First Anal
You couldn't feel the fag cum in you because he has a small dick and doesn't shoot very big loads.
No you can’t feel it shooting in. If he pulls out and unloads on your ass you can. The feeling of needing to shit goes away the more you do it. And yes, it becomes more enjoyable.
Back in my younger days in school I had anal and oral sec with quite a few boys and in high school my friend Terry had a really big dick. The first time he fucked me it hurt like hell but he came really fast and he came so much that I actually felt his cum shoot up my ass. He fucked me many times after that but I never felt him cum in my ass again but he always did and it was always a lot of cum
You honestly didn’t feel that cock head swell up and that warm gosh of liquid fill your ass? I gotta tell you I feel it every time and I can cum without touching my cock just from bottoming.
