Open Relationship
You’ve lost your house key so you’ve gone to your hot next-door neighbor’s to collect the spare key. She’s rummaging through her drawers to find it but while she’s looking for it, you’re getting to know each other a bit better. You tell her that you and your wife have a very open relationship and do a bit of swinging. This excites Dolly and can see you eyeing up her tits, and she can also see your hard cock!
New Material
Your step-sister is asking you a favor. Could she please borrow your suitcase? Being the annoying stepbrother that you are, you tell her no. But Ivy knows you were just having a wank before she came knocking on your door. So what if she gave you some new material to wank to? And in return, she gets to keep your spare suitcase!
