When they were done, Eva readily matched the position Charlene had been in — giving me the best view I'd ever gotten (at least, since she started puberty) of the area between her thighs. Eva had opted to sit on the "near" side of Charlene, so I didn't have any trouble making out the cleft of her sex amid the dark blond curls of her pubic area. At the top, the hood over her clitoris was barely visible; her labia were thin and the area between them appeared to already be glistening faintly. It took only a few moments for Charlene to get herself seated on the floor between Sis' feet. Again, their positions ensured that I had a good view of what was happening as Charlene initially contented herself with simply leaning forward and just looking at Sis. After just a couple of minutes, I heard Eva tell Charlene "Go ahead and touch me, if you want to — it's only fair."
With that, Charlene slowly moved her hand between Sis' legs… and after a brief hesitation, made contact with Eva's mons. The sight as Charlene's slender fingers tenderly probed and manipulated Eva's womanhood soon had me sporting what I was sure was the biggest and hardest erection I'd ever had; it was only a couple of seconds effort to free it from my pants and underwear and begin stroking myself as I kept my eyes locked on the sight before me. Charlene whispered something I couldn't hear to Sis and got a nod in reply; it was when I saw the ends of her fingers gently ease toward Evas opening that I couldn't hold back any longer, and sprayed the wall of my closet with what felt like quarts of my cum.
Even as that was happening, however, I had my eye glued to my viewport into Evas room, and was able to see that even though Charlene barely had the first digit of a single finger through the portal to Evas sex, it was enough to have Sis' breasts visibly hard and tight, and her nipples erect — as well as thoroughly anointing the invading digit with her female essence.
It wasn't just Eva that was feeling the effects of Charlene's manipulations: it was plain as could be (even from where I sat) that Charlenes breasts were tight and sporting hard and erect nipples, too. With her sitting at an angle to me, I couldn't see what was going on with her extra appendage, but the fact that Sis made several lengthy looks that direction suggested pretty strongly to me that something was happening with it.
Still, as Charlene had said, it didn't take her anywhere near as long to learn what she wanted to know about normal female genitalia as it had for Eva to learn about hers; it couldn't have taken as long as fifteen minutes before Charlene slowly withdrew her hand from between Evas thighs and sat back again. When she did, the two of them simply sat there looking into each others eyes and faces…
Charlene sitting on her feet on the floor while Sis remained on her bed, legs spread wide and revealing the glistening opening between her thighs. It was when Charlene finally stood up a minute later that I saw that the small penis protruding from the dark wedge of her pubic hair had changed. Though it hadn't gotten noticeably longer or thicker, there was no denying that it had gotten stiffer and was protruding nearly horizontally from her pelvis instead of pointing at the floor as it had been before.
Eva slowly brought her legs together and her feet to the floor, then stood up to face Charlene. I could see her look down to the protrusion of Charlenes cock for a few seconds before looking into Charlenes face. Several seconds of quiet were broken when Charlene spoke, her tone of embarrassment obvious as she softly said "I… I'm sorry about that, but it's not something I've ever been able to do anything about. I've asked the specialist that I see about it, and he says it's just a part of who I am, and that nothing he can do will change it: if I get, you know, excited, then the boy part of me will react along with the girl part. I… I've kind of figured out by myself that because my body is different enough to have a penis, there's some little part of me deep down inside that just can't help trying to respond to some things. I mean, I don't do it on purpose, or anything…"#p#分页标题#e#
A couple of seconds went by, and Eva told her "It's okay, I guess. I mean, I could tell that you weren't doing it 'cause you wanted to. I knew things were going to be different with you being a hermaphrodite and everything, and I guess that's just part of it. Besides, it's not like you tried to do something, or anything. I don't figure that'll be the only time it happens, so I'll just learn to get used to it, is all."
Immensely relieved, Charlene told her "I… I'm glad you understand, and you're willing to be so cool about all this. I've never had a real friend that I could do stuff with like you before, and I've missed out on SO much stuff because of it."
