I rushed into the bicycle parking lot with my female classmate due to an unexpected sudden heavy rain! We were both drenched and her flashy underwear was completely visible! I couldn't suppress my excitement and attacked her! Her bra was clearly visible through her tight-fitting uniform! I massaged her breasts and smooth thighs! When I undressed her and teased her sensitive nipples and private parts, she lost control of her bladder!? I inserted my erect penis into her drenched vagina! I kept hard thrusting until she had a full-body spasm and reached climax! Finally, I came inside my classmate who had been cumming non-stop!!
