Final Fantasy 7 - A Marathon's Purpose (F Dom/M, Excessive size, Futa/M)

I've had this FF7 story sitting on my hard drive for an excessively long time. It is a two parter and, as part one contains no futa, didn't want to release it. I'd really like to finish typing part two over the next couple days. My hope is if I release part one it will be the motivation to finish it.

This is female strapon on male. The portrayed size of the strapon is beyond any reasonable expectation and no attempt is made at explaining how it is feasible. M/F is referenced at a few points. Just to warn people, it's fairly short and this is only part one of two.

Cloud nervously walked around the house. He was on the lookout for Tifa. Normally he would be more than happy to see her, but today was getting a little tricky. Fifteen hours ago she had started her “game”. That was when she had grabbed him, bent him over a table, and fucked his ass till she was swallowing a load of cum. He had been very pleased with the surprise, and also when she had done it an hour later on the stairs. That time her dildo had been even larger, but he was quite capable of taking it. It wasn't the first time he had been fucked by Tifa and she had chosen a much smaller dildo than she normally used. An hour later when she had fucked him on the bed with an even larger plastic cock he began to get suspicious. When another hour had passed and she was fucking him in the shower, again with a larger cock, he was downright worried about what was going to happen to him.

He'd known something was up when she had sent the kids away for a week long field trip (that only began yesterday), but he certainly didn't expect anything like this.

After the fifth time he had asked what she was up to. She had stated that she was going to fuck him every hour for a full day. He had asked why, she hadn't answered until after the ninth time. She had only coyly mentioned that he was going to be glad she had given him such a thorough stretching.

Every time she fucked him until he came. Sometimes she drank it, sometimes he had to. Sometimes she took it on her face or breasts. Not once had she actually ridden his cock. He hadn't even touched her pussy. Normally when she was in a dominant mood like this he'd have spent a considerable amount of time eating her cunt. It seemed like she was getting immense pleasure from just fucking him again and again.

For awhile it was exciting, really exciting, but he did not know if he was going to survive. He had guessed she had started with a four inch dildo. At first she had added an inch every time she fucked him. That had gone on for the first four hours until she was fucking him with an eight inch dildo. He was familiar with that size as it was what she normally used when she wanted to take his ass. She had stopped there, or at least he thought she had at first. Apparently, she had just switched to half inches. Last time he had seen her the cock was massive. If he was
