She turns on the pheromones

Seeing your hot friend slowly stripping off her robe would already be enough to send you into a bit of a spiral, but that combined with the sight of her... wearing your cock was enough to send you into shock. Sophia slowly let the robe fall off her shoulders, one hand softly stroking her new cock, the other tapping away at your phone. She steps towards you, and you instinctively recoil until an unfamiliar feeling hits your senses. You smell her cock, but it smells almost... warm? Inviting? If you still had a dick it would be stiffening right now, but instead you just feel longing. Realizing she must have turned on some sort of pheromones, you panic but can't bring yourself to turn around, to run away. All you can do is stare directly at her rock-hard cock. Your mouth starts to water.

"That's right." She coos. "This is just a little taste of what you were doing to me last night. I know exactly what you're feeling right now. The attraction, the pull. I bet it's irresistible..." You can't bring yourself to move away, and she steps closer and closer until she's within arms' reach. Your knees wobble. A drop of drool trickles over your bottom lip. You... need it. You need to taste her cock.

Sophia gently reaches up and puts a hand on your shoulder, pushing down. With your legs and willpower already weakened, you slowly sink to your knees. If you thought the smell was enticing before, that was nothing compared to staring directly at her cock inches from your face. Your tongue extends from your mouth. It was hopeless to resist, and Sophia knew it.

"Go for it," she offers. "Trust me, I know how much you want it. Have a little sample. What's the worst that could happen?" She sounds as though she was smiling, but your eyes rest only on her cock, erect and right in your face.
