A few years ago, I had a girl in her early 20s offer me a handjob or a blowjob once a week if I let her live with me. She LOVED giving guys blue balls, and I only ever came once. It was by accident and she slapped my "tiny testicles" until I cried for "getting cum on her hand". Even tho I knew how it'd end (painful blue balls) I still LOVED her fingers wrapped around me and often begged her to play with me a few times extra. I loved taking her shopping, because she'd model whatever I bought for her. Every few months, she'd "let me" cum but only if I did it myself and let her watch. She'd make fun of me while I was stroking myself, but OMG it felt so good!
