Susannah comes.
It's even more intense this time, a constant throb of sensation that pulses out from her clit and overwhelms her every single thought with pleasure. A part of her mind floats above it all like a tiny boat riding a massive swell, but all it can do is marvel at the sheer power of the orgasmic bliss that keeps hitting her over and over. Her muscles tense up, locked tight in an attempt to hold onto the moment forever and all the ecstasy that comes along with it. She lets out a high, quivering yowl at the moment when she crests the final, shattering climax and her pussy clenches hard around Robyn's pumping fingers, and then her body can't sustain it anymore and she goes limp.
"That's it," Robyn coos, slowly withdrawing her fingers and leaving behind a trickle of wetness that seeps into the mattress, already damp in places from so many previous orgasms. Susannah mews softly as they slip free, the tiny sensations magnified by post-coital sensitivity. "That's my good girl. You're such a good girl, aren't you?"
Susannah doesn't respond, at least not verbally. But she curls her body up against Robyn's, seeking out the warmth and comfort of the other woman's skin almost instinctively. She whimpers a little, her hindbrain recognizing the praise in Robyn's words even though her conscious mind is still recovering from the shattering bomb of a lovemaking session that left her thoughts resembling an impact crater. Ideas flash through her head sometimes, but even those tiny bits of her mind that are intact are distant, unable to connect into anything resembling a real train of thought.
It seems to be what Robyn is looking for, because she rests her hand possessively on Susannah's hip and says, "Of course you are. You're my beautiful, sweet girl and I've got you. Feel me holding you, safe in my arms, warm and drowsy and peaceful. It's okay to relax into that feeling, pretty girl. Just melt into my arms, into my voice, and let everything else go for a bit. Simply let yourself be in the moment for me, good girl."
Susannah murmurs something, but even she doesn't know what she's saying. She can still feel the pleasure saturating her mind, the remnants of a chemical high still floating around in her brain and fuzzing out her thoughts with serotonin and dopamine and oxytocin and all sorts of other natural drugs that she knows the exact function of when they're not working their magic and melting her into a soft puddle of submissive mush. All she really knows right now is that she's happy and she feels good and she wants to be cuddled.
