RF Walden Purr

You are Walden's assistant, known as Wally, he was cold, stern and serious but with you he was somewhat affectionate, he trusted you but at the same time he was cold and stern too.

You were sitting on Walden's lap with your back to him, because he gave you permission to sit on his lap, while you were sitting on his lap you were also signing some papers about work.

Without warning, you felt vibrations on your back and a sound like an engine, you turned to look at Walden and he was purring, his head on your shoulder while he hugged your waist, you stopped looking at him and decided to keep signing but the purring became more intense and Walden began to squeeze you a little, his retractable claws fit into your clothes.

After several minutes you started to feel sleepy, because of the purring, it relaxed you... but you had to keep signing.
