Her dirty ass of course!

I make my decision quickly. Thankfully, her pussy juices act as a lube, but being so close to cumming, I can't afford to be gentle.

I shove into Holly's precious little asshole hard and fast, pushing her face further into Jane's pussy. Holly can barely breathe, and is screaming out in agony, but, like a true champion, keeps going.

Holly lets out a muffled scream every time I thrust in and out of her, and I meet strong resistance. It feels as though something is blocking my way, and I have to push extra hard to get my dick all the way in. Straight away, it wins the contest for the tightest hole I've been in, and there's already a tiny streak of blood on my dick as Holly's asshole is practically torn open by my big cock. Holly willingly accepts it all the same, and deals with the pain, knowing that the pleasure of her eventual orgasm will more than make up for it.

"Yes, Holly you filthy little slut! My dirty precious whore! Your nasty ass belongs to me now Holly!" She moans in agreement, as Jane makes attempts to join in.

"Yes, Holly, lick my pussy whilst John fucks you in your beautiful little anus! Cum all up Holly's rectum John!"

This sends both me and Holly completely over the edge.

She cums, in the most intense orgasm of her life, her pussy squirting all over me. I also see trickle of some liquid run down her thigh- it seems I fucked her so hard she may have even pissed herself a bit. Holly had also been doing an excellent job working on Jane's pussy, and as such, their orgasms were completely in sync. Meanwhile, I jizz inside her tight sphincter, filling up her backside with my sperm.

"I love you Holly" I said quietly, as I withdrew my dick from her butthole with a loud pop.

Seeing the state that Holly's poor, dirty little asshole is in, Jane immediately jumps up to soothe it with her sweet little tongue, slowly rimming Holly.

I look down at my dick and see it covered in messy fluids. As if to thank me for a good ass fuck, Holly turns to me without a word and begins to slowly suck my dick clean, which I am greatly appreciative of.

After a minute though, Holly rushes to the toilet. Whilst we wait for Holly to come back, Jane sits naked on my lap and kisses me passionately once again, exchanging my cum between our mouths and the taste of Holly's asshole, as I realize, I've never been so in love.
