My girlfriend's stepson solicits me to expose my breasts so he can pleasure himself in my presence and climax

The other day, I dropped by my girlfriend's place. Her stepson greeted me at the door, looking rather eager and excited. It turns out he had been waiting for me, and he had a rather unusual request. He wanted to see me naked, so he could pleasure himself in my presence. Being a bit of a naughty one, I decided to indulge him. I stripped down to my bra, revealing my perky assets to him. He wasted no time, his hands quickly finding their way to his pants. He began to stroke himself, his eyes never leaving my breasts. The sight of him pleasuring himself while staring at me was incredibly arousing. Before long, he was moaning in ecstasy, his hand moving faster and faster. With a final gasp, he climaxed, his warm cum landing on my stomach. It was a rather bizarre encounter, but oh so satisfying.
