Now coming to Anu’s figure was a lovely 32-28-32. Even though we had agreed on the friends with benefits principle, she needed a push to get over th... line and actually be friends with benefits.The opportunity arose during a rainy day on our way back from college. We were on our way back from college and it started raining heavily, we had only one umbrella. My house being the closest, I told her to rush to my place. We reached my home, totally drenched.As we entered, I suggested let’s change. She has a bikini top on underneath, but still, it makes Sara a little uncomfortable.Her & Sara move on to equations & study those for about half an hour. Sara can't help but look at Mrs. James. She is however busty. She's a slim brunette with long silky hair & a big smile. Soon, Mrs. James begins to notice Sara's curiosity & approaches. "Shall we use the desks or the floor?" She asks."Pardon?" Sara responds with confusion."It's not like I haven't noticed you looking, Sara. Come on, no one's. Her hips were at window height and I could not really see what was happening except that there was topless bloke in the car. As I got closer she pulled away a little and turned towards me. It was at this point I could see the strap on extending form between her legs and the open mouth of the man whose head was at the car window. A lead extended from his small collar to her hand.With a wicked smile playing across her lips which I found slightly disturbing she asked “Is there anything we can. She backed off once more. This time when she leaned forward, instead of taking me in her mouth again, her head went down lower and I felt her tongue slide over my scrotum. Her mouth closed around one of my balls and she gently sucked, then switched to the other side. She gripped my shaft with both hands, working it while she carefully but thoroughly sucked and licked at my balls. Her hands were soft, her tongue was wet, and her breath was hot. I could have sat there enjoying her attentions for.
