Yes, I don't want to get found out like this either!

"Okay Chloe I hold your word to it later! I won't let you get away with any excuses. I will fuck this ass until you are the anal world champion." I say exaggerating for comic effect and it works as she laughs out loud.

"Haha wow very ambitious of you! I only wished to get some experienced." She winks and throws out her tongue at me.

"That's just to show how lucky you are to have such a good friend." I wink back "But now I have to finish this!" I grab a hold of her hips, prefect handlebars and then pull her back against my cock. Sinking deep inside her again.

Seeing her expression shit as I do this. Her eyes getting wide for along with her mouth which was about to let out a "Ouch" but it was inaudible as she didn't want to whine. Only to transfer into a contorted face, girthing her teeth. Clearly still struggling with my size, which is always a pleasure to watch.

Before giving her time to get used to it or comment. I pull right out and thrust my hips forward holding her in place by the hips, only to repeat fucking her quite rapidly in her super tight hole. Her eyes one again open wide as she moans out with each thrust "Ah ah ah... My ass... Ah oh ah ow..."

Watching how my dick goes in and out of her ass is amazing! It's so impressive the way my log just vanish into her depth. "Fuck Chloe I love your ass! I let go of her hip with a hand not needing to hold her in place any more and slaps her ass holding it there grabbing it hard. Such a good spankable ass, I've wanted to grope and spank it for so long.

I look up and see close actually look up at me head resting against the mattress, her hands holding the sheets but to too hard. Pumping away I ask between my grunts "Oh ah Chloe oh how are you doing?"

"I... I'm fine ow..." She struggles to get out. "... I think my ass have gone numb, haha..." She tries to laugh. "In a good way thouuuugh... I can still feel you so deep inside me." I smile at her and pushes harder making sure to give her every last inch I got. Crotch smacking against her ass, making her moan even louder. "Feel this then!" I say as I start to unleash my seed deep in her bowls.

She moans along with it all "Aaaaaah aaah aaaaah." I don't pull back only leaving it hilt deep and pushes against her buns, **** to get deeper. Both my hands stretches her buttocks apart seeing her asshole still tightly crush down on my cock, milking it for all it's worth. With my last splurge of cum I let out a sigh "Fuck.... That was good..." I slowly pull back out of her ass. Just looking at the slightly gaping hole return to it's normal size. Giving it one last slap before I let go and collapse in the bed next to her on my back. She slides forward on her stomach.

I break the ice after we've rested for a good minute by once again slapping her ass. Holding onto it giving it a couple of squeezes before just letting my hand rest on it. That made sure to wake her up and she looks at me after the initial shock and smiles. "Wow that was some damn good sex, probably the best I've ever had." I tell her.

Her smile fades away as she looks at me like she can't believe what I just said. "Are... Are you serious? I mean... I didn't even do a good job at all."

"What do you mean Chloe?" I say as I turn over to face her my hand trails from her butt all the way along her body up to her face. "You did amazing for your first time. Few girls can take it in the ass that well their first time and they usually have some prior experience. You went in blind, that's badass."

She giggles and blushes "Hihi well I mean... Mmmh thank you. For a while there I didn't think I could do it, that this was a mistake but then I did it. I made you cum using only my butt." Her hands reaches back and rubs it "Although it did hurt pretty bad... I'm probably going to be sore tomorrow, ouch..." Then she looks back at me and gets scared I feel bad "Not that I regret it. I loved it, thank you! It was an amazing birthday present!"

"Yeah that's the down side with anal..." I reply but then goes in for a quick kiss. "... But let that be a reminder for you about what a good job you did. Making me cum with this amazing ass of yours.

She smiles so big but then notices something. The clock "Oh shit we should get dressed and back to the party!"

"Oh yeah damn! Hope no one gets too suspicious." I reply

"No we will just have to play it cool... As cool as we can..." She puts on her jeans by jumping up and down "Damn who knew I would celebrate my birthday with a ass full of cum?"
