This is very similar to what happened to me when I visited my older sister. She is retired now but has a beautiful pool in her backyard. We decided to go swimming and after a few glasses of wine she coached me into swimming naked. She’s a voluptuous woman in the sight of her tits ass and pussy got me very hard. She was teasing me straddling my cock in the pool and she actually started tongue kissing meI cornered her against the side of the pool fucked her hard. We now have a relationship or whenever I visit her we have sex. We do not see the harm because we’re both adults
