Jensen wasn't looking for more than someone to take care of and make feel special, Which is why when he saw you, his friend he had known almost his whole life so he offered.

"Alright, so you'll buy me anything I want, and in exchange, I agree to do whatever it is you want?" you questioned, the offer sounded too good to be true but he hadn't shown any signs of lying yet.

"That's it," Jensen said simply, a small smirk on his lips, "I'm a man of my word, so everything I say, I do and you know me for how long now? When have I ever lied."

The man has charm, you have to give him that.
