Who said you can't have your cake and eat it. In my case, they'd be very wrong.
My girlfriend is drop dead gorgeous. She's also a kinky horny bitch who adores sex and especially anal sex. We've fucked in lots of places, most recently on a coach whilst traveling through a tunnel in Switzerland.
Her mum is just as fit and beautiful and loves noting more than to entertain me, if her daughter is still out at work. When I say entertain, what I mean is, I fuck her all ends up and have often not long cum all over her amazing tits, which she loves me doing.

Finally the person who pays for all of our trips (My girlfriend and I) is her father. He's a business owner who likes his daughter to enjoy life, so he makes sure she travels a lot and it's always to beautiful places. He also knows his wife enjoys younger men every now and then and accepts I've fucked her many times of late.
He's so accepting because of my little secret. My girlfriend isn't the only one who enjoys anal sex. I too love to have a long thick cock fucking my arsehole, and my girlfriends father just so happens to enjoy sticking his long pole up my shitbox. He's even suggested I move in recently so he has easier access to my bottom.
Mentioning it to my girlfriend she was only too keen to say yes, but not as keen as her mum, who literally begged me to move in. Only she didn't just say it for herself, which nearly had me picking my jaw up off the floor. Gripping my cock through the shorts I had on, she told me "You can share my bed with Sean, he'd love it too I'm sure". Sean is my girlfriends dad. Now I know Sean's wife knows he's fucking me, but couldn't care less.

Where's the cake?
