He didnt cum ?

Hi,

Lol i feel really weird after last night. I sucked my boyfriends dick for like 20 minutes and he didnt cum, and his mom ended up texting him to come home in the middle of it so he couldnt finish. He also wasnt moaning or anything during, he was just watching the tv i think. But his dick was really hard and he kept touching me. I couldnt really tell if he was enjoying it and i was just wondering if yall had any advice ?
