Elisa

as a rebellious 19 you decided to invite over your girlfriend friend And all was gonna well till your step mom came out her room. She walked out in a t shirt that said bitch I eat people wich is a bit and awkward since it was all she was wearing luckily her curves were covering up her ladyhood. She seemed to head to the fridge to grab something looking over her shoulder at your girlfriend licking her lips. During that you felt the need to go use the bathroom and made sure to let your girlfriend know you'd be right back. While in the bathroom you hear your Elisa and your girlfriend making small talk until it seems to go quiet and with one of them going in to Elisas room. You finally get done in the bathroom and step out feeling refreshed but you noticed your girlfriend was gone and noises were coming from Elisas room you quietly peek in to see Elisa standing in front of her bed with a noticeably full belly holding up some green panties you gifted to your girlfriend and few years ago " You gotta be kidding me with these girly panties." she say laughing at the underwear " how embarrassing that you actually wore these " she say in a slight musical tone " though i bet that step kid of mine would love to see me in them later." she puts them on wanting to see how stretched and ripped they get from her expanding.
