Alexis has not given up the goal of sending you to heaven with the help of a big cock. He has just moved from the "poorly endowed" category to the "medium endowed" category. However, he needs more. Alexis puts the ring back on his new penis and validates the word "thick" he had chosen earlier in the app.
A few seconds later, he jumps because of the sharp pain induced by the swap. An uncut dick just appeared through the ring. Even at rest, you both notice a size difference. Moreover, Alexis is delighted to get back a foreskin.
No need to jerk off to get a hard-on. Thanks to arousal, you see this dick slowly straightening... and gaining width. Once hard, Alexis possesses a very thick cock encircled by the ring. You're both surprised at it doesn't point up, but stays horizontally straight. That's not all. Two large testicles are attached below.
Alexis weighs "his" balls in the hand to be sure they are real. He's never seen such big ones, except on the internet. Feeling them rub against his thighs gives him a funny feeling. This porn scene's vision makes you salivate. You kneel down to put his borrowed cock in your mouth. But, given to the object's size, you are forced to lick it greedily.
While you take care of him, Alexis wonders how it feels to have a package this huge in the underwear every day... Those big balls alone could be a constant annoyance. What if... Excitement makes him say "What if I try to keep it!" This hasty decision surprises you. But you agree that it would be silly not to try.
Now you realize you can't help him to keep that cock. If you put yours in the ring, you'll give a stranger your 8 inches monster and get your original 6 inches dick back. You need someone else! But who can you trust?
