You had only taken your eyes off of her for a second, but before you could even react, you felt someone pull down your panties and push you to lean over the table behind you. You look behind you and see Yurina grinning giddily behind you as you feel her stick your former cock inside your new pussy. She manages to get a few good thrusts in before others catch on to what she is doing.
"Woah, hold on. I know this is all exciting, but you can't just do that to him like that Yurina. Though I do admit it is kind of a common occurrence at these parties, nonetheless..." calmly interrupts Ricky, however he doesn't get to finish as both you and Yurina both look at him with an annoyed look for butting in needlessly.
"Shut it Ricky, I wouldn't be letting her do this to me otherwise" You say. Yurina nods along with your statement. Both of you have understood that the other has harbored deep feelings for the other the moment you swapped parts. You normally are not gay, but your new pussy practically was begging you to fuck your former cock, and Yurina was feeling the same way about her former pussy. So even if the means are completely out of the ordinary, you can now happily say that the two of you have satisfied some of your longing desires to fuck each other.
You do not even care that 10 other people are watching you get fucked over a table from behind by a girl with a cock because you doubt that you will be the only pair this night to be getting some action. So while you and Yurina continue fucking, the game continues as well. In fact, the other participants have taken an interest in the two of you and seem to all decide to have some fun with it.
They ask Ricky if it is possible to do all of the two of your swaps first, and let you go on uninterrupted before the rest of them do theirs. Ricky thinks it over and nods, saying that he can make it work, much to their delights. You are chosen to be the first target, and end up getting paired with another girl, Emily.
Emily is one of Yurina's friends, though their not so close to be considered best friends. The main reason behind this was the friendly rivalry between them. This is because while Yurina has an amazing ass and legs, she is almost flat as a board. The opposite can be said for Emily though. Emily isn't exactly the tallest girl, nor the thinnest. She isn't fat or overweight by any means, but she can't be considered to have a weak and fragile body either. However, she has an amazing pair of large boobs that make up for the rest in most people's eyes.
The two girls lock eyes and Emily announces that she would like to have your shirt, then comments, "There, now at least one of you has tits" when Yurina gives her a displeased, but knowing look. Yurina does the swap for you, and puts the bra on for you since she is behind you and can do the clasp easily for there. You feel the pair of F cups push you up off the surface of the table, now letting you rest on top of them like two perfect pillows. Each having just the right amount of firmness to still be considered soft and bouncy, yet not enough to really start to sag either. Emily walks over and helps herself to your new tits for a quick feel before Yurina stops her.
"Now now, I am just making sure he is all set and to say goodbye to my girls for a while" says Emily, who then hands Yurina something that you can't see, but clearly causes Yurina to react in a shocked manner. "Just put them in if you want to. I know for a fact that they enjoy having them in, but that is up to the two of you to decide. I will say though that they make things quite more interesting if you get a little bit rough with them in, though do be careful as you can pull them out if you are too rough with them." Casually explains Emily before giving you a wink and taking her leave. "Thanks, I think?" Says Yurina awkwardly, before returning her attention back to you and placing the pair of golden nipple ring piercings down onto the table next to you.
