“And I can trust you?”

Karli growls as she moves upon you aggressively. Already aroused and full of submissive lust you moved your hips and closed her eyes, savouring her touch, seeking to enhance it with your movements. It felt utterly different. Incredibly erotic. Feminine, soft and yielding. Karli was in control and you were all hers now.

Karli took your lead confidently from its hitching as she tugged you both down and moved herself so that your two pussy’s rested together, legs entwined and smirked at you as though reading the your mind. You licked your lips nervously, uncertain as to what to expect but undeniably aroused. This position was new to you. With a cock it made sense. Without ...? You felt self-conscious, asking yourself whether what you were doing was sexy or ... wrong. But Karli knew what she was doing. Karli was in control.

You sighed. You were now both physically very similar. Karli was close to your fantasy woman made flesh and now you were almost her twin. Except uncertain and pliant - easily manipulated. You looked from you own firm rounded breasts to hers and swallowed. So alike. Then you looked from her shaven sex to her own. Delicate lips. Puffy flesh about it. You truly had a pussy now.

“Hold on pet... this is a trick I learned on my first day...” Then Karli started to rub her sex against hours. Your eyes widened at the pleasurable pressure as your hairless smooth crotches slid across each other. Your clit and mound felt every delectable part of her sex. Skin pressed skin. Again you moaned as you rocked your hips with growing agitation. Your vulvae ground together. You pushed back into her and your pleasure heightened. Your pussy was on fire. Your little clit was too damned sensitive!

“This Princess is called Tribbing or scissoring. Feels good doesn’t it Princess?” Karli prompted as your interlocked legs allowed them to stimulate each other. Karli was enjoying the height difference that made her taller. “Every good female lover knows this trick...”

You nodded and whimpered with need. You would never have guessed that tribbing would feel so natural, so right. You found this all unbelievably erotic. Incredibly intense. You barely recognized yourself now. Frottaging with a serum girl as a lesbian. A submissive one at that. New instincts made things feel easy despite their strangeness. She grabbed Your hands and guided them to her nipples.

"You're mine now Princess," She told You. "My little pussy. I'm your Mistress. I own you."

The words sent an unaccountable shudder of arousal through you. As aman you’d always been the one in control. Yet somehow, the thought of being dominated was an incredible turn on. And that arousal increased at the knowledge that it was a woman who was the one who had emasculated you and was controlling you.
