I was halfway now, and I was being nice. Going slow, still applying so much lube it was puddling beneath her. I had a feeling if her hands were free, she’d be–
As if reading my mind, Terri came off Dad’s cock enough to say, “Please free my hands,” and then she was back to sliding up and down his pole.
Dad looked at me and I shrugged. He undid one of her hands and it flew to her slit, desperately rubbing at herself.
I watched all this and was grinning when I bottomed out in her ass. I looked down in surprise and saw my pelvis resting against her cheeks, my cock completely buried in her.
“Wow girl, I’m impressed. I honestly didn’t think you’d be able to take it all. I guess you’re the bigger slut between us,” I chuckled.
“Says the girl who’s banging my ass while I blow her dad, you bitch!” Terri’s words were cut off when Dad pulled her back onto his cock.
“Stop shirking your job, slut. If my daughter says you’re the bigger slut, then I believe it. Especially with how quick you were to flash your tits at me.” Dad told me later that Terri gave him such a look just then that he almost stopped. If I hadn’t told him how much of a mask she like to wear to hide how desperately she really wanted to be used, he would have called the whole thing off.
Instead, Dad pushed into her throat, causing her to gag, but he didn’t stop.
Neither did I. I slowly began to pull out, then push back in using short strokes. I wanted to take it slow. She was already squeezing me so tight I was having to fight to not cum. Then, I remembered my newfound stamina and began to thrust in tiny strokes that quickly drove me over the edge. I couldn’t handle edging. I needed to knock this one out so I could get serious.
I could feel my hot seed starting to spill into her bowls. I roughly pumped once, twice, and a final third time, getting as deep into her as I could before holding it there. My cock twitched and spurted, unloading deep into her.
She must have felt something as she seemed to wiggle her ass slightly and moan deeply.
“Did you just cum in her ass?” my dad asked. “The look on your face tells me you did.” His grin was ear to ear as he paused and looked down at Terri. He slowly pulled his cock from her mouth, large drool stings still connecting the two as she collapsed. With her face planted on the bed, her hand never stopped between her thighs.
“Did you feel her blowing off in your butt?” My dad asked crudely.
“YeeeeeEEESSSSS!” Terri cried as her orgasm washed over her.
My dad just laughed and watched as she trembled, still impaled on my cock. “That’s one of the hottest damn things I ever saw,” his voice was almost reverent. “Wish I had a camera to record all of this,” Dad said, winking at me.
Her orgasm caused her insides to start squeezing me over and over with each wave. My cock was hyper-sensitive from my orgasm and her squeezing caused me to flinch each time. I hadn’t really started getting soft, but the new sensation made sure I was as hard as ever now.
I held off until I felt her insides start to relax at the end of her orgasm. I waited a beat and then started moving.
“What?!?” Terri screeched, looking back at me with eyes wide.
I started slowly, but this time, it was long strokes, not short ones. I pulled out halfway, then plunged back in, repeat. With each stroke, I pulled out more until I was only leaving the head in before diving back in.
Terri, on the other hand, sounded like she was in labor. Every thrust caused a deep, guttural grunt that almost sounded painful. If it weren’t for her hand starting back up on her clit, I would have been worried.
Instead, I was moving non-stop now. The entire length of my cock, save the head, was sliding in and out of her. I couldn’t take my eyes off the sight; it was so damned hot. The more I watched, the more I gave it to her until I was, honest to God, plowing her ass.
Terri had given up on her clit and was collapsed in a heap on the bed now. I was fucking the shit out of her at this point and she was just taking it like a champ. Every time I bottomed out in her she would groan, making the sluttiest sound I’d ever heard.
At one point, her eyes rolled up, and her tongue lolled out of her mouth like the girls did in hentai videos. Drool was spilling off her tongue and onto the bed. I didn’t know someone really did that. I know no one had ever fucked me enough to make me do it.
Dad just watched, mesmerized. That and I didn’t think he wanted to get near her mouth while she was in that zoned-out state.
“I’m gonna cum!” I bellowed like a steam engine. I was working hard, pounding my friend’s ass, and I started to feel winded.
“Yeeeeeees,” Terri groaned. “Please cummmmm.” She sounded exhausted.
“Oh, really slut? Do you want me to cum? Tell me where?” I ordered.
“In my butt. Just cum in my buuuuutttttt,” Terri’s voice wavered with every pounding I gave her.
My pelvis was actually sore from being so forceful. From the way Terri was acting, I was worried I might have broken her in some way. I’d never seen her so… well… broken.
Then I buried myself and groaned as my cock once again deposited my seed deep into her bowels. Her ass willingly accepted it, quivering and feeling like it was sucking it in. When I finally stopped, the room was spinning and I was exhausted.
As gently as I could, I pulled myself out of Terri. My cock make a lewd, sloppy sound as it popped out of her now gaping hole.
“Oh wow,” my dad said. When Terry had collapsed, he’d moved around to watch me plow her. Now, he was watching as my cum started to seep out of Terri’s ass. “She really made a mess back here.” He reached up and slid one finger around the rim of her asshole, making Terri twitch and moan. God my dad was dirty.
“Oh good, she’s still alive,” Dad said as an evil grin crossed his face, one I both hoped and dreaded him using on me.
Everything I was doing with my dad was opening my eyes to him. I thought I was depraved, but from what I was watching, I was still an amateur. I wondered what all this man could teach me.
Dad moved Terri’s now pliant form. He unstrapped her and moved her between where I’d collapsed on the bed, utterly exhausted, and where he was now standing.
I saw when Dad entered her. Terri’s eyes rolled up and she bit her lip. I wasn’t sure which hole he was using, but she was obviously enjoying it.
I looked up and saw Dad grinning like an idiot. He must have been in her pussy because I watched as his thumb started playing with where her ass would be.
Something hot and wet on my cock made me jump. I looked down to find Terri licking at my cock. I knew Terri was a freak, but I didn’t know it went this far. But as I watched her, in all her sluttiness, it lit something deep inside of me.
