My twin sister and I became closer than ever (PART 9)

Reminder: I'm M20 and she's F20. I previously said I watched DEBS with my sis, and she got her ass over me, which made my boner deep into her. She told me to unlock her bra and sleep together

As much as the situation became a movie-corn-type situation (and every guy in the comment section just telling me to bang her), there is still this morality in me. I'm not a guy who wants to have incest sex just because I find my sister hot. Sure I bang her in my dreams, but IRL when it's about to happen, it's like 99% of you wanting to just rail her, and 1% in the back of you head saying you will regret this your entire life.

Anyways, as we headed into my bedroom with lights off, my sister was now topless. No bra, which means, her voluminous breasts were like two footballs hanging. She wore a tiny short instead of the previous one. I'd never understand why girls like her with huge ass wear shorts designed for M size while her butt clearly is a 3XL?? Like I know the whole thing is super sexy but is it really comfy???

She was pretty tired so we kissed again "to train me" (but i think she was just horny-tired). She put her back on my size, I felt like spooning was the best thing to do. Her milked boobs were naked on my bed, I managed to wraps my arms around them and touch how soft they were, I asked "is it okay Sanaa?", she replied "dumbass you've seen me topless many times" (I don't think I ever did). Now her massive ass in that dying tightened M-sized short was directly on my erection, so it's all over the same thing again. I kept getting sweaty at trying to control myself, my back was wet, I asked her if I could take off my clothes (it really was hot too, we didn't have a blanket and windows were open). She was half asleep, she mumbled "I don't caaare fuck"

I took off my tshirt and strengthened my grip onto her. I wondered if "not caring" applied to my shorts. I took them off anyway. And I was struggling to keep my hungry cock to rub on those thick walls
