My wife and I started practicing male chastity after our one year anniversary, and now we have been together for 15 years.

When we first met, my penis was 4.5" long and did not satisfy her. However, I still remember the first time I couldn't reach her vagina in the doggie style position. I should mention that my wife is 5'8" tall and weighed 125lbs when we met. However, she gained weight during her first pregnancy and reached 210lbs. She has since lost most of that weight and now weighs about 150lbs.

Two weeks before our baby was born, she told me that she was horny and wanted to have sex. She enjoys the doggie style position and had engaged in it with a well-endowed partner throughout her pregnancy. Now, it is important to note that her buttocks had become larger. She went from wearing small-sized Victoria's Secret panties before the pregnancy to wearing XL / XXL sizes.

On that day, she unlocked me and asked me to have sex with her in the doggie style position. However, after about 18 months of on and off chastity, my penis had shrunk to around 3-3.5" in length. I tried to reach her vagina, but her large and sexy buttocks were too big for my penis. Eventually, she said, "Oh my god, you can't reach it, can you?" I told her to wait and tried again.

This is when she got upset and said, "Here you have a sexy pregnant hotwife who wants her husband's penis, but it's too small to satisfy her." I suggested that I could perform oral sex on her, but she declined and said she wanted to be penetrated with a strap-on dildo in the doggie style position. She also handed me her wet XXL panties and told me to wear them. So, I put on the panties and the strap-on.

Then, I started penetrating her in the doggie style position with a 14" black dildo. She moaned and instructed me to fuck her large buttocks hard with that big dildo. I moaned in response, and she said, "Fuck me until I squirt." As I pounded her, she started moaning that she was going to squirt. My small penis was very hard. My wife moaned again, saying, "Yeah, I'm going to squirt."

Then, she began squirting all over my crotch and the panty-covered 3" penis. This was too much for me, and I moaned that I was also about to orgasm as we continued thrusting. She told me that nothing was touching my small penis and that my orgasm was a result of pegging her with the strap-on while wearing panties. She then said, "Now, lie on your back while I sit on your face and you can pleasure me orally. I will relock your penis and we can discuss our future plans, my little sissy."

As I lay on my back, pleasuring her with my mouth, she inserted the chastity cage into me. However, my small penis was still aroused, and I orgasmed as she was locking the cage, with minimal touch while I was performing oral sex on her. She laughed and commented that I came while she was locking me, suggesting that I enjoy being locked up.
