I situated myself between her legs, slid back inside her pussy, and then gently settled a good bit of my weight on her hips. I held my chest up over hers so we could kiss and see one another. Avery rolled onto her side, pressing up against the both of us, and watched through glazed, sated eyes. Having her here only added to this incredible experience. As long as she didn’t feel guilty afterward, I suspected this would ultimately bring us closer together. Not as lovers, but siblings. You couldn’t share an experience like this and not come out unchanged.
The constant state of arousal over the last half hour or so had me primed to blow. Even still, I managed to refrain from just going at it. This was going to be a memory for a lifetime and I had just enough awareness to pack away every last detail.
“You gonna cum inside her?” Avery said. I still had trouble believing that she’d come to not only tolerate but actively encourage this little tryst. And yet…
I didn’t break stride as I considered the question. “I suppose I’ll cum wherever the current owner of my nuts wants it.”
Kaia wrapped her legs around my butt and pulled in. I thought that was a sign she wanted me to climax inside her. I was wrong.
“On my tits,” she said. “Seems most appropriate, given our arrangement.”
I shook my head and smiled. “Sure.”
From there, it was just a rut-fest. I fucked my cousin thoroughly, only occasionally changing up the pace or angle to keep things interesting and moving toward the inevitable conclusion. Kaia held me tight at one point to ride out an orgasm. Once she finished, I found my final groove and barreled straight toward my own end.
My body wanted me to just power through climax and cum inside Kaia’s pussy. The remnants of rational thought dragged me back from the brink, though, and I pulled out and got up on my knees just in time. Avery scooted back a bit as I started wanking through the climax.
Kaia gave me a sultry look, then squeezed her breasts together, creating one big target. The first jet of cum actually overshot the target, hitting my cousin mostly on the chin and throat. The second plastered her tits and abdomen, as did the third and fourth. By the time I finished squeezing out the last little bit, Kaia was giggling and Avery was giving me a golf clap.
“I’d have to guess you didn’t leave anything behind,” Kaia said. “So I got my fair end of the bargain.”
I chuckled, sinking back on my haunches, exhausted. “Yeah, I think that was it. Definitely a fair trade. Pleasure doing business with you.”
We shook. Kaia then wiped some of my cum off her chin and licked it off her finger.
“Not bad,” she said. She scooped some more and offered it to my sister.
“Pass, thanks,” she said, rolling her eyes.
“Your loss.” Kaia licked up a bit more, but eventually asked for a tissue on grounds that she was still full from Christmas dinner.
There was a fair bit of cleaning up all around as we came down from our crazy high. We had a few laughs and, thankfully, no one seemed inclined to regret what we’d done later. As things wound down, I got up to fetch my shorts.
