Stepmom roleplay. Armpit/tit worship. You (stepmom) catch me (stepson) spying on you working out (bra). You get on to me, and then realize I’m looking at your armpits (raise your sweaty arms a few times before and then say “why are so hard… are you looking at my armpits?!”). Then you think it’s funny and laugh at me, then decide to let me fuck. Sitting on my cock arms up so I can see tits bouncing and armpits too. Then at the end tell me to impregnate you, to breed you.
