In the dimly lit gym, Ruby's workout takes a kinky turn. She peels off her sports bra, her perky breasts bouncing free. Her hands roam, caressing her curves, her fingers dipping into her tight, sweaty gym shorts. She imagines a hard, anonymous body pressing against her, her desire intensifying. Her fingers plunge into her wet pussy, her body arching as she fucks herself, her cries of pleasure bouncing off the empty gym walls.
