Am I to heavy to do this?

Wouldn't it be better to ask him this? He's the one you want to sit on after all.

115 lbs. isn't really heavy though, but it also depends on your boyfriend will feel. o.O

I would think he wouldn't have a problem with you sitting in his lap, but you know it's really up to him to let you know if he's uncomfortable, or help position you so that it's more comfortable.

If your hot im sure it wont be an issue. 115 is a good wieght for a girl
