Stepdaughter

In my previous relationship my ex had a daughter who at the time was 22 years old . She used to walk around her house in tights and tank tops with no bra all day and when her mom got home she would always change and cover up . This went on for a while till one time her mom went to a training and was away for 2 days . We were watching tv and when i looked her tit was out of her shirt and she acted like she didn’t notice she saw me looking and put it away but didn’t act shocked or anything. A while later it happened again so i jokingly said might as well leave it out now , she didn’t hesitate and took them both out like nothing . We didn’t have sex but we kissed i sucked her titties while she jerked me off till i came on her tits . It didn’t happen again but I’m cool with that .
