I am mortified!!

So I was round my S/O house the other day and he has a ten year old son from a previous relationship. So I’m alone with his son and he comes running down stairs crying saying he thinks he’s found something ‘inappropriate’ and he’s ‘sorry for going through the draws’ long story short he found a condom packet in the draw and I was mortified omg. My S/O thinks it’s hilarious but honestly I feel so embarrassed 😞
