Matt and I went to our friends’ last house party with only one objective in mind: to swap partners with Elaine and Ralph.

The two of them are in an open relationship, and Matt and I swing, so we knew it was possible. We’d wanted to swap with them for months, but we’d never really had the chance. Their party seemed like the perfect opportunity.

We had a great time drinking and talking with everyone, and the rowdy game of charades that broke out was surprisingly entertaining, but we couldn’t wait for things to wind down. As people started to leave, Matt and I made a point of offering to help clean up. It would get us alone with our hosts and open the door for some sexy swapping.

After the last guest left, Matt and Elaine started picking up glasses while Ralph and I rinsed out beer bottles and gathered dishes. I started flirting with Ralph as soon as we were alone in the kitchen, touching his arm and bumping into him whenever I tried to move around the room. He flirted right back, copping a feel whenever he could and saying everything in a suggestive manner. Even “You wash, I’ll dry” managed to sound dirty when Ralph said it.

When Ralph accidentally splashed some water on me, it soaked through my thin white T-shirt. I playfully started to fight him, pretending he’d done it on purpose. In the middle of our struggle, Ralph grabbed my head in his hands and pulled me in for a hot kiss. I dropped the sponge I was holding and kissed him back, forgetting all about the dishes.

As we kissed, my wet hands traveled under his tight T-shirt while he worked his fingers into the waist of my jeans. We touched each other everywhere we could reach, and when we ran out of readily available flesh, we started pulling off each other’s clothes.

As we stripped, shirts flew one way and jeans the other, but it wasn’t until we were down to our underwear that we realized we didn’t want to get it on in the messy kitchen. Ralph grabbed my hand then and pulled me into the living room, but he stopped almost as soon as he walked through the doorway. On the futon across the room were Matt and Elaine, already mid-fuck. Our partners had obviously gotten a head start.

Ralph and I watched them for a minute, then he dragged me toward the couch. He sat down, pulled me into his lap, and resumed kissing and fondling me.

Ralph made a move to unclasp my bra, and as soon as it was off, he leaned in to suck my tits. He laved my nipples with his tongue, then traced circles around each one. He was driving me crazy, and I started moaning, my noises blending with the moans and groans coming from across the room. He kept at my nipples for a while, until I pushed him away to take a turn at sucking and kissing his earlobes. I felt his cock twitch against me through our underwear as I nipped and sucked on his neck and ears.

We finally stood up from the couch and pulled off our underwear. As I stepped out of my panties, I glanced over and saw Elaine on top of my boyfriend, riding him reverse-cowgirl. They were maybe ten feet away from us, so close that I could almost reach out and touch them, and watching them going at it really got my juices flowing.

Once Ralph had his underwear off, he pulled me back on the couch. He put one knee on the cushion and left his other foot on the floor, then pulled me into his lap, angling my hips upward. As he slid his cock into me, the position made him go deeper than his seven-inch cock should have allowed, and he filled me perfectly.

Ralph had me gasping from the first thrust, and I only got louder as he picked up his pace. As he continued fucking me, he used one hand to hold me in place while he moved his other hand to my pussy and rubbed my clit. While he was focused on me, I turned my head to look at my boyfriend. Elaine had turned around by then and Matt was sucking her tits while they fucked.

Watching the other two humping each other was arousing, and the more I watched them, the harder I tried to meet Ralph stroke for stroke.

Ralph kept increasing the pace as he fucked me, and soon he was banging me hard, his balls slapping against my ass. His finger was moving faster on my clit, and my climax built as we fucked. I felt my body tingling with pleasure, and then it seemed as if waves of excitement were washing over me. Ralph made me come faster than anyone ever had, but he didn’t stop fucking me. He didn’t even slow down.

He pounded away, bringing me to a second, equally explosive climax before he finally came himself, pulling out in time to shoot his load across my stomach. I love watching my partners come, and I loved that Ralph knew to do it without being told.

After he came, we collapsed on the couch before turning to see what the other two were doing. I’d been so caught up in my own pleasure that I hadn’t been paying attention to them, and I saw that they’d finished, too, and were curled up on the futon, half asleep.

Ralph and I rested for a few minutes, catching our breath, then took a shower together, fucking one more time. By the time we’d finished, Matt and Elaine were awake. Matt and I left then, but as soon as we got home, we celebrated our successful swap with a wild fuck before crawling into bed for some much-needed sleep.
