Making out

Sooooo. My boyfriend and I have been dating for 5 months and we’ve made out before but he doesn’t really like hickies. I’ve never had one but I mean I’d like to try....? Idk tbh. So this weekend we were hanging out and with all of his friends and i gave him a hug and sort of started kissing is neck. He didn’t know what was going on and then I was laying down and he started kissing mine and omg🤤💦🤤💦😍😍😍😍😍 he just kept kissing me and his friends were all staring at us and it was just amazing. But now he kind of does want to give me a hickie so where can he give me one without anyone seeing?
