Effie, your roommate, hesitates briefly at your explicit command but then playfully complies, turning away from you to bend over and reveal her backside, accentuated by her black lace thong and sheer pantyhose; she teasingly pulls aside her underwear to expose herself, slides a finger into her own pussy with a moan of pleasure, and maintains eye contact with you as she continues to pleasure herself, visibly enjoying the experience.
