[FM] My boyfriend “accidentally” slips into my ass!

F18 Me and my boyfriend M20 are very sexually active with each other. We each have our own favorite positions. Personally I like being pinned down or tied up, He likes to give it to me from behind. We both love all positions but we can both agree there’s some that we both enjoy more together than others. Missionary is a huge one we can agree on, were face to face I still get to be pinned down a bit and penetrated deeper than some positions, he gets so many options too like gazing into my eyes, kiss my lips, squeeze my neck, squeeze suck and bite my tits, grip my waist, look and touch my pussy/clit, and all while his cock spreads my pussy lips apart and thrusts in over and over again… Lost in thought reliving it… Anyway It should go without saying he makes me absolutely gush when we have sex.
