My grandpa has been married to my grandma forever but never really knows what to get her. He either doesn't get her anything or gets something she doesn't like. So... I figured my gift to him would be a gift to her. Getting her something she likes that he can pass on his own. I told him to come over to my place alone when he got the chance, so she wouldn't know it actually came from me.

Fast forward, I was taking a shower and after I like to air dry... so I just go around naked. I never really think to lock my door during the day so it was open. But... my grandpa came about an hour earlier than I said to meaning he walked in and saw me completely naked. I immediately froze but he had a huge grin on his face and started to walk over to me. He said something along the lines of "Now I know why you wanted me to come alone" and told me this actually was the best gift ever. He started to feel me up too. I was just in so much disbelief seeing how happy he was it and the fact he thought "this" was actually his gift that I didn't have the courage to tell him it wasn't!
