With my tired eyes closed I reach out and grab hold of my husbands erection.. my god its been ages since he.. wait a second.. oh fuck.. what is my step-SON doing in my bed? I just touched my own step-Sons penis.. how embarrassing! He tells me he's in need of some company as his girlfriend has just ended the relationship and he's heartbroken.. my poor boy! I knew she wasn't right for him.. but I can't get how BIG his cock felt in my hand outta my mind.. I "accidentally" pull back the covers and SEE just how massive his erection IS! HOLY.. FUCK.. is it getting hot in here or is it just me? I don't know why.. but I reach out and put my hand around it again.. this time as his step-Mommy KNOWINGLY touching her own step-Son in between his legs.. I stroke him slowly, whispering.. I can't believe we are doing this.. and then before I know it I'm on my back and he's trying to squeeze himself inside of me.. what the fuck.. WHERE did this sudden lust come from? I can't explain it.. I'm having sex with my step-Son whilst his step-Dad is downstairs.. and all without protection.
