It took me a few minutes of lying on the couch with my legs spread and Scott's cum dripping out of my cunt to come down from all the orgasms Scott had just pushed me to. I had cheated on my fiance, the sweetest man I knew, with his own father, while he slept upstairs. Not only that, but I had begged Scott to fuck me raw and fill me with his seed, something I had never let Jack, nor anyone else, do. I gathered my discarded clothes and limped off to the guest bathroom down the hall from the room Jack and I shared.

Looking in the mirror, I could hardly recognize myself. Who was this filthy, cheating slut? What kind of needy, animalistic whore lets his father-in-law use him as a cum dump sex toy?

I turned on the shower, hot as it would go. I stepped inside the steam and shut the glass door behind me. I let the hot water roll over me for a moment, over my flat chest, my wide hips, my full ass. My hand wandered to my clit, and I feverishly worked myself towards another orgasm, thinking about the memory of Scott's thick cock stretching my pussy.

I heard the door creep open. Jack entered the bathroom, wearing just his pajama pants. He blinked at me, watching my fingers rub my clit.

"Hey there," he said. "Want some company?"

"Please," I said.

He pulled his pants down, revealing his hardening cock. It wasn't as long or as thick as Scott's, but it was still a decent size. As soon as he stepped inside the shower, our hands and lips were on each other.

I moaned as he slowly circled my clit with his long fingers. He was always so gentle, taking his time to pleasure me. I pulled his mouth to mine, and our tongues met. I loved him so much, I felt it could shine out of me. But I still thought of Scott's cock, how full he made me, his seed dripping out of my pussy.

I needed to clean my thoughts of Scott. I reached for Jack's cock and began to stroke him. I heard his breath catch as I massaged his balls. I guided him to turn so his back was against the spray of water, then sank to my knees.

His cock fit in my mouth perfectly, enough to feel full without making me gag. I took my time licking it, looking up at my fiancé as the water poured down his shoulders and over the muscles of his chest.

"Yes, baby," he whispered. "You know how I like it."

I bobbed my head on his cock, massaging his balls in one hand. The feel of it was so familiar, so comforting. I felt the need building in my greedy pussy again. He grabbed my short hair, his tell that I was getting him close.

I kissed Jack's cock all over, from the base up to the tip. He tipped my chin up to look at him, then pulled me up for a kiss, his hard cock rubbing between us.

"I know you don't want to risk getting pregnant," he said, "but I need to feel you right now. I promise I'll pull out."

I thought about it for a moment. My pussy throbbed with need.

"Do it. Fuck me."

I turned around and braced my arms against the shower wall, leaning forward to better present my full ass to Jack. He carefully pushed two fingers inside me to stretch me open, which just reminded me of how it had felt to have Scott's large cock filling me.

"Mm, just give it to me," I moaned.

"Are you sure?" he asked. "I don't want to hurt you."

"I'm sure," I replied.

He slid his cock into me, pausing for a moment to allow me to adjust. Then he began rocking into me, slow, gentle, and steady. His moans matched his steady rhythm. I hoped the sound of the water was loud enough to cover the sound of his enjoyment. One of his hands stroked down my stomach to my clit, circling in time with his strokes. It didn't take long for me to reach orgasm.

As promised, Jack pulled out before he came. Instead, he slipped his cock between my ass cheeks and, in a few strokes, his seed was coating my curvy behind.

We finished washing and went to bed without dressing. Before we both fell asleep, he said, "Benji, I've been thinking."

"What about?"

"When do you think you'll be ready for us to start trying for kids?"

"We're getting married in a few weeks. Maybe I can talk to my doctor about going off my testosterone, and then after the wedding, we can revisit it."

"Okay. I love you."

"I love you, too."

I woke up the next day to the feeling of Jack coming back to bed. He wrapped an arm around me and pulled me close to his chest. I scooted my butt closer to him, and felt a large, hard cock pressing in to me. Surprised, I turned around, and saw that it was Scott who had joined me in bed.

"What are you doing here?" I asked in a panic.

"Don't you remember? You're my slut now." His hands roamed my body, massaging my back and ass. I felt desire heat up inside me.

"What about Jack?"

"He's already gone to work. You know, I heard you two in the shower last night."

My face flushed. "He came in while I was washing up."

"Did you let him cum in your pussy?" he asked.

"No, he came on my ass."

"Good. I meant it when I said your pussy belongs to me now." His fingers started to lazily circle my clit. "Are you on any birth control?"

"No, I'm not," I replied. "I'm on testosterone, but that just makes it less likely. I'll be going off it soon, though."

"I'm glad," he said. "I want you fertile."

He pulled me in to kiss me, his arms tight around my body, and I melted. Our bodies writhed against each other, as did our tongues. I could feel my pussy soaking with juices, aching for Scott's cock.

"Mmm," I moaned, as I rocked my hips into Scott's, coating his cock with my damp need, "I can't. Not in the bed we share."

"Tell me to stop, then." He inserted three rough fingers into my pussy, making me gasp. "But I don't think you will." He started fucking his fingers into me. All I could do was moan. He was getting me close again. I grabbed his shoulders tight. "I think you know exactly whose slut you are."

My groans grew desperate as I neared my peak. Suddenly, he pulled his fingers out. I whined at the absence.

"I think you're going to put my cock in your pussy yourself," he said. "And then I think you're going to fuck yourself on my cock until I fill you with my load." He rolled onto his back and took his cock in his hand. He stroked himself, pumping his hand around that beautiful, hard cock. I knew then that I'd never say no to him. I really was his cumdump slut.

Just as he predicted, I mounted my future father-in-law. I ground my pussy onto his hard cock, then guided it inside me. Once again, he stretched me open. I stilled for a moment to feel it deep inside me.

"Good boy," Scott murmured. "Good slut."

I began bouncing my hips against his, feeling his cock rock in and out of my pussy. In moments, I was orgasming.

"Good, tell me how you feel about my cock." His voice was low and deep.

"I love it, I love your cock, Daddy."

"Tell me whose slut you are," he said.

"I'm yours, all yours," I moaned. I bounced faster on his cock, racing towards another orgasm. His hands possessively grabbed the meat of my ass.

"Tell me who this pussy belongs to." His fingers dug into my hips.

"It's yours, yours to fuck full of cum." My arms started to tingle with numbness from all the pleasure. "I'm never going to say no to this cock. You can have me whenever you want me."

"Good little slut," he said. "This womb is mine too. I'm going to fill you with my seed until it takes. You can keep up appearances and let Jack raise them, but we'll both know who bred you." At those traitorous words, my pussy came hard. My arms went numb and I collapsed on Scott's chest.

Scott gripped my hips tight against him and hammered into my pussy, fast and hard. My body was set alight on a chain of orgasms. Finally, Scott locked his arms around me as his seed erupted inside me.

We lay there for a moment in the bed that Jack and I shared. I didn't want to move, not if it could mean wasting even a drop of Scott's cum. I wondered if I was already pregnant with his child.

"I meant it, about knocking you up," he said. "I want you off that testosterone. Start tracking your cycle on one of those apps, and share access with me. I want to know when you're ovulating. Do you understand?"

"Yes, Daddy," I said.
