I do some group scenes with this Domina I know for the last 15ish months or so. One of her main things is forced bi with boy subs and she also includes female subs in her group stuff too. I've grown to really enjoy watching her do the forced bi as well as taking part and helping them with it and also offering up my body as rewards for them doing forced bi things. During a group scene last May as reward for doing things with the biflex "Daddy" top she included in the scene with 2 of her baby boys she let the boys and well as the Daddy too feed on my boobs a ton that day and at one point the boys were sorta competing to see who could leave me the most marks. Well since they left me lots especially in the same area on my left tit and they all swelled up and sorta merged together to leave this huge as bruise mark on my tit. I definitely burst some blood vessels cuz it took a while to heal and go away also left a bit of a knot under my skin for a while. Which isn't the best. I would definitely do the same scene again as I love my tits being sucked on a ton like that but probably would have them space things out and not let them suck hard on it for as long as they did to prevent the injury again.
