I sat there stunned. Carol had just fucked Tom while I watched.  Tom's cum was seeping out of her cunt.  Her tits were covered with love bites.  She glowed with the aftershocks of orgasmic sex.  She smiled with sexual satisfaction.  She looked up at me with a question in her eyes.  I pulled her to me and held her sticky body.

Tom got up, his cock still semi-hard and coated with his and Carol's intermingled cum.  His cock left a wet trail on Carol's body. He leaned down and gave Carol a hot kiss and then left. I was thrilled.

I thought, sex, sex, sex.  That's what got me to allow Carol to fuck Tom.  I still had qualms about what we had done, but couldn't deny the overwhelming thrills.  I asked Carol what she thought of our adventure.  She told me that she loved the sex, loved Tom's cock, loved me watching, loved the thrill of wild new sex.  But she needed to know if I was OK.

Rather than answer her, I started finger fucking her dripping cunt.  I kissed her open lips and shoved my tongue deep into her throat.  I pinched her already hard nipples and moaned into her mouth.

I had to reclaim her.  I pushed her down on the sleeping bag and without any foreplay rammed my cock into her cunt.  I could feel Tom's cum washing over my cock.  Her cunt was warm, wet, and juicy.  Her cunt lips were covered in froth with Tom's cum, open and freshly fucked.  There was a wildness in my fucking.  I was in a frenzy.  I pummeled her cunt with my cock.  Our fucking was like a madness had taken over.

Carol moaned, "Yeahhhh, FFFuck me, Dirty Girl."

My body spasmed, cum was shooting out of me like a machine gun, cum mingled with cum, cock exploding.  I couldn't stop.  I kept cumming, never going soft, cock, fuck, cock.  Carol pulled me down to a hot open-mouthed kiss.  I slapped her tits and she groaned.  I slapped them again, harder.  

Carol, "Oh Yeahhhh, dirty girl girl girl."

She reached up and slapped my face and then did it again.

We were like two punch drunk boxers, slapping each other while I kept cumming and cumming in Carol's cunt.

I groaned, "CCunt. Whore. Cunt, slut. Ahhhhh cumming."

Carol froze her face in exquisite ecstasy, mumbling crazy words.

I finally came out of my trance and pulled Carol to me.  I held her as she was still in the grip of her violent orgasm.

I fell onto her and we wrapped our arms around each other.  We held on for life.  

The craziness slowly ebbed.  Carol and I were lying side by side, breathless and spent.  I knew we had to talk about her fucking Tom but I didn't know what to say.  This was the wildest sex thing we had ever done.  I knew I should hate it but my cock said differently.

Carol spoke first, "I know why we did it. The thrill of it."

I looked into her eyes.  I knew she was right.  We had reached a new high in sexual thrills.  We had risked a lot and we had gained a lot.

We both knew we would do it again and again.  We knew the thrill was too wild to not do it again. It was addictive. We left the cottage that night.  I assumed everyone knew what we had done with Tom.  They all knew Carol and I played wild sex games.  Most of the men had had hot dances and furtive kisses and quick gropes with Carol.

When we got back to Boston we began scheming about what we would do next.  The talk and plotting about Carol fucking someone else got us hot and horny. 

We fucked several times that night.  Each time hotter than the last.  Neither of us could get enough.  When morning light came through the window, Carol was on her hands and knees and I was pounding her cunt.   

We ate a dazed breakfast and couldn't stop smiling at each other.

I said, "We need some rules. No sneaking around, no regular partners (except maybe Tom). If either of us says stop, we stop. We both need to approve of the sex partner. No anal. Sometimes a threesome. It has to be thrilling!"

We met up with several of our friends Sunday night for drinks.  Some of the guys flirted overtly with Carol.  One or two of them asked if it were true that Tom had fucked Carol.  I simply smiled.  We were all exhausted from the weekend and decided to turn in early.  Carol gave hot tongue twirling kisses to a few of the guys.

We live in Boston.  Boston has so many possibilities for sex games:  conventions, hotel bars, college fraternities, dance clubs, etc.  We knew we'd be exploring all of them.
