“Hey guys,
 
 
heh, see what I did there? :P Yeah, a little “pun” to start with.  
Anyways- funny story: Someone on DevaintArt wants to stay anonymus but asked for a commission since months. They wanted me to draw something “NSFW” (although it’s listed forbidden on my Commission Sheet). We discussed about it and we had a deal of them paying me once like a $15 pledge and he got that kind of sketch-pic.
 
I was wondering about the idea they asked me for at first, but I won’t complain XD They wanted me to draw Snoopy having a nice “seductive” dream featuring me and they decided for the butt to be shown instead of other scenarios. Snoopy enjoys this dream while sleeping that he feels a liiiittle bit aroused, but only a bit XD
 
Although this piece was first said to be NSFW, it’s not that bad and they did not want me to draw actual genitals, so I would just call it seductive.
 
Nevertheless, I just hope you like it, I enjoyed working on it and I thank the commissioner for it^^
