The sight of her skirt tented up by an enormous erection wasn't all that upsetting for Katie. She could have done without Tiff seeing it, but she was more concerned about taking care of it so they could get on with looking through the house. Giving the matter some thought, she realized that her biggest worry was that she didn't want Tiff watching her masturbate. Maybe if she had more experience with having a penis it wouldn't have been so bad, but since this was going to be her first time she didn't know what to expect.
"Don't worry Katie, if it's got you so upset I can help."
Katie put her hands protectively in front of her penis, horrified at what her friend implied with such a statement, "Why would I want another girl touching my penis? Or are you a lesbian or something?"
Taking a step back Tiff held up her hands, "Sorry, I was just thinking that because I have a boyfriend I might know more about penises than you."
A statement like that struck Katie as being a low blow, but she did remember how good it felt when Tiff touched her penis earlier, "Fine, but just this once. Having a penis doesn't make me a lesbian after all."
As she lifted up her skirt, revealing her thickly veined and throbbing erection curiosity got the better of her, "What are you going to do Tiff?"
"Nothing kinky, just a hand job. We just need to get this taken care of," done talking for the time being Tiff began to tend to her friend's need, gently stroking at first, but then as Katie began to thrust into her hands she increased the pace and applied gentle pressure.
How good it all felt amazed Katie, never would she have expected having a penis to feel so wonderful. It was nothing like the gentle warmth and slight pressure in her pussy that happened when she was aroused before she grew her penis, it was an intense and highly focused pleasure. The fact that she was now starting to get sensations of pleasure from her pussy made it even better, having a penis served to double how good it felt to be aroused.
The sensations were so incredible that before she knew what was happening she orgasmed and a jet of clear fluid shot from her penis, similar to that which was flowing from her pussy. Clearly not expecting her to ejaculate, Tiff stumbled back in surprise and bumped into the medicine cabinet, causing one of the jars to shatter and spill its contents all over her.
"Oh my god Tiff I'm sorry!" The thought of some of the things in the cabinet hitting her friend terrified Katie.
