The awkward level between them had risen dramatically with the dating decision, it wasn't like either of them had never had a girlfriend/boyfriend (respectively), hell neither of them were virgins, they had even talked about it, but the fact that they had just decided to date each other had multiplied the level of awkwardness brought on by the unfamiliar parts and changes to their sexuality and had both of them acting like the most nervous fumbling virgins in the world.
"i, Uh, Yes?" Jon sputtered. His brain was having trouble putting together the fact that he was going to get a chance to feel up a very nice set of large boobs and that they were on Karyn to boot, at the same time that he had a set of his own. "I... you can feel mine... too I guess, er, since you seem to like them a least a little." he managed to smile as he finished talking.
Karyn grinned, Jon's permission, and little joke, giving her back a bit of her self-assuredness and helping her get over some of the awkward. She stood, feeling her now free, erect, penis bouncing a bit as she moved. "Well come here and give me a kiss then!"
Jon stood, feeling his boobs swing as he leaned forward, pulling at him at bit more as he straightened and bouncing slightly as he finished standing.
The walked towards each other, each feeling the unfamiliar movement of new parts, Jon's boobs slight bouncy jiggle with each step and the movement of his legs emphasizing that there was an empty space between them, Karyn feeling her new testicles being pushed slightly by her thighs with each step and the slight bounce of her erect penis with each step, all felt strange to them, Karyn additionally finding herself looking at Jon's boobs again the same jiggle fascinating her.
When they reached each other Karyn put her arms around Jon's shoulders and pulled and leaned in and kissed him on the mouth. Jon responded and the kiss continued with tongue, he put his hands around her waist and let himself be pulled closer, their boobs touched and then started to squish as they came together, Karyn let her arms slide down the side of Jon's body until she was grabbing his but and she gave him a little pull closer and she felt her penis poke the front of his torso. Jon felt it and tensed slightly, the feeling was strange to him, but a part of him that came from Karyn with his new vagina very much liked it.
And she broke the kiss "Oh! I'm sorry, I wasn't thinking..." Karyn said.
"It's OK" he said and he moved his hands down to her butt and pulled her closer, further squishing both their boobs and pressing her dick against him more. "I... I actually kinda liked it." He felt a flush of arousal and wetness between his legs as the tip of her dick slid upwards and it's length flattened against his lower body.
"Oh... yeah, I guess you would... God it feels kinda hot to have your boobs squished against mine like this."
"Yeah... weird as hell for me though..."
"Want to stop?"
"Not a chance." Jon said and he kissed her again, feeling her squeeze his butt.
The physical intimacy had broken both of them out of the feeling of awkwardness and they were starting to feel comfortable talking again. Sure the changes felt weird, but they had talked about all kinds of stuff before, including getting sex advice when they were dating other people, they should be able to talk about this, and exist together naked.
"mmmh," Karyn said after a few minutes as they broke the kiss again, "Let's move to the bed, I want to take you up on playing with your boobs."
"Only if you take your bra off so I get to play with yours"
"Is that all it takes? Deal." She let go of him and stepped back, pulling her shirt off. "You get to undo it, I'll turn around to make it easy for you, I remember how much trouble you said you had with your last girlfriend!" she said turning, with a smirk, to give Jon easy access to the clasp.
"Hey! I eventually got the hang of it... sort of", Jon said as he undid it, "well it's a lot easier when you can see it."
Karyn giggled at him and jumped onto his bed. "You're going to get a lot better at it now that you'll be wearing your own bras."
"Uhg"
"Really you'll want them, believe me, I needed it even before my stupid wish. Anyway less talking about your boobs more getting them felt up."
Jon was finally feeling relaxed, it still felt very weird to have these parts and seeing his former dick bouncing around after Karyn landed on the bed and liking it rather a lot felt even weirder, but their conversation had settled into a more sexual version of their usual banter, and that felt really nice.
Jon got on the bed next to the now totally nude, except for her socks, Karyn. She grabbed his head and pulled him down into a kiss, her other hand reaching up and starting to play with one of his dangling boobs, gently. It felt good, very good, and he found himself moaning into her mouth softly.
Karyn giggled and broke the kiss, "Wow, I see why guys like doing that now... well not 'why', why, but it's a lot of fun... and it sounded like you enjoyed it too."
"Oh yeah, I... god are yours so sensitive?"
"I don't know, I can't feel how sensitive yours are." she grinned at him.
"You know what I mean!"
"Yeah, yeah, it feels pretty good for me too."
"Oh?" Jon said as he reached out and gave one of her boobs a squeeze.
"Ow! Gently! I know I told you like a year ago when you were dating Ashley."
"Sorry, sorry"
Karyn pushed him over onto his back and got into a more comfortable position sitting on his abdomen, where she had both hands available and started playing with his boobs. He could feel her balls resting on him and as much as he liked seeing her boobs he was just as distracted by her hard dick.
"Like this, see, use your thumbs around the nipples, and you get the rest of your hands to feel and enjoy for yourself." She said, demonstrating on his boobs as she spoke.
"Yeah, oooooooh", he moaned, "That feeeels gooOood." he reached up and started playing with her boobs.
"Oooh, yeah that's better Jon, mmmm, God you have really nice boobs."
"mmm thanks... yours are pretty nice tooOOOoo."
"God if we keep doing this we're gonna end up having sex aren't we?"
