You look in utter horror as your Dad begins to take off his jeans revealing a
huge jockstrap with the slight impression of his dick. It seems your Dad wore jockstraps instead of normal underwear occasioanlly and the sight of his package makes your dick throb with anticipation.
Your Dad walks over to the guest bed you're currently on and takes off his shirt before sliding down his jockstrap to reveal his erect dick. Due to the condom changing you into Dad's twin brother and the fact that you had just saw your Dad naked earlier his dick isn't much of a surprise but the feeling you feel coming from your dick is. You haven't felt this horny in a long time even in your original body.
"I guess since you're the guest I'll do the work" your Dad says and climbs onto the edge of the bed before lifting your legs. ""Wait!" You utter in desperation. Although this man wasn't your REAL Dad, the idea of having sex with him repulses you.
"Maybe we ahoudln't-" you begin to say but your Dad or Twin Brother enters your ass anyway. "Wait! Dad... I mean Bro" You exclaim in panic before you feel a wave of new memories overtaking your old ones. Before you were Scott, a 14-year old boy, now you were Jay the twin brother of your former Dad. As you struggle to claim onto your original memories from your real body you find your memories of Scott diminishing and replaced with memories of being Jay.
Fortunately, you still retain the memories of your original body. Perhaps the condoms only alter reality and inplant new memories into the user without removing their original identity. As you continue to ponder the capabilities of the condoms you feel your Dad reach inside your ass completely after his dick enters.
"FUCK!" You shout in pain. The sensation is odd and discomforting. You've never had sex with a man before and you never knew that when you did you would be having it with your former "Dad". Your dick continues to leak pre-cum as your Dad fucks you. You feel both disgust and pleasure and it appears that only one was slowly overtaking your body. Your Dad fucks you nonstop and you begin to enjoy every second of it until you both reach a climax and cum over each other.
"Nick, that was amazing" You say to your brother. You were no longer disgusted and enjoyed the sex after all. The two of you cleam the cum off of each other's body and redress. Surprisingly, your clothes had changed once more and you find yourself putting on an identical jockstrap and clothes to your brother.
The two of you head downstairs after changing and you enjoy a nice meal with your brother, his wife, and your nephew. After dinner you head back to the guest room upstairs and spot the box of variety condoms.
They were now stored back in the box and under your bed (perhaps when reality changed they shifted under your bed). You open the box and place them all over your bed and notice the time. It was getting late and you didn't want to change into anymone new for the day. So would you rather stay in your new hairy dad bod or turn back into the pre-pubescent Scott?
