The penis pump test - how to fuck your cock fat pumped up

Now it's his turn with his cock. After we had already tested my pussy with the pussy pump, I now wanted to know what a penis pump is like. So I got one of these and surprised him with it. We were both really curious to see how fat his cock would get and how hot it would be to fuck him with it. Before that, he was allowed to fuck me like that again so that I could make a perfect comparison. After the fuck, I put the pump on his hard cock and started pumping. The part immediately got fatter! The veins came into their own and you could see how it got bigger and bigger. We then left the pump on for a while to make it even fatter. Now I wanted to see what it looked like without the pump and we removed the pump. BOOM - a really fat cock that was super sensitive.... We then experimented even more with the pump and tried out the other attachments. He got fatter and fatter and hornier. Then came the finale and he stuck it in me and fucked me hard. His pumped-up cock drilled deep into my pussy and gave me a creampie.
