She whimpers.

(--he's playing with her breasts, which she has, because she is a girl--)

"Was that a good noise, or a bad noise?" Bruce murmurs, running his hands down Aarons' stomach.

"Good," she says, "very good--"

He remembers what kind of underwear he's wearing, realizes Bruce is maybe really close to trying to take his pants off, and pulls off his pants and underwear in a single hopefully-not-that-conspicuous movement.

The pants-and-underwear removal is very conspicuous! Bruce is now highly aware that this person he has basically promised a blowjob is now not wearing pants or underwear! And that's awesome, because he's pretty excited about giving that blowjob. He hastily shifts his attention dickwards, shuffles along the bed a bit, takes a moment to consider his approach, and starts by licking a line from the base of said dick to the head. 

Oh shit Bruce is touching the gross thing.

He tries really hard to remap the sensations-- to think that Bruce is licking his clit because he's a girl-- but he can feel himself starting to get soft.

Oh no Bruce is doing a shitty job. Fuck. Now what. He can't ask what Lev wants, that would be drawing attention to the problem and embarrass him. He hesitates, runs a nervous hand over the inside of Lev's thigh, tries sucking the head of his cock.

This is fine, this is fine, he can get soft and then eventually Bruce will give up and he can suck him off or get fucked and it'll be nice--

"I'm sorry," mutters Bruce. "I still don't know what I'm doing. I, can try to figure it out?"

"It's fine," Lev says, "I don't really like... being touched there... at all."

"Oh. Okay." That's sad but maybe it will still work for the Nectar if Lev masturbates while Bruce is licking his nipples that is so not the priority right now. "We can, go back to what we were doing before? I liked that." He still selfishly wants to make Lev come, both for science and because he wants to see it, but if that isn't happening it isn't happening.

"I can just suck you off, I'm really good at it."

"Um. Don't get me wrong, that sounds awesome, but also I want to make this good for you too? If you aren't having fun we should. Not." Bruce is definitely not an ethics expert but he knows that if someone doesn't want to have sex then you shouldn't have sex with them.

"You can play with my nipples if you want to."

"I like making you make cute noises." Blush.

Cute noises with his male voice-- oh come on-- "We can do that."

"Oh good." Bruce repositions so he's lying on his side next to Lev, partially propped up on one arm. His own cock has started going soft during the interruption.

Lev reaches out and starts petting his hair.

This can be reciprocated unproblematically! He hopes. Hairpets!

Reciprocation is rewarded with smiles!

Yay! They can keep this up for a bit, and then Bruce can go back to nipple-licking. He's steadily getting hard again.

If he keeps that up he will rapidly have a very happy and very whimpery Lev.

All Levs are good, but happy whimpery Lev is so much better than awkward sad Lev. Also Bruce is super horny now. Maybe he can grind against Lev's thigh without touching his dick? He moves partway there and then decides not to risk it, stops with barely an inch of air between them. He can feel Lev's radiating body heat and it's almost like being able to see in infrared.

Lev notices this, reaches down with one hand, undoes his pants, and starts to give him a very competent handjob.

"Hnnnngg mmmm yes good"

Mm. Bruce can still say things. Probably instead of that there should be kissing.
