Theodore getting his thick rump stuffed and creamed by Alvin and Simon in the middle of the night. This semi sequel/continuation to Nuts and Cream was written by my lovely husband on furaffinity at /user/leemurofluff He also made a lovely picture to go with it which you can see on inkbunny at /s/2720906

Theodore finds Alvin and Simon sharing a routine intimate moment and gets invited to join.
