Just This Once with Step-Sister

Your girlfriend just broke up with you so you got Tipsy. It's very late at night when you show up at your step-sister's door looking for consolation. She begins to comfort you, but you've noticed she's not wearing a bra, and you're lonely, so you lean in for a kiss. Appalled, she pushes you away. She gives you a blanket & tells you to rest it off on her couch. The next morning you're still trying to push away thoughts of your ex girlfriend so you decide to alleviate your morning wood with a good stroke. Step-Sister walks in on you & she's pretty upset. She covers up your cock with the blanket, but it's still rock hard as she tries to talk to you. It keeps dancing around under the covers. It's very distracting for her, and you see an opportunity. At first she thinks that you were just doing your business, but then she realizes that you wanted her to walk in on you. She's dismayed & doesn't know what to do.
