"Why don't you just relax and let me do all the work." Starfire suggested, "I'll go nice and slow since this is my first time too."
Beast Girl just nodded with an anxious little smile.
"Now lean back," Starfire suggested, "Since you and Jinx were so kind as to use your mouths on me I feel I should return the favor."
"Ok." Beast Girl said meekly.
Lying down next to her friend, Starfire slowly positioned her head between Beast Girl's green thighs and observed in close detail her first pussy.
'It is rather strange looking, though I will admit that I do feel a bit of attraction to it. It looks a lot smaller and tighter then ones I saw in Cyborg's magazines but basically the same.' Starfire thought to herself as she took her index finger to cautiously explore her friend's snatch, noticing how Beast Girl reacted even to her gentlest touch, 'She is very sensitive down here as well.'
As Starfire's finger slid up along Beast Girl's lips and crossed over her clit, Beast Girl's body jolted and for a second she grasped Starfire's bed sheet tightly in both hands.
"That didn't hurt, did it?" Starfire asked.
"No, it didn't hurt but I definitely felt it." Beast Girl said as she caught her breath, "I've touched it before myself but it's really different when it's someone else touching it."
"Yes, it's the same with my Glornob."
"I'd imagine so."
"Imagine? Has no one but yourself ever touched your glor… penis?" Starfire asked, a hint of surprise in her voice.
"Yeah, well…." Beast Girl admitted bashfully, "It's not always very easy to find someone interested in doing that, especially if you're not hot like Robin or buff like Cyborg."
"Surely you must have had the chance with someone though? I mean, if not with someone you have feelings for then you at least have used one of your species' ritual Glory Holes?"
"Well, until recently I didn't even know such a thing existed and even if I did it wouldn't have mattered. As Beast Girl they'll let me into the club no problem but as Beast Boy I wouldn't have made it passed the bouncer."
"So, females receive special treatment at such places?"
"Well, yeah. Didn't you notice the line when you came into the club? Didn't you think it was weird that you didn't have to wait in line?"
"I did at the time think it was odd but I hadn't realized that was what was happening."
"Yeah, well that's what's going on."
"Well, that is simply unacceptable."
"Yeah, but there's nothing anyone can do about it."
"Perhaps I can not assist the people who wait in line but I can assist you! When you become Beast Boy again I will pleasure you!" Starfire said proudly.
"Oh, ok." Beast Girl replied, sensing that Starfire wasn't going to take no for an answer.
"Now, relax again and I will continue what we started." Starfire commanded. Again, Beast Girl simply nodded as she lay back down.
'Now, to do as I promised.' Starfire thought as she leaned in closer, stuck out her tongue and traced it around the outside of her lips.
Starfire was quickly learning her friend's body, finding Beast Girl's reactions an easy gauge of what felt good and what felt better. As she worked, dodging her tongue around Beast Girl's lips, Starfire could taste a strange fluid building up on her tongue. It was different then the taste she was used to though not entirely unpleasant; in fact, it was a far less harsh taste then Robin's, Raven's or her own. The more Starfire worked, the wetter Beast Girl became and the more she moaned and squirmed. As she gently worked Beast Girl's clit, licking it like it was an ice cream cone, her moans became deeper and longer until they suddenly lurched into a much higher pitch accompanied by a sudden burst of wetness.
"Oh wow," Beast Girl whispered as her body finally began to relax again, "I think I just came."
"Was it as good as it looked?" Starfire asked as she lapped up an extra taste before pulling her face back.
"It was nothing like I felt before. It was different then as a guy. I don't even know if I can explain it." Beast Girl said, overcome by the experience, "It was like a thousand feathers tickling me at once, but it wasn't like a tickle feeling at all."
"You are correct, that doesn't make much sense. I wonder how the feeling will compare to the feeling you'll experience when I give you a male orgasm later." Starfire wondered out loud, "I would be very interested in knowing as I do not know of anyone else who can truly give such a comparison."
"About that Starfire…" Beast Girl began and then stopped to contemplate what to say next.
"Yes, I know it may seem strange to be planning a future encounter when we haven't yet finished this one but…"
"That's just it; I don't think they'll be a future encounter."
"Why not? Did I offended you some how because if I did I truly apologize. I am not completely familiar with all the human customs surrounding sex but I was hoping…"
"No Starfire, it's not that. I'm not offended just kind of overwhelmed. I wasn't going to say anything until I was sure but when you mentioned it twice now it kind of slipped out."
"What is wrong?"
"Well, I'm totally open for having future encounters with you Star but I'm not sure if you sucking my cock is going to happen."
"Why not? I believe we would both enjoy it." Starfire said, trying to convince her friend.
"I don't think I'm going to have one." Beast Girl said awkwardly.
"Why not?"
"Well, remember how I explained that to transform into a girl and to stay one I needed to swallow male cum?"
"Yes, you said that earlier today; I do not fully understand how that works but I do clearly recall you saying it."
"Well, every time I've done it I can just sort of feel what's going on inside of me. I start out with a sense of fullness and the feeling slips away second by second until it's gone. It's like I have an egg timer inside my brain letting me know how much girl time I have left. At first when we were giving you head everything felt normal but once I actually swallowed your load things felt really different. I didn't feel a sense of fullness wash over me, it felt more like a giant case of static shock. And then there wasn't anything; no fullness, no hunger, nothing."
"Perhaps my seed is simply extra strong." Starfire suggested.
"At first I thought maybe I was just really full since it did taste really strong but as I flew here nothing changed. I haven't felt any decay at all and even if your cum is double strength I should be feeling like time is running out by now. If anything though, I feel more girlish then when we started."
"I do not always fully understand the things you humans say, what with all the expressions and double meanings that take time to learn so perhaps I am mistaken but are you trying to say that you believe…."
"I think something about your alien juices may have made me Beast Girl permanently."
"I am sorry, I did not know that would happen. If I had known I surely would not have…"
"It's okay Star, I'm not mad at you." Beast Girl said calmly while she leaned in and gave her friend a comforting hug, once again feeling Starfire's powerful erection being pressed up against her stomach.
"You are not mad that you can no longer be Beast Boy?"
"It sounds weird but ever since the first time I changed it has been harder and harder not to want to change again and stay that way longer. I mean I'm still me, just a happier me. It sounds weird but if anything I feel like maybe I should thank you for this."
"You are most welcome my new girlfriend!" Starfire shouted with joy as she hugged Beast Girl with great enthusiasm, "Now we will most definitely have to go shopping tomorrow! We will have to shop until we fall!"
"I think the phrase is shop til you drop but we'll worry about that tomorrow." Beast Girl replied, "We're not done here yet and it sure feels like you're primed and ready!"
