Eruraviel
The slap sent Eru over the edge, her pussy clenching up and squirting hot sticky juices onto Sage's hand. "Ahhh! Mistress, please, this is too much!" She exclaimed. Her cock continued growing in size, thickening and lengthening until it was about the size of a bull's member. The fabric wrapped around it though, miraculously, didn't break. It stretched to accomidate her increased size, and soon, Eru's balls caught up. Each of them had swolen to about the size of a coconut, and the elf was struggling to stand up from the increased strain of the weight and her unbelievable arousal.
The head of her cock was constantly leaking precum, and the hole was gaping wide enough to stick a finger into, as if her cock was trying to come, but her balls were prevented somehow from releasing the pressure.
The elf bit her lip, holding back her moans as her pleading eyes stared at Amanda's face.
