My girlfriend ( 19 ) Gave a blowjob to a park worker ( looks like he’s in his 40’s ) in a public park today. [MF]

so me and my girlfriend have been on and off about this sharing stuff, we both have a fantasy for her to be used by another guy but we always back down and not do it because we get too scared. but today things changed, we’re in an online relationship so we were trying to have some fun, so i told her to go to a park and she’ll have to walk around in it with her tits out. So she did as i said, She was walking around the park, it was really empty due to the time she was out at, so she was walking with her tits out, chatting with me, and then she sees a person, she gets nervous and embarassed but keeps walking, the person was wearing a kind of vest and seemed like he worked at the park. He stared at her and then asked her ” Can you let me touch?” and she said Yes, he started feeling up her tits, Touching her all over and pinching her nipples. all she did is moan like a slut. he then pulled her by the hair and got her on her knees, asked her if “that’s okay?” and she nodded. She was getting soaked wet. He said lots of things about her. how beautiful she is. how gorgeous she is. how naughty she is to be doing this and how he hasn’t seen such a teen slut in a while. She gets on her knees and he unzips, my girlfriend is a complete virgin so she gets really shocked due to how big his cock was.
