A week after seeing my roommate Becky and her daughter Reagan have sex, it was time for them to do that with a strap-on. Becky would wear it, penetrate Reagan, and let her suck the dildo. They would switch roles next time. I sat on a chair facing their bed, which they sat on in matching tank tops and jeans.
They lip-locked and ran their hands down each other's arms. Reagan pulled Becky's top (she did not wear a bra) down and unbuttoned her jeans to put her hand in them to feel her pussy and kiss and suck her breasts and nipples. She held Reagan in with a facial expression of joy. She then knelt by the window behind the bed. Reagan sat behind her and pulled down her pants and panties to kiss and lick her buttocks and hold her hips. I wished I was doing that and felt aroused, but the genital surgeries I had kept me from having an erection. Becky panted, rubbing the window in joy. Her panting got louder, then she banged the window when Reagan licked between her ass cheeks, grabbed them and sucked her anus. Reagan knelt on the bed as Becky sat in front of her, pulled down her tank top (she wore no bra either) and unbuttoned her jeans. She then kissed and sucked her breasts and nipples and slipped a hand in her jeans to feel her pussy.
Reagan held her in looking pleased. Becky lay down as she took off her jeans and panties to suck her pussy. She held her breasts as Becky held her head and eventually orgasmed. Reagan kissed down her legs and thighs to her feet and sucked her toes. She lay facedown on the bed with her legs on the floor and ass sticking out. Becky sat behind her and pulled down her jeans and panties to kiss and lick her buttocks.
