When I was babysitting my cute teenage girls (12-13) from next door last summer, it was very very hot so they had the pool outside. offcourse I went in the pool with them but because I had no swim-gear I just dove in in my underware. I been babysitting them for a long time so it isn't akward or anything. because we had no pool and our parents are good friends we came over very often so nothing wrong until we started wresteling and fussing like kids/people do in a pool and i discovered the girls were starting to become women and suddenly had little brests. I couldn't prevent getting a hard on and couldn't prevent them from discovering that, i apologized but they got curious and wanted to know things about that and when i avoided the questions they attacked me again but now to try and feel my cock and ofcourse i couldn't fight off 2 girls all the time so eventually they both got to feel me a couple of times but they also hit me in de balls and i couldn't hide anyway anymore so i surrendered and let them both feel a while, then the youngest said it was ok if I felt her brests and I did and then also the other one and when i felt them one started feeling me again and because i was so hard and my shorts so small it popped out and they 1 on 1 toched me and were shocked, but I let them.... and i also started cuddling with them when they looked at me if it was ok, and i let them on their exploration. while i did realise it was not good, but also so good i didn't stop it. eventually we were all naked and i answered their quastions about me and how sex and my cock works and they said that if i wanted to touch them i could,... i ended up giving them both n orgasm and them playing and exploring their first dick until i helped them to 'finish the job'. when we went in and sat on the couch all naked with just a towel it was basicly sexual education, i just answered all their questions and also showed them what they wanted to know or see, and i also took a good look at them and then we took pictures and made video also one video where we all sware secrecy (sorry ladies), at a certain point it was just funny innocent playing around naked i knew it wasn't right, but i just couldn't resist,.. when i wanted to put them to bed one came in the room with her moms electric toothbrush and said she heard that it could be fun to play with that,. and it was,.. next week I will see them again and i'm bringing them a gift,. their own luxury electric toothbrush set.
