I [F] Accidentally Ruined the Greatest Orgasm of my Boyfriend’s Life

This is my first story so any feedback is appreciated :)

Descriptions:
Jack: 5ft 11, white, green eyes, short light brown hair, slim, fairly broad shoulders, toned, about 6 inch dick

Me: 5ft 6, white but lightly tanned, brown eyes, long dark brown hair, flat stomach, very small waist, pretty big hips, fairly thick thighs, perky bum, 34DD boobs

My boyfriend, Jack, and I (both 18 years old) have been in a loving relationship for a while now. We really get on, make sure we’re there for each other, go on cute dates, etc.

A little while ago, my parents were going to be gone for a day, meaning I had the house to myself. The COVID restrictions were quite lenient in my area at the time, so Jack and I decided go out for a nice dinner then go back to my house with a mission: to have the best sex a couple could ever have! Our sex was usually great, but could we go the extra mile and give each other an earth-shattering experience that would make all previous and future sexual experiences pale in comparison?
