which even at her massive 50 foot height, your sister was insanely jealous of due to only being a C cup herself. Kim also kinda had a crush on Alison for the longest time. Before her growth spurt she was going to ask out Alison due to hearing how Alison was into both guys and girls.

You were in your bedroom, making love to Alison while Kim watched from outside unbeknownst to the two of you. Stroking her massive cock, with her other hand over her mouth to hold back her moans. Watching as Alison rode you on top, her massive tits bouncing and wobbling all over the place. Alison looked down and kisses you, and began to tell you her wishes.

"Oh god Will, I wish i was bigger, like your sister Kim. No don't look at me like that mmmm I would be so kind to you. I would protect you. Hold you close while you explored my huge body. I would be your goddess, your protector, your massive ohhhhh lover!"

As she climaxes and you climax inside her, your window bursts open with the head of Kim's massive cock. She begins to unload a massive torrent of her splooge all over you and Alison. Flooding your room. Pushing further in, the head of her cock pins you down under it and the spray gets into Alison's mouth forcing her to swallow a lot of it or she'll drown. Kim pulls back and smiles, glad she ruined your date as she returns to the barn.
