Bruce kisses back eagerly, groaning quietly when his shirt is unbuttoned and he feels the rush of cool air followed by the heat of Tony's hands against his bare skin. He gasps again when Tony pulls out the nails once more, another shiver running through his body.

Tony isn't really making it easy for Bruce to focus properly - he talks about clothes but then distracts him in the next second and Bruce completely forgets about trying to remove them as he buries his hands in Tony's hair again and kisses him back again. He moans into Tony's mouth as he continues to be teased, wriggling and arching underneath him in a desperate need to find relief as his pants start to grow far too tight.

If this is just the start, Bruce doesn't even want to think what else Tony is going to do to him - he just wants whatever it is Tony will give, and he just knows that it'll be good. It'll be very good.
