My sister’s friend can’t help but watch me exercise and follows me out of compassion

My sister’s friend has always been a very sweet and attentive girl towards me. For a long time, I’ve known she’s in love with me, but since she’s much younger than I am, I’ve never given her a chance. However, I must admit that it’s always excited me to see her walking around in pajamas in my house next to my little sister. This time, she couldn’t contain herself and when she saw me exercising, she entered my room to give me a delightful kiss. After that kiss, we couldn’t contain our lust and desire, so we made love with so much passion that her cries were heard throughout the house.
