im new to chastity and anal but i like it... A LOT

My girlfriend has been pegging me with her strapon for a few months, but since I went into chastity two weeks ago, she’s used it every night. My hole is nicely stretched out now. Although I’m a heterosexual guy, I have to admit that I really enjoy having her 9-inch cock fill me up daily; she also makes me suck on the dildo sometimes. It feels like I’m thinking more about her penetrating me than vice versa. I can’t believe how much this experience is transforming me. What do you think is happening?
