I call Ria, an unassuming slender beauty with outrageously sexy breasts, over to my place again. She looks refined but is secretly a horny masochist. She seems to love me, though I have no intention of dating her; as a casual sex partner, however, she is exceptional. Whenever the urge hits, I use her on the bed, in the bath and at the entrance, pouring out my lust exactly as instinct demands in this record of utterly selfish sex.
