Um, no. I wouldn't feed this snake any sooner than once a week. And if for any reason, you fed 2 items (STILL not recommended, see above) or feed on the large side, about 10 days apart is what I'd do.
According to the feeding chart on this site, at 300+ grams, a proper meal would be ONE rodent of 20-32 grams, roughly once a week.
If you don't allow enough digestion time, your snake may regurgitate, & that can HARM him.
Something to keep in mind- snakes often act hungry for hours or even a day or more AFTER they've eaten a perfectly-sized meal. (The same thing we humans do when we eat too fast- & we don't realize yet that we're full.)
Also, we cannot tell from that photo if your snake is over-fed or under-fed- but he sure doesn't look thin to me. Overfeeding a snake is bad for their health & longevity.
