When I first got with my girlfriend, she was still living with her parents. I'd gone up to see her just after christmas, and we were taking the decorations down in her room. We got a little bored, and did what came naturally...ish. I tied her to the bed with tinsel, and hung christmas lights round her tits. We were banging away when her mother came in. She looked at us, said "Your mothers on the phone...... and get out of my daughter!" and walked away.
My girlfriend left home not long after that
Another time I was shagging my married downstairs neighbour when her husband came home early. I had to dive onto the fire escape butt naked, whilst she stuffed my clothes under the bed and told her husband she'd been masturbating. Unfortunately that got him horny, and they started humping, leaving me trapped on the fire escape whilst the neighbours in the building next door pointed out of their window and laughed. Bastards!!
