Golden Trades and Rejection by RonnyDonny (orphan_account)

Summary
“I have another offer,” Dream smiled coyly, stopping uncomfortably close to Techno, raising a finger to gently raise his chin with just his index finger. “I’ll give you so much gold you could practically drown in it. In exchange, let me fuck you properly this time, and by that, I mean that I want full control this time.”
Techno lightly slapped away Dream’s hand, sighing heavily. He was getting tired of this constant talk of trades and such, and while he may have a small innate attraction towards gold, it wasn’t nearly as strong as Dream seemed to think. It had no true value to him, and he already had quite a fair amount in itself. The only reason it worked last time was because they were golden apples, something that actually had use to him.
Or
Techno and Dream have slowly fallen into a friends with benefits type of situation, but Techno is growing tired of Dream constantly winning his affections over with useless trades and deals. For once, he just wants to be treated with respect and dignity, not like some dog that can be won over by treats.
[Sequel to "How About A Trade?"] [Can be read as a stand-alone fic, but it is encouraged to read the first fic before reading this one]

Fluffy PWP with the Fellswap bros. I like knitting and I really like thinking about Black's hands if he's as tiny as I like to think. This may be little more than how I like to think an average evening in their lives would be.
Devolves into less fluffy PWP as it progresses because I can't control myself
