Now things have fallen into a pretty good routine with plenty of time for them to do friend things while you still get some alone time with your girl. They go out for a day of shopping, leaving you home for some alone time with your VR headset and hot taboo porn. When they come home and seem to be up to something. They told you to wait in your room while they tried on what they bought. You were stunned to see them come into the room wearing similar see-through outfits. Your girlfriend explained that your stepsister has an idea for how you can all stay close. She thinks it would help if she could combine her bestie time with her fucking time and yes, that means a threesome with your sexy little blonde stepsister. Their outfits are so hot, you can’t keep your eyes off of their hot, teen bodies. They look like VR models from your movies. The girls still aren’t convinced though. They want to see if that cock of yours is big and hard for them. As soon as you take it out, they strip completely and get into bed together. You don’t mind if they play together first, do you? Your girlfriend assures you that your stepsister can’t wait to feel your cock and that she can’t wait to taste her best on your big hard dick. Don’t hold back, they want to see you cum while they do. Show them how much you want them and every hole they have is yours.
