when my girlfriends ex came over

A few years ago my girlfriend(Hellan 21) and I(21m) were living together in our house. one night her ex-boyfriend Jake came over to hangout with us. We were all relaxing having a few drinks and laughing and we all decided to head to bed. Jake stayed in the living room and Hellan and I went to bed, we got to our bed and she was feeling really horny so we got to business. shes kinda a BBW so sexy with all her curves so i stripped her down and softly kissed her neck i then i whispered in her ear

“why are you so horny are you thinking of Jake?”.

“maybe i am” she replied

“what about him” i asked as i kissed her neck

“his cock i want his cock its so big so much bigger then yours i just want it in me i want him to fuck me”

when she told me that i got rock hard and started to kiss her harder. she starts to moan as i start to kiss her tits and suck her nipples. i slid my hand down to her sweet shaved pussy and i can feel how wet she is. i slide one of my fingers in her and she starts to moan louder. i ask her
