i apologize for bad spelling and grammar, i am on mobile. i was hanging out with my month long girlfriend, we were making out, and it escalated. she gave me a blowjob for a while but i always last long when i masturbate so i knew i was most likely going to last long. we heard the upstairs garage door open like 8 minutes in meaning someone else has entered my home and i didn’t exactly want them seeing my girlfriend slobbering. this person turned out to be my brother. my main problem is that i have no way to control how long i last and so she thinks she is not performing well or isn’t satisfying me. i want her to know that she does a good job at satisfying me. is it bad that i didn’t finish? is there any way for me to finish faster? let me know please.
