On rainy days, the track and field club's main activity is starting practice on campus, but this is just so erotic and awesome! The female team member's firm, protruding ass jiggles every time she moves, and I can't stop getting an erection! I thought, "Maybe she's inviting me?" and pressed my erect cock against her ass, then pulled down her pants and inserted it raw and came inside her! Just when I thought it was dangerous, she spread her ass wide and squeezed my still-hard cock between the cracks of her ass, inviting me to cum inside her over and over again!
