HHKL-010 - My Innocent Little Sister is a Secret Nympho: Wild Rides and Non-stop Orgasms

My sister was supposed to be the perfect, innocent honor student, but it turns out she's a total nympho in disguise! After catching me staring, instead of being disgusted, she gets turned on and straddles me, grinding her hips with insane intensity. Gone is the shy girl I knew; she's now drooling and begging for it, riding me until we both explode. A wild, high-speed display of pure lust you won't be able to look away from.
