Just the two of us

"No offense, Katrin," I say, "but I'm in the middle of learning some new things about my roomie here. And about myself. I'd like to explore these new feelings alone."

"I understand," says the older woman without a hint of jealousy. "I'm happy to watch."

I return my attention to Amber and redouble my efforts--and by that, I mean I add a second finger. Her pussy grips me so tightly, as if it were a glove. She closes her eyes and returns to her earlier wailing.

"Oh! Ah! Ah! Eugh! Oh! I... Oh! I feel like...I should be...Ah!...returning the favor..." she gasps.

"Later," I say firmly. "Right now, all I want is to hear your sweet little cries."

Amber obliges, and her beautiful voice sings out a staccato solo as I finger fuck her towards a grand conclusion. Sweat from the heat of the sauna pours down her body, mixing with with the arousal coating her inner thighs. She rises in pitch and volume. I can sense the exact moment she climaxes. Her pussy squeezes me over and over as she shudders and lets out a final piercing note. Then she collapses in my arms, exhausted. I shower her face in kisses.

"Now you," she murmurs when she's halfway recovered. "What do you want?"

I think. "I'd love to try tribbing our pussies."

We sit down, straddling one of the slatted wooden benches, facing each other. It take a little contortion, but eventually we are able to press our crotches together. It isn't particularly stimulating, but it is intimate--her folds rubbing against mine, the scratchy feeling of the blonde stubble on her pubis pressing against my thigh. We spend several wonderful, lazy minutes scissoring. The build-up within me is slow, but inevitable. Amber can sense it. Her eyes shines when she pushes away and attacks my pussy with her hand, vigorously pushing in and out while her thumb rubs circles around my clit. It's too much. I'm seeing stars, and my body convulses, overwhelmed.

I go somewhere else for a while, and when I return, Amber is tucked under my arm, her head pressed against my breast. "Oh, Lilah!" she breathes out. "I love you so much."

I think about how to respond. If I said "I love you, too", I feel like I'd be committing to something long-term with Amber. Is that truly what I want? Or is this a one-time thing? And if it's the latter, can I bear to break my roomie's heart by letting her down?
