I Fear I've Caused More Than One Miscarriage

I have a big cock so I fear I've caused a few early miscarriages with my trademark rough fucking.

For sure I caused one fairly late miscarriage, maybe technically an abortion by that time. She had left the father and I hated him as well as the way he treated her, so I did not feel bad. Soon enough she was pregnant again, this time with my kid. She and I are not together...it would never have worked long-term...but we remain good friends.
