As I trained alongside our track team's ace, Rikugawa-san, my arousal grew uncontrollable. Her scent, soft breasts, and exposed clit made it impossible not to get hard while we practiced stretching and strength training together. When she bent over during one exercise, her bulging panties teased me so much that I couldn't resist pushing my throbbing cockhead against her wetness through her spandex shorts—just 1 cm inside! It felt like she was inviting me to fuck her! Soon enough, we both gave in to temptation; full penetration! My cock ached under the pressure of being buried just 1 cm deep within those tight shorts. As she rode me in cowgirl position, every thrust sent shockwaves of pleasure coursing through my body until finally... I exploded inside her! Despite having a girlfriend back home, there was something about Rikugawa-san that had me completely hooked. Keep in mind that recording methods may vary depending on the distribution method.
