She runs off embarrassedly

My tutor stood up and looked down at herself, realizing how thin her shirt was. She looked even further down and realized the wet spot she had on her shorts. I looked a but more carefully and realized that there were no panty lines and that she must've gone commando. Before she looked up I made my eyes look at her face.

She looked up at me and I asked casually, "What's wrong?" I was pretty convinced at this point she had sex with her husband before she came out to meet and threw on something quickly.

She started to look more carefully at me and her face was growing more and more red, she replied back shakily, "Nothing, sorry it must been rude for me to ask if you had a girlfriend."

"Nope it's fine," I start, "I just was surprised you asked. I guess all the girls in my school are a bit immature and I'm not really interested in that." I answer truthfully without revealing the whole story.

She still was standing up and started to fidget, obviously getting uncomfortable with how revealing her clothes are. She was pushing her shirt forward to make sure her tits weren't standing out but with how big her tits her, those attempts were failing to conceal what she had underneath. "Uh... is that so, so you are looking for a mature woman?" She must've realized how that sounded and tried to backtrack, "I mean not in that way, just... you know..." She was trying to be conversational and not trying to tip me off with how revealing her clothes were.

I interjected, "Yeah I know what you mean. Maybe I'll find someone soon."

She gave a sigh of relief, "Yeah, thanks for understanding," She started to move towards door whilst trying her best to cover up without looking suspicious, "So... Uhh... There's something I need to do... Uhh... I think I left something on the kitchen... Yeah, I left something on the kitchen, I'll just be out for a minute."

She turned around quickly with her boobs bouncing around and moved to leave the room.
