Both at once.
Her lips closing around one, then the other, the warm, wet suction of her mouth enveloping him while her tongue pressed and rolled in careful, attentive circles.
His groan came from somewhere low in his chest.
The sound of it moving through his whole frame.
'He makes that sound.' 'That exact sound.' 'I know that sound from somewhere I cannot access and I am making it happen right now and I cannot stop and I do not want to stop.'
"Fuuuck—" He exhaled. His hips kept driving into Sugar, the rhythm maintaining itself. "Yes. Just like that, Nano. Suck them while I ruin this tight cunt."
PAH! PAH! PAH!
"AAANGHH~!! HIIEEK~!! OUNGH~!!"
The vibrations from her mouth traveled up his shaft.
She felt him twitch.
Felt the specific, immediate response of a body receiving something that was working.
She sucked harder.
His hand reached around Sugar.
Found her breast from the front.
Grabbed.
