We were hanging out with a few friends (2 girls, 4 Guys, all around 18/19) at a friends pool. 1 Guy (lets name hin Tom) and 1 Girl (lets name her Anna) were in the pool while the rest of us were hanging around near the pool. While I was standing near the pool, Anna came out and wanted to pull me into the pool. She was wearing a bikini while I was in a short and tshirt. We were playfighting a little bit when I told her I didnt want my clothes to get wet.
“Then take them off!”, she said. So while still playfighting I took off my shirt and she helped me take off my pants and threw my clothes inside. Then finally I gave in, grabbed her and jumped in the pool with her, just wearing my tight black retro boxers. Meanwhile Tom convinced the other guys to also jump in the pool, so they did (both fully clothed). The other Girl (Jenny) was standing besides the pool in skinny jeans, heels and a top and was watching us.
