Slavery: A series of erotic games (book 01)
This sounded much rougher than her past reading material.
Julia was tall, 5-9, blonde like me, hair to the middle of her back; legs down to there, lovely, soft, C cup breasts with nipples that became hard easily and were very sensitive and a perfect, round, athletic ass you could bounce a quarter off. She worked out doing Yoga, a spin class, aerobics and light weights several days a week to stay in shape, plus often swam laps in our pool.
