"My parents got me a personal trainer as a birthday gift, and I get so turned on during our sessions. I told him I want to build my glutes, and he really gave my ass a workout. We started off doing squats, but what I really wanted to do was squat on his dick. I saw he was hard so I grabbed his cock and started sucking it. He looked a little freaked out, but he didn't stop me. We started fucking right there in my parent's backyard. They could've seen us! And he fucked me in the ass too! That was the best workout I ever had."
